has anyone tried the $35 amplifier that rivals the high end amps. I was just reading about it on forbes asia magazine(3 oct 2005 issue)
Anyone tried it? How is it?

Let's start a thread on modifying and tweaking the t-amp and other class d amps.
I've made all the tweaks possible with the t-amp and have been using it as my main amp for the past 4 months already. For starters and for the biggest audible upgrade, change input caps to polypropelene or blackgates. Problem with higher uf caps for input, you get a startup "thump". But you gain deeper bass and less harsher highs which. You may also want to recase the amp and use better wiring and terminals. Also try upgrading the PSU cap, I've attached 3 big caps, one 6800uf as the first cap connected to dc power input, then two 150uf ata, soldered directly sa pins ng Tripath chip. I also changed one of the resistors to change the input gain of the amp to around 12v. I also attached a heat sink to the tripatch chip, the newer models don't have a lump of solder underneath it for heat dissipation, so naisip ko mas makakatulong pag kabitan ng heatsink. For a more detailed list of mods available, please check www.michael.mardis.com

happy nako sa Sonic-T ko, I use it at the office with an I-pod. pero these tweaks are tempting, makakuha kaya ng isa pa ;D

Forgot to mention that class-d or so called digital amps like smps (switching mode power supply) more than linear PSUs, so those contemplating on buying 12v 3ampere regulators may also consider using laptop PSUs. :) Also, for those who are into DIYing might be interested in trying out the amps at www.41hz.com and try their amp6 or amp3. The tripath chip used in these models are a definite improvement over the sonic impact t-amp. Yeo at DIYpararadise is also selling a kit based on the ta2020 chip (similar to amp6).

congrats sa mga mods mo bro.
unfortunately I disagree with the smps being favored by class d amps. I did tried powering the amp3 that I built using smps but to my dismay the highs were all over the place. >:( I also tried the t-amp with smps but have gotten a sort of high frequency oscillation which I thought can be remedied by proper shielding. However, the real best psu was the good old battery. A fast regulator comes in second.
how's your amp3? tumutunog na ba?
Just me and my 2 cents.
-
jojo, me amp3 ba na available? i need 2 :)

jojo, me amp3 ba na available? i need 2 :)
I'll inform you, ask ko muna kung meron.
musta flying moles?
-
Amp6 binili ko nung nasa States ako. Onboard voltage regulator. :) Pag tumunog may laban dun sa Charlize ni Yeow, well according to Nuuk, been exchanging notes with him during our assembly of the amp6. Regarding SMPS, there are different views on the matter, others swear by it, others experienced the same thing you said, harsh highs and weak bass ang general comment, pero depende daw sa SMPS na gamit.
-
Yep, it totally depends on the smps you use. But still, everyone who listened didn't liked it so I have no choice.
Wow amp6, maybe my next project is an amp2... maybe.
Nabuo mo ba yun tinatanong mo sa akin na regulator nun nagkita tayo?
-
i've been following the charlize thread sa diyaudio. nuuk is using an smps that he obtained from a supplier in uk, he swears by it.
-
Bumili nalang ako ng 12v 3 amp para sa linear regulation, tapos kinabitan ng voltmeter para may reference pag turn on ng power kung mataas o hindi. Advice ni Nuuk wag na yung zeener or any thing else idagdag pa, malinis na raw tumunog at wag nang kabitan pa ng ibang components.
-
So diyan pala yun binili mo na voltmeter...
Pinag aralan mo pa ba yun crowbar circuit na tinuro ko sa iyo? O protection scheme na ng linear regulator ka nag rely?
-
setup :
stock sonic impact t-amp used as main amp (front channel) ;
yamaha avr - used as preamp/ processor;
source - pioneer dvd player;
b&w601series 2 (fronts) ;
wharfedale diamond 9.1 (used as center speakers on dvd movies)
no surrounds (small listening area)
MS subwoofer (used for dvd movies only)
***
used this setup to play concert dvds and dvd movies - BLEW ME AWAY! :o :o :o
TAOB - Nadc320bee and sony ta-n330es amps ko!!!
to hear is to believe ;D
just my mamera 8)
-
Yes sir, pinagaralan ko yung crowbar network. Pwede ko lang syang gawin if I will DIY a separate regulated PSU section for the tripath amp, however, people said that the amp6 board was already well designed, where the PSU section is almost next to the tripath chip with very minimal distance between them. So I used the onboard regulation nalang. Napagisipan ko lagyan ng zener diode as bypass on the very last filter cap before the tripath chip since this is easier to implement. Di ko narin natuloy because maingay daw ang zeners. What you think Master Jojo? Btw, hinahanap ka ng may-ari dun sa Golden Mars, bakit di ka na raw dumadaan. hehe
-
as much as possible iwas sa zener lalu na pag shunt purpose lang gagawin mo. besides maliit lang nagagawa nito.
papasyalan ko din siya one of these days... miss ko na sila eh. ;D
-
great item this amp.
got one and i tried powering a pair of high sensitivity definitive technology bookshelves.
that turned out ok. but lacking in bass. obviously on account of the speakers. so i tried it
next with dynaudio bookshelves. holy crap! the bass simply oozed. i no longer believe you
need high sensitivity speakers for them. of course it wil help since i noticed you can turn
the volume a tad lower if you use high sensitivity speakers.
i took the advice of big bro oweidah though and got the 6ampere zebra power supply and
hooked it onto a car-cigarette-lighter-type of cable.
dang these babies sound really sweet. perhaps it is just the appple of my eye right now,
oer perhaps it simply sounds very nice, but i am playing my t-amp more often than my
jolida tube amp right now.
quite impressive. to think per oweidah, it isnt burnt in yet.
-
hey guys,
i bought myself a 6amp power supply, and chose it over a 3am power supply. i though it
was just a few hundreds more so why not take it. so now i am wondering if those extra
3 amperes are making a difference in the sound of my t-amp.
thanks
whip
-
whipsaw,
hmmm t.amp @ ease w/4ohms!? ... dyns are refuted to be powerhungry speakers yet t.amp's happy with it :)
enjiy d flavor of d month ;D
-
Nope. At 4ohms, RMS power of the amp is 15w (assuming you're comfortable pushing the amp at 10% distortion), that's 30w for both channels, then given the efficiency of the amp, around 80%, that should be be around 36watts maximum, for 12volts input, around 3 amperes should be sufficient. For 8ohm operation, it can be lower. How much did you buy the PSU? SMPS? Regulated? To have a better improvement, do all the mods possible on the amp. The stock amp starts to attenuate bass at 100hz.
-
i've been following the charlize thread sa diyaudio. nuuk is using an smps that he obtained from a supplier in uk, he swears by it.
why not? the t-amp is a digital amp, compared to the gainclone which is a linear amp, linear amps are susceptible to noise from psu, not so with digital.
-
@ oweidah & whipsaw
sir, what store po ba dito sa pinas meron nitong sonic T-amp? ive read reviews on this small but terrible portable amp and the reviews are quite nice. hope meron dito nito. thanks
-
@ oweidah & whipsaw
sir, what store po ba dito sa pinas meron nitong sonic T-amp? ive read reviews on this small but terrible portable amp and the reviews are quite nice. hope meron dito nito. thanks
afaik, not available in stores. check out the pinoydvd/assorted buy and sell/ht equipment thread.
-
thanks bro :)
-
Been using 2 sonic Ts to biamp my diamond 9.1 ....... huge sound improvement compared to using 1.... maybe because the speakers are now being driven properly (only 86db sensitivity)... Im sure tweaking the 2 T amps
will improve the sound further but dont want to take the chance as I have zero soldering skills.
-
ding45,
paano bi-amp set-up mo? naka-pre-amp ka or y-connector lang from the source to the two(2) t-amps?...tnx
-
sir oweidah, I'm using a CA Azur 540A as preamp... I put Y connector on the L/R pre-out.... one amp is driving
the tweeters and the other amp driving the mid/woofers..... Actually the signal coming out the pre-out is split 3 ways as I also have connected a subwoofer....
-
sir ding45, thanx...btw what power supply gamit mo for the t-amps? tag-isa sila powersupply? (since you mentioned using two(2) t-amps)...tnx
-
Using 2 power supplies 12V, 1A... bought from Handyman Store at Waltermart
-
ding45, thanx.
sirs, pwede kaya isang regulated power supply (12vdc)/3 to 6amperes - powering two(2) t-amps; one via cigarette lighter socket and the other via the red/black(+/-) terminals?
-
sirs,
tanong ko lang po kung saan pwedeng makabili ng IC (2024) na nakalagay sa Sonic T-Amp or yung halos katulad na IC nun ? Balak ko kasing mag assemble na tulad ng T-Amp but with the modifications.
Thanks.

If you're planning to use 2 sonic t-amps with one PSU, around 4 amps will do pag 8 ohms yung load or 6 amperes pag 4 ohms ang load.
-
What does "starts to attenuate bass at 100hz" reaaly means?
-
If you're planning to use 2 sonic t-amps with one PSU, around 4 amps will do pag 8 ohms yung load or 6 amperes pag 4 ohms ang load.
thanx alot sir DOHbert!!! :)

Attenuate means bumababa na ang db output from 100hz. Thus kung makinig ka ng music na may double bass or yung mga mababa ang tunog ng instrumento, mahina na ang output ng amp with respect to 100hz and frequencies below that. The sonic t-amp is down 10db at 20hz. Ang "bass" na nadidinig mo from stock unit is not as "low" and impactful as that after tweaking the input cap. Maynard PMed me on what tweaks I did and what parts i used. Basically, they are as follows (in order of preference, ie, biggest difference sonically):
1) Increase the power filter caps from the stock. It's that capacitor stacked in between the 4 inductor filters. Nilagyan ko ata ng 1800uf 35 volt panasonic caps. (effect of bigger filter cap is bigger reserve pag biglang nangaylangan ng lakas yung amp from the PSU, generally, the bigger the better, pero if its too big, bass will seem to slow down a bit ... daw)
2) Changed R4 and R5 to 20kohms (or 22kohms) para ang gain is set to 12v, but what I did was solder the resistor directly to legs #10&11 and #14&15 of the amp, the shortest connection to the chip the better ( I used 1% metallized resistors here, 1/4 watt ata)
3) Changed input caps from default value of .33uf to 2.2uf and soldered this directly from output of volume pot to R1 and R2 (walang pambili ng auricaps, used polypropelene's instead, still better sounding than the stock, highs are not as matinis, mas malambing tumunog and details are mas litaw)
- explanation lang kung bakit kailangan yung tweaks #2 and #3, the capacitor together with the resistors form a high pass filter, and the cutoff frequency is measured as follows: F=1(2*pi*R*C). Thus, Cutoff=1(2*3.14*20000*.0000022), which results to 3.619hz ang cutoff (ideally cutoff freq is at least 2 octaves lower than the lowest frequency expected, thus kung 20hz and lowest expected na tumunog out of the amp, 20hz-10hz is the 1st octave, 10hz to 5hz is the 2nd octave, so yung 3.619 natin is more than 2 octaves lower pa nga). But with the stock .33uf na input cap, cutoff is around 24.154hz, so ang attenuation (reduction) ng output ng bass is 100hz (db reduction) kasi 2 octaves above 24.154 is around 96-100hz. Hope you get the idea. Caveat pala, after increasing input cap, you will definitely hear a turn-on thump na di mo madidinig before with the small .33uf caps, wag lang mabibigla. :)
- regarding the Rfeedback, ginawa kong 22kohm (or 20kohm), basta same measurement as RIn (R1 and R2) para ma set yung gain ng amp to 12v ata. Effect: Parang mas mahina yung output kaya the need to increase the volume output via volume pot, pero ang maganda dito, hindi sya madaling ma over-drive ng input mo.
4) Changed all the wirings inside using cat5, read somewhere the lower resistance the better for the t-amp or digital amp in general
5) Changed volume pot to Alps
6) Used gold plated speaker binding posts and rca inputs
7) Nilagay sa maliit na lalagyan
8) Pagnagsawa, bumili ng Amp3 or Amp6 from 41hz.com. Way way better than a tweaked sonic impact t-amp. Kala ko malinaw na yung t-amp, pero nung pinatugtog ko yung amp6, meron akong nadinig na di ko nadinig sa t-amp. :o
-
yeah dami nga websites for t-amp tweaks at tweaked t-amps...
re-boxing muna ako for now kasi i'm happy using t-amp with acoustic research tds202 (AR tds202)
great combination!!! ;D
-
Big thanks to the T-amp master.
-
DOHbert, have u tried the Charlize from a certain Yeo? Do you know anyone selling it here? TIA
-
oweidah, In case you want to try biamping, I forgot to mention that in my biamp setup the reverb seemed to have increased a bit... I still find the sound OK but I dont know if that would be acceptable to your ears. If you are using a different set of speakers maybe you will not experience this...
-
ding45 thanx for info. flexible t-amps, dami pwede tweaks at configuration...
-
Sorry ding, I'm using a amp6 from 41hz. They use the same ta2020 chip, much cheaper than Yeo's Charlize, and according to Nuuk and the guy that maintains the www.michael.mardis.com site, both amps are very much similar in sound. Nice thing with the amp6, on board na yung power regulation. Just assemble and add a step down A/C trafo, ok ka na. :) Yung site ni Yeo is www.diyparadise.com. You can place your orders there then have them shipped, based sya sa malaysia. Another option are the UCD amps, check http://www.hypex.nl/main.htm. They are still so-called digital amps, but much much more powerful, required if you have low efficiency speakers and play loud a lot.
-
OK, thanks for the infos DOHbert...
-
Is it safe to use the 13.8V 6A DC regulated power supply to the T-amp or this is really 12V meron lang 15% attenuation? these are just the ones I saw in Ace hardware. The 12V are battery chargers, can they also be used to power the amp?
thank you very much.
-
If you're going to use the 13.8volts for the t-amp, wag mo nang subukan, its risking a burnout of the chip. But if you're a bit adventurous and want to try it anyways, make sure may heat sink yung chip mo, para makatulong sa dissipation ng heat, and make sure 1% tolerance yan. Yung 12volts na battery charger ok na yun, basta make sure at least 2amperes sya, tapos maganda ang regulation. No such thing as 15% attenuation, regulated PSU na yan, pero given the tolerances of the parts used, pag di gumamit ng 1% tolerance na resistors for voltage adjustment sa PSU, yang 13.8volts mo may +/- na 1.387 volts (assuming 10% tolerance which regulated PSU makers usually use), thus pwedeng bumaba ng 12volts pero pwede din tumaas ng 15.1 volts, and with that voltage, sure ako, less than a few seconds, putok yung amp.
-
oh ohh... :(
thanks for the tip sir D0Hbert...
-
Sir dennis, the Tripath TA2024 datasheet says the maximum rated supply voltage should not exceed 13.2 VDC. check this link http://www.tripath.com/downloads/TA2024.pdf. The more adventurous modders did increase voltage supply to 13volts, mas maganda daw tumunog compared to 12v, pero ang tolerance dapat is 1% lang. Ako nanigurado, stuck with 12volts, at least di ka kinakabahan na pumutok amp mo. I suggest you try the tweaks first, they have a much bigger impact on sound quality.
-
sirs.....ive been using Zebra regulated power supply 13.8volts 6amperes. so far ok naman siya at hindi umiinit ang t-amp ;D
-
oweidah, I also have a 13.8v power supply but I did not use...sayang pwede pala, nakatipid sana ko......thanks for the info
-
ive also tried t-amp with a big & heavy Knight 13.8v reg.powersupply of sir Handyman - used the 10amps and 7amps terminals. drove his diy fostex fe167 94db and diy Rosa floorstanding speakers ... ;D
-
Ako rin 13.8 Zebra thru lighter jack. So far hindi pa naman sumasabog, medyo mainit nga lang.
Okay ba yung stealth mode. compared sa ibang tweaks?
-
So far, yung stealth mode ang pinaka madaling gawin, may tatanggalin ka lang 2 resistors, 2 input caps sa board tatanggalin, tapos i-short yung connection nila, then i-attach mo na yung bagong 2.2uf na caps sa hilera ng saksakan ng cable.
-
DOHbert, what would be the effect on the sound of the T amp if stealth mod is done?
-
Better bass response, please read my post on 8 Feb.

stock sonic impact t-amp @ home in its new crib built by sir handyman... atop is the acoustic research tds202 sound enhancer

I bought na lang the Zebra DC Regulated 13.8V 3A in Raon this afternoon for 550 bucks. This goes for I think Php 799 in Ace hardware. The 6A goes for 850 bucks while this costs more or less 1.2K in Ace. I've been searching for the regulated 12V but to no avail, all I saw were 12V AC-DC converters and when I tested them, average Voltmeter reading was 15V! :o :o :o
Anyway, when I went to Ace and tested the Zebra 13.8V 6A, the reading was a little over 13V, maybe 13.2 to 13.3. Analog lang tester nila eh... ;D ::).
BTW, this will be my set-up for bedroom use...
Onkyo C-200 CD Player
Sony MDS-JB920 MD Deck / Sharp portable MD
Tono Pre-Amp (stock)
AR TDS202
SI T-amp (stock)

I hope kayanin yung speakers ko (88 db sensitivity) ::) ...
thanks.

@ DOHbert
May tip ka ba sa pag-alis ng dalawang resistor at sa pag-bridge? Parang mahirap eh, anliit masyado.
-
Suggest ko sir gumamit ng soldering iron na gamit ng pang repair ng cellphones, dapat talagang mapayat and matulis ;D I have a soldering and hot air station since dati nag rerepair ako cellphones. So kung wala kang ganun, and may kakilala kang nag rerepair ng cellphones, sa kanila mo nalang patanggal yung r01 and r02 ba yun, tapos ipa short mo yung c1 and c2 ata yun. Kung malakas loob mo, suggest ko kanito sa pagtanngal, use 2 soldering irons, place both tips at both ends of 1 SMD resistor, then sabay pitik or buhatin palayo ng board. Wag pwepwersahin ang pag tanggal or masisira yung contact sa board. Ingat lang and wag madaliin. :D
-
oweidah, nice box for your T amp..... mas maganda siguro kung si Charlize Theron ang nasa loob.....
-
thanx ding45...'onga charlizeT but hindi muna ni-risk retoke k dra.vikiB baka maaksidente walang pamalit. later siguro sa next t-amp. maganda rin may pang reference before & after retoke para makumpara. rite now, maganda ang synergy ng stock t-amp with ar tds202 - esp. for extended LEISURE listening- no ear fatigue whether audio or HT ;D ;D ;D
-
@ DOHbert
Salamat. I think the first option will be best for me. Thanks a lot. Now to the Bat Mobile.
Saan pala nakakabili ng Blackgates dito sa Pinas?
-
One nice thing about digital amps/t-amp is that when they distort, di sya kasing irritating as solid states, pero di din kasing swabe ng tubes pag nag distort. Ang pinakamataas na volume level before distortion is around 3 o'clock or 75% full volume setting. Yung 88db nyo sir can be easily driven by the t-amp, tapos with a tube preamp, pwede mong taasan ng konti ang gain nito to give the amp a little help.
-
Eto yata problema sa T-amp yung distortion nya. Mareremedyuhan ba to ng input tweaks?
-
Eto yata problema sa T-amp yung distortion nya. Mareremedyuhan ba to ng input tweaks?
sir maynard, accdg. to other websites' forums, tweaks do improve the s.i. t-amp. When using the stock t-amp be aware of its limitation (estimated 6watts-8ohms / 9watts-4ohms). maski anong amp. basta sinagad sa kapasidad eh nakakairita ang distortion at nakakasira pa ng tweeter ang pag nag-clip (SS amp). yun nga ibang amp. maski hindi driven hard ay nakakairita pa rin ang tunog pero itong t-amp sweeeeeet, klaro, detalyado. pang balentyms!!! ;D ;D ;D
p.s..... try "handyman's" fostex bookshelf speaker (94db) swak sa t-amp! :)
-
Actually you can barely hear it pero present sya at mid-levels. So ayon ang pinaka weakness nya I think, you cant drive your audio at full blast and brag its bit perfection.
BTW. Saan ba merong Blackgate Capacitors?

sir, depende sa listening area and preference (obviously loud & hataw) suggest u try the ff: to maximize potential of the "stock" t-amp.
1.use high sensitivity speakers - ex. klipsch RF series floorstanders 94db +available sa spectra,
parksq.mkti or fostex based diy speakers (check out fellow member "handyman" 's fostex or
living voice,wilson,vintage jbl,alteclansing,lowther etc all 100+db.....
2. you may wana pair the t-amp with acoustic research tds202 sound enhancer
check out audiokarma.org forums for user opinions/reviews on this combi
3. use a preamplifier (dennispm used tono tubes, ding45 used cambridge azur integrated, i've
used nadc320bee) or preamp./processor (yamaha avr with front preamp-out & you can use
the subwoofer out)
4. tweak the t-amp
5. if still not satisfied, use a SS amp preferably vintage.
* i dont know where blackgates caps are available but if i remember rite noong 90's may office sa west ave.QC nag-ads sa buyandsell mag. .... check out the tuberos or diy guys d2 or sa pinoyaudio or WS. i'm sure alam nila ;D

...paano na si monica?, isama mo na!? ::)
-
Ang alam ko nakahubad si Charlize.....madali nang kabitan ng mga connectors, may guide naman yan how to connect the speaker posts, etc.... Si Monica is a DAC, kaya lang satisfied na ako sa DAC ng NAD C542 ko kaya I have no intention of getting one.... BTW cant seem to connect to DITparadise

Is that the amp3 from 41hz? Yep, with the amp3 or amp6, you'll hear more details from your music compared even to a heavily modded sonic impact t-amp. Just a few minutes back, I was listening to a Jheena Lodwick's "Make it with you" from the Getting to know you album. I have 2 copies of the same song, one copied on a black cdr at 8x speed, the other on a cheapy platinum, printable top (white) which was probably burned at 40x, and with the amp6, the difference in sound due to media type or at least burn speed was pretty evident. The black cdr produced a more expansive soundstage, the guitar was playing from the right side but every pluck of the strings was resonating from right to right/center area, and the lower treble was definitely better, and overall much warmer. The platinum on the otherhand reproduced the guitar solely on the right side of the soundstage, voice was a bit thinner compared to the black cdr, and generally, sound was more "malata" and less musical. It's with these kind of revealing amps that I actually begin to appreciate such "trivial" things as burn speed and media color, problem now is which copy is more identical to the original copy ;D

Kung madami na kayong nadinig sa T-amp, dito mas madami kayong madidinig. ;)
sir jojo, basta maganda ang tunog ayos!!! baka p0 may fully dressed nyan na binebenta kayo? para ok WAF ;D

Dohbert, JojoD818
Why dont you guys assemble on your spare time, then sell these kinds of amps here in pdvd or ws. I'm
referring to the Charlize, Amp3,Amp6.... I'm sure you'll have your hands full of orders owing to the popularity of these new breed of amps......I'll be the first customer...
-
Si oweidah pala first customer.....ako second.......anyone third?
-
onga naman sirs jojod818 & d0hbert!!! (kailangan ba ng 100signatures pdvd peoples initiative??? ;D ;D ;D)
suggest you assemble & build caseing for - tweaked sonic impact t-amp, 41hz amp3 and amp6, charlize....
ding45 no matter sino una satin oks lang basta lahat happy ;D

tapos mag t-amp session gaya sa kabila diba sir jojod818?...since matumal yata sa kabila ngayon nahuhumaling sila sa bengbeng ;D
-
ding45, oweidah,
So sorry guys but I already have my hands full with projects at the moment, so many orders, so little time.
I have also been commisioned to prep for a coming amp2 project, this still falls under class d even at 2x 300w so I'll post pics here when it arrives. I was told that assembly is kinda tricky, but unlike amp3 and amp6, this one is not gonna be boring.
On the lighter side...
Charlize T = Aeon Flux = Nice butt! ;D I never thought of her as a class d amp though. ;D ;D ;D

David,
I have been using black cdr for almost 2 years now since I posted a documentary that I did somewhere using different drives and discs. It seems that the black ones are more consistent to sound like the originals.
cheers

if you guys know someone who has paypal, we can course our oders through him...just a thought
-
Pahabol lang, sa mga interesado, I will try talking to my Singaporean supplier if he can get Charlize and Monica for us, tapos padala nalang nya thru FedEx or something. Kailangan ko lang ipunin orders nyo, tapos deposit nalang yung mga interesado, tapos kung kulang yung deposit sa costing for freight, tax etc, dag dag nalang upon pickup. Paki lista lang names ng interesado. Pwede ko rin i-order yung mga kits tapos ako nalang mag bubuo, tapos charge you guys for labor. What you guys think?
-
count me in!
paging ding45? oweidah? ;D
-
Magkano ba aabutin?
-
sir d0hbert... ok ako sa charlize T kaya lang sana may casing na. post or p.m. us the mechanics sa purchase deal from diyparadise or wherever. thanx for the offer :)
-
Please give me a few days to coordinate with Yeo, para ma-estimate ko magkano aabutin landed cost ko. I'm planning on getting distributorship from Yeo for both the Amp and the NOS Dac. Thanks for the interest.
-
Count me in for the Charlize
-
magkano yung monica2?
-
you might also be interested with this DAC

the monica2 will end up cheaper than the dddac...but to what is better sounding? can't say
-
A bit of an update regarding my correspondence with Yeo, he admits they're on a backlog for both kits, the Charlize and Monica2. I'm trying to negotiate with him, if I can get the kits bare, then I'll assemble them once they arrive, so that it will be much faster than waiting for him to fulfill all pending orders. I'm initially placing an order of 20 kits for Monica2 and Charlize, he was shocked and said he can't supply that many kits as of now. I'll post an update again for any further developments. So far, things aren't looking too rosey. :-\
-
sir d0hbert, thanx for d update. it seems in demand sila charlize at monica. international pantasya ;D
-
may price na ba for unassembled kit ng monica2?
-
Just an update. Yeo is not willing to give us any discount for the group buy, so selling price is still the same as that listed online. For the monica2, a completely assembled kit is $125, plus freight of $20 (just to be sure), then local tax of 12% of total price, so roughly $196 or around P10,000. For the Charlize, its $90 for the kit, $20 for freight and tax, so it will be around $123 or P6,400. If you're still ok with these prices, please list your name, and the kit/kits you're interested in, so I can consolidate all the orders, and have Yeo commit to us a delivery date. Thanks a lot.
-
pm sent
-
sir d0hbert....ygpm.
-
Another update, Yeo just emailed back, still can't commit on a delivery date for the kits because: 1) they don't allow shipment of knocked down units, tapos tayo nalang magbuo para madali, ayaw daw nila ng sakit ng ulo pag di natin mapatakbo, which is understandable naman, 2) they have a big big backlog, so matatagalan pa malamang orders natin. So sabi ko, instead of 20 units each, gawin nalang 10 charlizes and 5 monica2, tapos humingi na ako ng commitment on a date for delivery, wait nalang pag nag-email pabalik. Medyo mahirap syang kausapin, mabait naman, pero dapat 2x nag sesend ng email para sagutin, baka makulitan na sa akin ::)
-
DOHbert, count me in for an assembled/tested Charlize from Yeo.

ako hindi pa ;D eto yata website nya ->
http://www.audioreplay.net/tc754eb.html
mukhang as the front panel label says..simple phono preamp (so you can attach a TT to the t-amp via the tc754) and three(3) inputs for line level sources (cd tape tuner tv etc)..whether it enhances or degrades the t-amp, ewan.
i think meron similar products ang avesco sa roosevelt ave. /avenida / cubao...QED brand pero 220vac not 12vdc ;D

I need to finalize all orders for the Charlize and Monica2. According to Yeo, backlog for Monica2 is 1 week, mukhang kaya na ipadala yung Charlize. I need one final headcount for those interested in the kits, after which, I'll PM you my bank account number for the amount to be deposited, then I'll send the money to Yeo via T/T. Thanks.
-
Ok, Yeo's giving us 5 Charlize, which is already assembled. So if I can have your orders and money deposited within the week, much better. So I can do the fund transfer on Monday, then have the kits either on Thursday or Friday. One of the 5 is mine by the way. ;D Adriane wants 2, ding wants 1, so that leaves 1 more kit up for grabs.

;D Adriane wants 2
WOW :o si sir hans adriane ba yan? bi-amp charlizeT?! ganda nyan! ;D

pass muna ako :) just for the sake of anyone curious why two? i plan to use an amp for each speaker using 1 channel each so parang monoblock ang dating. Given the relatively low cost I can try this experiment as the amps as you know are bridged, using just one channel is safe and should have less cross-talk interference hence more clear....assuming your speakers are sensitive and revealing enough :) but alas i would have to order at a later time...other priorities have to be attended to first :)
-
Any recommended small - tiny speaker for the T amp with 90+ sensitivity, with decent bass if possible? I just asked a relative to get 2 t amps for me in the U.S.
I have a 89 sensitivity bookshelf but its big & bulky for our small bedroom. I was hoping to have small satellite type speaker to complement my LCD tv.
TIA
-
Has any tried to repair a T-Amp? After 2 months of use, my left channel isn't working anymore.
-
Try measureing DC Offset at the output/speaker post, both left and right should have some DC voltage in the millivolts range. Next, check for 2.5v from between the input caps since the board is biased at 2.5v. If the voltages are not ok, check continuity between 1) PCB output and speaker binding post 2) PCB and amp input. Refer to TA2024 notes to see which components go to the input and output.

Hello shotgun. Is it possible that voltage is too high from your adapter? Was your amp running very hot?
-
If one of the channels is working, nagkaroon ng short somewhere sa side na nasira, pag over voltage kasi, mamamatay yung chip, so both channels dapat sira.
-
d ba may over-current at over temperature protection ang tripath chip ta2024?
-
baka walang over voltage protection? ::)

baka walang over voltage protection? ::)
ayun tumbok mo sir jojod818! paano na lang kung wala ka dito? as usual hindi lang very informative and educational ang mga posts mo.
sana may separate and dedicated thread kayo ni sir 2ny para sa aming mga walang alam sa electronics at technical stuff :)
just wondering...as per this post http://pinoydvd.com/board/index.php?topic=48430.0
sir shotgun sold the t-amp to lordfoo. eh ok naman daw sabi ni lordfoo. ano kaya reason, after two months used hindi na gumana isang channel t-amp kay shotgun pero ok k lordfoo? (baka mas ok ang power supply ginamit ni lordfoo?)

Hmmm... In that ad, shotgun said:
"I'll throw in a 1000mAmpere Multi-Volt AC to DC adapter to the package."
So my guess is, lordfoo is using the same power supply?
By the way, is it ok to use this kind of power supply with this amp?
-
Merong over current and overtemperature protection ang mga tripath chips, wala lang over voltage protection. Mahirap sabihin kung anong nangyari until na trouble shoot. Easiest way is do the DC offset check parin to see if buhay yung channel. Di dapat naman baklasin yung amp to do the test, multi tester lang in DC millivolts setting tapos dikit sa speaker output + and - nang side na pinagdududahan. Sayang din para sa seller and swerte din si LordFoo

in fairness to guys who uses "off the shelf" power supplies, it is the lifeblood of your t-amp, try not to skimp on it just to save a few hundred pesos. ::) of those psu that I built, so far wala pa naman fried t-amp. ;D ;D ;D ;D
in times of war, it is an advantage to know your enemy - in these case, know your chips! hindi naman siguro tama yun kabit dito kabit dun or upgrade this and upgrade that - and most of all try to figure it out yourself, instead of just reading upgrade reviews. ;D ;D ;D ;D
btw, congrats LorFoo! ;)

At 4ohms, RMS power of the amp is 15w (assuming you're comfortable pushing the amp at 10% distortion), that's 30w for both channels, then given the efficiency of the amp, around 80%, that should be be around 36watts maximum, for 12volts input, around 3 amperes should be sufficient. For 8ohm operation, it can be lower, mga 1.5ampere is enough.
Some say its better to have higher amperage for the amp, but then again, there's an issue of benefit gained with anything higher than 3 amperes, mathematically, the load requirement of the amp, used with 4ohms speakers, with 12volts input, and maximum output of 15w (10% distortion) is just 3 ampere, tapos some guy from tripath said 1.5amperes is more than enough for the sonic impact. If you increase voltage from 12volts to 13volts (the maximum as per tripath datasheet), the ampere requirement is reduced to 2.65.
So kanya-kanya yan, but I suggest a quiet PSU section tapos well regulated. Pag bumili kayo ng mga regulated PSU from Raon or Ace Hardware, baklasin nyo, look at the innards, check particularly the filter caps and the regulator used, you can get a general idea of the quality of the PSU. Hope this helps
-
mga sir,
sorry medyo OT to kasi ps ang question ko. but i will be using this for a t-amp.
i have an old cannon brand converter/charger with 6v/12v dc output selection. i checked the voltage when switched to 6v = 6.5 but when switched to 12v, the actual output (using a digital voltmeter) reads 15vdc. nakakatakot tong converter na to kasi ang taas na ng output. this converter is 6 amprere, medyo malaki ang box/casing nito.
i plan to modify it by installing a proper 12v regulator. is there a regulator kit (specifically for a 6 ampere rig) for sale in the electronic shop? i do diy sometimes but i'm afraid to mess things up and fry anything hooked up to it, that is why i prefer to buy the assembled regulator and just plug and play.
please shed me some light where to acquire this regulator kit.
thanks in advance.
-
Actually sir, with around 16v output, I'm assuming ang AC output ng trafo sa secondary is 12vAC, for a cheap and quick fix, buy a big 16,000uf-20,000uf 35v cap, attach this after the rectifier diodes, ingatan lang ang polarity. After the big filter cap, attach a nice voltage regulator, use lm338 or lt1084, any of those 2 will be nice, positive line from the big filter cap to the (in) leg of the regulator, then from (out) to (adj) one 100ohm 1/4w 1% metallized resistor, from (adj) to ground one 860ohm or 850 ohm 1% 1/4w metallized resistor, after the regulator, place one small 2200uf cap. Output should be a well regulated 12v ;D
-
Some of these regs needs a Vin-Vout=3V minimum to maintain line regulation, once your 15V input sags under load you'll loose regulation and output won't be a well regulated 12V.
-
(http://us.st11.yimg.com/store1.yimg.com/I/extremepcgear_1888_733628)
How about using this as a casing? OT it might also work for an lm1875 chipamp :)
-
Please help! My amp suddenly stopped working. While handling, I noticed something is shaking inside. So I decided to open it. Only to find out that the Tripath chip was loose.
Help me bring it back in order.
Thanks!
-
How did that happen, if you're talking about the sonic impact t-amp, that thing is surface mounted, with around 40 or so legs soldered to the board, it won't just get detached easily. You can take the amp to me, let me take a look at it. PM me.

excerpts from tnt-audio:
T-Amp mods
Ciao Lucio,
here are my T-Amp modifications.
* Metal cabinet: front and back silver-metallic, rest is a kind of "hammered" look
* 12V / 3A power supply pack with toroidal transformer
* gold plated female cinch connectors
* gold plated speaker terminals
* cable connection incl. on/off switch
* high quality Alps potentiometer (from the blue series, RK27112)
* LED on front fascia
Normally a non-tweaked T-Amp has a weakness in the bass range below 100Hz. This T-Amp is modified for this and has an absolutly straight frequency response from 16 Hz - 26 KHz within ± 0,5 dB.
Total cost for materials: approx. 150 Euro (toroidal transformer, cabinet, connectors and binding posts, ALPS volume Pot, capacitors).
-
Hi Oweidah!
Had my t-amp reboxed by a technician, using said gold speaker/rca posts but retaining the original volume pot. Also was able to buy from Deeco a 12v/12a power supply. Another tweak i made that i thought didn't matter was to replace the stock power cord of the PS and T-amp with the TNT designed one. This latest tweak really brought out the bass to another level.
Hanep the details this amp can dig out, can hear the noise of the amperex tape reeling in the background on a guitar solo CD (forgot the title) and even the cough of somebody in the background on the music "Vincent" (Best Audiophile 3)...very revealing.
Hope the others are enjoying the amp as well...cheers ;)
-
hi tonyc,
here's my stock t-amp re-cased by sir "handyman" with rca plugs/binding posts @ the back panel with a.r. tds202 sound enhancer (atop). stock pa lang, no internal mods. balak ko sana later (budget permits) acquire another sonic impact and do some mods (sana nga yung gaya sa tnt-audio picture posted above kung meron kaya gumawa). but as is the s.i./tds combo sings!!! or maybe the charlize ;D gamit ko zebra regulated power supply 13.8v/6amps.

Hi-fi technology turns to smaller, cheaper chip-based operation
1/3/2006 8:01:00 AM
Source : Business World
DAVAO CITY -- Within five years, the high-fidelity audio industry would be shifting to smaller, lighter, and inexpensive electronics, specifically in the case of stereo and multi-channel amplifiers.
Electronic chips developed in recent years that are capable of producing audiophile-grade sound would eventually put aside high-priced amplifiers into vintage category.
This breakthrough has taken root among electronic do-it-yourself enthusiasts and, in a couple of years, would likely be applied in consumer electronics produced locally.
Since early last year, audiophiles have tested and modified their sonic impact tripath amplifiers, the first commercially available audiophile-grade chip-based hi-fi gear brought in mostly through online sources.
The first generation sonic impact T-amp is small, weighs just a few grams without the batteries, with cheap plastic casing and sold for as low as $20 from e-cost, a United States online retail site.
My two units, which arrived in Davao sometime in April, were bought through Amazon.com and cost an average of P2,500 apiece including forwarding charges.
A good number of Manila-based audio enthusiasts, however, got their units earlier, with the majority applying modifications such as changing the capacitors, improving the connectors, and installing a new potentiometer, or volume control knob in layman’s terms.
Many went for better-looking amplifier housing -- handsomely sculpted wood or transparent glass -- which do not result in sonic improvement but certainly attracts both enthusiasts and non-enthusiasts alike.
The sonic impact T-amp is rated at an average output of eight watts per channel at eight ohms, or 15 watts per channel at four ohms, an output at par with many tube amplifiers.
That rating is adequate for normal use and could even meet the demands of dynamic chamber music at loud volume in a typical room of, say, 20 square meters, provided efficient speakers are used.
Efficient reproducers mean those rated at 90 decibels at one meter listening distance and at one-watt amplifier output.
Since the amplifier’s usual electronic components are shrunk into a small chip -- the Tripath TA2024 -- less than one square inch in size, heat sinks are no longer needed.
Efficiency also improves with the signal travelling a shorter path compared with traditional amplifiers. With low output and a new amplifier topology, power is optimized translated to lower consumption without sacrificing sonic quality.
The T-amp needs a separate power supply, though, since it was originally aimed at the mobile audio market.
It operates using eight penlight batteries, which could last several hours of continuous playing depending on preferred loudness level.
Without the batteries, it needs a regulated 12-volt power supply converter to be plugged into the standard 240-volt power line.
The converter rating should preferably be at three amperes to maximize the amplifier’s rated output.
Such preference is derived using the general formula of voltage multiplied by amperage is equal to output in watts, in this case 36 watts or slightly over the 30 watts total maximum output of the unit.
Initially, local audiophiles claimed it is best to hook the T-amp to a 12-volt lead acid battery to perform best, but in my experience, using a 12-volt regulated converter does not result in sonic degradation.
This is confirmed by latest observation among foreign audiophiles as per posts in audio discussion fora. Since I have two units, one has a regulated 12-volt supply and the other a 13.6-volt converter, which some listeners in the US said results in better low frequency response.
On the first day I received my two T-amps, I tested one unit against a 30-kilogram (240 watts per channel at 4 ohms) Sansui AU-XII amplifier, originally priced at ¥275,000 in 1983.
I arranged them to appear as if I was comparing the Sansui with another amplifier, an Accuphase E-302 (180 watts per channel at four ohms) using similar sounding speakers: ElectroVoice Interface A and Denon SC-104.
My two children who came in from school had common observation: there was no difference at all when the volume of the two units were at room level.
Increasing the volume several notches higher, the children said the Sansui was slightly better sounding, not knowing it was actually a small 15-watt T-class amplifier not the Accuphase, which was compared side by side with the Sansui.
My wife who came in later said even at high volume, the sound quality from the two amplifiers was the same. Later, they were surprised to find the one pitted against the Sansui was a small amplifier that looks more like a child’s toy.
In the succeeding days, friends who would visit me were also amazed by the T-amp’s performance considering they were used to hearing only monster amplifiers.
In my opinion, the sonic impact T-amp’s sound is significantly superior compared with entry- to mid-level amplifiers, whether new production or vintage types.
Its sonic character could be described as in between the solid state’s fast, clinical response and the tube’s sweet and gradual sonic decay.
While it puts out clean and pleasing sound, the drawback is in reproducing the dynamics required by some classical and show-off pieces at loud volume.
A listener into rock, jazz or the usual popular music categories would be happy with this amplifier, especially when hooked to mega-loud performers from Klipsch, Altec Lansing, JBL, ElectroVoice, or Cerwin Vega.
By this year, higher-powered amplifiers using newer Tripath chips would likely achieve what the monster vintage amplifiers -- those with continuous outputs of at least 200 watts per channel -- could do.
The Tripath chip’s ascent as an audiophile-grade amplifier component started last year when a San Diego, California-firm sonic impact technologies marketed its Tripath-driven amplifiers aimed at the mp3 player market, specifically users of Apple iPods.
Some early buyers accidentally hooked their small plastic toys to larger speakers and the rest is sheer serendipity.
Last January, TNT Audio , Europe’s leading audiophile Website, reviewed sonic impact T-amp and found its performance comparable with solid state and tube-based amplifiers costing thousands of dollars. That review resulted in a sudden demand surge causing a temporary supply shortage.
Hundreds of local audio enthusiasts were among the first wave of T-amp buyers early last year with some enterprising groups accepting advanced orders in Manila at P3,500 per unit.
A few realized they could buy cheaper and went straight to online distributors.
That costs less than P2,500 per unit, coursed through a local forwarder, with delivery time from one to two weeks.
Acquiring the original sonic impact T-amp at less than $30 nowadays, however, could be difficult after the company introduced recently a revised version of the original amplifier now priced at $139 P7,367 at $1:P53) per unit.
Except for a better-looking case and improved connectors, all other specifications of the new model are the same as the old unit.
Dr. Adya Tripathi, the Indo-American engineer behind the Tripath chips noted as far back as 2003 that chip-based amplifier technology would dominate the consumer electronics subsector before the end of this decade.
Mr. Tripathi’s company, Tripath Technologies, Inc. based in San Jose, California, started operating in the mid-1990s.
The latest feedback indicates the price of Tripath chips has fallen from over $10 (P530) each for a low-powered amp a couple of years back, to less than $5 (P265) each now for high-powered amps.
The latest of the company’s amplifier chips puts out 400 watts output and designed primarily for subwoofer application.

mga sir,
i will soon be getting a charlize t-amp (from sir dohbert) and prep'ing things up to complete this tiny jewel.
my queries are:
1. what pot resistance would i use, a 50 or 100 ohm?
2. where to get an ALP pot and how much?
3. what wire is best (or better) to use for the connections (eg. speaker, input rca and power)?
4. where can i find an OFF-ON-ON power switch for the soft start config and what is this switch called?
5. what is the max safe regulated power supply voltage to power the charlize?
hope to hear from y'all soon. i am very excited to build my first semi-DIY amp.
cheers ;)
-
1) Pot resistance, use 50kohm
2) you can get blue alps from silver strings
3) for wiring, I'll be using belden patch cable, 8762 ata yung model number. Or you can try cat5e, teflon covered for wiring
4) no off-on-on switch, but you can use a 3-step rotary switch, with the resistor between the 2nd and 3rd step
5) max voltage according to yeo is 14v
-
I've been wanting to ask this. Why 50K for the pot? Why not lower?
Thanks.
-
sir ilang watts po ba ito? channels? puede po kaya ito gamitin as power amp to be paired to my yamaha 750? i am entertaining thoughts of using yammy's pre out with a dedicated power amp, can this be the solution i wanted?
-
hi agmjr... eto website t-amp http://www.si-5.com/info/homePage.html at eto thread dito sa pinoy dvd http://pinoydvd.com/board/index.php?topic=47023.120 ... im now using (and i highly recommend) two (2) t-amps biamped (to biwireable speakers) with AR tds sound enhancer and yamaha avr as preamp/processor. ang ganda kesa sa single t-amp! wider soundstage and a bit better tighter bass (though not as deep as desired pa rin) stock pa lang na t-amp yan. the key is a good power supply ;D

thanks po

Regarding the 50k pot question, as per Sonic Impact, it already has a input 10k impedance, so depending on the value of the pot used, it will change the input impedance of the amp. For example using a 50k pot will give rise to a input impedance of 8.33 for the SI, if 10k is used, input impedance is 5ohms. And generally, input and output impedance (of the preamp or source, for example) matching is ideal for maximum power transfer, for if you have mismatched impedances, then you get inefficiency in the transfer of power, more power is lost. However, if you want the largest voltage signal at the input of the SI, then its input impedance must be much larger than the output impedance of the preamp or the source before it. Thus, if you want to drive the amp easier, it's better to use a 50k pot than the smaller 10k pot. ;)
-
anu yun pot?
-
Yung nirorolyo tapos sinisindi parang yosi, tapos parang nasa langit ka na ... :o oops, ibang pot pala yun, by pot we meant volume pot sir.
-
Bro, Who sells this this t-amps or where can i buy this modified t-amps?
-
dohbert,
mali ka naman eh, yun pot yan yun ginagamit sa kitchen pag nagluluto! ;D
serious...
pot is short for potentiometer. a variable resistor popularly used for audio volume control. ;)
-
sir agmjr, using your yamaha avr as preamp/processor and the t-amp as power amplifer for the front channel is, imho, the perfect compromise for a setup na- hindi lang pang HT, pang-audio pa!
instead of having the ideal separate audio and ht setup, merged audio/ht setup na.
"timplahin" mo na lang x'over cutoff ng subwoofer para saluhin pagkukulang t-amp sa lower bass (100hz and below).... ;D

ano magandang pot for t-amp? san pede bumili? pde ba pumili ng knob?
-
Regarding the 50k pot question, as per Sonic Impact, it already has a input 10k impedance, so depending on the value of the pot used, it will change the input impedance of the amp. For example using a 50k pot will give rise to a input impedance of 8.33 for the SI, if 10k is used, input impedance is 5ohms. And generally, input and output impedance (of the preamp or source, for example) matching is ideal for maximum power transfer, for if you have mismatched impedances, then you get inefficiency in the transfer of power, more power is lost. However, if you want the largest voltage signal at the input of the SI, then its input impedance must be much larger than the output impedance of the preamp or the source before it. Thus, if you want to drive the amp easier, it's better to use a 50k pot than the smaller 10k pot. ;)
I see. I was thinking of the pot as a "source" too.
-
with the pot dohbert was implying initially..we'll definitely be jammin' 8)
-
I see. I was thinking of the pot as a "source" too.
Follow up (not debating, just asking): If the 1/R3=1/R1+1/R2 applies w/ the pot and input impedance of the amp, how can a 300-ohm ouput from a source drive the resulting 8.33 or 5 ohm input impedance?
---------------
Sorry. 8.33K and 5K pala. Ok na. Thanks, DOHbert.

I was able to borrow a T amp from a pdvd member and used it with a tube pre amp.
Wow, ang galing nga nito! I was skeptical of its performance but it really awed me what this little thing can do. Ang linis ng tunog!
Only problem was, I tried to play movies with this and kulang sa Bass. SS power amp pa rin.
I plan to buy 2 for bi amping soon. ;D. At least now I saved a lot instead of setting aside a bigger budget for a tube power amp.
-
sir matzter pag ht i use the subwoofer for LF bass duty ;D pero yung sonic impact t-amp power for fronts speakers - WOW! (limitetd bass nga lang hindi as deep tight controlled as those by muscular ss power amps pero kung ok subs mo ayos na!...i wont trade the t-amp sound quality for AVR ) ;D ;D ;D
-
sirs...OT....baka may alam kayo iba pa bang # ang daichi maliban sa 635-3111...tanong sana ko sa euros8 pero di makapasok....lagi busy! ::)
-
I was informed about this but I called Daiichi and they dont have any stock left :'(. Pinapakyaw daw by the hundreds ng ibang dealers. >:(
puede po kaya ito gamitin as power amp to be paired to my yamaha 750?
Pag power amp for music pwede, but for HT, kulang ang bass nya. I just tried it out last night with a borrowed T amp from a pdvd member.
-
Maganda nga, but I am using it for my bedroom setup only, so no AVR or Subs there and I only use the spare equipments (spare SS amp, spare bookshelf, IC, wires) I had in storage. :D. Siguro my option for now is to switch to SS for movies, My SS amp plus bookshelf is good enough kasi for watching movies. Eh yung bedroom setup is for watching concerts and P**ted dvds lang naman. ;D
Pero for vocals, ok na ok na ako sa kanya. Pag other music, sa main HT room na lang ako.
Galing, this T amp suits my needs, and most importantly, my budget too!
-
its sad if that happens, the product is offerred at a good price but we have greedy people capitalizing >:(

HTH.

here's what I did to compensate my bass shy giant-killer. My Sony CDP has fixed and variable line out. I connected the variable out to my H/K integrated driving wharfe 8.2s and the fixed out to Tono Pre - TDS202 - T - Amp driving b&w 303s. For vocal music, the latter can do justice but for other types of music my H/K-wharfe compensates for the needed ooommph.
Just me. ;D
Thanks.

Naku, dont buy this t-amp. Not good. Namimili ng speakers at less than 15 watts lang. Ang sound eh mediocre lang. Overhyped reviews. ;)
Pag nakabili na ako, saka nalang kayo bumili! :) :)
Sana may limit ang dai-ichi sa pag bili, max of 2 units lang. hehe
Oweidah, please send PM about your t-amp experiment results. thanks.

easy!!! 1x1...biamp muna....pag nabihisan na (re-boxed/new casing) tsaka subok ala "monoblocks".
eh ikaw, ano user review mo sa 1) t-amp / 12sn7 preamp combo... 2) t-amp / nad c320 as preamp combo....3) nad c320 main amp / 12sn7 preamp combo.... 4) biamped t-amp (hf) +nad c320 (lf) / 12sn7 preamp combo?... ;D
-
Pwede ba ang Bi amp by using T amp for HF and SS amp for LF? Has anyone tried this? TIA
-
sir matzter...split mo preamp signal using y-adaptor. one ic pair goes to the t-amp, the other goes to the ss amp. now connect the t-amp speaker terminals to the HF of your biwireable speaker. connect the ss amp speaker terminals to the LF.... i think markmlists is trying this with his t-amp/nad c320 (main-in) and 12sn7tube preamp :)

sir dennispm, uy naka-tds202 ka na pala. review naman ng pair nya with tono tube pre. kasi sandaling pakikinig kagabi, biamped t-amp+tds+tube preamp eh parang mas ok pag naka-bypass (off) ang tds pero pag yamaha avr as preamp/processor ang gamit ko, sakto match with tds202. someone said na para daw "tube buffer" ang effect ng acoustic research tds202. honestly di ko alam kung ano ang tube buffer eh hindi naman ako "tubero". yung lang pansin ko ;D
-
Tried using CA Azur 540A to drive the LF on the Diamond 9.1 and the T-amp on the tweeters... didn't like the sound....dismantled the setup after listening for 10 mins...and went back to the Azur pre/T-amp power amp setup....

thanks bumblebee. is there any other brands that is a common find in an elec shop? dunno if alps is sold in cebu. just checking my options though. i wanted to test a charlize once i get it. can i use a locally sold pot just to test the amp? i will contact silver strings and hopefully they will accept out of town sales.
-
silver strings has only 100k ohm ALPs pot available. pwede kaya to in replace of 50k? what will be the effect with the higher valued pot?

sirs, pwede din ba i-tweak t-amp to get rid of the volume potentiometer? bale on/off power switch na lang. i'm using the t-amp as power amp, naka-set full-volume; and the volume control of the yammy avr functioning as preamp/processor drives the t-amp....

Sir, please observe polarity ha, lalo na dyan sa nakalawit na wiring. For the soft-start on, use a 3-step selector switch. DC in sa input ng selector, sa 2nd and 3rd position nandun yung 270ohm 1/2 watt resistor. Ok na yan. Btw, you'll be surprise how much an improvement this kit is over the SI. Malaking malaki diperensya. Walang laban nga raw sabi ni Eposman. :D
-

yup, depende sa gain na gusto mo hehe ;D
just got two units of the t-amp so i can get my feet wet in tweaking these kinds of amps. I am powering the two with a 12v smps i got from alexan. sounds good on my newly made open baffle speakers. i am playing vocals and lite jazz and the mids sound pretty good...will just do the stealth mod before i try out the charlize or amp6 8)

thanks dohbert. wala pala tong instruction manual na kasama? print ko nalang ang mga instruction dun sa diyparadise para masiguro ang polarity.
tinititigan ko pa to sa ngayon kasi di pa naregulate ang psu ko ;D order pa din ako ng 100k alps pot sa silver strings. pwede daw ang 100k sabi ni yeo. nagpabili din ako ng SI amp sa pinsan ko na uuwi ngayon end of march. binili nya online at $39 including tax and shipping sa target. parehas lang pala ang presyo dun vs sa dai-ichi.
rotary switch ba yung 3-step selector? subukan ko sana yung suggestion mo sa diyaudio na gamit ng dalawang switch in series to make an OFF-ON-ON config para sa soft start.
-
I've read somewhere dapat same gain yung 2 amp.
bumblebee, dont know, havent tried it but simple solution- kung may existing power amp na ang t-amp user, try it (ss amp/t-amp combination in a "bi-amped" config). kung match, well and good, kung hindi eh di konting pagod lang naman, connect and disconnect... Kung wala naman, eh dalhin yung t-amp sa kilala o sa pagbibilhan para mai-audition. very portable naman t-amp. :)

setup :
two (2) units stock sonic impact t-amp-"bi-amped" (front channel) ;
acoustic research tds202 sound enhancer - (linked between t-amps and yammy avr) ;
yamaha avr - used as preamp/ processor (front channel preamp out);
sources - pioneer dvd player; nad c520 & onkyo cdps dx3500 (tnx rico!); nad 414 am/fm tuner;
b&w602 series 2 (fronts) ;
wharfedale diamond 9.1 (used as center speakers on dvd movies)
no surrounds (small listening area)
MS subwoofer (used for dvd movies only)
power supply used - zebra regulated power supply 13.8v / 6amps for both t-amps
***
listened to fm stereo and played cds,concert dvds and dvd movies - BLEW ME AWAY! :o :o :o
level of clarity and detailed presentation, wide soundstage. bass is decent.
most important is its very easy on the ear, no listening fatigue.
to hear is to believe ;D
Appreciate to hear reviews from the other SI t-amp users.
Ano sa tingin nyo, is it just hype or is the 2k SI the real deal?
tnx :)
-
Sir, Can i connect my T-amp with my tube amp?
(http://)(http://)
sir, did u mean tube power amp? or tube integrated amp?..or perhaps tube preamp?
if you meant t-amp connected directly to a tube power amp or tube integrated amp with no preamp out, no, i dont think so.
if you meant t-amp connected to the preamp-out of a tube integrated amp (assuming it has this feature), yes.
if you meant t-amp connected to a tube preamp, yes. ;D

Hi oweidah.
I believe having the same gain means same amount of amplification for both HF/LF in a biamp config given a volume setting.
OT:
I was thinking, given the type of loudspeakers we use, we are just biwiring(?) What happen if we feed different amounts of power to the HF/LF?
-

bro, gusto nya nakabypass yung volume pot at naka set sa full. in that case kung anung value ng pot yun ang gamitin nya na resistor to use the external preamp.
btw, anung gain ba ang dapat gamitin para magamit yung external preamp?

same question here.
if i will be using the charlize as a power amp, will i connect the pre-amp output straight to the RCA "in" of the amp (charlize) without putting a resistor in replace of the supposed recommended 50k pot's resistance value? from the diagram i've seen, the pot's connection is from the rca IN. so what will be the effect if no resistor is attached, will it be at full volume/gain?

bumblebee,
powering your HF/LF with different amounts of power will only alter it's balance, but no book in the world says anything about it being wrong. in some cases it has been accepted since HF drivers are much much more sensitive than LF drivers and the latter requiring more power due to shifting impedances while the coil/cone is moving.
try it and maybe you'll like it bro.
cheers
-
don't worry with the resistor bro, you can still used the amp and have it connected with external preamp even without the resistor. what i mean is, you can use the resistor in replacement of the 50k pot if you plan to set the volume pot to max and adjust the volume on external preamp.

thanks 7even. another newbie question na naman.
when using a pre-amp, will the pre-amp functions as a mere potentiometer/inputs only? does the pre-amp adds something to the output of the power amp (t-amp)?
-
the potentiometer will attenuate the input signal coming from the source (i.e. cdp, tuner, etc.)
when using a pre-amp, will the pre-amp functions as a mere potentiometer/inputs only?
yes, if the output of the source is not enough, active preamp will compensate and drive the signal to the amplifier.
does the pre-amp adds something to the output of the power amp (t-amp)?
-
oweidah,
Sorry, kung iba yung dating. I was really just asking. And anybody can answer.
bumblebee...im not offended. just wana clear the air. im not inclined to the tech side of this hobby esp amp/preamp matching- input sensitivity, input/output impedance,etc...kaya kung wala din ako macocontribute eh iwas pusoy na lang, ill leave it to you guys.
peace....
-
changed the output cap to 0.22uf solens to match it to 8 ohm speakers, next step before recasing is changing the input cap. 8) i also changed the electrolytic to 470 uf, which i had lying around, un lang ang kasya e hehe :)

for the charlize users. just sharing yeo's e-mail regarding the on/off toggle switch.
hi ruel
> attached is a pic of charlize taken from
your website. i have noticed a connection from the
board, near the J4 jumper to the on/off switch. can
you please tell me what is this for?
the ta2020 chip is supposed to have a mute function. this switch is
supposed to work on this mute function.
unfortunately it didn't. so went to power supply soft start instead.
> also, have
difficulty finding a 3-way selector switch for the
soft start. may i know what is the name/type of switch
you are using? the common finds in my place are only
the spst, dpdt's and the likes. there is also a rotary
selector i was thinking but i prefer to use a toggle
switch for the power. with the spdt switch, i don't
think that i can use it with the soft start
configuration. can 2 spst switch be hooked up in
series to replace a 3-way selector?
spst can definitely be used. wire this way.
pins 1-2.
solder 240-270ohm resistor between pins 1 and 2.
solder 12vdc supply to pin 1.
solder supply wire to charlize (white) to pin 2.
when you hook up power, due to this resistor, charlize will see less
than 8v. it hasn't turned "on" yet.
when you turn on this switch, the resistor is bypassed so it will see
12v now.
this is how i wire mine!
yeo

Sirs, Can anyone help. I got a T-amp and i want it to connect on my AMX tube amp but i dont know how to do it. Can anyone help.
Here's my number 09159298477
Thanks!

this will be my t-amp's new home
chassis 12" x 8" x 3" (w*d*h) & parts available @ raon.
aluminum front and back panel/ metal top, bottom & sides.
Sir, How much is the cost of the total make over? Parang maganda ang project mo sir!
-
tried my charlize using a 15A, 13.8vdc regulated psu. the amp was hooked up (without a pot) to a philips cd player and a pair of sony bookshelfs. my cd player has a built in volume control kaya via remote na ngayon ang pagpihit ko sa volume.
swabe talaga ang tunog, i can hear lots of details even using a so-so speaker (6 ohm). totoo talaga na ang charlize ay hindi bass shy. may bayo talaga sya kahit stock pa. been running now for 3 hours straight and going. iiwanan ko to na naka ON para aabot kaagad sa 50hrs break-in period. luke warm lang ang init ng tripath chip.
tanong lang, check ko ang voltage output ng psu ko. 13.7~13.9vdc stable sya without load. pero once connected na ang charlize and running, the voltage goes up to 14.3vdc. bakit ganito?
-
sir, How much is the cost of the total make over? Parang maganda ang project mo sir!
sir, chassis is 450pesos. binding posts (like those that wharfedale used for its diamond9.x series)= 65pesos (may tawad pa..pag matamis ang ngiti mo sa may-ari) and rca sockets= 35pesos, LED= 10,20, or 30 pesos depende sa lakel; switch = 15 to 25pesos. all available sa roan shops - smg, eleshop alexan, golden mars, oriental, newport or richland.
kung sa regulated power supply naman- sa andelnes, raon near ongpin- 13.8v/6a= 850pesos.
meron nga case hindi naman ako diy/marunong mag-tweak, so magpapatulong ako sa may ginintuang kapuso na expert. ;D
-
oweidah, sa laki ng case na yan kasya 2 t-amp and ps sa loob 8). kung me drill ka sa bahay or me kilala ka na pwedeng magbutas, medyo madali na. here's a sample diagram you can follow, if you plan to change the input caps, this called the "stealth mod" c/o audio1st of diyaudio.com.

John,
If you conduct a technical EB for all interested in tweaking T-amps (with you as a lecturer), I attend. If you agree, lets find a volunteer house, Volunteer garage. :) Kahit sa ilalim ng puno, pag ikaw nag hold, sama pa rin ako.
Kindly consider.

I saw a 12v 75w 6amp power supply at handyman for P550.00. Premier brand. I still havent tried it though.
-
Tanong ko lang po kung puwede gumamit na lang ng X2/Y2 caps instead of Auricap. And ano iyung mga effect - subjective and objective observation?
-
Gnew, medyo dangerous na yung 14.3 volts, although sa specs pwede syang gamitan ng 14.6v. Di dapat ganun, pag nagkaroon ng load, pag di stable, generally, bumababa dapat yung voltage pag sinukat. I suggest you get a good regulator instead. Sayang yung amp kung masunog. Thanks

nagtataka nga ako. nakakabit palagi ang digital multimeter ko sa psu output for monitoring. check ko rin ang mains, 245vac pero kahit mataas sya di dapat tataas ang dc out kasi may regulator naman. stable naman to pag walang load. complicated pa nga ang regulation nitong psu, aside from a pcb na may 20-pin IC pa meron ding 3 power transistor yung bakal na type. matagal na naming ginagamit to sa vhf radio.
dohbert, gaano kainit ang tripath chip ng charlize mo? yung sakin medyo mainit na after almost 4 hours of straight playing. off ko na ang amp ko sa ngayon dahil natatakot ako baka masira.
eto pala pic ng psu na ginamit ko. are you familiar with this brand?

Mga sirs,
Check niyo max load condition ng PSU. Then check for the specified regulation (didn't include ripple voltage because you need an oscilloscope which many of us don't hv). To check regulation you need a loading matrix:
eg A PSU with the ff: specs
AC line voltage: 100 - 265Vac
Output: 12Vdc (+/-5%) -> 11.4 to 12.6V
Load: 100mA - 5A
so,
nom low line = 110 and nom max line = 220
min load = 0.1A and max load = 5A
Vout = 12V output voltage
nom low line, min load condition, Vout = ________
nom max line, min load condition, Vout = ________
nom low line, max load condition, Vout = ________
nom max line, max load condition, Vout = ________
The measured Vout should be within the specified regulation limits.
Problem now is how to load the PSU with the required min and max load. One solution is to build a resistive load (use Ohms law) or, a more expensive one -> buy an electronic load or get an appliance which has max input current = max load of PSU. Just make sure that the appliance has DC input which is the same as PSU output voltage.

When feeding the charlize with 12v, you don't need a heatsink. Once you feed it 13.6-14.6 volts, kailangan na ng heatsink yan. May isang SI owner dito na nakaproblema, bumaklas yung SMD na 2024 chip from the board, suspect ko mataas ang voltage na gamit, tapos walang heatsink yung IC, kaya lumambot yung hinang sa PCB kaya natanggal buo.

Newbie questions, anyone can share their input...While at the task of re-casing a t-amp and improving some connectors, can I wire it to facilitate a 3-way selector switch ala Tuner/CD/Aux selector switch?
Where can one buy good signal wires for the rca connection when upgrading its connectors?
Thanks in advance.

Sirs, Something bad happened on my T-amp. Yesterday when i went home from a whole day of work, i turned on my T-amp and found out that it was not working. The led power indicator was okey, but there were no audio coming out from the amp. :'(
But thanks to john of Dai-ichi megamall who was very Accomodating. He promised to replace the T-amp as soon as their stocks arrived. More power to you John!

Frequently Asked Questions about Tripath based amplifiers
What Tripath based amplifiers are available?
[41Hz]
AMP1 ~54 USD, AMP1-B ~63 USD, AMP2 ~89 USD, AMP3 ~25 USD, AMP4 (not available yet), AMP5 ~78 USD, AMP6 ~39 USD
[Autocostruire]
Class-t-amp2020 ~80 EUR, Fenice20 ~55-72 EUR
[DIY paradise]
Charlize ~90 USD
[Sonic Impact Technologies]
SI 5066 T-amp ~39 USD, Super T-Amp ~139 USD
What amp is going to suit my needs best?
This depends on your system, needs and tastes. (Future opinion section?)
Refer to the table below
How do I assemble it without killing it, the rest of my gear, and myself?
Read up on soldering and circuit design
Triple Check your work
Ask questions on the forum
Can the amps be bridged for more power?
No. The Tripath chips commonly referred to on this forum are already bridged. No further bridging or paralleled operation is possible.
How much power does the amp put out?
Not much. The Tripath chips TA2024, TA2020 and TTA2021B are all rated for about the same power. You can expect about 13 watts RMS into 8 ohms. This will vary a little with power supply voltage and current.
What size power supply do I need?
At least 12 volts, 1.5 Amps. It is best not to run the Sonic Impact over 13V, and a heatsink is a good idea at that voltage. The 41Hz AMP6 has a built in power supply. A 3 to 5 amp regulated supply is plenty. The amps typically draw about 300mA with a musical signal.
Can I run the amp on battery power, e.g. SLA? What size SLA?
Yes. All the common Tripath amps run well on 12V batteries. A 7AH battery is a reasonable size. There is no reason to prevent experimenting with your car battery. Its "too big", but, hey, its free to experiment with.
Why does my Sonic Impact lack bass?
2 reasons. Input caps and power supply. Both need to be changed. A mod FAQ will be added here. Or see
http://myweb.tiscali.co.uk/nuukspot/decdun/t_amps.html
http://www.michael.mardis.com/sonic
Is this a digital amp? Can it be connected directly to a digital signal?
No. This is a class-D amp. This means a switching amp, not digital. It is entirely analog. However, class-D has many advantages over classes A and AB. Not the least of which is superb sound quality.
How do I remove the case of the Sonic Impact?
Remove the little rubber feet on the bottom. You will find a small screw under each. There are also 2 screws in the battery compartment.
Which input cap is best? What size cap do I need?
No one has yet to establish a “best” cap. Any good metalized film or film/foil cap will make you happy. Some users have reported preferring electrolytic cap, such as Blackgate, for more bass impact. A value of 2uF or 2.2uF is as large as you need. Voltage can be as low as 5V. Bigger sizes, say 4 to 10uf, will definitely give a big switch-on thump.
Do I really need an input cap?
Yes you do. The input cap is essential to the proper functioning of these amp. Without it, you will likely get massive DC offset, thus ruing your speakers, the amp and possibly other gear.
Do they really sound that good?
Yes! Properly implemented, these amps are phenomenal!
What type of power supplies work well with Tripath Amps?
For some reason Switching Mode Power Supplies (SMPS) give excellent results. Then again, others like 12v. batteries.
For voltage, amperage, and wattage, refer to the table above.
For the Ideal Voltage, the First Voltage is a good start
What default power connector size is used for the SI 5066 T-Amp?
2.1mm internal diameter with the outside the ground and the inside positive.
What is the difference between Single Ended and Bridged?
[SINGLE-ENDED AMPLIFIERS VERSUS BALANCED OUTPUT]
In general, the bridged chips have been known for better sound quality
Will these low power amps be able to drive my XXXX speakers with 8X db sensitivity?
Many have good results even with as low as 86 db/m. Room-size, preferred listening levels etc. all count.
Which amplifiers require break in?
Charlize, SI T-Amp ...
Charlize Specific
General Information
What are the dimensions for the Charlize?
3 x 2 x 1 inches for Width, Length, Height
What is the gain for the Charlize Amplifier?
Gain is 12 db if ratio of input resistors is 1:1
How do I remove the start up "Pop" when turning on the Charlize?
This involves using a rotary switch and a resistor to create a "soft start" circuit.
See near the bottom of the [Charlize Webpage]
Modifications
Aircore Inductors

Thanks for that, oweidah. Did you have yout T-amp modded? New measurement is flat down to 10Hz!

Finally finished putting ding's charlize in a transparent acrylic enclosure. Tested it for about an hour and immediately, you'll notice that it sounds smoother, with bass na gumagapang ang very extended highs. Malapad yung soundstage, however, mas forward yung voice. I was using SMPS with the amp, then connected my tweaked SI next. The SI sounded rougher, mas magaspang, di kasing swabe ng Charlize, and medyo kulang ng buhay, not as lively as the Charlize. I'll be assembling my 2 Charlizes and mono-mono setup. Then I'll do further tests and tweaks.
Tripath did stop production of the TA2020 IC used in charlize, amp6 etc. Cost wise, mas mahal sya kaysa TA2021 na SMD, and according to Tripath's specs, both ICs should be identical. However, Michael Mardis did compare amp 3 (TA2021) and AMP6 (TA2020) and according to him, amp3 is tiring to listen to after a while. So magiging collector's na yung kits based on the TA2020 IC. I'll try to post some pix of ding's Charlize, in all its naked glory. hehehe
-
I tried using T amp last night with a 14ga wire and ang hina ng sound. I switched back to Ixos 6006 11ga wires and it was louder and had more bass. Maybe sometimes you just need to use thicker wires for more bass?
-
More bass doesn't necessarily mean deeper bass. For the SI t-amp, you need to change input cap from the default value to get the theoretical 10hz limit. I think I made the computation on how you'll get 10hz from an earlier post.

kanya2 experiment speaker cables.i'm alternately using chord carnival co.silver plus and qed silver anniversary with the t-amp and both works well. the qed silver anniversary is thin -around 16ga. but the sound is well controlled tight bass, though not that deep.Thanks for that, oweidah. Did you have yout T-amp modded? New measurement is flat down to 10Hz!
im using stock t-amps. quite content despite the not so deep bass, no slam but the mids/highs quality more than compensate, enough for me not to miss the 320bee. havent made up my mind whether to have it tweaked- (change input caps - what brand and value best suits my taste and, bypass/get rid of volume pot)
down to 10hz.....wow! baka masapawan pati ss amps! ;D:o

tama ka sir dohbert, gumagapang talaga ang charlize at ang soundstage nya ay malapad esp after i had spaced out my speakers far from each other. sa stock setup contento na ako after only 4 hours of use (stopped using it for now dahil sa naglolokong psu ko). pansin ko medyo matinis ng konti ang highs pero sabi ni yeo na mag memelow down daw to after the break-in period. imho the charlize is worth every penny even it is more than twice the price of SI amp.

bakit? may mga closet t-ampers ba?....hindi pa naglaladlad?...joke lang po at no one referred to in particular ;D
btw...has anyone tried the t-amp for the center channel of an HT setup? if your avr has full 5.1 pre-out features, pwede gamitin ang t-amp as external center or surround channel amp. and since the t-amp's strength is in the mids and highs, it might be a better alternative to using the avrs amplification. (baka mas malutong ang bigkas ng dialog..sssssh***t!) ;D
now as to gain, hindi p0 yung gatas. :) im fortunate to have a sony tan330es amp with an attenuator- default is at 12oclock. i tried the sony for LF and the t-amp for HF. it solved the bass deficiency of my previous setup (two t-amps biamped), but i had to adjust the sony amp's attentuator to 10oclock to achieve a balanced output, while the t-amp is at full volume. btw, both amps are still driven by the yammy avr (front pre-out)..now ill try the spare t-amp as center channel amp..hehehe
-
I just watched a whole movie awhile ago with the T amp.
Its bass was sufficient, but I just had to crank the volume to almost maximum. This thing is truly amazing. Lalo na pag may music yung movie, ang detailed ng song.
Naisip ko tuloy yung sinabi ni oweidah na gamitin to for front amps.

it could have been mababa ang sensitivity ng bookshelfs mo or mababa ang impedance ng speakers (below 6ohms) remember sa review ng Audio Innovation - by Dan Marx www_danmarx_org. at ng 6moons audio reviews Sonic Impact Class-T amp. eh dapat daw at least nasa 90db++ ang sensitivity ng speakers before hooking it up para hindi hirap ang amp. kung baga madali i-drive ng amp yung speakers. tapos pag mas mababa naman sa 6 ohms parang mainit masyado sa amp yung operation. ewan ko lang ha? im not a techie, pero based on my expirience last 1992 nung naka sira ako ng 2 JVC vintage amp eh dahil sa pinag parallel ako ang dalawang speakers na 4 ohms. kaya ayun sunog ang amp!...

may nag email sa akin last thursday na nasiraan din ng amp (itago na lang natin siya sa name na Berting) and sabi niya nangamoy daw yun t-amp niya after playing for an hour or two using a "regulated" supply na zig-zag yata o zorro ang brand or whatever. di ko na naitanong speakers niya pero he is asking kung bumibili daw ako ng sirang t-amp. ang sabi ko hindi eh. ::)
so ingat lang kaunti sa pagpili ng speaker, power supply etc. medyo maselan ang durability issues...
-
the t-amp works wonders when used within its limits, tempting minsan sa iba na gamitin sa bigger speakers. but this amp likes speakers with simple crossovers and stable impedance. finished tweaking the t-amps i have and was more satisfied with just changing the electrolytic and adding a pair of 1000uf uf near the power pins of the chip and changing the cap in parallel sa speaker terminals to .22uf solens
-
Yep, yan nga sabi ko sa earlier posts sa SI/Class-D amp tweaks na thtread, iwasan gumamit nung mga regulated na 13.8v na gamit pang charge ng batts for your t-amp. Ibaba yan sa 12volts to be on the safe side. At 13.8 dapat may heatsink na yung tripath IC and at the same time dapat maganda tolerance ng PSU, pag hindi, sure di tatagal yan. May isa rin na bumaklas yung buong IC, I think malamang gumamit din ng mataas ng voltage for the t-amp. Ibaba to 12volts just to be on the safe side, kung sumablay pa ng 10% yung PSU, nasa 13.2 volts ka lang, di masisira pa, pero at 13.8v tapos 10% leeway, nasa 15.1. Sure sira yan.
-
di kasi nakinig kay master DOHbert eh, pinilit pa yun gusto na psu o baka naman sa speaker din? kasi yun kay ianmorales sabi niya batteries daw gamit niya eh. ::)
-
yup either sumobra voltage or nahirapan yung chip. checked the pcb dami pang room for improvement
-
so yun nag email sa akin most probably nasobrahan sa supply. yun naman kay ianmorales nahirapan sa speakers kasi batt supply siya.
so, ayan dalawa na ang dapat tandaan ng mga local audiophile t-amp users natin. ano pa ang maipapayo ninyo mga masters?
-
Class-D amps don't like complex loads and secondly they don't want very low impedance speakers. It'll play ok at 4 ohms, but remember, speakers are not purely resistive like resistors. Umiiba ang impedance load depending sa frequency na prinoproduce. At 4ohms load, the chip is definitely going to run hotter than with a 8ohm load. Tapos, hindi sa buong 20hz to 20khz range na 4ohms yan, may parts na bababa or tataas yan. So if you're using 4ohms speaker, and medyo complex yung x-over, suggest ko rin yung sabi ni Master Jojo, babaan ang volume level. So isang minus na yung 4ohm speakers. Secondly, ayaw na ayaw nila ng complex loads, kahit yung speakes at 8 ohms. Speaking from personal experience, I DIYed a 3-way speaker, 8-ohms sya dapat, pero somehow did something wrong sa x-over ng tweet and midrange, such that nasa 4 ohm na yung load at x-over point, which is around 4khz. When I played the t-amp, at moderate levels lang, nasa 84db lang, nag auto mute yung amp tapos bigla lang babalik bigla pag nawala yung complex load. It's not a voltage or volume issue, dahil regulated man or SMPS, same thing happens. Pero when I tried a full-ranger or 2-way commercial speaker (6 ohms), kahit mas malakas pa yung volume, di naman nag mu-mute, although split second lang.
One important thing to remember, Sonic Impact's ta2024 chip, whether tweaked or not, will start producing 10% distorting at 4 watts with 8ohm load and around 7watts for 4ohms load. So pag nilalakasan nyo, in effect, pinepwersa na yung SI to play loud but distorted music. One way to somehow increase output wattage without going to distortion early is increase volatage input. So dyan pumapasok yung 13.2 or 13.5 volts, you can push the amp a bit more before going to distortion, but then again, the TA2024 chip will start experiencing heat problems, thus the need for heatsinks. Ang TA2021 or TA2020 chip na gamit ng amp6 or charlize has higher voltage input tolerance than SI's ta2024. Safe sya at 13volts without heatsink. Some even pushed input voltage to 14v and the chip amp was not that hot. Yan yung maganda sa IC, nakatayo, thus di sakal yung heat dissipation. Yung Ta2024, SMD, sakal yung bottom part, nandun pa naman yung copper side, sa ibaba, right on top of the PCB. So pag tinignan mo yung SI, bottom side, may mga butas butas sa board. Yung 1st batch na SI may solder na tunaw dun sa butas butas para yung copperside ng TA2024 is dikit sa solder, thus helping in heat dissipation. Yung mga SI na labas ngayon, wala nang hinang sa ibaba, kaya lagyan nalang ng heatsink sa itaas ng IC. Medyo mahaba yung post, but hope it helps.

love the amp for what it is. pero ako kasi mahilig mangalikot...hirap magsolder ng smd >:( (pasmado kasi hehe) pero nakakatuwa ring pagaralan, at least nainitindihan mo kung bakit effective ang tweak na ito or hindi.
-
sayang yang ta2020, discontinued, pinalit surface mount >:(

so yun nag email sa akin most probably nasobrahan sa supply. yun naman kay ianmorales nahirapan sa speakers kasi batt supply siya.
so, ayan dalawa na ang dapat tandaan ng mga local audiophile t-amp users natin. ano pa ang maipapayo ninyo mga masters?
opo,,,,,sundin p0 ang payo ng nakaka-alam..dami naman supply daiichi at meron din daw sa tabi-tabi ;D ....talaga nakakagigil biritin t-amp kasi ang ganda pero dapat magpigil....
user initial impression on t-amp as external/center channel amp - hooked up sony dvp ns400d center channel out direct to t-amp; while front channel out split to sony es amp (LF) and t-amp (HF). No surrounds. watched dvd dts movie ....all i can say is OOOHLALAH :o :o :o
*but medyo tricky magtimpla kasi bw602 fronts at one(1) unit wharf diamond9.1 fed from only one channel of the t-amp.
-
baka naman kaya mas matibay yun mga naunang labas ng t-amp kaysa dun sa mga bago lang kasi wala ng solder pad that serves as heatsinks? hhmmm....
ang ikatlong dapat tandaan ay... hindi dapat biritin at ihataw ang t-amp, masusunog ang chips nito. dahan-dahan lang at ibaba na ang volume kapag nag distort na ito. anymore tips mga masters?
kung birit at hataw ang gusto dapat Mackie amps ang bilhin at hindi t-amp. ;D
-
OT: this just popped up in my brain like a light bulb...
Now it seems that Dai-Ichi is actively "carrying" orders for t-amps. We all know that you can buy bulk orders of these Tripath chips right?...... So I won't be surprised to see a Dai-Ichi "rendition" of the T-Amp!
Not so long ago, Cerwin Vega drivers were said to be oem'd by Dai-Ichi, next thing most drivers by Dai-Ichi looks like CV drivers. They even have those Pyle Driver looking models. It's good that they apply the R&D to their product line. Take for instance their floorstanders nowadays which looks a lot like those highly priced speakers. They also carried the automotive amp brand Fenton whom which at close inspection looks a lot like an Alpine V12 amp.
;D ;D ;D

Nakausap ko si john of dai-ichi regarding the t-amp. And he told me na gagawa sila ng version nila ng T-amp, don't know lang ung when nila ilalabas here sa pinas or pang overseas lang ang kanila.
Regarding my speakers which i use on my T-amp, its a Roy Allison referrence speaker and i dont think na makakasira yon ng T-amp. I think my unit is the goat unit, kasi when i turn the volume pot to 10 or 11 o'clock distorted na sya. And im not a hard listener i only used it for around 25 minutes or less.
-
SI under a normal load of 8ohms should start distorting at 1 o'clock position. Is your speaker rated at 4 or 8 ohms?
-

Is this regardless of the impedance of the pot used? I was thinking, the higher the impedance of the pot, the farther you have to go before distorting. Is this correct?
Thanks.
-
sirs...short rejoinder lang p0...after yesterdays switch to the sony es amp for LF duty, i switchd back today to a pure double t-amp "biamp" config....although the sony es amp solved the bass issue, naapektuhan ang mids, sad to say even this well-regarded ss amp is no match for the mids of the miniscule t-amp....yes using different amps in a biamp config can be done provided may attenuator (to control the gain) but the overall effect is uncertain. tapat-tapat lang.....just my sunday mamera :)
-
Sorry, didn't make myself clear, the 1 o'clock position refers to 50kohm vol pot. Actually, whether you use 50k, 10k or 100k, the amp will start distorting at 4watts at 8ohms and 7 watts for 4ohms, I think I mentioned this already in previous posts. So use your stock 50kohm as reference, push it to 1 o'clock, register the db output. Then change your pot to whatever value you like, then compare at which position the new pot will start distorting as per db measurements made beforehand. Remember, don't push your amp too far beyond distortion point. Once the amp goes into distortion, may lulusot na mga DC voltages which could damage your tweet's coils, aside from being harmful to your amp of course.
-
as a point of reference i never push the volume past 12' o clock...usually nasa 10 o' clock lang sya. naisip ko lang...with a chassis as bug as what oweidah bought pwede pala 3 unit ng t-amp and ps + input and ps mods....pwedeng six channel amp ::)

gusto mo ng scoop? eto scoop....
wala pa ang stocks ng t-amp pero ang dami ng nagbigay ng downpayment sa importer na ito! ang matindi pa dito, backlog na ang manufacturing ng t-amp dahil sa super-t! kaya magpaparating na lang ng chips ahoy at sila na ang mag-assume ng production.
kaya tuloy malabo na ako magkaroon ng t-amp. :'( :'( :'(
sa tingin mo makakabili pa ako ng t-amp sa tindi ng demand? ohlala. ;D

dohbert,
anong pot gamit mo, ALPs ba yan?

mga masters,
ano po ba ang magandang gamiting "signal wires" sa tweak? may ma recommend ba kayo na pwede gamitin kasi yun friend ko naguguluhan bakit daw ganun? yun da best tapos yun pababa ng pababa.

ahh, update, mukhang ok yung chip me voltage galing sa output ng pins, kaso pagdating sa left speaker outbaligtad, pero sa right speaker out me offset >:( wala naman akong ginalaw sa output part, sa input lang...pakialamero kasi hehe ;D
-
Naisip ko tuloy yung sinabi ni oweidah na gamitin to for front amps.
and center channel too ;D (kung may center channel pre-out ang avr mo.) sa HT..salo na ng subs ang LF so adjust mo na lang ang cut-off xovr freq. ayos na.
Ang original idea ko talaga is to connect 3 T amps to a DVD player with DTS decoder & outs.
2 channels handles the front, 2 for the surrounds and 2 for the center & back surround.
So may surround system ka na for just P6k.
Kaasya sana 3 T amps sa casing na binili ni oweidah kung gustong i-integrate lahat sa isang casing, problema lang daw yung volume control for the 3 T amps.
-

ikaw naman, kaunting pasensya lang. ;D ;D ;D ok pa yan... or baka yun pinakialaman mo lang ang nagloloko?
-
jojo: pareho ko nang pinalitan yung input stage yung dalawa, ung isa lang yung nagloko ??? baka me part lang na bumigay, kasi halos lahat ng circuit paths na test ko na, ok naman.
-
possible na may bumigay na parts pero yun chip lang ang active part diyan eh, all other parts are passive.
-
since i encountered some obstacles, my next project (6 channel t-amp) will just include mods sa electrolytic caps and yung coils. i will use it as an amp connected to the outs of my soundcard.
-
at, last nabihisan ko na si charlize thru the help of sir oweidah (for the chassis and smps).
kulang nalang ako ng alp pot and maybe modding the input cap later.
heto po mga pics.
top view: 3-output 12v, 5.2A smps on the right (from alexan = P1.1k). still got room for my upcoming SI t-amp (still in the US)

-
nice GneW 8) judging from the size of the case and space at the back i would probably use smaller speaker terminals if i will cram 3 t-amps

yup, you can try the binding post used by dohbert. paano ang volume controm mo, 3 pots?
-
Regarding DC offsets, kadalasan umiiba or tumataas ang DC offset after changing the input cap. Ok lang may DC offset, wag lang lalagpas ng 150mv. Yung amp6 ko 80 and 100mv, ok lang. Yung Charlize, mababa, nasa 30mv or 40mv lang. Sukatan mo ng 2.5volts sa input cap and board na connected sya just to make sure tama pasok sa caps. Then check the dc offsets sa likuran, pwedeng walang offset kasi sablay sa front end na input caps. Yung SI btw, mataas na talaga DC offset nyan by default.
-

...sensei jojo...kontento na p0 ako...biamp t-amp ....stop na...time to enjoy d music n films ;D
p.s....ano ba meron si petite cute t-amp bat pinagkakaguluhan? ::)
-
Pahabol, isa din palang tip yan sa tweakers ng input cap, check DC offset right after changing the caps, make sure its not dangerously high. Epek ng DC offset sa speaker posts, yung speaker drivers mo are receiving dc voltages which causes the driver cone to push out a bit over its regular resting state, thus pag bumabayo na sya, di na ganun kalaki yung tinatakbo ng cone since yung stop position nya is nakalabas na.
-
Magandang wires na na test ko is yung Belden 8760 ba yun na patched stereo cable, I used it with ding's unit, medyo mataba yung wiring, di ko sure kung kasya sa SI, sa charlize nagkasya. Or, as suggested by many, cat5.

-
Gnew,
that's a nice looking amp you got there, congrats!
-
I think the maximum allowable DC offset for any amp was stated to be 100mV (0.1V), any higher than this and your tweeters heats up and there could be something wrong in the amp. Anyway this is what I live by when I build amps.
High offsets are caused my many factors such as component mismatch, error corrections etc.
-
Gnew,
that's a nice looking amp you got there, congrats!
thanks sir jojo.
checked the dc offset of my amp, right channel is 25.6mV and the left is 16.2mV. bakit di sila pantay? kelangan ba talaga tong pantayin?
-
Ganyan talaga, di talaga mag papantay yan, tolerances ng gamit na parts.
-

you could have it tweaked to bypass/ get rid of the volume control knob. Replace it with power on/off switches - one per t-amp.

ewan ko ba... kayo lang naman ang nagkakagulo eh. :P
huli kasi dito, nauna na yung mga classD amp fanatics ng ibang bansa....

those are already pretty good readings GneW, though for such a precision rig it should have been better. I have built amps that have less than 1mV offsets in the past but just the same, as long as you are within 100mV it should be ok. and there is probably nothing you can do to decrease nor balance this offset as per Charlize design.
don't worry, you're readings are ok, if I were you I would indulge and enjoy listening to that amp. :)
cheers

iniisip ko na nga kung bibili na ako niyan t-amp, puro ako tweak at upgrade ng t-amp ng ibang tao pero ako wala... t meron pero amp wala. :'(

Bumblebee, pag walang stock within the week, you can get mine if you like... yun nga lang, packaged with a regulated psu (highly recommended by other users.) Dont worry, same prices as I bought it last week and you get both the receipts for warranty purposes, etc. pm me if interested.
-
Yep, got both amp6 and Charlize. Suggest ko na instead of getting amp3, get the amp6. Nuuk (Nick) from DIYaudio posted his impressions of both amps at tnt audio. The amp6 he said was less tiring to listen to.
" Instead of making comparisons with the other 2020 amps, it may be more interesting to compare the AMP-6 with the AMP-3, even though they use different chips. I found the AMP-6 much smoother than the AMP-3 and not quite so clinical (although still very detailed). Where I had found the AMP-3 very slightly fatiguing to listen to after a while, there was no such problem with the AMP-6. Detail was excellent and the sound stage wide and deep. In short, a very good sounding amplifier, and, with better DC blocking capacitors, something to rival the other 2020 based amplifiers!"

oweidah,
di naman. inoffer ko lang since mabuti pang pakinabangan ito ng ating kapatid na bumblebee imbis na nakastock lang dito (since I cant mod it pa due to time constraints). Its better appreciated than stored ika nga. Besides, meron pa rin akong ilang gears na hindi pa nabe-break-in at stock lang. However, I dont mind keeping the T.amp if no one is interested. La naman itong shelf life. hehe

Oweidah,
I tried bi amping the SI yesterday on my bookshelf (dati sa Floorstanders kasi). I used one with a power supply for the lows and one using batteries for the highs. The one with the batteries was new (di pa break in), but the one with power supply has been used for several days already.
The soundstage is wider, but medyo bright sya minsan. May times masakit sa tenga. Di kaya dahil bago pa yung ginamit ko sa HF?
-
@matzter; nope most likely mas madaling i drive yung tweeters, kaya naiiwan ang mids. And yes the soundstage is wider kasi separate amps drive the woofers and tweets.

matzter, both my t-amps use one and the same power supply 13.8v 6amps. generally ok naman and if it seems brite, i adjust treble of yammy avr preamp processor or the volume of the t.amp used for HF.
try mo muna switching the t-amp power supplies to confirm if its still brite; or use regulated ps or smps (highly recommended and i just might switch to this ps) for both t-amps para uniform power.
-
thats what i forgot :-[ lessen the volume of the amp na nakakabit sa highs, medyo kailangang timplahin nga lang.
-
mga sirs,
any recommendations for a locally available regulated PSU for T-Amps ?
also , anyone tried using them with 4 ohms not so efficient speakers ?
tia

just use the SMPS psu for the t-amp. it is highly regarded by many users and available in alexan. ;)

i wouldn't recommend though using the t-amp with not so efficient speakers....
-
wait a minute kapeng mainit! ;D
if you will bi-amp (that means 2 t-amps), you would probably connect them to a preamp that has 2 outputs or use a y-connector right? bakit kailangan pa adjust yun volume papunta sa HF?
what I mean is the input would be the same for both of the amps right? and with the precision of these class-D amps a 5% or better tolerance in their differences in manufacturing can be expected so a 1Vpp input on both amps would yield an output somewhere near a 5% or better accuracy, hence, we can say that we are still providing the same amount of power for the HF and LF but their interactions would definitely be improved since reactions of the LF driver would/should not affect the amp driving the HF right?
hay, don't mind me... hindi lang ako makatulog...

guys,
friendly advice lang po mga sirs and masters. what you feed your amp is what you'll hear. this includes your source and your power supply.
so please, feed wisely.

ginagamit ko avr para timplahin ang volume at tone controls, hindi timpla ng pekakaps.... ;D
what i meant is pwede din, (pero di ko ginagawa), adjust vol. t-amp used for HF para humina ang HF kung preamp (esp if tube pre) lang ang gamit na walang tone controls as tru blu audiophiles do. di ba pwede yun sensei? ;D
guys,
friendly advice lang po mga sirs and masters. what you feed your amp is what you'll hear. this includes your source and your power supply.
so please, feed wisely.
:-X
Agree! spin-a-win! kaya hindi na ako nangarap mag-upgrade level-up gears eh ang gamit ko naman ay mostly inferior quality cd/dvds ;D (huwag pamarisan!).... pagkaganda ng gamit eh kung gagamitan mo ng kung anong source lang eh wala din!...... kabuuan ng setup kasama ang mga source quality.
system synergy para world peace ;D

anyone want to wind their own torroidal inductors for the t-amp ? we can buy the cores from www.rsphilippines.com part no. 467-4239. we can use 22 awg wire and it requires 14 turns. ::)
-
i wouldn't recommend though using the t-amp with not so efficient speakers....
thanks for the advice sir ...
88 dB yung efficiency ng speakers ko sir ... medyo mababa nga kasi mga 12:30 pa lang may distortion na .
i had some free time lately so sinubukan ko ring mag bi-amp.
used the T-amp for the highs and my integrated tube for the lows... and the sound is pure magic ... <well at least to a newbie like myself :) >
i can crank the juice up on the t-amp now .
but i think i will still need a good PSU ... i believe you have some extra ... can you pm me the details ?
also found out that there is a newer version of the T-amp . it now comes in an aluminum case , with better input/output terminals and an AC wall adapter.

hi bayonic,
are you using a preamp in your biamp config or y-adaptor lang from source to the amps?
if not, i suggest you use a preamp.
yes superT in aluminum casing...but at increased cost $139?
happy listening...enjoy!

well current inputs say its sounds much better than a stock and even tweaked t-amp...who wants to try?? ;D

at the moment .... Y-adaptor lang sir .... kasi yung balak ko naman talaga is to use the T-amp for an Ipod-based mini-system in another room ... but now kailangan ko na maghanap ng pre-amp :)

The CAP-RACK
Boot Camp for Capacitors-in-Training
Here is an answer to audio capacitors that require an inordinate amount of break-in time before they sound even listenable: the cap-rack!
The concept is to build a device that you can easily plug components in and out of from stuff you probably have lying around already. The cap-rack keeps the capacitors polarized while subjecting them to large charge-discharge cycles. A few days is guarenteed to break in even the most stubborn of exotic capcitors!

just a question sa mga Sonic Impact T-amp users, totoo bang tunog tubo ang T-amp? paki justify naman po before I made a purchase. Thanks!
-
mga sir,
pwede bang magkabit ng switch (dpdt) sa input to by-pass the pot? para kung sakaling magkabit ng pre-amp pwede na e defeat ang pot ng t-amp without desoldering the connections. di kaya to makasira sa pot na maging shorted na?
-
wire the switch so that the pivot arm of the switch goes to your amp. then wire one of the poles at the wiper of your pot (the one used as input, the other one is at ground potential) then wire the other pole of the switch to the governor of the pot. this way the input of your amp selects between before and after going to the pot. this may be a useful option but be wary because a flick of a switch will cause your amp to go to max power. see to it that you use a high quality switch for this would be used in the signal path, such a purist's nightmare in retrospect.
a more clever approach would be to use an audiophile grade Potter & Brumfield dpdt mini relay as your signal switcher, even an Omron relay would probably be suitable if you are not a purist.
or you can always turn your pot to the max and save you the time and effort of installing the switch.

yan ang plano ko sir to cut only the positive input going to the rca in and pot using a dpdt.
magkano kaya tong odyopayl greyd dpdt switch? kung mahal at hassle lang, e max ko nalang ang pot kung may pre-amp na.

just a question sa mga Sonic Impact T-amp users, totoo bang tunog tubo ang T-amp? paki justify naman po before I made a purchase. Thanks!
sir hanns1976, i use s.i. t-amps but im not a tubero/ tube component afficionado. no regrets i took the t-amp plunge :) u gotta hear it to believe it. i'm referring to stock s.i. t-amp pa lang. what more pag modified na ng mga expert diyrs natin dito! s.i t-amp if its still available @daiichi smmegamol = 2k + regulated power supply or smps or sla battery around=850 at diy mo na lang if you want to re-box & tweak. 3k- reasonable risk dont u think so?
1. dont expect much in terms of volume. this is a 6-8watt amp@ 8ohms amplifier. Esp. bass/LF <100hz, eto weak point ng t.amp BUT do check out the midrange and HF quality...malufet! this amp excels in clarity, detail and soundstage. basta use it w/in its limits.
2. very impt- use a good & stable power supply, huwag mo tipirin dito.
3. i suggest- use a preamp (for audio) or preamp/processor (hindi lang pang audio pang-HT pa)
U r in for a pleasant surpise....happy easter egg-hunting (not sa pier ha...) ;D ;D ;D
pssst....atin-atin lang 'to....kita mo yung previous page, dami pagawa casing t-amps? ibidinsha ba yan dumarami closet t-amp users? nagtatanong lang p0 ::)

yan ang style nila maski noon pa, I'm sure nasa R&D dept na nila yan. mabuti nga yun at ng hindi na tayo kung saan saan pa bumibili. ;)

unfortunately the budget does not permit it. kung mapapansin mo yun 100W na flying mole nasa 30K+. ;D ;D ;D
factors that I need in a plate-amp is reliability, flexibility, accuracy, speed and power. unintelligent frequencies naman yun lumalabas sa sub so baka hindi na ako magpunta sa digital domain of amplification.

tama ka nga sir mahal ang mga high powered digital amp. pero merong mura na kit at 180 euro ata na 100 wpc sa audiodigit. tripath din ginamit na chip.
bakit kaya sa car audio di gaano kamahal ang mga hi-powered class D amp? effective talaga ang class d na sub amp sa kotse dahil lesser strain sa electrical system. tripath din kaya ang gamit sa mga car sub amp?
-
hhmmm... I don't think that class D is much less demanding sa electrical system. mas efficient lang ito in converting/amplifying signals that's why there is less heat. but the current demands would be as much as an amp in class AB mode provided we are driving the same sub. another bonus is the smallish package that class D offers, more headroom/legroom for the car? ::)

I have been tinkering with these two ladies the yesterday and the whole afternoon just to make them work so I can gently break them in. Got them working correct and true as per my measurements and my initial impressions with Charlize is that she is so clear, the music is so clean but not to the point that it was sterile. At some point during female vocals the sound even tends to be analytical. The highs are so lush and clear that I can even hear the smallest tap of a cymbal, however at prolonged listening the sound seems to be a bit tiring, probably due to the highs which are pretty much extended - considering it has been processed digitally by the amp. I wish that I may still have some time with these ladies for them to be fully broken in and trully realize their true potentials. Oh by the way, Monica is also lushy in the highs department which is probably why I will use a tube buffer during break-in and while they undergo further testing.
DISCLAMER: These are just my initial observations and should not be considered as a review.

ganda ng combo mo sir jo. anong brand ng smps gamit mo? yung charlize ko nag tame na yung highs after around +/- 20hrs playing time. dunno if maypagbabago pa to kasi sabi ni yeo na burn-in time daw ay 100hrs.
-
I tried using a couple of SMPS for Charlize before just for testdrive purposes, unfortunately my earlier listening observations regarding the use of SMPS was still present and I still don't like it. At the moment I still don't know what is going on in the highs and mids that is being caused by the SMPS, and to put it bluntly, I don't like what I hear with that type of PSU. So I opted for an old fashioned linear regulator. I was told by a fellow diyer in canada that speed is the key with digital amps and that is the difference between SMPS and linear regulators, however, I still haven't proved that to myself but I'm seriously considering the thought.
Cheers,
JojoD

anong laman nito sir jojo?
ok lang ba iiwan na ON ang t-amp at very minimum volume or no volume at all para madali pag break-in? pwede din ba na ON lang sya na walang signal from a cdp?
-
Of course pwede, pero I always monitor the first 6 hours of operation, checking voltages every 30 min. If all is well iniiwan ko na yan naka power on.
btw, this is what's inside...

Ganda ng gawa sir, alam ko kung kanino yan, hehehe. Btw sir, na try mo na lagyan ng 10,000uf cap before the power input ng boards, tapos lagyan ng snubber across it? I might use this configuration while attached to smps. Baka maiwasan yung high and mid anomalies na na-experience nyo. What ya think? Btw, nakakita narin ako ng torroidal trafo sa raon, medyo mahal nga lang singil. Merong 16v@8amp and 32v@8amp na taps. P850 yata bawat isa. I'm also contemplating on using torroids with the mur815s I bought from you before, tapos lm338k.
-
Dohbert, and other experts...need your inputs pls...My Charlize's right channel became less louder than the
left channel since yesterday. Tried switching the cables in left/right input, but the right channel remained less louder than the left...so I think there is something wrong with the Charlize's output in the right channel. Any thoughts guys....I hope the Tripath chip is not fried or busted.....Sayang ganda pa naman tumunog...heeeelp
-
PM sent sir, unlikely tripath and sira, its either merong output or wala, more likely sablay lang yung volume pot. I-off mo yung amp, then pihitin mo paikot ikot yung volume pot, exteme left then extreme right, then try again, kung ayaw parin, get a separate preamp with volume pot, rektahin mo yung input from rca directly to the board. Balitaan mo kami kung ano developments. Thanks

been there, done that. yun 10kuf in the input made things very slowwww, another internet-based tweak turn bad. snubber okidok for psu high freq damping, just compute for your corner freq. good luck

bottomline - YOUR satisfaction, contentment, etc - that's all that matters.
* waay pa pre-amp? ( sure doc jojod can give u good advice on valve (pre-) amplification that
matches with s.i. and charlize :))
* sadik kwais- b&w speakers - Bai & Weng speakers? ? ;D ;D ;D
b&w600i 90s model, hindi pa kevlar gamit sa mid/woofers pero metal dome tweeters na. saw the b&w product catalog noon kaya tinutukan ko na b&w. i think yung porma nung 600i parang monitior audio rs1 ngayon?

afaik, not available in stores. check out the pinoydvd/assorted buy and sell/ht equipment thread.
its now available in daiichi megamall :)
questions lang. since newbie pa ko di pa naman ako bibili nag high end lahat, so gamitin ko lang yung mga existing equipment, T-Amp lang dagdag ko.
1) meron na ko DVD player saka DVD shelf system, pareho may sub out, ska JBL SUB140. OK na kaya kung dagdag ko lang yung T-Amp sa shelf system, ie yung speakers din niya gagamitin? Or, since 4ohm stable siya, gamitan ko ng Targa speakers na tatanggalin sa auto ng kaibigan ko pag nag-upgrade siya, pagawan ko na lang ng custom cabinet? Then magagamit pa yung sub out para sa active sub.
2) OK na ba yung rca-minijack plug sa hardware, or monster cable na rca to mini-jack cable? saan meron nung cable (wala raw mahanap yung kaibigan ko sa megamall pagpunta niya nung wednesday e).

2) OK na ba yung rca-minijack plug sa ace hardware, or dapat talaga monster cable na rca to mini-jack cable? saan meron nung cable (wala raw mahanap yung kaibigan ko sa megamall pagpunta niya nung wednesday e). saka yung speaker wires na kasama ng speaker ng shelf system, temporary muna habang nag-iipon ako ng pambili ng speakers. pag nakabili na gamitin ko na yung dvd player lang, di na yung shelf system.

ProtegeManiac,
1. didn't got that exactly pero san mo gagamitin yun t-amp? sa fronts ba? i think si oweidah successfull ang integration niya ng t-amp sa ht niya so it is possible pero depende na lang yan sa speaker mo and DVD player kung pwede integrate.
2. pwede na din yun pero katagalan nag oxidize yan so linis mo lang. syempre mas ok kung high quality interconnects na ang gagamitin mo. take note: high quality is the keyword, regardless of brand. ;)

alas, she opened herself up to me... :P
sa madaling sabi nawala na yun ear piercing highs, finally after about 100 hours of playing on the background while I work, Charlize sounds great. everything is where they should, the highs are still clear, the low end seems to have been worked up too. the mids are up front and mixes well with the background.
but still - let's try not to compare Charlize's mids to the mids of a bat out of hell 2A3 running in SET, or the compressing bass of a PP EL34.
don't be fooled though, this lady plays Rock too, speed and accuracy rivals if not surpass most gainclone amps I have built. though dynamics can be an issue against a 3886 or a 3875 but then again a relatively sensitive speaker can make up for this loss. against an 1875, I noticed Charlize does not have that "crunchyness" or whatever it is called. however Charlize's efficiency takes it all away due to the summer heat.
head to head with a 120W diy'd leach amp, Charlize looses the battle at high listening levels. stress and dynamics is not an issue wth the leach amp even at high listening levels while Charlize has this nasty habbit of increasing distortion at increasing rate of conduction. but at low levels it is undeniable that her clarity shines through. who cares, nobody listens at those high levels anyway.
and lastly, only time can tell if she has the points for reliability and longevity - for all the amps she went into battle have excellent track records for torture and human abuse. so please - try to be gentle with her.
Farewell Charlize, it has been a pleasure knowing you.

@JojoD818,
1) 2.1 lang sana sa kuwarto :) hindi nga ako manonood ng DVD e, DVD layer lang kasi may isa pa ko na hindi nagagamit, nung may libre kasi sa TV yun na ginamit sa bahay.
2) kaya ko lang natanong na monster cable kasi akala ko yun lang meron nung ganun na cable, tapos yung sa rca to minijack sa hardware, naisip ko lang na baka madegrade yung quality tapos ma-disappoint ako sa T-Amp, dahil lang may part sa signal chain na super cheap (as in wala pang P40 :) ) na baka hindi naman designed sa application. baka may gumawa na tapos di naman affected ang sound quality. :)
-
sir protege...
connect t-amp input to dvd player's analog/rca out using regular interconnects and mini-plug (stereo) y-adaptor. analog/stereo sound lang naman habol mo d ba?
use sub-out dvd player to subwoofer rca input.
cables and interconnects- personal preference mo yan bro. :)

sir jojo,
malakas ba ang turn-on thump ng charlize mo? yung sakin meron pa rin even after installing the resistor. medyo mahina nlg siya pero nandun pa rin. ang stock SI wala talaga turn-on thump.
at saka ano ba ang magandang klase ng soldering lead. nakaka inis ang lead ko kasi di dumidikit sa binding post. ilang beses ko na kinikil ang binding post pero pangit pa rin ang labas. hindi shiny ang solder at rough ang texture. unlike sa rca inputs na konti lang at ganda na ang dikit nya. same soldering lead ang gamit.

hi,
nagsubok na ako different values while mopping up on the datasheet pero ayaw talaga mawala "totally" pero na minimize naman.
kung mag silver s.lead ka you can order thru RS Components, otherwise try mo yun Electroloy, siya ang pinakamaganda na nasubukan ko for locally available s.lead and suitable for general use. huwag mo kikilin, dapat kakapit yan mag-isa. here's a tip for you... use a high quality soldering iron with the appropriate power! ;) baka kasi kulang lang sa init! ;D

Try this, its free. ;)
When powering up, start with the source first (i.e., CDP, DVD, TT or what have you), Pre-Amp if any .... POWER AMP LAST (in this case, your T-amp) (with volume set to zero of course.)
Reverse the process when powering down. Start with the power amp (to drain the caps) ....
Im not sure if its the same with digital amps, but it has worked with high powered SS amps with monstrous caps .....
Let us know if it worked for you.
-
Ang SI wala talagang turn on thump dahil mababa sobra yung stock value in uf yung input cap, lagyan mo ng 2.2 pataas may madidinig ka na. Sa charlize, mahirap talagang tanggalin dahil nasa 10uf yung input cap, one solution is to change the input cap to something smaller like 2.2 uf or 3.3uf. Thanks

sir ccc,
tried this sequence in powering up but still the thump is there. the charlize amp is giving off the thump itself so even it is powered last u will still hear and see the speaker excursion. once i find a good input cap locally available sa amin i will replace it to a lower value as per sir dohbert.

sir oweidah,

sir protege,
btw you may also wana try connect the line out of your shelf system to the t-amp para pwede i-control ng shelf system mo ang volume ng t-amp (set the t-amp volume to full/todo)
if pwede, i think its better to use the dvd shelf system setup.
i think/sana may stock pa ;D
good luck!

sir oweidah,
Nakita ko din kasi yung mga NAD304 na for sale dito sa forum...baka yun na lang gamitin ko sa den, tapos gamitin ko yung T-Amp sa shelf system, lipat ko na to sa kuwarto. For a shelf system internal amp OK naman siya, pero since 2K lang yung T-Amp, mukhang OK na bang-for-the-buck upgrade, para di ko na palitan yung shelf system. pag wala kasi yung sub sobrang bitin e.

close your eyes, open your mind, throw away biases and listen to the music.
t-amp is just 6watts/8ohms...may limitations yan.
very important- use good power supply.
hopefully after a few hours or days of listening, u will post initial impression/review.

ccc,
it's not the sequence that's incorrect - it's the amp that has the inherent turn-in thump. ;)

JojoD,
Hhhmmm, interesting. Bakit nga ba; cosidering that thumps from bigger amps with bigger caps can be "tamed" by the sequence? Does it have something to do with the amp being digital or sobra laki lang talaga yung caps na ginamit?
Would it be the same ("cannot avoid thumps") with modded T-amps?
-
the thump is there even if there is no source. so power up sequence has nothing to do with it. though what you described is the safe/proper sequence for power on/off (in reverse) which should be practiced by any self respecting audiophile.
btw, bigger amps are not tamed by the sequence, any size amp with an inherent turn-on/off thump would still be heard even if you follow such procedures/sequence. that is why big ss amps that requires huge current at turn on due to massive size filter caps have inrush current limiters and speaker time delay circuits.
--------------------------------------------------------------------------------------------------------------------------------------
the Charlize thump issue is due to the internal inverting amp, having the non-inverting input at Vcc/2 all the time which will then cause the input cap to charge therefore having a momentary time where DC is present at the input. once the input cap Ci is stable, normal dc decoupling and ac coupling commences.
-
ccc,
by the way, fyi. the problem is caused by a too large input cap and not by a filter cap. changing the input cap to a smaller one will alleviate the problem but will cause a significant roll-off at low frequencies.
cheers

shukran bai! :)
afwan bai. in my case i will modify the charlize only as it will power the LF. dunno if the SI will benifit any mod if used for HF.
btw, change also C10 (the cap in the middle of the inductors) to 640uF of good quality. it will have significant improvements over the stock according to the gurus of diyaudio.

Hhmmm, I don't mean to argue chief, but not in my case. With other amps, inadvertently not following the sequence doesn't seem to be a thumpy affair. But with a Tono12au7 PreAmp connected to a high current B&K, the wrong sequence would give me big thump. But not when corrected "sequenced". So even if it is "inherent" (with the B&K), I can tame the beast by following the sequence.
Never happened with tube amps as well. {Bakit nga ba?} At least the ones that I had/have. Sa tubes, iba naman. Pag wrong sequence, there is an occassional humm.
But be that as it may, you other post mentions -

Since this seems to be a design compromise, probably the more important question would be - how damaging are these thumps anyways? Or are they a mere irritation?
For example, the preceding post seeks to modify the input cap presumably to get better lows (which is the T-Amps Achilles heel; really thin compared to a 8W PP or a SE 9W). Assuming that one really likes to max out lower frequency response, will such modders just have to live with the thump and know that "it isn't damaging anyways" or are we substituting better/lower bass extension for accelerated/increased equipment degradation?
Thanks in advance :)

move the speakers closer to the wall?
In your excellent setup Oweidah, my untrained ears heard no bass weakness from your t-amp. Galing nga eh.
To ride your inquiry to the forum gurus, what are the best non-botique caps to substitute auricaps with?
thanks
-
mark,
sir dohbert had mentioned using a generic polypropelenes costing around 150 pesos. if my memory serves me right, he said it looks like an auricap daw. maybe he can shed more info about this non-boutique cap.
-
ah. I have 3 pairs of those. Thanks. :)
di ko lang makabit sa takot. hehe
-
tnx for your replies sirs gnew & markmlists.
mark, close to wall na speaker ko kaya plug-in na front port.
DEEP bass may be the sonic impact t-amp's achilles heel but as per my experience, the t-amp has DECENT enough (tight controlled bass as long as its not pushed to the limit) esp. if used on a biamp/biwired setup. im using b&w602s2 and have also used b&w601s2 and wharfedale diamond 9.1. yes it cant deliver nadc320bee's deep tight controlled bass on eagles' hfo hotel california and bonjovi's blaze of glory's 5thminute mark drums, but its MIDRANGE AND HF excellence & superiority made me decide to stick with the stock s.i. t-amp. yes, i wanna improve bass response but i hesitate coz it might have a degrading effect on the mids & hf. can compensate naman with a subwoofer pag talagang bitin pa esp sa movies.
just sharing my mameras p0. ;D

ah. I have 3 pairs of those. Thanks. :)

sirs,
will t-amp tweak to improve bass response affect the tripath chip in terms of heat generated? baka kailanganin na ng heatsink /fan?
tia :)

Use polypropelene input caps, axial sya na pabilog, parang auricaps. ok sya, pero removed it narin. Nakakita na ako ng maraming ganun sa Golden Mars. Those exact caps I've seen were used as stock caps for DACs na made in China, yan din ata yung gamit sa Zhalou if I'm not mistaken. I'm using the caps I posted sa buy and sell, gawang germany, bought it from HK, ERO brand. Mas maganda tumunog itong mga ito, pero mahal nga lang. Napakinggan narin ni john547 nung dumaan sya ng bahay to pick up some stuff na pinabili nya. As compared to the old polypropele caps I'm using, the old ones sounded veiled, parang tinatakpan ng tela yung speakers, although detail is there, not as airyas the EROs. So if you're finding your setup to be bright and tiring to listen to, I suggest you use those china made polypropelenes to tame the sound a bit.
As regards sir Oweidah's question, replacing the input caps won't affect the chip, still, I suggest using heatsinks on the chip, dahil nga yung mga bagong SI amps ngayon, wala na yung solder blob sa ibaba to help dissipate the heat. Like my first posts before, what you're hearing is bass around 100hz, it seems to be deep, but I assure you the SI can do better than that with bigger input caps, use 2.2-4.7uf, then based on the computation, in relation to the input resistors, the rolloff will begin at 5hz or so.
Weng, from what I read in yer posts, you're planning on using the SI for mids and highs then the Charlize for the bass? Na-compare mo na sila tumunog separately? Si charlize palang kasi malayo na and ganda sa SI, pero pag hinaluan mo ng SI, iiba ang character ng setup and I feel, baka di gaganda yung playback vis-a-vis only having the Charlize produce the entire frequency range. Medyo tunog compressed, para sa akin, yung SI, not as open as Charlize or amp6. Soundstage palang and separation ng tunog malayo na, so pag ginamitan mo ng SI, bka di gumanda ang output. Hope you can prove me wrong on that though.
-
dohbert,
i'm using the charlize to power the LF and SI to power the HF of a B&W600i bookshelf (bi-amp). masisira ba ang overall output kahit tweeter lang ang pinatakbo ng SI?
di ko masyadong na compare ang 2 t-amps alone kasi tinamad na ako ;D. marami pang weakest link sa setup ko. wala akong matinong IC at speaker wires. isang 5.2A SMPS lang din ang gamit ko for both amps, kakayanin kaya nito ang 2 amps? in terms of loudness mas malakas ang charlize pero soundtage, imaging & etc. halos parehas lang sa pandinig ko. i may be wrong coz i don't have a trained ears and haven't heard a well configured setup yet. sandali ko lang din test ang SI alone.
i am using pala a small fan to cool the tripath chip. 1 fan for each amp. la akong mahanap na maliit na heatsink kaya fan nalang kinabit ko. mura lang naman ang fan, 75 pesos each.

-
based on my experience,pwede rin na yung input caps lang ang palitan, at least two parts lang ang mawawala.
GneW: have you tried adding a stiffenner cap sa SMPS mo ? regarding c10, definitely kailangang palitan yan, power supply cap yan.

hi,
hey c'mon, arguing is healthy - keeps the mind working. ;D it just seems that most huge amps have some added protection for the speakers... after all if you have busted speakers, how will you hear the sound? ;D How damaging is it? that is a good question, but in the case of Charlize it may just be an exercise for your drivers. ;D
the design compromise has already been dealt with by the designers and engineers at Tripath - it's just human hipocracy to push something to the limit when we all know it's boundaries. ;D
now, comparing a tripath based amp to a tube SET is a bit unfair, Tripath chips processes the signal unlike tubes where it's kept simple. let me put it this way - I'll have a Tripath amp in the summertime but when the rain comes... I'll rather spend cold nights with a tube SET or PP. ;D ;D ;D just a moment when you can have the best of both worlds huh? ;D
oh by the way... since you are interested in compromises like more bass but don't want the thump then there is an old trick that would lower the rolloff without changing your input caps - errr... sorry, trade secret man. ;D ;D ;D ;D ;D ;D ;D

sir jojoD,
magkano po ang tranny na AC-DC 12v for T-amp? pede ba magpasadya ng 220AC in 12VDC out 3A? or meron pong nabibili gawa na nito? saka saan po pede makabili?
pwede magpasadya ng regulated psu for t-amp. meron din naman nabibili not sure lang kung safe para sa t-amp or charlize pero madami dito sa raon bumili i think less than 800 pesos. ask mo na lang kung buhay pa yun t-amp. ;D ;D ;D
dami sa ace hardware, true value, sm workshop etc. or syempre sa Raon. :)

Hanns,
ever since jan06 ive been using zebra regulated power supply 13.8v/6amperes. dalawang t-amps nakakabit- isa sa cigarette lighter socket at yung isa sa binding post (red/black). no problems encountered.
measured voltage@ the store wen i bought it=13.2v
measured voltage dito while both t-amps in operation=13.2v
bought @radiocom/andelnes raon cor. f.torres for 850pesos.
i think ace sells it for 1.2k? power cord also available 60pesos
if ur a diyr, try smps @ alexan.dami nila doon 1k up depende sa specs.
take the t-amp plunge....NOW NA! ;D ;D ;D
-
based on my experience,pwede rin na yung input caps lang ang palitan, at least two parts lang ang mawawala.
GneW: have you tried adding a stiffenner cap sa SMPS mo ? regarding c10, definitely kailangang palitan yan, power supply cap yan.
di ko pa na try lagyan, kasi sabi nila may SLOW epek raw. meron akong 6800uF cap, masubukan nga mamaya ;)

sir oweidah, tinawagan ko si John kahapon mabait na hahaha! :D
by the way I got this two converters from my fathers audio stock room, may mga tube at SS amps siya dun pero mostly mukhang hindi na gagana pa.
(http://i32.photobucket.com/albums/d16/hanns76/Kolinaudiocom.jpg)
anyways the converters brands are audiocom and Kolin, yung audiocom seems to be in very bad shape but after testing it mukhang okey pa naman, heres what it looks like;
Ngek! :P

Im planning to DIY this to install sa chassis for the T-amp’s power supply... still designing a good chassis though. papasadya kasi ako sa metal fabricator dito sa Edsa Pasay. Balak ko sana lagyan ng wood side panels parang ala tube chassis look a like hehehe! At least hindi na ako bibili pa ng power supply…
-
uy another diyr in the making!
JeDi master meet hannsolo ;D
let your creative juice flow! design ala krell ba?
adv.congrats sir hanns :)

wood panel is from a chopping board sold sa supermarket. ipa varnish ko pa to and will glue to the sidings of the chassis using silicon.
installed a fan for the SI chip. 2 fans altogether to cool the chips. very quite naman.

hanz/markmlist,
thanks for the compliment. nagpapasalamat din ako sa mga tulong ng pdvd members lalo na kay dohbert at oweidah sa pagbuo ng t-amp ko. at last, naisara ko na ang top cover. input cap mod naman sa susunod pagmakakuha ng auricap.

hi,
hey c'mon, arguing is healthy - keeps the mind working. ;D
Oh I think you know that I don't mind arguing. Just didn't mean to or belabor that point. ;)
the design compromise has already been dealt with by the designers and engineers at Tripath - it's just human hipocracy to push something to the limit when we all know it's boundaries. ;D
My point exactly. Its not a bad product. Certainly doesn't need repeated validation for those who "took the plunge". Even probably gives the greatest bang for the buck for the audio hobbyist. And I don't have any intentions in wishing rain in anyone's parade.
But since this is a review thread, I just want to point out that it does have its limitations - which might not be apparent when not compared side by side with other amps. For some, they might not even miss fuller, lower bass - if all their listening is done with the T-Amp. Might even be the "right" or "reference" sound for some if they listen to it long enough. But when you start doing A-B comparisons, ibang kwento na yun. And I certainly won't espouse not comparing it with others as some find joy in that. Its improtant in fact when deciding on gear acquisition.
But then again, siguro nga, ignorance is bliss. One certainly doesn't miss what one has not tried, or in this case - heard. Thus, either stay away from other amps or chant the mantra that "this is a $32 dollar product and it sounds better than anything near its price range' and one should live happilly ever after ... in self-exclusion. :) 8)
now, comparing a tripath based amp to a tube SET is a bit unfair, Tripath chips processes the signal unlike tubes where it's kept simple.
But isn't that how real world reviews are done (which is the subject in this thread) - by comparing it with reference gear? Sa low wattage tube amps naman i-tinapat ah. ;D
Kidding aside, I agree that thay they are completely different animals and are in completely different price points. Note that I did not deliberately chose those amps to compare it with. Just so happened that those were the ones on hand (on the rack) and my observation that the unmodded T-amp sounds thin when directly compared to 9W single ended or 8w PP tubes remain valid.
let me put it this way - I'll have a Tripath amp in the summertime but when the rain comes... I'll rather spend cold nights with a tube SET or PP. ;D ;D ;D just a moment when you can have the best of both worlds huh? ;D
Exactamento. Same as you, ditching other gear(s) for this is unlikely. And it can perform some chores well: For watching TV, fine. Ambient/background music duties - ok; For my nieces and baby :) - pwede na rin. Perfect medium for a DIY project as well. But for critical listening, serious relaxation or those cool nights with warm companion(s) - I'd probably hook up something else.
In sum, as an addition, experiment or project - yes. As a permanent substitute, well ... tweak mo muna and we'll see ... ;D :D ;D
Cheers and Happy Listening!

Bai, naghahanda ka na yata sa t-amp of the year award ah :)
mas masaya ako, yung simpleng chassis ng raon eh nagawang first-class ang dating but more impt. yung tunog ni charlize at pavarotti-amp...for good na ba yan? ;D

sir ccc,
its a simple case of "different folks, different strokes"
choose among choconut, toblerone, m&m, hersheys, cadbury etc?

Parang marketing hype ba ang dating? ::)
;D ;D ;D
I didn't compare it to a tube amp since it's way beyond the budget realm, but as I said, it's summertime now. 8)
For it's price, I have to say it's a very good performer.

sir ccc,
pls correct me if im wrong, forbes magazine, tnt-audio, 6moons audio karma guys etc didnt compare the stock t-amp to $32 to $100 amps. kaya nga sumikat eto eh kasi ang tinapat at natapatan sa performance according to those guys ay produkto na di hamak eh mas mahal. ;D
t-amp giant killer gaya ng nad3020.
bakit sumikat ang nad3020 nung 1979? eto excerpt sa audio critic-summer/fall/yearend issue- we review a $175 int.amp that sounds a great deal cleaner and more like music than many preamp/power amp combi costing $2000 and more.

korek. a $32 amp compared to a $1k amp (even if it only performs 60% of the latter amp) is still a no-brainer acquisition. this make an owner of a $1k amp cry :'(.

Hi-fi technology turns to smaller, cheaper chip-based operation
1/3/2006 8:01:00 AM
Source : Business World
DAVAO CITY -- Within five years, the high-fidelity audio industry would be shifting to smaller, lighter, and inexpensive electronics, specifically in the case of stereo and multi-channel amplifiers.
Electronic chips developed in recent years that are capable of producing audiophile-grade sound would eventually put aside high-priced amplifiers into vintage category.
This breakthrough has taken root among electronic do-it-yourself enthusiasts and, in a couple of years, would likely be applied in consumer electronics produced locally.
Since early last year, audiophiles have tested and modified their sonic impact tripath amplifiers, the first commercially available audiophile-grade chip-based hi-fi gear brought in mostly through online sources.
The first generation sonic impact T-amp is small, weighs just a few grams without the batteries, with cheap plastic casing and sold for as low as $20 from e-cost, a United States online retail site.
My two units, which arrived in Davao sometime in April, were bought through Amazon.com and cost an average of P2,500 apiece including forwarding charges.
A good number of Manila-based audio enthusiasts, however, got their units earlier, with the majority applying modifications such as changing the capacitors, improving the connectors, and installing a new potentiometer, or volume control knob in layman’s terms.
Many went for better-looking amplifier housing -- handsomely sculpted wood or transparent glass -- which do not result in sonic improvement but certainly attracts both enthusiasts and non-enthusiasts alike.
The sonic impact T-amp is rated at an average output of eight watts per channel at eight ohms, or 15 watts per channel at four ohms, an output at par with many tube amplifiers.
That rating is adequate for normal use and could even meet the demands of dynamic chamber music at loud volume in a typical room of, say, 20 square meters, provided efficient speakers are used.
Efficient reproducers mean those rated at 90 decibels at one meter listening distance and at one-watt amplifier output.
Since the amplifier’s usual electronic components are shrunk into a small chip -- the Tripath TA2024 -- less than one square inch in size, heat sinks are no longer needed.
Efficiency also improves with the signal travelling a shorter path compared with traditional amplifiers. With low output and a new amplifier topology, power is optimized translated to lower consumption without sacrificing sonic quality.
The T-amp needs a separate power supply, though, since it was originally aimed at the mobile audio market.
It operates using eight penlight batteries, which could last several hours of continuous playing depending on preferred loudness level.
Without the batteries, it needs a regulated 12-volt power supply converter to be plugged into the standard 240-volt power line.
The converter rating should preferably be at three amperes to maximize the amplifier’s rated output.
Such preference is derived using the general formula of voltage multiplied by amperage is equal to output in watts, in this case 36 watts or slightly over the 30 watts total maximum output of the unit.
Initially, local audiophiles claimed it is best to hook the T-amp to a 12-volt lead acid battery to perform best, but in my experience, using a 12-volt regulated converter does not result in sonic degradation.
This is confirmed by latest observation among foreign audiophiles as per posts in audio discussion fora. Since I have two units, one has a regulated 12-volt supply and the other a 13.6-volt converter, which some listeners in the US said results in better low frequency response.
On the first day I received my two T-amps, I tested one unit against a 30-kilogram (240 watts per channel at 4 ohms) Sansui AU-XII amplifier, originally priced at ¥275,000 in 1983.
I arranged them to appear as if I was comparing the Sansui with another amplifier, an Accuphase E-302 (180 watts per channel at four ohms) using similar sounding speakers: ElectroVoice Interface A and Denon SC-104.
My two children who came in from school had common observation: there was no difference at all when the volume of the two units were at room level.
Increasing the volume several notches higher, the children said the Sansui was slightly better sounding, not knowing it was actually a small 15-watt T-class amplifier not the Accuphase, which was compared side by side with the Sansui.
My wife who came in later said even at high volume, the sound quality from the two amplifiers was the same. Later, they were surprised to find the one pitted against the Sansui was a small amplifier that looks more like a child’s toy.
In the succeeding days, friends who would visit me were also amazed by the T-amp’s performance considering they were used to hearing only monster amplifiers.
In my opinion, the sonic impact T-amp’s sound is significantly superior compared with entry- to mid-level amplifiers, whether new production or vintage types.
Its sonic character could be described as in between the solid state’s fast, clinical response and the tube’s sweet and gradual sonic decay.
While it puts out clean and pleasing sound, the drawback is in reproducing the dynamics required by some classical and show-off pieces at loud volume.
A listener into rock, jazz or the usual popular music categories would be happy with this amplifier, especially when hooked to mega-loud performers from Klipsch, Altec Lansing, JBL, ElectroVoice, or Cerwin Vega.
By this year, higher-powered amplifiers using newer Tripath chips would likely achieve what the monster vintage amplifiers -- those with continuous outputs of at least 200 watts per channel -- could do.
The Tripath chip’s ascent as an audiophile-grade amplifier component started last year when a San Diego, California-firm sonic impact technologies marketed its Tripath-driven amplifiers aimed at the mp3 player market, specifically users of Apple iPods.
Some early buyers accidentally hooked their small plastic toys to larger speakers and the rest is sheer serendipity.
Last January, TNT Audio , Europe’s leading audiophile Website, reviewed sonic impact T-amp and found its performance comparable with solid state and tube-based amplifiers costing thousands of dollars. That review resulted in a sudden demand surge causing a temporary supply shortage.
Hundreds of local audio enthusiasts were among the first wave of T-amp buyers early last year with some enterprising groups accepting advanced orders in Manila at P3,500 per unit.
A few realized they could buy cheaper and went straight to online distributors.
That costs less than P2,500 per unit, coursed through a local forwarder, with delivery time from one to two weeks.
Acquiring the original sonic impact T-amp at less than $30 nowadays, however, could be difficult after the company introduced recently a revised version of the original amplifier now priced at $139 P7,367 at $1:P53) per unit.
Except for a better-looking case and improved connectors, all other specifications of the new model are the same as the old unit.
Dr. Adya Tripathi, the Indo-American engineer behind the Tripath chips noted as far back as 2003 that chip-based amplifier technology would dominate the consumer electronics subsector before the end of this decade.
Mr. Tripathi’s company, Tripath Technologies, Inc. based in San Jose, California, started operating in the mid-1990s.
The latest feedback indicates the price of Tripath chips has fallen from over $10 (P530) each for a low-powered amp a couple of years back, to less than $5 (P265) each now for high-powered amps.
The latest of the company’s amplifier chips puts out 400 watts output and designed primarily for subwoofer application. BY HERNANI P. de LEON, Mindanao Bureau Chief

jojod: "hindi, kaya ng bulok na owner jeep ko yan kotse mo kahit upgraded pa yan - pag nagkataon 2TG na naka twin-side lang katapat mo!."
civic: "basta! malabo ka umabot sa B16 engine ko!"
jojod: "mas mabuti pa siguro subukan na lang natin para malaman natin kung alin mas matulin, pag natalo kita akin na yan girlfriend mo!"
civic: (ask's her girlfriend for a while) " CALL!"
after 3 runs I went home with a new friend. ;D ;D ;D

weng,
kaya nagagalit si misis mo kasi pati chopping board niyo sa kusina kinabit mo sa amp mo eh!
;D ;D ;D
ganda bro, congrats master GneW!

It's not bad yes, but it does have it's limitations and that is it's weakness. Most destroyed units I have checked were mostly due to too much "pushing" to the limits. ;D
Kaya nga kailangan ikaw ang nag tweak nito ;)
-
sa totoo lang muntik ko na talagang ikabit ang chopping board sa kusina. tinuro nalang ni mrs sakin kung saan nya nabili kaya harurot kaagad ako sa supermarket para matapos ng tong kakatweak ko ;D. i need na to relax and enjoy the music.
sir jojo, thanks. ikaw ang tunay na master. madami ka na yatang nai-uwing girlfriend kung isama pa ang mga diy amps mo in comparison with the $1K amps ;D
-
hanns,
the moral of the story is that if you are happy with your civic, then be at peace with it. don't push it, know it's boundaries and limits. before you brag what's under your hood to an ugly as hell old school setup owner type jeep, it is wise to learn and compare it yourself. a souped up civic is a bad boy - at the hands of a pro it can ride like the wind, but at the hands of a weekend warrior who only knows a thing or two and races with his mouth rather than his mind - I think we all know who will eat dust. ;D
and next time, know your opponent's engine before betting your girlfriend. ;)
-
Kaya nga kailangan ikaw ang nag tweak nito ;)
all of them are stock! 100% original - my guess is that the owners weren't able to match good speakers and so the amps were driven to their deaths. :(

hindi naman, oks yan kahit 4 ohms, mas mainit lang. but since you have fans already then you have nothing to worry about. just don't push them amps to their limits. ;)

Chief Oweidah,
I usually read the reviews before making a purchase. After that, I don't look back nor try to seek repeated validation to justify my purchase. I merely conduct my own review, in my own environment, primarily by comparing it with relatively comparable gear I may have on hand. And in my direct A-B comparison, ganun nga - as stock, it does not go as low as compared with what I had at that time, everthing else remaining constant.
And since this a "user reviews" thread, I merely posted what was simply my review - which I will not bilge nor color just because of what I read in some magazine or website.
Everyone has an opinion and each should be respected. If the reviews of others don't jive with mine, then so be it. If hype got the better of me, then so be it. If it doesn't match with my gear, then so be it. If I'm not happy with a product, then so be it. If I bought impulsively - sell immediately before the wife finds out! ;D Ganun lang talaga. The journey requires a lot of experimentation. Note that I do not regret purchasing the TAmps. I'm just putting it in its proper place in my scheme of things.
But the important thing is that sharing of opinions in this forum should be beneficial. For example, the whole exercise showed that if bass is important for a prospective TAmp buyer, then a direct comparison between his short listed amps would be useful. And as JojoD has just posted(death due to overuse), the Tamp should be matched well and used within its limits. And I believe that knowing what those limits are and letting other members of this forum - particularly those in contemplation of purchase - know of such limitation would be beneficial.
As to the venerable Sandawa's review, it also concludes in an opinion and I believe that he has observed a similar TAmp limitation -
xxx
In my opinion, the sonic impact T-amp’s sound is significantly superior compared with entry- to mid-level amplifiers, whether new production or vintage types.
xxx
While it puts out clean and pleasing sound, the drawback is in reproducing the dynamics required by some classical and show-off pieces at loud volume.
As to Sandawa and the foreign reviewers, their generally favorable review doesn't mean that the product is without limitations. Moreover, none of them stated that they will ditch their current gear to permanently replace it with the Tamp. Its generally good, but I don't think it will be the only amp in their portfolio.
Hope this puts (the review) in its proper perspective. :)

sir ccc,
as ive said...different folks, different strokes.
though may kanya-kanya tayong biases at preference, hinahangaan ko pa rin yung "calling a spade, a spade" tell it like it is, kesa sa puro papuri o paninira to promote one's interest. the t-amp has its share of negative reviews and opinions that were posted in other fora. for some, the t-amp aint just their cup of tea.
i've wholeheartedly agreed that the sonic impact's weakness is in the reproduction of the LF (100hz) though in my case, i've accepted the trade-off less bass for excellent mids and highs.
and i've always highlighted t-amp's limitations, when asked by those who wanna take the t-amp plunge.
i posted those links to past reviews in reaction to this part of your review-
Thus, either stay away from other amps or chant the mantra that "this is a $32 dollar product and it sounds better than anything near its price range' and one should live happilly ever after ... in self-exclusion.
those audiophiles also did their reviews in the real world and they have reference systems just like you. i didnt see them compare t-amp with amps from nad rotel etc.,or anything near its price range. eh sino bibili ng s.i.t-amp kung sa entry-level lang ang tinatapatan nya? tsong, nakuha ng t-amp ang kiliti nung mga taga tnt-audio 6moons atbp kaya nagkaroon ng bandwagon effect at na-feature tuloy sa forbes magazine.
*
btw,
i agree with some opinions posted at other site's forum na ung ibang audiophiles hindi lang matanggap na isang "laruan" gaya ng t-amp lang pala ang tumapat sa libong dolyares halaga na gears nila. y? eh kasi, now, ordinary people like me will have a chance to own and hear a cheap-charlie gear that sounds better than some "audiofool-hyped and marketed high fidelity gears".
;D
-
sir ccc,
lets all lighten up, enjoy the summer heat!
btw, have you tried the t-amp sa car audio setup?
cheers! ;D
-
I think the so-called problem of dynamics is not really a problem of the amp or the technology itself, kailangan lang nga talaga ng magandang synergy with the speakers used. Try using it with really efficient single driver like lowthers or corals, lalabas ang dynamics dyan. Heck, kahit na nga multi-way speaker basta at least 92db pataas kakayanin na yung dynamics na supposedly hindi naririnig ng ibang reviewers. Just my 2 cents. Kanya-kanyang preference lang talaga I guess. So far masaya na ako sa amp6 and charlize ko. ;D Yung SI ginamit ko pang ps2 nalang, hehehe ;)
-
This amp is excellent on its price range! Comparing to my Cambridge Audio Amp, well I can say this is not match for a comparison.
My initial criteria is for "Tonal Balance" & "Weight", you can never expect a 10 second car to a Honda Civic alone not even the SiR Version. ::)
-
hanns,
the moral of the story is that if you are happy with your civic, then be at peace with it. don't push it, know it's boundaries and limits. before you brag what's under your hood to an ugly as hell old school setup owner type jeep, it is wise to learn and compare it yourself. a souped up civic is a bad boy - at the hands of a pro it can ride like the wind, but at the hands of a weekend warrior who only knows a thing or two and races with his mouth rather than his mind - I think we all know who will eat dust. ;D
and next time, know your opponent's engine before betting your girlfriend. ;)
saludo ako sayo boss hehehe! naka ethanol yata yung owner type jeep mo eh? ;D ;D ;D
sana gumana yung t-amp sa lumang converter ko. ill just try to housed it in another chassis pero no major tweaking... ;)
-
parang ganito lang yan $32 at $1K...
(somewhere at around 3AM)
civic: "pare, hindi ka uubra dito sa civic ko, iiwanan ko yan old school engine ng jeep mo!"
jojod: "hindi, kaya ko yan basta quarter-mile lang!"
civic: "hindi ka nga mananalo sa akin! naka upgrade ang chip ng computer box ko, naka iceman intake, headers, eck eck ako no!"
jojod: "hindi, kaya ng bulok na owner jeep ko yan kotse mo kahit upgraded pa yan - pag nagkataon 2TG na naka twin-side lang katapat mo!."
civic: "basta! malabo ka umabot sa B16 engine ko!"
jojod: "mas mabuti pa siguro subukan na lang natin para malaman natin kung alin mas matulin, pag natalo kita akin na yan girlfriend mo!"
civic: (ask's her girlfriend for a while) " CALL!"
after 3 runs I went home with a new friend. ;D ;D ;D
LOL, Nakakrelate ako dahil I used to have a Civic modified with a v16 engine years ago. Pero di ko naman pinang pusta ang GF ko nun. ;D

Hi guys,
sobrang busy ko kanina kaya eto magpapalamig muna ako sa harap ng pc...
Hanns para sa iyo ito... maybe OT so shoot me... in the leg please. pero baka makatulong sa pagbili mo na amp.
I was in a local Starbucks sipping this pretty expensive espreso and watching girls walk by when all of a sudden this flashy white Mitsu EVO VIII with this AirForce spoiler sticking out it's back, a set of shiny 17" wheels with matching Michellin tires parked in front. Some of the girls immediately came to see this nice car but after awhile, I heard this screaming/howling sound and I said to myself - "wow, only an engine with a throttle horn assembly can sound like that!" - and so low and behold... a Porche Carrera came and parked beside the EVO, all I can hear after that were the oooohhhhss and aaahhhhhsss from the girls. ;D ;D ;D

Last year at sensible audio i brought a pair of dadm100 flying mole amplifiers to use for demoing a pair of speakers i have been eyeing...well lo and behold there was a big krell amplifier being set up with an audio research preamp and a pair of dynaudio floorstanders.
After about 30 minutes listening to the setup i requested if i can try out the speakers (harbeth hl-pe3s) with the flying moles. The combo was very nice and big sounding, there were two customers who walked in and was under the impression that the amp being used was the krell and the speakers were the dynaudio floorstanders and gave a puzzled look when they were told otherwise 8)
then again the place was small and the krell setup was probably overkill, lesson learned though and experienced is equipment used in the proper room or matched accordingly can give very good results.

If I use a pre-amp with a T-amp, will i no longer need to upgrade my t-amp's cap?
Thanks.

You still need to do the upgrades. Even if you use a preamp stage, once it gets to the amp stage of the SI, it's inherent limitations will manifest themselves, like low bass response, etc, even if your source or preamps stage can do 5hz.
-
Thanks sir DOHbert..
-
try it straight up first with your preamp before making any upgrades. sometimes the simpliest solution is the best solution.
if it doesn't work then that's the time when we gear up for technicalities.

What power supply you used for your SI amp.
Please recommend me, also 'yung location po saan nakakabili.

Popular choice is the Zebra Brand. 1 amp, 3 amps and 6 amp versions.
The 6 Amp version has enough power for 3 simultaneous T-amp connections. Available in (Ace hardware SM malls)-P1200 and other Raon stores (P900). Handyman also carries an in-house brand na P599(?). SMPS from Alexan can be used too. Zebra is great in my limited experience.
Excellent Custom Power supply also available from tech guru JojoD .
Trivia: Kaya ng Zebra 6amp version ang 10 T-amps. Wag lang i-o-on. :) But seriously, maganda.

Master Bon, here's one pic for the meantime of Charlize in action. Ang liwanag nung LED sir! Compare the intensity with the display of my Philips CDC 468. I brought it to the session of PinoyDVD members along Commonwealth last Saturday and all the attendees were amazed by it's performance and your workmanship ;D. Had a brief comparison with Oweidah's Sonic Impact T-amp hooked up to his AR sound enhancer. Mas pronounced ang effect nung AR when used with Charlize. As for comparing sonic quality, kulang sa oras... Oweidah had to leave early. And maybe Charlize needs some more break in. We used a vintage Pioneer disc changer (forgot to get the model), through a Kones tube pre-amp, and finally a pair of DIY single driver bookshelf speakers by Nirvblkr. The session was in an open garage; not really the most ideal conditions but Charlize didn't show signs of strain at all. We also tried out a pair of vintage Realistic two way speakers. Kayang-kaya pa din and lalong lumabas ung bass sa "Use Me" track of Patricia Barber's "Companion" (http://i34.photobucket.com/albums/d106/mykatjak/Music/CompanionPatriciaBarber.jpg) album. Btw, we used Oweidah's diy Belden RG6 interconnects and QED speaker cables. Thank you very much sir for leaving these with us even though you had to leave early.
Hope to take more pics soon as promised Bon. Nagloko lang kasi ung gamit kong memory card and the pictures I took at the session disappeard :-[. I guess I have to buy a new card and a bigger capacity one at that. Saka pasensya kung medyo malabo ang photo. I didn't use flash kasi because it made the image pale and hindi makita ung blue led. Need to practice my photo taking skills too. This picture doesn't do justice to your craftmanship sir.
Hindi ako marunong sumulat ng audio review. All I can say is Charlize is very balanced and clear sounding. I'm very happy with this amp because it produces the sound I like for the material I most often listen to. Which is really what it's all about anyway.

I got my hands wet last night when I was able to receive from my brother a T-amp. I tested it with my Coral Flat-10 with 96dB sensitivity. Shown below is one of the baffle I temporarily made for the speaker. The one shown has some repair in the cone, the other one has none. I still have 1 pair unused, and the other pair in a national vintage box paired with a Pioneer integrated.
(http://usera.imagecave.com/aHobbit/coral10.jpg)
I used a relaxing remixes
The T-amp uses standard AA batteries due I have no time for further tweaking and SMPS/regulated PSU preparation.
With the coral (which I do not want with my Yamaha RX-V630) sounds very good, the bass is full and low, and the high are so smooth. It looks like my Coral finds its match in T-amp. I am now designing my final baffle to the coral after I heard it sing with T-amp.
We tested other music like classical and standard contemporary. Acoustic materials (and vocals) sounds very good with the tandem. Contemporaries and orchestra is somewhat mixed. I will try to make further report on other type of music and listening impressions. I dont think I will tweak the stock amp. With the battery, it already sound very good to me with the coral.

mga master im planning to buy na sana ngayong katapusan. baka naman meron pweding magpahiram ng t-1mp kahit 1 day lang test ko lang sa mga speakers ko na high sessitivity. baka kasi magandahan ako eh makabili na nga... ;D

pwede yan joey, SMPS type yan pc psu. some use a load resistor on pc psu so it is fooled to have a load. as for the sonics and noise floor, better ask them users of SMPS type psu with their digital amps.

sir jojod,
ano po'ng noise ang narinig nyo using an smps? wala akong marinig sa smps ko. this is the way i tested it, pls correct nalang kung mali ang paraan.
1. pause cdp
2. amp at max volume as i did not have a pot at that time.
3. placed my ear in front of the speakers
dead silent talaga ang speakers.
i increased the smps voltage to 13.2v just to give a little oomph but again ganun parin, no hiss or hum. i'll look for a regulated linear psu para ma compare. ayoko ng gamitin yung sa vhf radio namin dahil nasa 14.8v yon.

Hi Gnew,
I'm not sure if my PS came from Alexan. Bon sourced it from John5479. Initially we were planning on a SLA battery source but I changed my mind because I wanted easy portability; the battery would have required an external charger. Total cost would have also exceeded my budget :P On the other hand it would have provided pure DC voltage without the noise generated by a SMPS. Personally, I'm happy with my decision because I met my objectives of least cost and portability. And, to tell you the truth, I can't hear any noise. Maybe it's because of my advanced years ;D. Or maybe I just don't know how to test/listen for it.
Btw, how did you get your PS to output 13.2v? Is there any advantage to doing that?
-
been wanting to, but afraid to use my old Enermax brand PC PSU because its +12V rail is rated at 15A! Will using
this high ampere fry the Charlize?

your smps is from alexan (exactly the same as mine) as john mentioned it to me before. there is a small trimmer (variable resistor=tama ba?) near the output side. pihitin mo lang yan dahan-dahan (with a small screw driver) with the output hooked up to a multimeter. you can adjust it to a single decimal point in accuracy. make sure to remove the leads to ur amp before doing it.
as to the advantage using higher voltage, mas louder ng konti sa pandinig ko. the gurus can englighten us here regarding this issue on the sonic side.

sir ding,
tried my charlize with a 15A Daiwa brand VHF radio regulated linear psu. ok lang sya at naitanong ko pa to kay master jojod. di ko nalang ginawang permanent supply dahil ang regulation niya is out of range. from 13.8v naging 14.4 na most of the time kaya mainit ang tripath chip.

-
ding45,
there can be a problem with that psu since most SMPS (especially those with high current capabilities) increases output voltage when there is no load. since a digital amp would present a marginal load for your psu, it may breach the amp's supply limit. I strongly suggest that you check output voltage and monitor it while you integrate your amp to that psu.
hindi ka naman siguro manghihinayang diyan sa Enermax mo kung masusunog niyan si Charlize? ;)

use a scope.
you won't hear it like that, you can only hear it (see in a scope) when your amp is conducting, of course it would be dead silent because your amp is not conducting. the positive and negative effects of a power supply in an amplifier can only be percieved during operation.

Update on my Charlize. Been using it with a Luxman C-03 preamp for an estimated 20 hours now. A long way to go to reach Yeo's recommended 100 hours break in period!
(http://i34.photobucket.com/albums/d106/mykatjak/Audio%20gears/Lefttopless1.jpg)
Inside view. Btw, I don't hear any thump at all when powering up. What I do is: turn to first position, wait three seconds, turn to second (full on) position. I leave the volume knob turned to 1 o'clock position permanently. At that setting I only have to turn the Luxman's volume knob to the 9 o'clock position usually to achieve my normal listening level. My listening area is about 22 sq. meters and it's not totally enclosed since it's the living room and there's an open archway that leads to the dining room. Luckily my neighborhood is very quiet at night (something I really, really like :)) so there's no need to play loud. Something that surprised me was the presence of good, clean bass. I was prepared to sacrifice this once I started using Charlize since I was used to my Sansui AU-D907X Decade. But I honestly have not noticed any difference. Unfortunately, I'm relying purely on memory in comparing the two; can't do an A-B comparison since the Sansui is in need of a check up :(. Clarity and detail, as expected, are both very good. I expect Charlize will sound even better as I reach the break in period ;D
-
hi mandrake,
just a suggestion, if you have an mp3 player or a discman, you can play tracks repeatedly for about 4 days and you'll reach your break-in period. white noise tracks can help here, just a small amount of volume will do, so it won't annoy you.
congrats and good luck on your break-in bro. :)

Thanks Jojo. And you're absolutely right! Bakit ba 'di ko naisip 'yan ??? Kaya lang sira na ung discman ko..but I do have an original Walkman (cassette) that has a tuner. Pwede na ba tuner na lang gamitin ko?

Replaced the defective 50K generic volume pot in my Charlize with a 100K Alps vol. pot...NO change noticed in sound quality but now I have to set the volume at 12 o'clock instead of the 9 o'clock on the old 50K pot to get to my normal listening level (moderate loudness). I use the Charlize (no preamp) to drive a pair of Leisure 3SE.... Is the reduction in gain normal?
-
mandrake,
Pwedeng-pwede, in fact, a tuner is what you really need! Make sure to tune it "off-band" for lots of white noise material. Then just set your amp's volume to a level that will not annoy you and leve it for 4 days and that's it. ;D

that's normal.
generic pots are generally linear types while ALPS pots (among other audiograde pots) are log types.

You can also position your speakers facing each other then wire them out of phase. This way you can turn up the volume higher.

Another good suggestion. Thank you sir. :)

Has anyone tried wiring your speakers out of sync with the Charlize... I mean instead of connecting (+) to (+), connect the (+) to the (-) terminal on the speakers? I accidentally did this and I thought I heard better HF detail but I corrected the connection at once fearing it might do harm to the amp and/or the speakers.... Makakasira ba ang ganitong baligtad na connection ng speaker wire?

the speakers will just be out of phase...
-
ding,
the speakers would still be in-phase if you reverse both channels. However, if only one channel is reversed then it would be out-of-phase and you'll have cancellation of correlating frequencies present on both channels. This would depend entirely on the program material you are playing as long as it is in stereo. Try listening to mono recordings while your speakers are out=of-phase and you'll have a bad listening day. ;D
as for safety concerns, your speakers nor your amp won't be damaged by out-of-phase signals.

mga pre baka naman pweding makahiram ng t-amp. :'( ( dalawang araw lang, sige nanaman) gusto ko sang maaudition muna bago makabili. meron nakong power supply na gagawin (diy pc psu) at speaker na on the making na rin. been reading some tweaks ng t-amp at naiintriga talaga ko sa small at afordable but heavely good reviewed t-amp. meron bang club ng t-amp user dito o asosasion? ;D baka pweding magpamember? ;D

joey,
yun t-amp ni KoYA Vens nandun pa kay Master Chief sa bundok, ask mo baka pwede at least malapit sa iyo.

recent development :
eto dati setup chain ko since acquiring t-amps feb06 :
yammy avr as preamp processor / ar tds202 / s.i. t-amps.
noticed a few weeks ago that sound was now better when ar tds is bypassed (off position) so i changed setup to => source (cd/tuner) / ar tds / yammy avr.
i think this may mean that t-amps are now fully broken-in. took 4months but ts well worth d wait!
any similar experiences?
-
what can i say? its superb! :o masyadong detalyado yung lumalabas na sound for this price range. match with Acoustic Research TDS202, sony speaker full range & mp3 player. yung ar tds202 at T-amp kasi yung nakita ko sa audiokarma.org na maganda raw imatch. tama nga sila! ;D

Have converted my spare PC PSU with 15A in the 12v rail to power Charlize...resulting
sound is better esp. in the low frequency compared to the previous 12v, 1.5A wall
adapter. Connected dummy load of 2x10 ohms resistors connected in parallel to the 5v rail. Glued the
resistors to a spare heatsink & fan to avoid overheating...... voltage reading is steady at 12V...(this modification
is a copy of what I saw in bit-tech forums)
-
well done ding!
-
congrats joey!
-
Thanks Sir Jojo, I just hope using 15A will not shorten the usefull life of the Charlize... anyway I'm
monitoring the case temp. of the Charlize and it seems the heat is the same as in using the old wall
adapter.
-
Congrats Ding...
Yung iba magkakasunod ang project-ikaw sabay sabay. Nakakabilib! :)

galing mo ding! ;D
sa susunod ikaw na gagawa ng mga gears mo! ;)

It shouldn't so don't worry. The 15A is there just for current availability, if your amp unit demands 2-3Amps then that's just what your supply would provide out of the 15A.

Thanks guys but all I know is basic soldering......BTW anyone know how to make a SPDIF to Digital/Coax cable...like to try to use my spare CDRom drive as transport and connect its digital out (two pins) to the
digital coax. input of my DD decoder/DAC. Paki post ng links kung may alam kayo pls. Sorry kung OT

the left channel of my SI t-amp is dead. the right channel is working fine. does this mean that the chip is fried?
what i have done earlier was replace C10 with a better cap. parallel the 2 input rca of the 2 t-amps to eliminate the use of Y-splitter (for bi-amping). then hooked the amps back and noticed that the left tweeter wasn't working. both channels of the other amp (charlize) are working fine.
is there any chance i can resurrect the left channel?
-
You can also position your speakers facing each other then wire them out of phase. This way you can turn up the volume higher.
Then throw a thick blanket or 2 over them for even higher volume level.

natanggal pala ang L1 sa board. siguro sa paglinis ko using a brush. sinubukan kung ikabit uli pero di kaya sa sobrang liit. dalhin ko nalang to sa cellphone technician para maikabit uli. sana gagana uli ang left channel.

I forgot to post my T-amp setup here.

sir matz,
pakita naman t-back mo para makita golden spada ni mars ;D
-
Sige I will take a picture, but I used the spades for my speakers only. Medyo hirap kasi gamitin yung spades sa T amp since I am using it now for my main HT room, so palipat lipat from T-amp to reciever + power amp. Thanks for the heads up sa spades! :)
-
easy bai, i suggest marinig mo sana fully broken-in s.i. t-amp before you tweak it. my t-amp bloomed to maturity after 4 months ;D
-
ang likot kasi ng kamay ko e ;D. anyway kung di maikabit uli ang L1 gagawin ko nalang ang mod 2 ni audio1st sa diyaudio.
(http://i11.photobucket.com/albums/a165/weng2x/th_untitled.jpg) (http://i11.photobucket.com/albums/a165/weng2x/untitled.jpg)

tama ka sir jojod, break-it na ang ginawa ko ;D. di ko pa pinaabit hanggang ngayon,wala pang oras punta sa cellshop.
anyway, suggest ni audio1st sa diyaudio na pwede daw e bridge ang L1 connection kasi filter daw to sa input. kagaya rin daw to sa "classic" mod na by pass ang filter. sana pantay ang tunog nito compared sa other channel with the L2.

got an irresistible offer from dennispm. lalong gumanda ang t-amps paired with a tube pre.
here's my poorboy setup:
(http://i11.photobucket.com/albums/a165/weng2x/setup.jpg)
B&W600i, CSI t-amps, JVC DVD (now in search for a decent CDP) and my new catch, tono preamp
btw, my SI amp is alive and kicking now. did the "stealth mod 2" using a so-so cap. was forced to use this mod as the broken L1 did not work when soldered back. this amp only feeds the tweeters so no need for premium caps to fix the bass roll-off. the t-amps volume control serves as a makeshift tone controls, bass (charlize) and treble (SI)
-
replaced the stock C10 of my SI to this.

docJ,
simple diy generic 12au7 & raon parts-based tube preamp made in china(town) binondo by andrew (not sevilla) for rene (not rivo) ;D
swerte lang ako nagbitaw si new_age ng janphilips5814a at may nos jan5963 sylvannia sa watsons @300php. ung raytheons at rca? blackplate ay kasama sa tube preamp.
i believe meron din @silverstrings. meron pa yata nos rca ge at sylvania 12au7, 5814a, at 6189 @watsons. matsu****ta @deeco and various nos tubes @southern radio supply.
konti lang ang tube sources dito so might as well get some before maubusan for the customary tube-roll :)
nakakahawa talaga ang mga t-amp/tuberos dito!!! ;D ;D ;D

dunno what circuit used. simple lang porma same dimension as decibez chassis para maipatong sa t.amp.
just upgraded to f&t filter? cap and auricaps.
yes meron daw somewhere out there..soler pala. saan banda? may tube tester sila?...TIA:)

Exactly sir, unlike SET amps, t-amps are a bit more fragile. sa SET pag medyo naihataw ng di ayos mag distort lang. sa t-amp naman nasusunog yun chip pag nasobrahan.
Kung 89db or up ang spkrs oks na oks yan sir para hindi pwersado. Sa program material naman hindi ito namimili, even plays pop and rock (though alam ko di mo type yun :)).
No problem sa questions sir, ikaw pa. :)
-
Ah okey medyo na gets ko na. Thanks
pag nag didistort yan dba garbage na yun signal na inilalabas alin masira yun chip o yun speakers?
Dun ko ikakabit sa tube preamp na ginawa mo, Yun setup para sa kapatid ko di akin.
Note: Nasira yun 3 piece altec na PC speakers kasi napalakas ata yun volume.
Many many thanks bro!........ ;D ;D ;D

yun chip ang nasisira sir, especially kapag hindi nag match sa speakers. minsan naman sa mga palpak na psu kaya bumibigay yun chip. pero na drive niyan yun 9.1 ko, di nga lang kalakasan. pair mo lang sa 89db pataas oks na ang listening level.
aprub yan dun sa tube preamp na ginawa ko sir. ;)

Can one convert a laptop psu giving out 18V to output 13.5V for the T-amp? Simple mod ba or complicated?

meron sa alexan. i'm using one, 5.2A/12volts rated, priced 1.1k. oweidah was the one who bought it for me, thanks man :).
bump its voltage up to 13v by rotating a trimmer near the output terminal. accurate ang voltage increase up to 2 decimal places using a digital multimeter. used this to power a CSI amp.
hth ;)
-
tama si rascal, hindi simple mod yan. mag diy ka ng dc-dc converter that would sink ~5v para magamit mo yan.
-
Thanks sirs aHobbit and Rascal.
kala ko puedeng dropping resistor mod lang hehe
Magbabago ang output voltage mo with respect to load kung dropping resistor. Di kaya ma-maintain nung feedback loop dahil sa existing output siya nag se-sense. Since gagamit ka ng dalawang resistor sa voltage divider mo, baka di kayanin nung unang resistor kapag mataas na load. Ang voltage divider maigi lang kung fixed load.
-
Actually, mayron na akong t-amp power supply, nanghinayang lang ako dito sa laptop ps ko dati. gawin ko nalang case ng diy filter hehe. salamat ulit.

Rony, I used 89db speakers before. Ok naman sya, kahit 1 T-amp lang ok na.
I am now using the T-amps with a 88db speaker (Mission M52 floorstander). Pangit pag isang T-amp lang. Pero pag dual T-amps. Ang ganda!
Yun nga lang, pag masyado malakas volume, nag didistort. Pero no problem since my listening room is only 12 sq m. and my music is mostly jazz , vocalz & instrumentalz. 8)

sir matzter how the tube roll for the preamp that drives the t-amps? ;D
kung may kapares yung raytheon , ge o beckman 5814a...u may wana try it.
-
Na break in na yata T-amps ko after many hrs of usage. Ang ganda talaga ng tunog.
I also changed my 12au7 from Jan Philips to Sylvania, lalo pang gumanda.
Kasing ganda (or better) nya na tumunog yung HK630 plus Rotel bi-amp combo ko. Balak ko tuloy na ibenta receiver ko at mag downgrade since pang HT na lang usage ko sa kanya.

just keeps getting better! used within its limits, dami upscale amps taob sa t-amp/tube preamp combo!

Somebody is selling me this Cerwin Vega 250-SE floorstanding speaker, 125 watts @ 6 ohms with sensitivity of 94db. Kaya ba itong patunogin ng T-amp? Pwede na ba ito sa Php 7.5K o tawaran ko pa? Guys, you know better, what's your opinion/advise? TIA

better to audition it first. of course the t-amp can drive that but up to what volume level before it distorts is the real question. if your normal listening levels are satisfied then I see no reason why you shouldn't buy it. :)

I'll try to audition this speaker tomorrow or Sunday and i'll bring with me my T-amp. Kaya lang hindi ko alam kung yung Php 7.5 k ay fair na or tawadan ko pa?

Hi all. Di ko alam kung OT but ask ko lang ano masabi nyo sa site na to http://www.41hz.com try ko sana order one of their tripath amps as my first project. Is it practical or just order and let the PROs do the assembly. TIA.

I have successfully built several of their amps and I really liked them. Amp3 is an exceptional amp for it's price. Compared to other digital amps, I liked the Amp3 better for it can really rock. 41Hz products are sold as kit so that means you have to build it from scratch. However, nothing beats the t-amp for it's simplicity - there is nothing more to build, just provide the right speakers and psu and you're off.
cheers
-
I have a Amp6 myself, with built in regulated PSU, so lalagyan mo nalang ng trafo ok na. Maganda tumunog. I ordered it when I was from the States, umabot ng 1 week delivery. Pero if you order it here, baka lampas pa ng 3 weeks. Heard someone ordered from Taiwan, 3 weeks na di pa dumarating yung kit. So verify from Jan how long the waiting time is. Tapos ang gamit nya is regular mail, insured naman, so nakakatakot pag dating dito sa atin, baka di umabot sayo. :o
-
yun chip ang nasisira sir, especially kapag hindi nag match sa speakers. minsan naman sa mga palpak na psu kaya bumibigay yun chip. pero na drive niyan yun 9.1 ko, di nga lang kalakasan. pair mo lang sa 89db pataas oks na ang listening level.
aprub yan dun sa tube preamp na ginawa ko sir. ;)
i am using a 4-ohm b&w DM600i (87db) bookshelf powered by a charlize. at near clipping volume, mainit talaga ang chip. ang smps ko pa ay naka set sa 13v. but i had installed a tiny fan (sized like an old 1 peso coin) at the back of the chip. sinubukan kung e-todo ang vol, warm lang sya. btw, my amp chassis top is unscrewed para ma monitor ko ang chip temp using my thermometer fingers ;D
kaya its "cool to be cool". quite naman ang fan, medyo may konting ugong ka lang na marinig while music is off.
peace ;)
-
bai parang pc yan ah...may smartguardian temp monitor. lagyan natin kool-fever ba yung para sa lagnat? ;D
yes yung t-amps pag ginamit ko sa wharfedale d9.1 86db/6ohms ang ganda tunog pero mas madali mag-init.
-
Thanks for the reply sir DOHbet and JojoD. Might as well try other routes then for the shipment via US siguro para safe. But if its tricky then opt to have t-amps na lang....

good for you sir GneW!
but to some who only want it to run as is (out of the box), it would truly benefit from a higher sensitivity speaker. Besides, I was talking about a t-amp. the charlize is a more "powerful" version, yes?
re your "ugong" problem, that can be remedied by isolation materials installed for your fan.
nice to know you also have a thermofinger installed. ;D human fingers really are versatile don't you agree? ;D ;D ;D

thermofinger...that's a good name for it ;)
actually may fan din ang sonic impact amp ko (remember i have a CSI amp ;D). sa SI, sideways naka blow ang fan. used the dm600i also but only for a short time (as in few days of playing music) coz i wanted to break-in the charlize first. then didn't had the chance to listen to the SI in full mode as i am always using it to power the tweets.
-
GnEW,
some of the hardcore diy'ers use a 0.5mm thick 99.99% copper sheet that's thermally bonded to the SI chip and use that as a heat-spreader to eliminate the use of fans. they say that fans can affect the sound but I don't know about that being true.
better yet, always test and trust your thermofingers. ;)
-
I already brought these speakers home last night. Tested it with my t-amp and in my opinion (the way i hear it) it sounds so sweet and the detail is very good. With the night so quite, using moderate volume of the t-amp (around 10 o'clock position) feeling ko naka-walkman ako. Low frequency is good too. I think di ako lugi sa Php 6.5K.

I simplified my life ... bought a laptop PSU with 12V output at 800. Presentable mobile high end amp? ;D No time to tinker with it at the moment :(
Bro, where did you buy this laptop PSU na may 12V output at Php 800? Baka may pics ka? TIA

is it possible to add phonostage on the t-amp? any tweaks? tnx
-
is it possible to add phonostage on the t-amp? any tweaks? tnx
yes of course. just use an outboard phonostage for that matter.
what tweaks are you reffering to?
-
mga sir,
paki review lang po kung tama ba tong ginawa ko.
the tono pre-amp i have comes with 1 pair of output. i've connected both t-amps input RCAs in parallel to eliminate the use of Y-splitter. ok lang ba to?
now, there is one pair of unused RCA on my t-amp.
will this (unused) RCA be considered also a pre-out of the tono?
will there be any issue if i hook up a subwoofer from that connection?
maraming salamat po :)
-
if the unused pair of rca is connected also in parallel to the other amp then it should be ok. impedance loading should not be a problem since the t-amp + t-amp + subwoofer should still present a relatively high impedance to your tube preamp.
-

yes sir jojoD, the 2 t-amps RCA are connected in parallel. i will try this with a sub some day.
cheers :)

weng, that should work ok.

sir juneaki, wer did u buy your cerwin vega speakers?... nag-inquire me b4 sa may distributor ng CV located at brgy. bahay toro in QC kaso la pa daw sila units for home theaters eh... mostly they are selling is for outdoor/pro speakers.... are these the v series or the e series??... maganda kasi sound quality ng CV's eh....

This is a second hand pair of Cerwin Vega 250SE which i bought from a friend. With a sensitivity of 95db (based on manual) the t-amp got no problem powering it. Tama ka, this speakers sounds so sweet and the detail is amazing. And who says that t-amp cannot produce good bass? With these speakers, t-amp produces quality low frequency sound.
-
... And who says that t-amp cannot produce good bass? ...
Huh! who said it? ??? >:(
Baka its their speakers that can not produce the good bass ;D - My 10inch coral floats the bass of T-amp! 8).
The T-amp graph really shows sloping down starting at 100Hz. But in room response of the speaker can flatten it out - so with the tweaked placement, this is not an issue to me. I dont expect my speakers to give me the 20-40Hz at their present locations, so I do not run after this freq band. My sub is in place to fill in the gap.
As for the HF, since my coral is a DIY thing, I compensated the drop in the 10kHz up with a higher-sensitivity tweeter, and balance the overall sound synergy - though I know this can not flatten the 10k up so am more into checking the mods for this 10k&up band.
he he ... off lang siguro synergy ... matching, in-room response and/or placement should be able to correct the LF deficiency :)
Congrats on a very good CV vintage... time to enjoy the music
-
OIC!!... ur very lucky to have pairs of CV's. I still remember during my early years (1985 - 90's), ang review or intro sa CV speakers is "the lowest low" tama ba me??... correct me if i'm wrong, i learned it from guiness book of world record??.. Nai-published yan b4.... anyway congrats.... and happy listening....
-
Yes you're right! the lows are really lows with CV. Sorry po mukhang OT. Anyway back to T-amp.
Guys, have you tried using your T-amp simultaneously with your receiver? I experimented on this set-up last weekend and it gave me a new experience. Using the same source (pioneer 686), i hooked the digital out to the receiver (onkyo 501) and the stereo line out to the T-amp. The sound level of the fronts (Diamond 8.3)hooked to the receiver was slightly lower than the sound of the speaker (Valdus 200) hooked with the T-amp. The receiver was set in all channel stereo and the subwoofer was on. This system works in such a way that the T-amp and the receiver compensate for each other's weaknesses. The T-amp provides the detailed highs and mids while the receiver provides the lows thru the subwoofer and the surround environment. I-try nyo at sasabihin nyo para kayong may bagong gears.

bro juneaki
congrats! ok yan experiment as you grow in this hobby. bilib ako sayo hindi ka nagpapakahon sa traditional kagawian at kaisipan sa audio. kung saan ka maligaya supportahan taka. ;D
btw nung unang panahon na wala pa ht at ang multichannel system lang ay yung mga quadrophonic systems, i tried different ways to compensate what my main speakers lacked.
using only one stereo amp/rcvr- a) i stacked two sets of speakers atop@ other; and b) i spread out my main speakers far apart and put a pair of speakers in the middle- for wider soundstage. i also tried using add-on tweeters (forgot the brand but hindi raw tweetrs naka-box na).
i suggest you try using the t-amp with a tube preamp. or if your avr has a front preamp-out feature use the avr as preamp/processor lang at t-amp as your main amp, the subwoofer will provide the needed bass.
cheers! ;D

Bro, where did you buy this laptop PSU na may 12V output at Php 800? Baka may pics ka? TIA
LAPTOP psu varies in voltage. When I went to HMR in the PC power supply section, there are lots of SMPS module there, try to check each one until you found 12V output and have it tested by the technician behind the bench. I got 12V 2.5amp - so at 8ohms, and 6 watts, it will require no less more than 2A, thus, the SMPS unit will suffice.
I selected this type kasi wala ka na gagawin and very portable, you can easily have the supply far from amp to avoid noise pick-up by amp, and you can bring it side by side with a T-amp (especially if you want to audition speakers in any shop (this is fun ;D). Kulang na lang, portable 'high end' full range para jammin' anywhere ka (any body has solutions? ;D) wag lang kalimot about the source.

HMR is a dealer of surplus items from US, right? That is why ang sabi mo ay ingat lang sa source kasi most US electronic items uses 120 volts power source di ba? OK, thanks for the info.

Tanong about t-amp Stealth mod...
Can I just have the caps changed pero yung modifications na iba pertaining to removing or bridging resistors eh huwag na o dapat gawin buo yung stealth mod?
Salamat

Thanks sir oweida. Your suggestion is well taken. Will check if my AVR has front preouts and i'll try your suggestion. Tube pre-amp BTW will take sometime (and money too) ;D ;D but definitely worth trying.

any new reviews on the t-amp? thanks :)
Just got my tube preamp and modified dual t-amp from jojod a couple of weeks ago.
It is driving my DIY Fostex bipoles with a subwoofer taking care of the bass.
The vocals are to die for and crossing the subwoofer at around 90Hz gives me the bottom kick without affecting the clear midrange and the nice sounding highs.
So basically I have a tri-amped system, two t-amps driving my bipoles and an SS amp driving my subwoofer.
Now I am thinking of getting a better CD player, the Xindak Muse 3.0 or the Cayin 15A is on my wish list.
I use to listen to my Denon AVR and my Acoustic Research for audio (CDs, DVD-Audios and SACD's). Now I only use the Denon for HT, its audio quality is so poor compared to my t-amps.
Now I am thinking, would a good tube amp sound better than the modded t-amp?
-
Now I am thinking, would a good tube amp sound better than the modded t-amp?
The word is not "better". Its "different".
I heard the tube setup of Jetok. Its more "laid back" compared to the T-amps.
-
xxx am just wondering kung bakit wala na reviews lately after its peak a few months back. di ko tuloy alam kung sobrang tuwa nang mga users and theyd rather sit down and listen to it, or too disappointed to even create additional advertisement. thanks. :)
I'm just surmising but it could be because of its clinical presentation - mas madaling pagsawaan. Particularly, for those used to the lush of tubes. Nevertheless, not too many will regret the purchase because of its low cost.
-
pachino,
It could be like this because everything that needed to be said has already been said, everything that needed to be mod/upgraded has also been covered. Matching t-amps with tubes is a lot of fun and your results may vary from one setup to another.
This certainly doesn't mean that the t-amp has passed and as you can see from the previous posts, some like it, some also don't. This is a matter of personnal taste and must be left for the listener to decide.
cheers

I have 3 different types of t-amps, the first one a Sonic Impact, a Amp6 from www.41hz.com, and a Charlize. Like Sir jojo said, all the possible tweaks have been on these little wonders. Each has its own sonic signature, pero generally, they all have basic/common characteristics, analytical, great dynamics and separation, etc. Pero as far as madaling pagsawaan, yung SI oo, madali nga, pero right now I'm still enjoying the amp6 and charlize. It's not as tiring to listen to as the modified SI. Maybe it has something to do with your source also? Right now I'm using either my NON-OS dacs and a modified PS1. Both sound less analytical per se pero nandun parin yung details, ang maganda is hanggang low level detail lumilitaw, which I experienced for the first time with this little amps. Again, kanya kanyang preference yan, pero as far as being too analytical, my belief is that kayang remedyohin sya by using smoother sounding input caps? Well, thats my take on this little amps, mura na considering the sound quality they produce, which is really really amazing. ;D
-
thanks, alexg. congrats on your audio set-up. ive heard a tube pre-amp and t-amp combination and was very surprised with the sound. i think there are not a few who prefer to use a tube pre-amp to add a little "warmth?" to the t-amp. am just wondering kung bakit wala na reviews lately after its peak a few months back. di ko tuloy alam kung sobrang tuwa nang mga users and theyd rather sit down and listen to it, or too disappointed to even create additional advertisement. thanks. :)
godfather don michael son of don vito corleone,
nilagyan mo pa ng "H" eto kamuka mo naman talaga si pareng AL :)
after reading 2 t-amp threads here and @other forums,
still afraid to take the plunge??? ;D ;D ;D

ccc, "panyero" kanya-kanya lang yan. different folks different strokes. if the t-amp aint cup of tea, k fine cool.
t-amp & tubes/vintage are opposites. they are simply different.
t-amp excels in clarity and detail. maybe analytical/clinical in presentation lacking in warmth and emotion but depende din sa synergy ng buong setup ng user. t-amp is just one of the component in the audio chain. while the tubes/vintage are more into lush warm sound, as they say "bilog" "malapad" "mataba" ang tunog, pero sometimes mabagal nakakaantok. sa comment na nakakasawa ang t-amp, i dont think so. kasi... im using two setups- one t-amp based and the other vintage (HK) based. ;D
-
I am using a tube-preamp on my t-amp, add warmth and a bit of "laid-back" presentation, compared to an SS pre-amp. I am still completing my system, next sched would be an NOS DAC and a dedicated CDP.
If funds permit, later I will be getting a tube-amp setup too, some of my music will sound better on tubes... ;D

Yes sir, I have had the pleasure of listening and tweaking a pair of 100W flying mole digital amps. It's a lot mightier and resembles the fast, clean sound of a t-amp but on a different level. Speed and dynamics are awesome but then again can be too clinical at times, imagine guns and roses guitarist Slash playing the guitar without distortion fx. ;D
-
Mga Sirs,

Thanks.
Although I have not heard the Flying Moles, it will most likely sound different than the t-amp. It has more power output.
If the Flying Moles uses the Tripath chip just like the t-amp, 41Hz amps and the Charlize, it would sound very similar to the t-amp.
-
Heard the DAD-M100 Flying Moles paired with the Tono Pre-amp a few months back. Unfortunately, we had it compared with a Fischer tube amp. So it didn't turn out as good as we wanted it to.
However, on its own I think it sounds quite good.
-
oweidah, my sons nickname is chino. dinagdagan ko lang nang pa. hanap lang ako decent tuner then pick an SI. problema nga lang yung phonostage. may kit ba na ganito?
;)
nga pala sowee i forgot chino.
wait for your s4k/cs88 & you'll forget the t-amp.
btw sa t-amp setup, to augment bass, im now using a subwoofer with b&w601s2. tamang timpla lang ayos na!
my t-amps sounded better after 4months. at kanya-kanya paraan yan to improve the t-amp. yung iba tweaks mods, ako naman use tube preamp and ar tds sound enhancer and subwoofer. ;D
-
I agree with Jojo, enuf has been said regarding the T-amps.
For me, I used laid back cables like IXOS 606 pakora (excellent cable I must say!) and another cable I had custom made to achieve the more "laid back" tune that I heard in some tube setups. Then I added a tube CDP and line conditioner. Ok na ok na for me now. Maybe still not as good as a costly pure tube setup, but hey...for what I spent, I am rolling in jubilation for the sound I am hearing.
I listen to very dynamic music (latin, pop, instrumentals) though my SS setup (with brighter cables to bring out the details) and vocals; Jazz (also trumpets) w/ the T-amp. I can say I am in audio bliss w/ these 2 setups. :D
-
for everyone's peace of mind...
I am torturing/brutalizing a recased t-amp project, I hooked it up to a Wharf 9.1 and it's my background music while I tinker with other projects. When I like the music, I sometimes turn it up, close to it's maximum. With my Wharfs, bass is not an issue.
To the t-amp owner: Don't worry - if I burn it, I'll replace it. ;D

I have not found the time to setup my 2 T-amps - but heard them using SMPS of laptop (13Vdc 4.5A) - paired to Coral OEM 10A-100 (97db sensitivity) and a helper tweeter!
alexg setup is how I looked to be the best complementation. The only difference is that I dont have any pre-amp B4 the amp anymore. The roll-off at 100Hz will be taken cared of by subwoofer - so there is no need for the bass tweak as I found T-amp/spkr synergy to be sufficient on the bandwidth they have to handle.
Speaker has a lot to do with T-amp sound. As pachino found it, metal domes will inject its own character on top of the native T-amp sound - so does a good tweeter materials to make the T-amp high shine and fly. So, acceptance of T-amp will always be varied (same with the rest of amps) due to the many variables in our respective setup.
The only tweak i am doing with my T-amps is to have a small heat sink on top of the chip to help on heat dissipation - to minimize heat build-up that may always affect transistor characteristics' variation. Typical boutique speaker may not be ideal for T-amps, which may explain too many fall-off!

...
am just wondering kung bakit wala na reviews lately after its peak a few months back. di ko tuloy alam kung sobrang tuwa nang mga users and theyd rather sit down and listen to it, or too disappointed to even create additional advertisement. thanks. :)
Stereophile's October issue has a review of the Super T. Recommended Class C daw.

Mga boss, how much is the going rate for T Amps now? And where can I buy them that is convenient to go to?

Hi,
From where you are, the most convinient place to go and get your t-amp is Audioworld in Banawe.

Bro would you know how much these cost right now? I think I need to replace my amp because of the power clipping I once told you about.

I would rather have you talk to Joey of Audioworld about the price. They have a thread here somewhere, call them bro, lot's of good people to talk to.

You can also get the t-amps at dai-ichi showroom in megamall. Just got 4 for my office to be used for events 2 weeks ago. They're selling at P2,000 each.

anader mod on my t-amp, 3.3uF Clarity Cap from UK ;D

Review naman sir. Any turn-on thumps? Anyone using different caps?
TIA.

Review naman sir. Any turn-on thumps? Anyone using different caps?
TIA.
mahina na ang turn on thump. pag direct ON mo sya para ng naka soft ON config na bypass resistor. kung i daan mo sa resistor halos negligible na ang thump at konti na ang movement sa speaker cone. thump wise it is a very big improvement over the stock 10uF input cap. sound wise ang ganda rin ng polyprop compared to electrolytic. pero the best talaga kasi free ang cap ;D

Another Class D.

sir bumblebee, after filling out request may natanggap ako email confirm & inform na ipapadala nila. after one (1) month i received the sample requested
-
Good for you, oweidah. Ako, sana me matanggap din. Yung iba yata me return email na ti-nurn down sila. Yung iba naman basta na lang me dumating daw. Sana silence means 'Yes' in this case hehehe
So how's the sound of your T-amp? Any turn on thumps w/ the new caps?

hindi yata claro ang policy ng clarity ah wedr-wedr swerte lang ;D
btw nakatatak sa clarity caps samples ang pangalan ko, personalized. :)
no start-up/power-off thumps on both t-amps tweaked ala stealthmode and sound much better than stock. dati ginagamitan ko ng subwoofer, ngayon wla na.

bai, mas ok tweaked s.i. t-amp used for HF kesa sa stock t-amp. HF no rough edges, sweeter. at maski stand-alone stealth mode (2.2uf) tweaked t-amp ok din. btw ok yung clarity SA caps ginamit ko sa tube preamp-better than the other 2 caps i used before.

SONIC IMPACT super T-amp reviewed at Stereophile October, 2006.
Anyone who can post it here? I wasnt able to read the whole article.
-
sana may actual owner/user reviews din ng super t-amp dito.
how the $160 (8k php) super t-amp fare vs. a stealth mode modified original t-amp - estimate cost= 4k ((t-amp=2k + chassis (350 to 450), capacitors (2.2ufx2= 300), potentiometer=180, binding posts (4x60=240) ,rca(2x30=60) knob(25) led(10),etc+ labor (850) for the tweak if you're not a diyr)).
is it worth the price difference?
btw accdg. to sonic impact website, out of stock na original t-amp.

From what I've read so far, the Super T is better than the modded SI5066.

Audio world banawe still have s.i. t-amp stocks. Good news for QC residents.

What's their SRP?

Hi Juneaki,I dont exctly know but im sure its just a bit lower than in d.i. mega. just ask for a discount. For qc residents, the gas and parking savings alone would be substantial.

Sir, newbie po so be gentle with me :)
I'm really interested to try this Class D amp. Ang tanong ko po ay will an 89dB 8-ohm bookshelf (e.g. Aurum Cantus F5000R) sound louder than an 86dB 6-ohm bookshelf (e.g. Wharfedale 9.1) when paired with this amp?

All else being equal, most likely, but those bookshelves may have different sound characteristics that can only be checked by actual comparison between the two. In my experience, matching the t-amp to a suitable speaker is one of the best upgrade anyone can do. ;)
Btw, I was able to try out a bi-amped t-amp+9.1 combo and a diy'd sub... glorious! :o

All I can say with those TriPath-based amp by 41Hz and the likes is 'WOW'! I owned 2 T-amp used as monoblock, powered by SMPS driving a 10" full range by CORAL.
But with 100-500W available at a very small real estate, those tiny board rocks (for me).
But somehow, I felt, that those DIY boards, being sold at Euro prices plus the hassle of shipping make me think twice, and since I dont have time to tinker with those tiny IC feet (my eyes are not that sharp anymore, unlike my ears) and little patience with purchasing processes, ready made implementation with good facia is more attractive for me!
Is anybody has any information which off-the-shelf products available in the market that make use of Tripath amps?
Ciao

I have come to love the sound of these digital amps.
I hope we can post links, or ways to acquire these higher powered digital amps in this thread.
I have always used low powered T-amps & easy to drive speakers. unfortunatley I just acquired a hard to drive (not biwirable) speakers from a migrating friend. They sound fabulous but I need my Rotel THX amp to power them to sing. When they did sing, I still miss the clean sound of digital amps. So I am on the lookout for any pratically priced 200w digital amp.

@aHobbit,
i have ordered a fluke87 dmm from a guy from Indianna, boards and parts from a guy in Pennsylvania, and more recently boards from Poland, all thru the mail and during the christmas season, all came thru without any hassles...i got what i paid for... our postal system today is much improved i should say....and western union rocks...
regarding those small parts to be soldered on boards, you can buy those tools used by celphone repair techs...
what i am saying is if you want to diy them, you can... ;D

Marami ng meron nung amp3 (25wpc) ...but with the ready-made sonic-t amp (15wpc) wqhen you upgrade , it's better to try the 300wpc model.
iSa pagtinker naman ng IC,I think JojoD is the most qualified person to answer this. I think what he does is to subcontract the soldering of the IC to a celphone technician .
The amp2 in 41hz website (300wpc model) , i think has issues and jojod is again d'MAN to answer this.
$89 yun kit exclusive of shipping cost pero sa mga nababasa ko mali-mali yata yun mga pinadadala na value nung parts ng kit although sagot naman nila but yun hassle sa tagal.

Hello mga masters... just want to enhance also my electronics knowledge to these t-amps.. but i am zero knowledge with these projects of yours... nakakainggit kau eh.. gusto ko rin magproject ng t-amps but my question is, is it available ba in project kit form/package (pcb/electronic parts etc)??.. or kau nag-design ng pcb layouts/circuits??.. kung meron sa raon na project kit na, to be assemble na lang at home and magkano kaya ang expenses or damage ng pocket ko??... just asking lang po and thanks in advance..... hapi balentimes!!!.

google sonic impact t-amp for an idea of how it looks like. you can buy SI t-amps at audioworld (in Banawe), then modify it to your heart's content.
-
Tanong lang po mga Gurus,The guy at daichi megamall told me when I got a t-amp from them that using hi level inputs in an active sub connected to the speaker out would strain the amp and is not adviced.
Today I got a new set of Aurum Cantus f5000r from Spectra(got the first for our Ht at Audio Amplified.).Anyway they told me doing a series from the speaker out to an active sub would not hurt the amp.and they proved it by connecting their klipsch sub .Of course it worked and sounded wonderful.In fact it sounded much nicer to me at least compared to the tube amp f5000r /klipsch combo they had running.
Anyway is there any long time effects in running an active sub,I dont want to spend more on a separate pre amp and I dont like using a spliter from the sound card i use just so I can use the sub.
Thanks in advance.

many thanks sir Jojo... how much wud it cost??.. this is on a project kit when i purchase, tama ba?... is this also available in raon??.. pasensyan na medyo makaluma yung alam ko with regards on this kaya me medyo nagtatanong... 1st timer kasi me mag-project just like this... integrated amps ksi are available in local stores such as alexan, decco, etc so i just wish to learn on this also... thanks ulit in advance...

The t-amp has a BTL output, meaning the output grounds are not tied together. Please make sure that your sub does not have a common ground, other you will be shorting your t-amp's output ground together.
If your sub has separate input grounds for it's high level inputs then there is nothing to worry about.
-

It's more appropriate if you can ask them (Audioworld) about the price. It is actually a battery powered. I haven't seen any shop in raon selling this as of now.
Here is a link with a pic of the actual unit...
http://www.tnt-audio.com/ampli/t-amp_e.html
Search on Google for more information.

@JojoD818
Thanks for the quick response.I will try to google if the wharfedale sw-150 has separate input grounds or is there a way to see this in the binding posts?ty again.
-
I'm not sure if it has any markings near the binding posts. An easy way of confirming it is by using a multitester and check for continuity between the two grounds on the high level input. If it has a high resistance then it's most likely to be a differential input, but if it is a dead short then they sure are common.

Just read about the amp2, 2x300w!
Wow, tempting. But mahal daw power supply sabi ni Jojo. :'(
-

Wow, tempting. But mahal daw power supply sabi ni Jojo. :'(
let us see, you will need a 1000va torroid, @7000, 2 x 35amp bridge rectifiers @100, two 22,000uf/100volt caps @970 so for power supply, be ready to spend around P9000 pesos....basic material cost pa lang yan..
the amp itself costs around 4000 plus shipping and assembly cost should set you back another 10% of total material costs.
you can cut the cost of transformer in half perhaps by using EI's instead, probably will cost you 2500....
-
Sir Tony, How about this?
The standard solution with these boards is a 2x300W amplifier. However, there is space onboard for alternate solutions allowing higher power outputs / lower impedance loads, up to 2x600W into 4 ohms with +/-65Vpower supplies. This requires some components to be added or changed.
Magkano aabutin yung expenses (estimate) ? Interesting kasi... :D
1500va daw kelangan. How big are these transformers?
Anyone know of any positive reviews of these higher powered digital amps?
TIA :)
-
1500va daw kelangan. How big are these transformers?
IMHO 1500 is already overkill, these amps are about 90% efficient so at 2 x 300 watts, the minimum traffo size is 700va, 1000va seem just right, but of course if you were to order them locally, it would be better to be on the safe side, 1500va is not unreasonably high..
in my book a 1000va transformer will have a core area of 2" x 3" of scrapless iron and weight is around 28lbs.
btw, if you are going to use these amps in your home, you may even get away with a 500va transformer, you wouldn't need to run the amp full power, what the rating simply means is that, you will have plenty of headroom on transient peaks...most of the listening in the home is done in the 1 to 5 watt levels anyway, unless you live in house isolated from neighbors... ;D

OMG, 28 lbs! I thought it was gona be similar to those compact size lightweight T-amp casings.
Does the 500va, 1-5w level also apply if you have "hard to drive" speakers?
-

yes.....500va is a plenty... ;D even for home use this is already big...

Matt,
Tony's computation is just about right on the money and as I said earlier (when we talked), a 1000VA tranny already has an "allowance".
Tony,
The peso is gaining against the dollar, price of gasoline is going down but tranny materials aren't :(.
:)
-
Just read about the amp2, 2x300w!
Highly interesting.
Has anyone here tried this already? Feedback naman dyan ... :)

yes, last time i was here, core cost P72 per kilo and copper wires were at 400 per..i have not been to armstrong as of yet to check out prices...there is a shop in kalentong selling copper wires at lower cost than armstrong fyi... ;D
so my estimate is for an EI traffo rated 500va, material costs will be in the vicinity of 800 pesos..

Hi Sir, on the actual price of the commodity you bought, how many percent usually is the overhead expense (shipping, handling, taxes, etc) - how long does it take to get a firm order?
Of course I want to DIY, but got no time for it for now! :( :(

Am interested for the high power amp only for the subw where issues on amplification is not at all that detectable. For the power supply, the cheapest route is the SMPS - and a little research how this is done and where it could be sourced (assembled surplus) can yield multiple savings and DIY time. I have no use of high power amp for audiophile listening.
For audio stereo listening, I am just interested on something like about 60wpc, and a commercial product sporting this could provide the base which I can tweak - no more tinkering on the casing/PSU base and pre-amp! I dont need the bass portion (100hz down) from it - eepal lang yon sa mid/hi FR ko. The example of this is my T-amp which just uses laptop-based power adaptor (2 pcs NEC with 13Vdc 4Amp output :o :o). Very easy and very cheap! 8) 8)!
Kung pang rakrakan naman sa labas, the 300watter and a cheap PA speaker (like the Konzerts beauty) will suffice!!! ;D ;D ;D

please call me Tony, ;D ....the ones i ordered thru the mails, shipping ang handling depended on weight of items. for example, the boards i ordered with some parts costs around U$250 and $9 to ship to my house, i did not pay any taxes or anything. The ones i ordered from Conrad Engineering was shipped via FedEx/Air21 and the forwarder billed me P3900 which according to them was for taxes. when i complained to Conrad Engineering, julian wales gave me a U$45 rebate, no questions asked. i made payments thru western union...I have not lost any orders so far.. ;D
delivery takes about a month...
if you want to use smps, you can, there are surplus modules out there rated at 12 or 24 volts and high current. if i remember it right, odyopayl posted a source in bicutan selling such items...
-
OT. aHobbit, where did you get the adapter? Yung mga nakikita ko kc 19V e. Thanks.
-
So if a 500 va power supply will do, does it mean that you could get a 1500va tranny and 3 amp2's to make a 6 channel power amp for HT purposes? :o

yes....even a 1kva one will do.....but of course if you are going to have the traffo made here, then it is a different story altogether, traffos made here are always undersized....
btw, i emailed them asking if they accept payments thru western union... ;D

if you can get to the store in bicutan, chances are the sellers will not know what those modules are and they would not know their real value. they could just as well end up canibalized for their copper and other parts...sayang.... i haven't really looked at soler and evangelista in the RAON area, they could be found there also...just be patient when looking...

even the pc atx psu can be hacked to get 24volts at 10 amps for 240 watts power... all that needs to be done is to beef up the -12rail by replacing recifiers from a 1 amp to say a 20amp type, so the 12 volt rail and the -12volt rail taken together can add up to 24 volts...

Tanong lang po mga Gurus,The guy at daichi megamall told me when I got a t-amp from them that using hi level inputs in an active sub connected to the speaker out would strain the amp and is not adviced.
Today I got a new set of Aurum Cantus f5000r from Spectra(got the first for our Ht at Audio Amplified.).Anyway they told me doing a series from the speaker out to an active sub would not hurt the amp.and they proved it by connecting their klipsch sub .Of course it worked and sounded wonderful.In fact it sounded much nicer to me at least compared to the tube amp f5000r /klipsch combo they had running.
Anyway is there any long time effects in running an active sub,I dont want to spend more on a separate pre amp and I dont like using a spliter from the sound card i use just so I can use the sub.
Thanks in advance.
Gubs
Sir, can you give us your impression of the T-amp + Aurum Cantus F5000r combo? Am also considering getting that pair. :)

... you understood my idea in the PSU area ... there are PC PSU designed for 500W ... am toying at that idea ... how about the battery chargers of old PC UPS ... they abound somewhere?

my experience with old pc ups' is that the batterry charger and inverter transformer is one and the same and that they are auto-transformer wound, therefore, is not safe to use here since there is practically no isolation from the 220volt mains...
pc at or atx psu's can be had on the cheap, you can even series connect them if you are lazy to do any tinkering of their insides... ;D

@romymartinez
The f5000r must be one of the great bargain speakers sold here in the Phils. where they are sold cheap as compared to other countries.
A and b tested them with another popular brand in the same store selling for the same price and the sound was much more detailed and smoother,as the guy in the store said these put out almost perfect midrange to upper frequencies compared to others of the same price ,thats why he was running them with their tube and sub combo at the time.A an b tested with the t amp attached and I was stunned by the clarity and much wider soundstage
The only drawback was the relative lack of bass as I was testing the Eagles Live Hotel California track. Thats when he attached the t-amp to their klipsch sub and some balance was brought back.
Used in our office with soundcard and foobar kernel streaming as source,sounds still clean and clear though it definitley lacks in the bass department some bass tweaking with foobar equalizer helps bring bass back but go to far and it distorts.Also the f5000r seems to need more volume than the w brand speakers I tested and the Tannoy 609 dual cocentric speakers we still have.Though the other 2 dont sound as good.
The lack of bass seems to be from the known stock t-amp bass fall off,and some bookshelves at least like the 5000r dont have the bass extension to begin with.So now will hook up my sw-150 and maybe later mod the amp (input cap change)to help things out.Our other f5000r attached to a Marantz sr4500 with sub sounds just right to my ears.
Hope this helps.

thanks sir tony!
just last year, in the other forum, a clearance sale of Motorola-manufactured gear went on sale. It sports DVD player, decoders, tuners and ... 5-channel tripath based T amplifiers ... so disappointed am not so ready to make purchase as I am not too familiar with foreign transactions ...
anyway, I still hope some people can provide info re commerical gears sporting this type of amps because most of the time, somewhere, these gears are being sold for the cheap!!! - remember the original T-amp?
-
I read in one of my HT mags that Motorola used tripath amps in their receiver. Duno if it became popular though.
-
Also, the f5000r seems to need more volume than the w brand speakers I tested and the Tannoy 609 dual cocentric speakers we still have.Though the other 2 dont sound as good.
Sir Gubs,
The F500r is rated at 89db 8ohm while the "w" is at 86dB 6ohm. I'm now wondering why the F5000r "seems to need more volume". :)
-
@romymartinez
The guy at the store said the real rating of the f5000r is closer to 4 ohms than the stated 8 ohms.But at the back it says 8 ohms I tend to believe him cause both the other speakers I tested had 6 ohm ratings but were louder at the same volume setting.I dint ask him where he got his info but is probably correct.The f series Aurum he said are a bit harder to drive but sound very good.Anyway the t-amp sounds good with just one driving the pair at up to moderately high listening levels.You can ask him there directly Im sure you know his name.hope this helps
-
I read in one of my HT mags that Motorola used tripath amps in their receiver. Duno if it became popular though.
It is not popular of course ... for the simple reason that Motorola is not known to manufacture audio consumer goods ... thats why when they went for clearance sale (so low), a lot of audio DIYers buy those units in volume (3-5 units)!!! :o :o
This are those rare chances when perceived-valuable units by DIYers audiophile, can be had so cheap just because it is unpopular to the majority who will not give a d ;D ;D n whats inside it. this is the least thing any interested hobbyist would desire, or the price will just soar!
-
Thats why MARKETING plays a very important role in this business, as what I read in another thread:
"beware of companies who spend millions of dollars in marketing their speakers, but give you..."
And there were immediate reactions on a speaker brand. ;D
I would not doubt Motorola's performance in the HT arena since there are some gears in the HT industry that use Motorola processors. But the general population doesnt know that....
They lack marketing...
-
for the simple reason that Motorola is not known to manufacture audio consumer goods ...
Motorola makes lots of money on computer and datacom products...such that they sold their discrete semicon plants and that came to be known as ON Semiconductors.....
There was a time whem famous brands like Marantz, Fisher and others went overseas to Tamura Radio Corp in japan to make amps for them....
-

....
right ... for motorola, the attempt is just to test waters ... no difference now, as major computer makers such as HP or DELL, are now into big consumer displays (LCD TV), and HP attempted doing HT, PC style ... I just think, it is just a matter of time that they will get the right mix/combination, and that the digital convergence of what is presently known separately as computing and audio, is just a matter of short time!
Of course, for us into this never-ending hobby (never really understood it whether we are running after the sonics, or are really enjoying hearing different gears at different point of time :D :D :D) the sale of those trash of others, is indeed a gold mine for us! ;D ;D ;D

interesting work of art ... near tube amp for low sensitivity speakers ... not a bad price for a tube pre stage ... somebody out there tried this?
-
going back to tripath amps, i am of the opinion the psu should not be an issue with these amps, even unregulated conventional psu's will do.
so even if matzer is eying on 2 x 300 watts, nothing can prevent him from using sa a 300va transformer for psu. the transformer will limit the power for sure, but then for a home environment, this is realy already huge...
-
Hehe, you can actually sense my excitement for that amp over the internet. ;D
Sir, I actually plan to have the 2x600w variant (if possible), I am actually already thinking of ordering the casing & tranny (1.5kva) abroad soon... Just waiting for more positive reviews on that amp. :)
I know its overkill, but I just cant resist.... I like overkill. :D
Besides, my friend told me he heard his hard to drive speakers (now mine) being driven by 400w @ 4 ohm MF monoblocks & it was fantastic, even at low volumes. I want to experience the same thing w/o shelling out huge amounts of cash for MF monoblocks ;D.
Also, is it possible to use 2 units 750va tranny so it switchable if you desire low power rating?
-

yes... ;D

Cant wait for the day when slim, lightweight digital receivers are mainstream. 7x200w? Wowie
The HK DPR2005 was one example, but it probably did not become popular as I saw it on sale at very low prices. I wanted to make it my sleek surround pre/pro for a time, but changed my mind.

malabo yan iniisip mo na magamit sa amp2 sir, isang V+~GND~V- lang ang possible connection sa board for both channels so pano kaya gagawin yun switcheable?
I must be hybernating this past few days and missed this new concept of utilizing 2 trannies in a switcheable manner. ;D

no tranny in the conventional sense, smps most likely, just like what aHobbit was harping on, several posts earlier....

paralleling of transformer secondaries need not be done on the boards, there are several ways to do it...and it is not a new concept, just a simple implementation of electric wirings.... ;D
this class T amps is a brand new ballgame, class A/B techniques with respect to power supply need not nescessarily apply....
-
I'd rather use a single tranny which is up to spec and keep things simple. there is not much sense for me in complicating something that is already rather complicated.
I'm sure that Matz's reason for this is to keep costs down but at the same time keep the performance up. ;D
-
complicated?
even Leach used two trannies in parallel when he made his 250watt super amp, and that was around 1975. ;D
matzers idea of using one 750va first then having a 2nd 750va as an option makes sense....you may be in for a surprise yet, once you realise that the 2nd 750va my not be desireable after all, hence not needed anymore...i think it is worth trying.
a 750va transformer in my book will have a core area of 1.75 x 3 inches, the built up transformer wieghs around 10kgs....anything less than this is underrated.
-
this class T amps is a brand new ballgame, class A/B techniques with respect to power supply need not nescessarily apply....
Walter Jung wrote an article in the Audio magazine entitled, "Build an Energy Storage Bank" extolling virtues of very high capacitance in amp psu's, when i saw him post in "wiredstate" i emailed him asking him about his article, and to my surprise, he says that he doesn't find his article of importance in todays' setting. what this means is that thinking changes.
So now i say that what we know about classA/B amps with respect to power supply can be set aside as this switching amps are a different animal altogether.
besides, what good is a transformer that can deliver 1000va when all the while you will be listening to music whose energy content will never require 100va of energy?
-
That is of course viable and I have tried that before too. But the decision would be up to the owner of the amp2 that I am building and my recommendation remains the same.
Complicated by Avril Lavigne pwede yan. ;D

You read my mind sir! The idea is basically for 2 slimmer transformers (for slimmer casing, sleek look) instead of 1 bulky one, then using only 1 750va for the meantime w/ an option to upgrade to another 750va in the future in case more power is needed.
And correct, if the 2nd 750va is not needed, then no need to spend more. I believe 300w is enough (600w is just ...tempting, mwahaha).
Now hopefully amp2 gets more good reviews. :)
-
You read my mind sir!
hehehe...i am a lot smarter than some people care to admit... ;D
if slim is your choice then, you have to get torroids..... ;D the core size i mentioned is for EI trf....

jojo,
they need not know, after all i am here to sell ideas only, i am not here to make a living out of this hobby. i have my own good paying job.....therefore i have no vested interest to protect..... ;D ;D ;D remember it was me who asked you to join this forum when i met you at diyaudio? ;)
going back to topic, these tripath amps are a lot easier than clas A/B amps since you don't have to watch out for the biasing network, which when done wrong could lead to a fried amp...as long as you mount components correctly the amp will work the first time.
-
sirs,
regarding transformers/power supplies, if i remember correctly nad304 (& 306) used 2 trannys.
the nad brochure stated: extended dynamic power (EDP) - "the key to this extraordinary performance is the use of dual power supplies and a signal sensing controller. The low voltage (thus low cost) supply operates up to the amp's "rated"(35w) continuous output level, while the high voltage supply provides bursts of high power whenever the music demands them (up to 120w). although the latter supply provides very high output current, it works only on brief bursts, so it does not overheat the amp. When driving very low impedance loads (down to 2ohms the low voltage power supply provides most of the power to drive the loudspeaker so the high voltage higher power supply still has ample capacity to deliver the musical climaxes."
pwede din kaya ang ganitong design sa t-amps?
tnx
-
i remember that, i think i still have that PM you sent me as a memorabilia. ;D ;D ;D
the chips from tripath controls the biasing (or switching?) of the outboard transistors, a very easy project compared to a leach. the only challenge for myself was to solder those smd parts. and they don't even need a heatsink when running at low to moderate volumes.
as long as you mount components correctly the amp will work the first time.
correctly and properly is the better word, due to the size of these amps, a hairline short can be catastrophic.

oweidah,
class G, or sometimes class H ang tawag dyan, it can also be implemented using a single transformer with multiple secondary windings. the amps itself is a classA/B type that operates at low voltage when input signal is low, implications nito, low power consumption and less heat. now when input signal increases to a point wherein the amp is about to clip, then the higher power supply kicks in, thus clipping is avoided and larger music power is delivered to the speakers.
Class D or Class T operates in a different manner altogether, the output transistors or mosfets do not operate in the linear region just like the class A, A/B, G or H does. they are either off(cut-off) or saturated. therefore very little power is dissipated in the output devices. PWM is the manner by which these amps operate. In a nutshell, the input signal is sampled for pitch(frequency) and amplitude(level) now this is replicated at the output by chopping the dc rail voltages at high rate, say 40khz, (this is way above human hearing of about 16khz!) then this chopped waves are modulated in accordance with the input voltage and output voltage is then delivered to the speakers that are almmost identical to the input voltage. are you still with me? ;D the coils in the output side then acts as a low pass filters so that frequencies and harmonics generated by the chopping action do not reach the speakers...
Oh, I can almost see analog guys and audio purists squirming and raising up their arms in disgust, but then who can argue with success? these amps realy sound very good, according to reviews...and those that have tried them...
Now, going back to your original question about the possibility of using that psu on T-amps? i say no, not required.
you can use any psu and that the nice thing is that the psu need not be regulated, the only reason to use smps supplies as what aHobbit was mulling is wieght and bulk consideration and that they can be had for cheap. t-amps are not plagued with psu issues as with class A/B amps, whereby operating points are affected by psu regulation.
Finally, there is a limit to the level of psu voltage that can be used, and this is because the ouput switching devices have breakdown voltages that must never be exceeded in order to ensure safe operation. Lower ppower supply voltages means that lower output will be delivered to the speakers and vice-versa.
Whew, my fingers are tired! ;D
Oh, and another thing, kayang-kayang i-assemble ng mga celhone repair technicians itong t-amps, because they have the equipment and the training to work on surface mount devices....

tnx for the explanation. i was kinda hoping na pag pwede yung ginawa sa nad 304 (parang kambio pataas only when needed), baka pwede din gawin sa mga t-amps hehehe ;D
for now just wait n see for new developments. i think just about everybody is hoping for digital amps with more power at a reasonably low cost :)

... wazz up wazz up ...
I personally think that pwer supply is not a big issue in tripath amps. So, an SMPS style, cost-wise maybe cheaper to make if one knows how? For me, the easiest is to find those surplus items that can do the job.
The HK model that sports digital amp is too expensive when offered to the consumer. Like BOSE, I think HK tried to make the slim-is-best (translated: costly) - so not really acceptable to consumers (and to audiophiles ... like me in the cheap ... would like it ;D)
Many branded names are now testing the waters ... though am a bit surprised at the slow pace that the typical names push the T-class ... while many DIY sellers have a lot of kits et.al ... probably (as usual) commercial issues - will create a competition so fierce, high power amp can be had for much much less - and may erode most of the margin in consumer audio. Really surprised panasonic is not around in this corner of the world to have a listen to them!
The hybrid amp in NAD, originated from the old Marantz (long ago) - to me, it just made amps more complicated to design.
My idea of new hi-tech audiophile room is to have a very clean, even loud sound with no amp gears visible (virtually invisible) to the eyes :o :o - only small elegantly-designed CD mounted on a wall, enhanced by lighting , and a small remote control. Those t-amp can easily make this possible, in partnership with current crop of low-sensitivity but decent speakers!

I have not ventured yet to know the intricacies used in Tripath amp ... but got the impressions from my different readings that Class T (T-class amp) is different from class D (Digital amp) :-\ :-\ :-\ ... or probably am not really reading properly! ;D ;D ;D
Also reserving my impression why T-amp is so good and as some hyped it ... sounds near-like tube ... current source???

Tripath's customers include Denon, Hitachi, Motorola, Onkyo, Sanyo, Sampo, Sharp, Sony, and Toshiba... wins for flat-panel TVs from Samsung, TCL, and Eizo.
The key to Tripath's continued success is the advanced sound quality of the Class-T® design in comparison to Class D amplifiers.
Pastorfield summed up his appreciation of the Class-T®'s performance in the Panasonic MXE CQ-C9800U like this:
"After a couple of hours of listening, I became a Performance Digital believer. The stereo spread was noticeably more pronounced, and I kept hearing little details popping out (reverb on a snare drum, vocalist's lips smacking, amplifier buzz) that I wasn't accustomed to hearing, making the recordings seem more lifelike. And it wasn't that the mix was being reproduced inaccurately by the Tripath amplifier. On the contrary, I was hearing all the information on the CD reproduced pretty damn close to perfection, just like you'd hear on a high-dollar home stereo system."

baka mahirap matanggap ng ibang audiophiles na ang hamak na tripath chipbased amp ang magbabago ng hilacha ng mundo ng audio pag fully developed, reasonably priced and marketed not as diy kits but presented just like other ss amps that one can stack with other components ? ;D
malamang, once the true nature of class T amps are revealed, like the following quote:
Class-T® is the name for our proprietary architecture that improves on general switching amps. We use a combination of "predictive" and "adaptive" processing. On top of that, we use a very high switching frequency. The basic idea is that we look at the incoming signal to determine the best way to encode it, making sure to minimize interference or mistakes. We then use feedback, or "adaptive" processing to analyze the output and keep the system stable. The high switching frequency allows us to correct any issues quickly before they become audible. Because of the robustness of the system, we can maintain our fidelity even with mismatches in the output FETs [Field Effect Transistors], power supply "ripple", and other issues that normally require significant engineering time and manufacturing cost to prevent. The Class-T® technology allows us to reach very high fidelity levels and keep THD+N [Total Harmonic Distortion plus Noise] figures better than many A/B amplifiers, while still delivering the efficiency of a switching amplifier.
the difference between classD and classT is not very obvious to me, i think they are one and the same, with class T a refinement of classD, but still classT operates on classD principle.. ;)
here is an FAQ wiki done by the guys at diyaudio, it is best that you read them carefully in order to be enlightened more:

SIr Tony,
cant find anything explaining difference :-\ ... in the crutchfield advisory, there is an interview with Tripathi the detailed principle behind D & T differences, but cant enter due requires login authentication ...
... agree T operates like class D, but unlike class D, they have other things inside that set it apart from class D ... still looking for some clear indicator though :-* ... and yup, it looks class T is class D with higher clock rate adaptive/predictive circuitry ... kinda very good implementation making mismatch in output transistor, PSU ripples (et.al) of no effect to the final output!!! :o :o :o
-
My understanding is that Class T is to Class D as chipamp is to SS.

and most have only one chip so if it's busted then it must be it. ;D ;D ;D
a client of mine even asked me to parallel an auricap, a multicap, and a mundorf for the input caps. geez... ;D
kinda OT: do you still remember the psu topology that Bob Carver used for his Sunfire amps? the name escapes my mind... it's called "linear tracking" something... thanks
-
Carver used a "comutating circuit" at the power transformer primary side with a triac, SCR's can also be used here. The conduction angle of the triac is controlled by the input signal, so now when the music demand is high, the conduction angle increases thus higher rail voltages are available. This is the reason why his amps are rather light for the power output. Efficiency is also high in this case.
sobra nga yang client mo...all he had to do is get a Teflon cap, teflon is the best cap around, kaya lang he will haveto spend around U$200 for a single cap.... ;D

something like that, the efficiency is very good and so less heat. I forgot na what he called it eh, linear tracking power supply or something like that. ;D what I remember was sgs thompson released some chipamps with dmos technology that uses different supplies to increase efficiency and literally reduce heat to manageable levels. the release of this tripath chips has been an exciting path for us diy'ers, though the topology remains the same, the implementation is endless.

To the class -D gurus (JojoD818 in Particular) I just got a brand new Super t-Amp from one of the members.To make a long story short it was working fine out of the box last night until this morning when i decided to a/b test it versus my Marantz avr.I switched the speakers with the Marantz using banana plugs ,upon returning them to the Super t-amp there was no more sound although the blue light was still on.I have tested differernt sources, pre outs,including straight sound card and different 12volt power supplies all resulting in no sound.
Is there a way to repair this unit since the sellers guarantee was for it to work out of the box nothing more. Maybe something was shorted when i was switching speakers.
Thanks in advance.

Just got a Trends Audio TA-10.1. from Singapore had it sent to sister in laws place there from audiotrio , www.audiotrio.com for S190.00 plus S10.00 delivery they delivered in one day.
Anyway connected it to my Marantz sr4500 preouts connected it to identical fronts (Aurum Cantus f5000r)and put the other speaker set to speaker b binding posts.
Anyway the preouts have very weak output even with plus six in the speaker level setting so I amplified the output with a cheap Behringer HA400 micro Headphone amp with 4 outputs.Also the ta.10.1 seems to have low gain either that or the speakers needs more volume (harder to drive)or the preouts as mentioned are low volume ,Im not sure anymore.
The headphone amp gave a much stronger signal so I dont have to turn the reciever s volume to almost 0 just to get my desired listening level. Also one of the Behringers output feeds the sub (with splitter box for lfe from avr)since I use Pure Direct mode which kills the sub out.
Anyway it sounds good out of the box but not yet as detailed as I remember my stock sonic impact which was fully broken in.
Hope to have better luck with this one since the Super T-amp I bought from a fellow member died in one day and is no longer repairable.

@Gubs,
Kindly keep us posted of your impressions on the Trends TA 10.1. In DIYAudio they said that it takes 100 hours of burn-in.
-
Been running about 20 hours now,Still a bit muffled I thought no improvement I thought I wasted money on this thing,until a fellow member told me to take out the headphone amp and just use straight pre outs , I just increased the left and right levels to 8 + to 10 +
The difference was huge,even in stereo crossed over to 80 hz or full range large speaker setting ,compared to pure direct.
I couldnt understant why my old t-amp sounded better straight from the sound card. Pretty stupid of me using a cheap headphone amp to amplify the signal.Anyway hope things improve further after a 100 or so hours.

You need 12V. According to the TA2024 datasheet, max is 13.2V.
If you're using 8-Ohm speakers, the lower current (1.5A) PSU may be enough.
-
There are a couple of 12V SMPS in RS and Farnell. Mahal nga lang. Anyway, some are using 13.8V w/ good results.
-
RS as in RSPhilippines. Shipping is just Php100 kung magaan lang at nasa Manila ka.

If you're using 8-Ohm speakers, the lower current (1.5A) PSU may be enough.
You're right, 13.2V is the max operating voltage. The datasheet says its absolute maximum supply voltage is 16V and I was stupid enough to try and use it with a 15V supply and puff it went. ;D
Oh well, it was indeed an experiment on how to destroy your t-amp. ;D ;D ;D
-
I can't accurately comment on that since I don't have the numbers on the output of those psu. I did have an experience many moons ago during those 2-way radio days when one of them 13.8 reg psu cooked my portable coz it had more than 14v in the output instead of 13.8... why not measure them before you buy, that way your t-amp is safe. ;)
-
one other option for 13.8V supplies is to put a 1.5-3A rated diode in series. this would drop 0.7 volts on the diode and you will have ~13.1V going into the t-amp.

or 2 diodes in series rated at 6 amps....fyi 13.8volts is the nominal voltage of a fully charged 12volts car battery, RAON grade psu's specially those unregulated ones will have high open circuit or unloaded terminal voltage, sometimes exceeding 18 volts, specially when you wall outlets give greater than 230volts ac..
-
share ko lang my answer to a prior question:
sir gearhead, thanks for your suggestion re: placing a diode in series in a tamp psu. is this easy to do? not good at diy. thanks.
well, this is a very easy thing to do. the hardest part though is how to conceal it. pwede mo kasi ikabit in series with the dc power plug, kaya lang syempre nakalabas siya. you can put shrinkable tubing (from deeco) over it para di masyado halata. pero the best siyempre is kung maintegrate mo siya sa box mismo. you can choose to put it in the psu box or the amp box, whichever is more convenient.
one advantage if you put it in the amp after the dc socket is that magiging reverse polarity protection na rin siya. kasi once you insert a wrong polarity plug walang current na tatakbo sa amp mo. i read kasi sensitive pa naman ang t-amp sa proper polarity.
**************
anyway, ako naman po magtatanong. since yung t-amp is 12V, and usually yung mga pc cdrom's are 12V too with analog outs (headphone and yung 4-pin line level out sa likod).... me naka-try na ba nung ganitong combo? how does it sound?
-
been using zebra labeled "dc regulated power supply" model ZR600-HDC 12V/6A for almost 1 1/2years powering two (2) t-amps at the same time.
measured voltage during actual operation is 13.2volts.
so far so gooooood ;D
-
Or maybe...why not modify your tamp and install a SLA battery just like mine and you can have your caps mundorfed depending on your preference. JojoD can do it for you. I am very happy with mine and is now driving a wharfdale 9.5 floorstander with ease. Although I have 2 tamps in my unit, JojoD can also do it for 1 amp.
The advantage here is you dont have an external PSU unit and the power being delivered to the amps are stable. It still maintains its portability as you can use the battery alone without the need for AC power. Contact JojoD for details.

An all in one solution. Sounds nice. I would like to have separate psu boards for that. Buti na lang single supply lang ang TA2024.

Saw a power supply at Handyman yesterday, brand is Premier (589 pesos). Ideal for T-Amp ang DC output rating at 12V, 3 ampere. However, the case only indicated that its "bridged" and didnt say that its regulated. Kindda different from most converters (if it is one) as it only has no voltage selector. So im wondering if this is a regulated PSU or a converter with a simplistic output. Bagay pa naman sana sa T-Amp ang output. Thanks.
can a 12V 5A supply be OK for the T-Amp? I saw one kasi from a Surplus Shop selling computer parts and I think this was used as a laptop power source.
Thanks.

Hi oweidah,
Nice to see people still happy with the t-amp set-up. Congrats and it seems that you have found nirvana in your t-amp set-up.
Mine too have been modded by our good friend JojoD. I have 2 t-amps in bi-amp mode (also can run in single amp); I think the caps are also 2.2uf (Master JojoD, please correct if wrong) but have used Mundorf white caps (very happy with SQ, big tight bass and easily can drive floorstanders); power supply used is SLA battery to ensure clean constant power with charging function (can also run on batteries alone); have paired these babies with a tube pre-amp also diyed by JojoD and its a mate in heaven. The pre-amp is a constant current source w/ fully regulated PSU board. The hybrid combination is perfect and can equal 3-5x equipment set-up.
Now waiting for one more important link in the audio chain -- diy tube CD player. I have already tried with a commercial tube CD gear and is also a mate in heaven. After this, upgrading can stop and enjoy the music.....

JojoD is making it for me.
Just want to correct that it will have a tube section and not just a tube buffer.

Sorry, what is the difference between a tube section and a tube buffer?
-
Maybe he meant bypassing the cdrom's "analog" section. DAC's output going directly to the tube buffer or section.

Saw a Newstar regulated PSU. The one which you plug including the PSU itself. Adjustable voltage/ampere? Parang converter. Pwede sa T-Amp?? Thanks.
Got one yesterday model NA-6000 from DIY Ever and I tested the output with digital meter and the outputs are over by more than 4 volts for any of the 9,12 & 13.8 volts selection! I ended up with the selector in th 9v position where the actual output is at 13.1-13.3.
I'm planning to return it since am not sure if it's a defective unit or that all units of this model have these characteristic.
-
I have a denon pma-680r amp. Can I use it as a pre-amp to the SI? How do I connect the denon to the SI. The denon seems to have no pre-out but it has a selector switch on the front panel that says "Record Out Selector" with choices from all inputs (CD, Aux, DAT, Phono, etc). At the back panel there is a pair of RCAs labeled "Record Out".
TIA.

is it a regulated model? if not then that's just fine because it has "no load". the psu is ok but please don't use anything over 13.2V...

No, it is not reguated. I have returned the unit and bought a zebra regulated 13.8 v and when tested stayed at exactly the stated voltage. Am using it now on my SI and it seems ok....so far ;D

Yup...have used the zebra for so long now and had no problems. Actually when tested the voltage is normally less that 13.8.

geja, 13.8v 1.5 ampere yan? meron kasi zebra porta 10 13.8v,1.5 amp, ok na kaya 1.5 ampere sa tamp? salamat
From my experience 3 to 6amps is better

Good thing you replaced it with a regulated one. Although 13.2V is the operating voltage of the t-amp, I guess you'd be better off with that 13.8V rather than the unregulated supply.
Cheers

I had the chance to pass by Sights and Sounds Shangrila last Monday and heard on demo a Trends Audio TA-10.1 paired with a B&W 685. To my newbie ears, they sounded very good!
-
Hi Romy glad to hear na you like what you heard on the trends. ta 10.1 Im using my trends with monitor audio rs6 floorstander, and for me it also sounds good. If napadaan ka ulit sa sights and sounds try to audition naman the kingrex t20u tamp, it comes with usb dac for computer use it bypasses the sound card for better sound quality.

Can you give a short review of the kingrex t20u t-amp? How much is it at s&s? Read in reviews it sound like a tube amp, can you confirm this. Tnx :)
-
May bago nang Sonic Impact t-amp. Costs USD50, and I estimate it will cost 3k to 3.5k landed cost (using my suking forwarder) from the States. Mukhang may improvements, like a built-in headphone jack and an included 3A AC adapter.
Looks like this:
(http://www.partsexpress.com/images/300-958m.jpg)
Will order one for my office setup shortly. What Sight and Sounds has is the old t-amp. I'd like the gen 2 since it looks good and may kasama nang 3A switching power supply. And it can still run on batteries. Pairing it with the Diamond 9 surround speaker in a nearfield setup. Tested that with a Trends amp at S&S and it actually sounded better vs the Dared tube amp. At least to me. Plus is that the Diamonds are wall mountable, so it takes up no desk space. Looks good in rosewood. . . order palang ako kay Jun.

"Tested that with a Trends amp at S&S and it actually sounded better vs the Dared tube amp."
what DARED tube amp model po ba ang na compare mo sa Trends sir? i was thinking to upgrade to DARED tube from a Charlize t-amp/Tono tube pre-amp combo. but kung maganda pa performance ng Trends baka same lang sya sa 12AU7 pre/t-amp combo ko.

I forget, but it was the topmost amp. Didn't get the model. Depends on your type of music. Kung dynamic yung passages ng music mo baka hindi kayanin nung trends, since its basically 15x2 din.
Baka gusto mong i-try din yung KT88 amp ko na for sale din. . . ;D
-
Can you give a short review of the kingrex t20u t-amp? How much is it at s&s? Read in reviews it sound like a tube amp, can you confirm this. Tnx :)
Not ches, but let me try.
Where: SS Shangrila
Speakers: B&W FS, 2.5-way (IIRC)
PSU: KingRex PSU for both
Music: Sari-saring love songs
Distance from speakers: Probably 1.5m away
Build:
No contest. KingRex wins.
Sound:
KingRex sounded soft, mellow. Trends has this "sparkle", I thought it was very nice w/ vocals. There's more emotion. The instruments seem more defined.
Also, I think the Trends has more gain than the KingRex.
If I was buying then, I'd take the Trends.
-
bumblebee, thanks for the brief but concise review. I guess too much hype on the kingrex then. ;D Only wish I can afford the red dragon or red wine digital amp! :(
-
To be fair, from the reviews I've read, TA2020-based amps are often used w/ horns or other highly sensitive speakers, with stable impedances.
As for Red Wine, 41Hz have Amp4 (Signature 30) and Amp11 (Signature 70) at a fraction of the price.
-
i read that the trends uses a different tripath chip to the kingrex. the tripath chip in the kingrex is more powerful than the trends. this may explain the difference in sound quality.
-
Thanks. Bumblebee
yes the trends and kingrex uses different tripath chips the kingrex has little more power, you have to audition the amps with the gears you have, and which amp will match. its subjective if which one is better. the advantage of the kingrex is it has a usb dac for pc use.
-
just like vanilla ice cream, offered by different brands that have different tastes... ;D

Just got my Trends TA-10.1 and Wharfedale SR combo for the office. Sounded really good sa showroom ng Sight and Sounds using my iPod as the source. Some of the salesguys were looking at the setup and saying: "boss pwede pala yan . . . " Can't wait to set it up in the office.
Just for kicks though, I thought of testing the Trends using my home setup. Thus, it was:
320kbps AAC music wirelessly streamed via my Airport Express to:
Setup 1: Lite DAC-AH--->AMX KT88 Integrated amp--->Castle Richmond 3i
Setup 2: Lite DAC-AH--->Trends TA-10.1---->Castle Richmond 3i
Music:
1) Hotel California (live)
2) Africa
3) Rosanna
4) Somos Novios (Andrea Bocelli & Christina Aguilera)
Observations:
1) For such a tiny amp, the Trends TA-10.1 sounds surprisingly big. Vocals are quite good on the Trends and it is capable of bringing out the details of the music.
2) Bass is a bit thin on the Trends, thinner vs the tube amp though possibly having a better preamp stage may give it more low end oomph.
3) Amp runs silent even with volume turned all the way up with no source.
4) Amp also appears to run undistorted even with the volume turned up. Had the volume at 9 o clock and the output was clean. But bass still thin even at higher volumes.
Verdict: initial listening tests seem to point out that the Trends sounds pretty good, though not quite enough to replace real serious audio gear. The tube amp still offers sound that's more full-bodied. The Trends amp scores well on details and vocal definition, but thinner bass makes its sound less appealing vs my tube amp.
Take note though that I'm comparing stock vs stock. A modified Trends or some of those souped-up T-amps may indeed give traditional components a run for their money, but that would remove the value for money factor inherent if one purchased a Trends T-amp.
In all, I'd say the Trends should be ideal for a small room or as an office setup. Sure beats having a set of computer 2.1 speakers. More expensive, but the sound is so much better.
-
nice review on the trends t amp, thanks.
-
been using the trends for about 5 months now with ipod as source and anthony diy floorstanders. the ease of choosing playlists from the ipod and the great sound of the trends have me neglecting my main audio set-up. a week ago, after stumbling across threads about connecting subwoofers for audio, i decided to experiment connecting my subwoofer which was gathering dust after i abandoned my HT set-up. used y connectors to split the rca from the ipod to both the trends and the sub.
i know im cheating but my sons love it when i play "low" on it now. they love the boom! on a whim, hooked it up to the tv and played music videos and concerts. hehehe very nice.
cant wait to have it modded by engr. ferds.

Sights and Sounds at Edsa shangrila carries both T-amps...i think the trends is priced around 6-7k while kingrex is around 10k+....been trying to find the time to audition both....for the serious audiophile, i think these two amps can give us a glimpse of the high end at a very cheap price. ;D

sir san po yung volume control nito? and what mods would you recommend?
wala sya built in volume control.. nasa syo nlang kung gusto mo sya bigyan.. Madali lang naman lagyan kung gusto mo meron.. or kung meron ka preamp na meron volume pwed na yun..
Basic mods eh tanggalin ung ibang resistors and caps sa input stage para bumaba ung DC offset sa output..
next mod kung me budget pa.. palitan ung input caps to polyprop caps and add atleast 10,000uf caps sa 12V supply.
;D

perfect combination siguro yang diy t-amp na yan saka yung mini3 mo! wag na lagyan ng vol. pot yang t-amp, yung volume control sa mini3 na. ok kaya yun? ;D

Semi OT
Friends,
My Sonic Impact T-Amp ver1 conked out several mos ago. I gave up on it since ung pinagbilihan ko sa megamall told me hindi nila sineservice yun kasi disposable daw. Nang hinayang naman ako at tinabi ko lang. Then I saw this thread and thought maybe someone can help me resurrect it. It still powers up but no sound. Naiwan ko na nakabukas ng magdamag and in the morning dead na. Is there still hope for this little guy? Sayang ang linis pa naman tumunog. I would appreciate thoughts on this. TIA.

@ferds-
maganda na dati tunog, lalo pang gumanda! tama ka immediately napansin ko nabawasan yung shrillness kaya gumanda yung highs. feeling ko lumakas din bass pero di ko pa napapakinggan ng matagal.
@lakambini
thats the trends t-amp. its an integrated amp, which you can also use as power amp by changing the position of jumpers. the picture shows modifications made by engr. ferds of ferdsaudio

guyz i'll buy a sonic t-amp tomorrow to drive my X3 FS, my power source will be from a Enermax power supply for computer. Any one comment with this pair?
I saw somewhere in Raon a Sonic for just 1,500. Palagay ko mura na kasi yung sa Mega 2k siya eh

*disclaimer - i did my pdvd search and found very little info regarding these.
This is a very interesting product specially for me who'd like to listen to good quality music on my PC.
Currently I'm using a Klipsch 5.1 Promedia on my pc and I'd like to go with a straight stereo setup.
I found the Trends T-AMP may work for me.
A couple of questions for you folks:
1. Aside from Sights and Sounds where is the best place to get this?
2. How much?
3. What are the modifications (saw someone refer to Eng. Ferds) that can be done with this and what are the effects
4. What speakers would work well with this? What are the specs I need to check.
thanks for your inputs
-
1. Aside from Sights and Sounds where is the best place to get this?
I don't know where else.
2. How much?
Around 7k yata.
3. What are the modifications (saw someone refer to Eng. Ferds) that can be done with this and what are the effects
The Trends is already a modded t-amp. What you can do is upgrade the parts to branded ones, like the input caps and pot.
4. What speakers would work well with this? What are the specs I need to check.
Get high sentisitivity speakers.
-
1. you can contact ches for the Trends
2. see #1
3. aside from the caps ek ek you can concentrate on the psu, perhaps a rechargeable battery source.
4. +1 to bumblebee's #4 answer.
but if you already have a pair of speakers and will use it exclusively for PC then why not consider the Dared MP5 which already has a USB dac and has a lot more kick than the Trends, consider the tubes as bonus features. ;)

I have the TA.10i model, bought from Watt Hi-Fi at Makati Cinema Square (forgot how much I paid for it) originally to match with a pair of 90db Onkyo vintage speakers for office use. It powered those speakers with a loudness that startled everyone who heard and saw it.
Out of curiousity I brought it home and paired it with my 86db, 6ohm Pacific Pi-10s, and darn if it didn't make the speakers sing! I dared not turn the volume knob past 10-11 o'clock for fear of the neighbors.
The amp itself measures 4.5" x 3" minus the binding posts and volume knob protrusions, and so light you can hold it up with two fingers. Really, I have no idea where it gets its power.
I have also plugged it to my pc's sound card. MP3s are no problem. The only times it showed some strain were with the audio of badly ripped mpegs and avis with very low volume levels. Even these did not bring it to its knees - just brought up the volume knob near 12 o'clock.
The only thing I have against it is, there is only one pair of rca inputs, so you have to unplug and plug every time you change sources.
Since it is so tiny and light, I suggest buy the Trends amp first, then bring it with you when you audition speakers. Somewhere I am sure you will find a perfect match.

I also had the pleasure of owning the Trends TA-10.1. I've tried them with the following speakers:
1. Wharfedale Pacific Pi=10 rated at 86db @ 6 ohms. These two-way bookshelfs with 6.5 inch woofers are in my opinion quite difficult to drive for the t-amp andid not brought it to good sound levels.
2. Vintage Pioneer CS-88. These are 3-way speakers from the late 60s. Big 12-inch woofers. Sensitivity is about 90-91db sensitivity in my estimate. Relatively easy to drive and the t-amp was quite happy with them. Nice bass, though a bigher amp would have better control of the big bass woofers.
3. Vintage Jensen Model-1. These are 8" full-range speakers in sealed bookshelf cabinets from early 70s. Around 92-93 db sensitivity in my estimate. Vesry easy load for the t-amp. A bit lean on bass but sounds really great on midrange. Good for female vocals.
In my opinion, the flea powered t-amp amp will shine on high sensitive speakers (unless of course you are contented at low volume listening).
BTW, in the marketplace, I saw a Klipsch RB-3. It's a two-way bookshelf rated at 94 db sensitivity. Perhaps a good match for the t-amp ;D

thanks to all the replies!
so what sensitivity rating range should I be looking at?
also, are there other stores (here or hk) that sell t-amps similar to the trends one?
how about that Dared MP5. Is that locally available? How much is that?
thanks again folks! You've been very helpful!

is it true that tubes need to be replaced often?
how frequent kaya?
thanks!

thanks!
on the MP5, the smaller ones are signal tubes, unless there is a factory defect, they should last long. the level display tube on the other hand may last a bit shorter than the signal tubes. but don't worry, you can find replacements easily.
-
how long do the tubes usually last? does the sound quality degrade after awhile? or does it suddenly stop working?
what characteristics should i look for in a speaker? what is a good sensitivity rating?
what would sound better? mp5 or the trends?
-

if those are the peanut tubes, 12au7, etc., they can last a lifetime.... ;D
-
so is it safe to assume it's superior to the Trends T-Amp?
What speakers would you suggest?
Also... what is a good listening position (distance, etc)? Will it sound ok even if the proximity is equal to that of regular PC speakers?
My main goal for this is to listen to good quality audio when I'm in front of my PC.
thanks so much!

Trends t-amp is a class D amp and Dared MP5 a class AB amp (they are both chip amps though), which one suits your tastes and speakers is more potently answered by actual auditioning of these amps. Preferably with your intended speakers if you can. If budget permits, get the highest sensitivity speakers available.
Bear in mind though that the Dared has a USB input that can be "more" suitable for your PC applications.
Speaker distance, toe-in toe-out is another story, search the discussions in this section for more detailed instructions.

Guys here, have you have experience with this gadget?
Cos this is getting good reviews from the web.
Please share your thoughts especially Ferds of ferdsaudio.com
He has this gadget.
Sir Ferds, may I ask if this could run good with Wharf 9.1 bookshelf speakers?
Or anyone could give an answer to this.
Guys please share experiences cos I think that this is a bang for the buck!

I owned the Trends TA-10.1 for about a year.
First paired it with a vintage 3-way Pioneer CS-88 about 90 to 92 db sensitivity, sounds really dood and can drive the 12" woofer at moderate levels. Then paired them with vintage Jensen Model 1 single driver bookshelves about 92 to 94 db sensitivity, sounds very good especially vocals and can play a bit louder.
Tried it with a Wharfedale Pacific Pi-10 with 86 db 6ohms. It had hard time driving the speakers. Not a very good combo to my ears.
The Trends is now with my office mate and he paired it with a Tannoy Fusion which to my ears also sounded good for moderate listening level.

Just got my Trends TA-10.1 and Wharfedale SR combo for the office. Sounded really good sa showroom ng Sight and Sounds using my iPod as the source. Some of the salesguys were looking at the setup and saying: "boss pwede pala yan . . . " Can't wait to set it up in the office.
Just for kicks though, I thought of testing the Trends using my home setup. Thus, it was:
320kbps AAC music wirelessly streamed via my Airport Express to:
Setup 1: Lite DAC-AH--->AMX KT88 Integrated amp--->Castle Richmond 3i
Setup 2: Lite DAC-AH--->Trends TA-10.1---->Castle Richmond 3i
Music:
1) Hotel California (live)
2) Africa
3) Rosanna
4) Somos Novios (Andrea Bocelli & Christina Aguilera)
Observations:
1) For such a tiny amp, the Trends TA-10.1 sounds surprisingly big. Vocals are quite good on the Trends and it is capable of bringing out the details of the music.
2) Bass is a bit thin on the Trends, thinner vs the tube amp though possibly having a better preamp stage may give it more low end oomph.
3) Amp runs silent even with volume turned all the way up with no source.
4) Amp also appears to run undistorted even with the volume turned up. Had the volume at 9 o clock and the output was clean. But bass still thin even at higher volumes.
Verdict: initial listening tests seem to point out that the Trends sounds pretty good, though not quite enough to replace real serious audio gear. The tube amp still offers sound that's more full-bodied. The Trends amp scores well on details and vocal definition, but thinner bass makes its sound less appealing vs my tube amp.
Take note though that I'm comparing stock vs stock. A modified Trends or some of those souped-up T-amps may indeed give traditional components a run for their money, but that would remove the value for money factor inherent if one purchased a Trends T-amp.
In all, I'd say the Trends should be ideal for a small room or as an office setup. Sure beats having a set of computer 2.1 speakers. More expensive, but the sound is so much better.
Sir have you tried the Trends 10.1 with the Wharf 9.1 please at 86db?
-
Sir where could we buy TA-10 Class-T Stereo Audio Amplifier here in Manila? Do we have a dealer in our country?
Try to contact Chester - 09178321727. He used to bring those in awhile back.
I used to have 3 of those original T-amps a few years back - sold all of them. I guess they were okay for $35 each back then, but somehow I felt they were just novelties. i'd recommend these Tripath amps for a 2nd or 3rd setup, but not for a main audio setup. These would probably work best for near field listening, hooking up to an ipod or maybe for amping computer speakers.
While they're inexpensive and less powerful, they will limit your choice of speakers. You must get high sensitivity speakers and those alone are hard to come by - much less if you really like the sound of what brands are available.
Your kind of music will also effect it's performance as some dynamic music can lower the ohms of your speaker which would cost distortion and ruin your amp & speakers.
These Tripath amps are 10-15watts at best and you'll probably be listening to near its maximum threshold just to get a decent amount/room filling sound. They're also not that flexible since they're small - not much input for other gears.
Speakers are at best when ample power is fed thru them and naturally, you also want an amp with a bit of headroom for those demanding musical contents. Those Trends amp would probably set you back in the vicinity of 8k and for that amount, I'd rather go for a preowned amp that could give 40-50watts. You could have a Rotel or Nad integrated for about 8-10k in the preowned market ;)

Hurrah for stock sonic t_amp 8)
Still have mine boxed & unused ... with matching SMPS of old laptops ... wag lang kalawangin! ;D
To add some more considerations of using T-amp. At rated 15w at 4 ohms, to be technically dynamic, use only 1/10 of the rated power (unless you know how much it can peak) - for T-amp at 4 ohms: 1.5W ; for 8 ohms: approx 1 W - translation: high sensitivity speakers to be loud enough to be enjoyed. Now that's green!

Yep, read that before I got my Trends TA-10.1 almost two years ago. :D
Note that they used a high sensitivity speaker. My feeling is that Wharfedales would not cut it. Maybe some Klipsch with greater than 92db sensitivity. Sights and Sounds or Spectra are selling them. Or Infinity Primus Series (avshop of this forum are selling them I thinks). Heard a Kingrex (another Tripath based amp) paired with Infinity Primus 260. Sounds nice!

Nice test ... I think anything with the T-amp IC there will always have a winner in it ...
But sonic T amp at USD 20 is something beyond imagination taking on expensive one.
A well-disciplined 97db full range will do a lot of justice to those miniscule amp
-
I had this before for m office setup. For the size of the amp, the sound quality that comes out of it is rather amazing. However, the low RMS output necessitates that you audition speakers that are well suited to it. I got mine from Sight and Sounds, they also have a wide range of speakers that you can try out.
That being said though, at PHP7k thereabouts, it's not that cheap, specially when you can get a used NAD320bee for about the same price. Or you can save up and get a NAD315bee for 15k.
The sound is amazing for the size, but unless you have space constraints, or need to have a stealth system, I'd advise you to go with a full size stereo amp instead. It's cheaper in the long run, and you will have a far wider range of speakers and accompanying equipment to choose from.

is this worth trying? or should i stick to my s.i. t-amps? ::) ;D

Hi Rene,
If I have extra money I would buy this especially the 55wpc with the power supply upgrade. Although I am happy with my modded dual T-amp but with the additional watts I would go for this.

I was first attracted to this audio hobby (being a computer hobbyist beforehand) after reading some interesting reviews on t-amp.
My first t-amp was a stock TRends Audio TA-10.1 using the same Tripath TA2024 chip as the original Sonic impact t-amp. Then had a chance to grab in the marketplace a Kingrex T20 for a good price. This is based on the TA2020 which at stock form sounds better than the Trends. With the input caps upgraded to Auricap, the Kingrex sounded much better. Well, not exactly tube-like but very good for its price.
The Vitrue amps look interesting. Well, they're out of stock at the moment.
The Poppulse T150 based on TA2022 rated at 75wpc which sells for $239 at diykit Hongkong also looks interesting.

to my ears (only), the Pop Pulse has a more transparent and sharper definition in the top end, where the Virtue Two seems to have a larger soundstage, better bottom and better imaging.
But my Pop Pulse T150 is modded by a friend, including replacing the orignal elna electrolytic caps with MIT caps

Hi Cal,
Nice alternative but the virtues would have an edge in driving more speaker types and impedance ranges. With the virtue you need not find high efficiency speakers as the 55wpc is more than enough.
Likewise, maintenance is simpler....no hard to find tubes to worry about.

Anyone here owned or listened to either version of this? Im intrigued by it, thinking of using it for my PC. Currently using a JDLabs headphone amp, minijack-to-minijack from PC HP out. Im contemplating on keeping that for my bedside CDP, along with the K66, and re-do the PC set-up. Planned upgrade will be this amp on TangBand 4" fullrange drivers in custom MDF ported enclosures and AKG K99, whichever I use for listening, gaming or movies.

Is there a way to connect a conventional amp's amp speaker output to a headphone amp terminal? I saw a thread where you can gut a headphone cable (adviseable only for really cheap units or expensive units with detachable cables) to connect to the speaker outs, just want to save myself the risk of shorting the headphones, and also have the capability to use the amp with other cans. If it's possible, planning to have an SI T-amp re-wired, plus get a custom PSU (like the ones on laptops) for it. Anyone tried or contemplated this?
-
Good day guys, currently I'm looking for a store to buy a Trends Audio TA 10.1 amp because Sights N' Sounds has no stock as of this moment. Do you know a store who have this kind of amp for sale? Please share to me. Thank you. :)

in preparation for the arrival of obami*, "ate V1" amp (will be used as 55watts bridged "mono"); i hooked up dual sonicimpact stealth-mod t-amps as "monoblocks" w/ non-biwireable infinity primus 160. T1 to drive left speaker T2 to drive right speaker. cdp as source, no tubepreamp used. since the t-amp is already bridged, it utilizes ta2024chip's 15watts for each speaker; unlike if used as standalone t-amp(5-6wpc) for 2 speakers.
kayang-kaya idrive ang 90db/8ohms primus160 with lots of bass but still retaining the mids and hf excellence!!!
*maraming salamat uli sir raygun :)

Now the THREE...
(http://i15.photobucket.com/albums/a385/jron1997/v3.png?t=1254529280)
- Want to buy two amps to run as monoblocks? Don't.
- Completely dual mono amp with a special power connector that allows you to hook up 2 power supplies.
- Separate power routing to left and right channels.
- Can be run on 1 or 2 power supplies. Switching from 1 supply to 2 is internal and automatic
- Good, solid 130 wpc into 4 ohms.
- This unit can supply so much power we put 2 heatsinks on it and it sits on its side.
Hell on wheels in the same small box.
- Same great upgrades as the ONE.2 and the TWO.2 but with dual mono capability
- Tellurium copper binding posts and RCA connectors
Now the ICEBlock.. (maliit lang yan!)
(http://i15.photobucket.com/albums/a385/jron1997/viceblock.png?t=1254529320)
- Killer Class-D monoblock based on the ICEpower ASP500 module.
- 500 Watts into 4 ohms
- 115dBA dynamic range
- Damping factor over 1000
- Big, powerful, masculine bass (if you know what we mean)
- Built in power supply 120V or 240V
- Custom balanced XLR or unbalanced RCA inputs, selectable
- Buffered RCA loop out
- Accurate and analytical
- Same form factor as Sensation amp and Piano CD player
-
I've been out of cirulation - can anyone recommend a pair of high sensitivity but cheap speakers for a sonic impact t-amp?
thanks

@5k max. range only speakers that i can think of are vintage pioneer, sansui etc or daii klipsch-clone 93db.
i wouldnt even recommend my infinity primus160 90db easy to drive but good only for dual t-amp (one t-amp/speaker) not single t-amp. imo, 95db+ speakers are best for t-amps
-
o.t. lang sir ojof00l, available pa ba daii klipsch clone sa market? where can we get one and how much? ::)
Meron ba satin locally available na class d amp with icepower modules? Tnx :)

Looks like a new phase is dawning at least sa 'digital' amps. NAD M2. Available na kaya? Kaya lang 4K usd.
Walang analog amplification pag ginamit mo digital input, all digital signal path. Hindi na DAC, kundi PCM to PWM converter, maging PPC kaya ang tawag sa?

Mike ganda niyan ah! couple of questions for you if you dont mind. ;)
parehong pareho bayung board layout nung dayton sa original na sonic impact? tsaka bakit anim yung banana plugs?
lastly musta sound after the stealth mod? ;D
-
thanks, ivan. :D
nope, it's not the original version, v2 na ata ito. the components (resistors and caps) para sa stealth mods are on top (chip side). hanapin mo yung picts nung kay audio1st sa diyaudio para makita mo kung saan yung mga smd na tatanggalin. :)
it sounds better imo. yung bass di sya boomy, mas defined na sya ngayon. dati kapos yung bass (di bumababa) pero boomy (malakas yung upper bass range). kailangan talaga sa kanya 89db and up na speakers, bilis nyang mag clip. hehehe
the extra 2 binding posts are for the power section para pwede iba-ibang sources. i'm burning it in now using a sealed lead acid battery na may charger na naka parallel. :D
-
^ sir san ka nakabili ng ferrite rings? other sizes available? tia
madami sa bangketa ronquillo quiapo at eleshop ronquillo din parallel sa raon.
@sir caohyde, do you accept dayton t-amp stealth-modification job?
-
sir ojofool,
in as much as i'd love to mod your amp, it was a freak day and i had time to do it. unfortunately, wala masyadong free time these days. it's actually a bit easy if you're handy with a soldering iron. yung layout lang ng new components and mounting ang mahirap dun.
cheers!

i used sanyo caps instead of auricaps or blackgate (low budget eh. :D) for the signal and stiffening caps, pero meron mga solen sa amx in rob pioneer around p320 each iirc.
sonically, imho, okay sya for jazz vocals and near field listening. if you want a bit more oomph, you'd want to stick with high powered amps or mag bi-amp ka with active crossover. use the t-amp for the mid-highs crossed over at ~80hz tapos sub should play a bit lower. i'm experimenting with car audio stuff now for this. :)

Tale of 4 t-amps
I have the opportunity to own the following:
1. Trends Audio TA-10.1 (stock) (around 6wpc)
2. Kingrex T20u (upgraded with Auricap input caps) (around 8wpc)
3. Virtue Audio One (around 30wpc with standard power supply, 55wpc with upgraded power supply)
4. virtue Audio Two (same rating as Virtue Audio One)
The Trends TA-10.1 (SRP $150) uses the same TA2024 chip as the Dayton (SRP $60) in thick aluminum casing, standard RCA inputs, standard speaker binding posts and 36VA power supply. The Kingrex T20u (SRP $260) uses TA2020 chip with USB input. Built quality is better than the Trends. Stock power supply is similarly rated at 36VA. The Virutue Audio One (SRP $270) and Two (SRP $380) have better built quality than the Kingrex. Virute Two, compared to One, uses Auricap input caps, higher rated supply/power caps, and better binding posts/RCA inputs. Both uses TC2000 as processor and one power chip per channel (TK2050 for One and DX2100 for Two).
Soundwise, all t-amps are more similar than different. Detailed, transparent, neutral. My vintage SS amps (Sansui AU-D907F, Trio KA-7300) sounded less detailed compared to them. Sir alexg's KT88 SE amp (around 8wpc) seems more tranaprent and detailed though than the t-amps Of the four t-amps, the Kingrex seems warmest, follwed by Virtue Tow, then Virtue One, and Trends is brightest.
With Fostex FE167 full-range drivers in Half Chang speaker enclosure (94db) even the Trends TA-10.1 can drive them to reasonable loud levels. With small mid-sensitive two-way bookshelfs like PSB Image 1B (89db) and Tannoy Fusion F1, the Trends seems OK at low-moderate volume. The Kingrex is fine at slightly higher volume. And with hard to drive two-way bookshelfs like the Celestion 100 (84db), Celestion 3000 (86db) and Dynaudio Audience 52 (86db) the Trends and Kingrex are understandably inadequate.
Both Virtues can drive these speakers to reasonably loud levels
Virtue One and Two are almost similar, though the Virtue Two seems slightly better in all sound departments. Both sounded better with upgraded power supply.

Virtue One and Two are almost similar, though the Virtue Two seems slightly better in all sound departments. Both sounded better with upgraded power supply.
for me, virtue one +90w psu is the best all-rounder since its 30wpc drives dynamic speakers well.
but with my speakers, the stealthmodded sonic-impact t-amp used in dual-mono config is best. at the price point (and even higher), mids and hf is excellent. caps used are a pair of aerovox 2uf and a pair of mundorf supreme 2.2uf for each t-amp.

Hi Sir ojofool, musta na? OT: I got the V2 from Sir Raygun just last Monday. Had a nice chat over cup of coffee. Perhaps I'll keep both V1 and V2 muna. These are keepers. ;D
What I find common to these t-amps is that they seem to need long break-in. Even Sir Raygun;s V2 seems not fully broken in yet.
Also t-amps seems to respond well with input capacitor upgrade. When the input caps of Kingrex was upgraded from Bennic to Auricap, the improvement was not suble at all.

kung hapi ka na sa soundquality na naririnig mo, well and good!
imho, stock t-amp very best match with 96dbup speakers. best with 93db speakers.

tnx sir ojofool! try ko muna sa mission ko n MV4 ung dayton T amp 15wpc, paghrap tlaga kailangan ibenta cguro ung MV4, ang magandang match yta dun s t amp e ung paradigm atom V5 according to forum. mhirap n kc magkamali pagdating sa sounds....dpat may payo ng expert. ;D

Sir ojofool,
ganito din plano ko sna. parang mono block style sya. 1 T-Amp for each speaker. Paano mo ginawa? pede pa share naman kahit sketch drawing lang.
one more question is, ok lang ba one T-Amp is Sonic Impact and the other one is Dayton? wala kayang problema sa SQ?
TIA,
edocampo

Hi Guys,
Try ko lang sana ask dito kung may nakapagtry na ng units ng hifimediy? Here is the link of his site http://www.hifimediy.com/The_amps.html
He can also be found on ebay and DIYaudio.com, mura yung mono config niya as well as stereo boards and already assembled so power supply, connectors and casing nalang kulang.
What do you think?
Thanks,

With those 4 tubes, I don't think it can produce 80 watts as a vacuum tube amplifier.
It might be similar to the Sakura, a hybrid amp.

Is it possible to have the volume knob of the Sonic Impact T-Amp replaced? I haven't used mine in quite a long time and when I started using it again this week may static na sa right channel whenever you turn the volume up or down and sometimes humihina din yung right channel. But if I press the knob the sound equalizes.

Is it possible to have the volume knob of the Sonic Impact T-Amp replaced? I haven't used mine in quite a long time and when I started using it again this week may static na sa right channel whenever you turn the volume up or down and sometimes humihina din yung right channel. But if I press the knob the sound equalizes.
you can do the following:
1. rotate the knob back & forth several times. can dislodge dirt inside.
2. use contact cleaner to spray the potentiometer contacts and do #1. kung na-stock lang ang amp i'm pretty sure this would work.
3. if 1 and 2 doesn't work, replace the potentiometer. you can choose a cheap pot, an alps pot or a stepped pot depending on budget and preference.

im considering buying a Dayton t amp to be use as fronts for my wharfedale 9.1 . ht setup
pros.... cons...?
thanks in advance
-
I think there is an existing T-Amp thread.
Anyway, the biggest drawback of this amp (DTA-1) for HT use would likely be its low power level. It might not match the receiver's speaker outputs in terms of volume and headroom.
If you're looking at Dayton products for that purpose, the DTA-100a (or the APA150) may be a more suitable match (granted that your plan is to shore-up the performance of a system based on a weaker receiver).
-
sir 2 channel HT setup ba or your planning to run it through the recievers pre outs?
Just to answer your query re pros and cons id say the biggest drawback definitely is the power handling ( Dayton DTA-1 ) you can get to decent volumes but definitely not cinematic, other than that cant really think of anything else, some positive points are cheaper electricity, small footprint, AMAZING soundtracks and clear conversations...
i'm just speaking through expirience. ;) HT ko kasi is located sa Pampanga, i've been staying recently at my wifes house... so recently i've been watching a lot of movies through my computer... gamit ko yung Dayton DTA-1 sa computer ko coupled with a pair of bookshelf speakers... temporary setup for listening to mp3s and watching movies, quite happy with it. ;)
-
i see... its nice to get some ideas from you guys... when it comes to architectural compare to a class a or ab type ok naman? planning to use its as a up front for a ht setup.. so t- amps are considered as a class d amp? ksi if you say na you need to upgrade internals like capacitor it just means na it need to have a good supply of electricity to juice and to give more power... only difference form a class d is cleaner output and staging?
hehehe ;D
leaning to tube... ;D

Ang sinasabi ng marami ay depende sa power supply and total current and power na maibibigay ng amp. Subukan mong pakinggan ang T-amp tapos isang vintage receiver na pareho ang power rating, gamit ang pangkaraniwang speaker na katamtaman lang ang efficiency. Maririning mo na mas buo at mas malaki ang tunog ng isang lumang amp laban sa T-amp. Nagkakatalo sa power supply.

Sir,
I wanted to setup upgrade my sounds for my pc but i'm hesitant to invest in a receiver. How would you make a 5.1 setup using your setup? or is it cost effective pa rin to invest a budget receiver?

sir kung 5.1 dabest parin kung reciever,,, abang abang ka lang dito sa market place... :)
-
I assume kaya mo gusto mag 5.1 is for movies.mag receiver ka na lng sir, t amps are great piece of gears no question about that. But mas ma enjoy mo yung movie experience mo kung receiver na gagamitin mo.mas simple ang connections, plus yung mga features na meron sa receiver na wala sa t-amp.
marami pong receiver sa market place i'm sure makakahanap ka ng pasok sa needs and budget mo.
happy hunting ;)
-
@kemozavi: Thank you for your reply. post ka naman ng pics ng laptop setup mo ngyn. or nasa youtube ba? Txt kita pag bibili ako ng t amp for a separate simple audio setup!
@Euphony101:
Thank you for your input! Will be buying a receiver for my pc. as it is more cost effective.

i am ordering a set of Shure calss T amp, i think this issue is psu related, remember that power rating for T-amps will depend a lot on your power supply, give your T-amp a psu that it deserves and i believe it will go places.... ;D

Sir, with regards to sure class t amp, it's says na up to around 30v need nyang power supply to maximize it's potentials, where can we get a commercial type plug and play 30v psu? Or is it a diy thing lang. Tnx :)

What the difference between EI traffo based psu and smps type psu? and the diiference it will make to a t-amp sound like sure? ;D thanks
the EI traffo based psu will be a lot heavier about 4 to 5 times heavier, will have higher ripple voltage and poor regulation, the smps will be lighter, lower ripple and better regulation.
cost will be about the same, you can get two 300 watter branded atx psu's put the 12volt rails in series and you are good to go, this is the cheapest solution i can think of.....
if you opt for the EI traffo solution, you will need at least a 300VA power traffo, with a 22volt x 12 amp secondary, a 35ampere FWB rectifier, and about 4 x 4700ufd/50volts electrolytic caps, 1 x 470ufd electrolytic cap, and 1 x 0.47uf/film type cap.
sound will be determined by low ripple and good regulation.....

thanks for that sir TonyT, wala kasi ako makita dito sa amin na ready made PSU, so EI traffo is the solution,
saan ba pwede makakuha ng schematic for EI traffo? salamat
-
if you want to go EI, get the biggest 12-0-12 traffo you can afford, traffos is Raon will be over rated anyway...

that 24v/10amp psu looks very much similar to the one sold at e-gizmo......
up to a certain level using a smaller psu and that psu, the sound may not be all that different in terms of level, the difference will be when delivering transients and loud passages, this is where the big psu excels....
imho..any amp can only be as good as its psu....if that module cost almost 3000 pesos, i will be more than willing to spend the same amount on the psu.... ;D
-

thanks! ;D
i am going by the specs of the Sure amp itself, 200watts with say an efficiency of about 85% will require a psu of about 240watts, that is why that psu from E-Gizmo surely fits the bill....current draw will depend on program material and how loud you are going to play this amp, and of course the speakers that will be driven by this amp....
i am looking for documentation on this amp, i am busy with something else at the moment....
but you can even use some of these laptop psu's, just observe proper polarity....

Sir,
my sub doesnt have output. only lfe input. +-R and +-L input and RCA mono input (Mirage Omni S8).
This will not do harm to my T-Amp(lepai)?
I am currently spliting the source < tamp
< Omni S8 (filter on) (using mono RCA )
But i dont know if this is optimal.
Thanks a lot.

Can i just connect the sat speakers to the input of the sub? parang series.

or parallel nalang?

or just go on with the split source connection? (Problem is separate volume control. You have to adjust volume on the amp and the sub separately.) :)

Is it safe to parallel the powered sub with the speakers? By the way i am using the lepai ta2020 t-amp with wharfedale diamond 9.1 speakers and omni s8 sub.
-
Update lang re:sub connection.
Was able to connect the sub in parallel to the speakers using the lfe connection to my lepai T- amp. My sub now has volume control via the amp.
Medyo masikip lang masikip lang connection sa likod ng amp because i am still using the spring connections of my stock lepai t - amp and using high gauge speaker wires.
Next step upgrade my t-amp to use binding posts.

Sensitivity, power and impedance is no problem, it's the sonics or actual sound that will dictate kung bagay.

Sensitivity, power and impedance is no problem, it's the sonics or actual sound that will dictate kung bagay.
I hope what you meant was a high sensitivity speaker does not guarantee a 100% match.
Sensitivity is an issue with t-amps since power is low. Hence, it is best served with high sensitivity speakers to maximize the few Watts it can produce. Though impedance may not be a problem as long as you are within 4 ohms limits.
Of course no one can live with sensitivity alone, it is the overall sonics and system synergy that gives us the audio nirvana that we all crave for.
My few cents... cheers!

Based on my experience (and also Rex of Watts HiFi) the T-amp will sound loud with high sensitivity speakers like my Klipsch RB 61 II. However the sound was not good, it was a bit shrill actually. The T-amp actually sounds better with speakers in the 86-87 level like my JBL S-26 and the Wharfdale 9.1. I'm not sure though if the better match is due to the warm character or the lower sensitivity of the Wharfdale though my JBL cannot be characterized as warm it has a mildly bright sound but it sounded a whole lot better than my Klipsch. That's why testing the speaker out with the T-amp is the only way to know.

I'm sure the t-amp can drive that sir.
Based on my experience, most t-amp destruction was due to use of too low sensitivity speakers. Bring your speakers for auditioning sir, should be the best way to be sure.

Tanong lang sa mga owners of budget Dayton T-amp and fully upgraded T-amp being sold by Capital1.
Almost the same price kasi sila eh.
Which one is better suited to drive A-audio Genesis?
How far can I bring the volume? 12 o'clock ba? or can I bring it up further?
thanks

Sir juancho, ano po ba sensitivity nung A-audio genesis?.. by the way i'm using dayton t-amp.. as per sir otep of watthifi and sir ivan (kemozavi) na rin, the t-amp can drive 87+ sensitivity speaker.. i'm using it sa rti A3. so far, i can go up to 2 o'clock and so far wala naman naging problem..

^ Ok thanks, the Genesis is 89db :)
Any more inputs would be appreciated.

Was able to audition the DTA1 with Wharfedale Diamond 9.1 (sensitivity 87db) and Paradigm Atom v5 (sensitivity 89db). Yes, the DTA1 can drive either one, even the less sensitive 9.1, and pretty loudly for a small room at that. This was with the NAD CD player connected and some tracks from their 24bit copy of Best Audiophile Voices 2. Not as loudly, but not too far off, were some audiophile tracks playing from a friend's ipod. Audio gain was not as high with the ipod, but the amp could play the music, too.
Small wonder that DTA1. Hehehe! Would've pulled the trigger and gotten one since it was relatively cheap, and could power good speakers, had I not heard the Atoms being driven with about 40w per channel, that is. But that's another story, hehe!

I have the Sonic T amp which I believe has around 5wpc. Given its low power rating, I tried using it with speakers rated at 82db, 15 ohms. At a volume of 11:00, sound was quite sufficient from my sitting position of about 13 feet from the speakers. Additionally, the sound quality was more than I expected from such an inexpensive integrated amp with very low power.
-
Was able to audition the DTA1 with Wharfedale Diamond 9.1 (sensitivity 87db) and Paradigm Atom v5 (sensitivity 89db). Yes, the DTA1 can drive either one, even the less sensitive 9.1, and pretty loudly for a small room at that. This was with the NAD CD player connected and some tracks from their 24bit copy of Best Audiophile Voices 2. Not as loudly, but not too far off, were some audiophile tracks playing from a friend's ipod. Audio gain was not as high with the ipod, but the amp could play the music, too.
Small wonder that DTA1. Hehehe! Would've pulled the trigger and gotten one since it was relatively cheap, and could power good speakers, had I not heard the Atoms being driven with about 40w per channel, that is. But that's another story, hehe!
bro imagine that the dta-100a has an even smaller footprint. ;)

recently found out that the original sonic impact and the dayton dta-1 are coming out off the same factory, the dayton just has a different board layout plus a couple of upgraded parts... but man those original sonic impacts are like collectors items already... its the amp that started it all... :)

Wow, monster power from a T-Amp!
-
^not only T-amps, but other amps as well that uses either a torroid or an EI transformer...
-
now thats impressive 1000+watts @ 4ohms bridged mode, :o at that price point you can get two and play them on dual mono. 8)
wonder how they sound though... sa mga nag "momobile audio" this should be a pretty good alternative, small footprint, monster power, and monster savings on electricity.
I should probably request for a sample from the suppliers. :D

can you pls post prices?
im using sure tk2050. ive also used virtue audio One amp in mono-mono-config. nabasa ko na sa net yun arjen helder amps mukang maganda, tagal na mabisita nga uli....
im happy with my sure.
imo, malaking bagay ang power supply. yung virtue One stock psu 24v pero nung ginamitan ko ng 30v wow hataw! pm mo si Ka romymartinez, siyang nag-eenjoy ng virtues ngayon
-

+1, get the best possible PS. :) i've tried the ones from Sure Electronics and Dayton,,, both of them sound pretty good. :)
i haven't tried the other kits that you've mentioned but I like how sure electronics makes it easier for their consumers to build the kits... there are tons of tweaks for their tk2050 board, they have their own power supplies and they have rotary volume controls that are easily integrate-able with their existing kits, tried and tested narin yung protection circuits nila and almost all connections/installation faults are covered. :)

salamat mga sir. based dun sa diyaudio thread may mga issues with meanwell smps. initially iwas contemplating i-diy yung TA2020 na charlize2 pero masyadong mahal.

Yup, it's a very powerful amp for the price. The PSU is also onboard, so that makes assembly a lot simpler. :)
Dual Mono with 1340W per side. ;D Parang mga high end amps ang rating (I'm not saying pareho ang SQ). Pwede din ito sa mga DIY sub builds, as that power is more than enough to drive massive drivers.
Keep us posted about this, kung nakakuha ka ng sample. ;D

oo nga bai. umusok kasi ang trafo ng tono tube preamp ko kaya di ko muna ginamit. mas gusto ko ang tunog pag may tube preamp kasi. ipapagawa ko muna ang preamp bago gamitin uli. at saka, wala na akong speakers, binigay ko ang wharfedale evo sa kapatid ko. hanap pa ako ng proper speaker para sa t-amp. anong suggestion mo na high sensitivity at di makakabutas ng bulsa?
-

It might not be as robust as linear solutions, but Class D car amps have been using a similar config for sometime now. I'm hoping that these would be at least nearly as reliable (to think that car amps would have to live with more mechanical stresses). Many portable PA and SR amps now run with this design.
wait PSU is onboard na pala? so your supposed to connect this to the mains? this amps is a steal... :o hmm... i'll update you once I get a hold of the sample.
Yup, it gets power straight from the mains. :)

thanks po sir conan for clearing it up.
yung t-amp po ba pwede isubstitute sa receiver? kasi may kahinaan po yung output nito hindi po ba mahirapan yung speakers or yung t-amp? anu po ba yung tinitignan sa speaker matching sa t-amp yung wattage or yung sensitivity?

There are T-Amps which are higher in power like the Topping TP60 that I bought recently and si Kemozavi may parating na DTA-100A na powerful din. But even the smaller ones can give quite satisfactory loudness, you just really have to audition to be sure.

sir are those available locally, magkanu po kaya yung inaabot ng mga yun? powerwise it's a step up sa ta2020 and ta2024, pero yung sound quality po any changes or improvements?
yung dayton dta-100a maganda yung itsura brushed aluminum na ata and small form factor pa ren which is good :)
may nakita akong vid sa youtube ng dta-100a, although di naman review ng product yung nakita ko, parang demo lang link below:

Bro if you're interested in daytons kemozavi have them DTA1, DTA100a, APA150.. I have the DTA100a very nice sounding indeed... here are some of my vids so you can have an idea how the tini winnie amp can power a 86db speaker.. ;D if you can't see the amp it's the one with the blue light.. No magic bro just the DTA100a and ipod as my source.. ;D

yup bro ZIGGIES!!! ;D but im going to build a few boxes to try which enclosure will fit best.. My next is a double bass reflex for the merrills.. Love the sound of the merrills bro! ;) not cheap but what the hek if thats what im getting im good... ;D

bro, ive seen the videos! galing, kaso parang walang bass sa video, pero knowing na sa isang pares lang ng karton nakalagay yung merill, thats enough to impress me, i may post a clearer video of my ANs powered by tp60. ganda talaga ng sq ng mga t-amps especially yung dta1 and dta100a, though aiming for tba-g pa rin before the end of the year!

sid,
wla tlaga syang bass due to its enclosure the boxes vibrates like crazy! ;D I'll give updates as soon as my boxes are ready.. But so far it sounded really good im a bit exited to hear it mounted.. I strongly agree bro T amps are champs.. I orderd a Topping TP10 MK4 its actually here na im just waiting it to be delivered at home.. :) i'll make a few mods myself after burning it in for a few weeks and see what magic of the mods can do..

Goodluck on your new project carlo, yung mids ng mga merrils sounded really good on video, panget pa ng kahon niyan ah. ;)
anyway mukhang nagiging trent na ang mga gumagamit ng T AMPS mga fullrange speakers ang ginagamit ah.

Oo bro I was supposed to, kaya lang naisip ko baka mabitin ako sa bass sa w3, tapos I encoutered nga yung mga Pointsource full range speakers from daytons, so I ordered them together with my latest shipment. :) for now i'm just playing the waiting game. :)

3" medyo ma bibitin ka sa bass even sa 4" but it can be compensated sa box but still na kakabitin.. Unless na horn ang enclosures.. Anyway bro good luck sa mga projects m.. Oo nga pala bro do you have new kind of T amps other than the dta 1 and 100a?

i got 2 choices bro 1 is the zigmahornets and it goes well with the merrills.. 2nd is a double bass reflex design which complements any 4" drivers to bring out the bass any way i will make both to see what will fit best.. I still have a bose Fullrange to be used sa DBR.. I can send the plans for the double bass reflex if you want.. 8" its best to use a bass reflex designs but find a proper size for it..

if you dont mind carlo pakisend yung plans. :) are the measurements standard or are still computed based on the TS parameters of the drivers?
-
@ Ivan and Carlo: The cabinet Double Bass Reflex plans were already with my friend, a carpentry hobbyist. But before that I modify and got some design esp.the port flare from Omega Super 5 XRS. It's a little bit risky, coz, it's an experiment to combine ML TL of Omega and Double Bass Reflex design. The only difference is the port size and type.
We'll see if what will be the SQ after its completion within 2-3 weeks. I still use the Bose HVC from Carlo. Btw, I just want to inform all newbies on tripath amp to please break in at least 200 hours your tripath amp. It's too early to judge its SQ and performance if you haven't finish the proper break in period. My Dayton DTA 1 was at first thin sounding. But now even without the tweaks I made, the SQ of Dayton DTA 1 got better after the long break in period.
Here are the results after 200 hours break in period: (It's not a myth)
1. Sibilance was gone.
2. Soundstage became wider compared to the soundstage at 1st hour which was small.
3. Better clarity than fresh from the box. You almost hear everything in the CD recording such as, silent but clear conversation of the musicians while playing and others such as coughing, the "ehem" sound before the vocalist started to sing esp.during live session. Of course, you can't hear what I heard if the tripath amp is NOT properly match with your speakers (ideal is 25-30W RMS with sensitivity of 94db +) and also, your speakers must have better xover or no xover (pointsource type speakers/single driver). The speaker cabinet if D.I.Y must also be good.
As per experience, I am happy and satisfied with tripath amps esp.with TA 2024 chip (ANALOG SOUNDING). Amazing. I left Tube amp and Solid State for the SQ and performance of Tripath. The details and clarity of tripath are better on my ears. Though, dynamic of a well designed Solid State and rawness/decay of a well designed Tube amp are still the best.
Thus, enjoy music and have an open mind to accept new design/technology in 2ch audio, as long as the SQ is good or better than our audio gears and as long as it is analog sounding (like vinyl). :)

Hi Carlo, yung Dta100a mukhang may mga tweaks na ah... remember before you were asking me for upgrade options??? i remember si shrek7 (sidney) was also asking me how to upgrade the amp... ngayon may mga nag uupgrade na... 8)
calling brader ramon, please explain. ;)

Agree for TK2050! I upgraded the TK2050 (my friend's) DC Power cap to higher value... you will forget that you listening from a very small amp. Grabe pagka life like ng soundstage and mid. Nabusog ang AN Super 8 ko. :)

Alam na ni Carl iyon. Kaso iyong nadagdag lang was the use of a lower value oil cap bypass on DC power cap. Later i will post pictures of my dta 2 (TA2024 chip) project. Also, if given an a chance I will post pictures of my tk 2050 project. Masaya ako sa Tripath talaga esp.after this power cap upgrades. Thanks Carl for your suggestion. Nabuhayan ako ng dugo kasi kapag mataas ang value ng power caps nabubuhay din ang soundstage ng tripath...esp.with Mang Geri's oil caps.

how's the lifespan of these t-amps? i seem to read on the net that the problem with these budget t-amps are that it's hit or miss in regards to quality. how reliable are they and is it easy to have them fixed?

Here is my unfinished Dayton DTA 2 (Tripath 2024 module) from Ivan a.k.a Kemozavi, that I assembled with EVOX RIFA PEH 169 2200uf 63v x 2pcs and bypass with .0047uf 400v Aerovox caps all from Mang Gerry. Since I am just a hobbyist and not a technician, I just use my ears and a little faith that the amp will work and will sound as I expected. Still, in the breaking in period, the amp sounded very good to my clean ears. Sorry about the video resolution. This was my old Sony Handycam.
Here are the pictures with videos to check sound quality and have some idea how tripath 2024 rock my world late night, with just a simple DC power cap upgrade (if that's the right term). Details, soundstage etc. were all enhance and very natural. My PSU is CD R King M series multi voltage PSU (12volts - 24volts 4A max.)

Details, soundstage etc. were all enhance and very natural. My PSU is CD R King M series multi voltage PSU (12volts - 24volts 4A max.)

SALAMAS este SALAMAT -shukran!. Tatlo na tayo ni Carlo na in love sa Tripath 2024. Iba talaga lagapak at bagsak ng bass lalo na kapag na upgrade mga caps. Pero, gusto ko isunod for final tripath ko ang TK2050. Ksi nauna ko na upgrade caps ng friend ko kakabili lang kay Ivan iyong DTA 100a. ELNA CEW 2200uf 50v (1pc.) bypass with .0047uf aerovox oil cap (1pc) ang ginamit ko lang. Grabe busog na busog ang Audio Nirvna Speakers ko. Gumanda ang soundstage at details at lupit ng layering ng frequencies. Iyong 2nd voice sa Opera na "Habanera" ang linaw pero di na matalim after 2 hours palang na break in.
Satisfied na talaga ako sa audio. Ito lang nakayanan ko pero masaya na ako. :)

Here is my unfinished Dayton DTA 2 (Tripath 2024 module) from Ivan a.k.a Kemozavi, that I assembled with EVOX RIFA PEH 169 2200uf 63v x 2pcs and bypass with .0047uf 400v Aerovox caps all from Mang Gerry. Since I am just a hobbyist and not a technician, I just use my ears and a little faith that the amp will work and will sound as I expected. Still, in the breaking in period, the amp sounded very good to my clean ears. Sorry about the video resolution. This was my old Sony Handycam.

Thanks for your comment. Likewise, for bringing DTA 2. Ang daling kasing gawin pala. Yes bro! Excited kasi ako kaya nagpuyat ako dahil di ko massikaso kapag awake mga alaga ko. Yes, the PSU is better and maganda pagkagawa ng M series nila. Dahil binuksan ko. Mas malinis bro at malaki ang tunog. Tapos nag bypass pa ako ng isang .0047uf na oil cap sa isa sa dalawang DC output cap ng PSU kaya mas gumanda talaga. P 500+ lang ang price ng CD R King M series multi voltage. Yung difference from stock Dayton DTA 1 from DTA 2 with power cap upgrade was so big. Details and soundstage get wider and life like. Also, the gain was increased. I did not experienced any distortion. Ang linis bro ng tunog kapag maganda ang power cap mo. Hindi lang dapat mataas ang value. Dapat may quality din. Kapag wala, di ganun ka detalye at kalinis tumunog. Soundstage at details ang talagang nag improve. Napakalakas na ng 1 o'clock vol.level compared to stock na detalyado pero manipis. I really would suggest to upgrade first the DC Power Cap of tripath before you go with input caps. Parang sa power cap improvement lang sulit na bro. Pero kung gusto niya talaga mag hot rod ng tripath amp, matrabaho. Sa mgat tech guy, panis yan. ;D

Bro.i just replace the DC power cap of DTA 2 with EVOX RIFA PEH 169 2200uf x 2. Kay Mang Gerry lahat. Mayroon pa doon. Kaso you have to use a new housing for your amp sa laki niya. ;D

bro try Panasonics FC 2400uF sa supply caps m.. Then use the battery compartments for input caps.. Max out na ung dta1... :) since na 1 lng ang power caps ng dta1 its ok to use one 2400uF its sufficient but if you really want more no problem you can parallel 2 caps.. As per mesurements 1 2200uF will give you flat bass response down to 30Hz.. It will give you more bass more soundstage more channel separation..

EVOX RIFA PEH 169 2200uf x 2
do you really need 400volt rated caps in there? there are lots of other caps at the Raon sidewalks, 50 volts dc caps are aready big for this application...... ;)

Tama! Tried and tested na yan. I tried other cheap caps with high value, pero iba pa din ang tunog ng may quality. It's like Samsung LED TV vs. Coby LED TV, mas malinaw ang Samsung. :)

flat down to 30hz, mukhang maganda yan ah... :) kapag ginawa yung tweak na ito at inaalis mo yung bottleneck sa bass, does that mean the amp will distort earlier?
on stock kasi bass starts to attenuate at 100hz, since bass is attenuated you should be able to go louder tama ba? unlike yung tweaked version where in down to 30hz frequency response is flat that should add extra strain sa amp since its going to be producing more bass and so you wont go as loud?

I tested it bro. It depends on the limit of speakers. Example, Bose HVC hanggang 12 o'clock lang ako. pero malakas na yon. Beyond that my speakers will clip. Pero sa Audio Nirvana ko, kayang kaya, hanggang 2 o'clock kapag low quality iyong CD. Kaya nag attenuate siya bro, hindi na kayang ibigay ng DC power caps (stock) iyon hinihingi ng speaker mo. You can notice it if you play bass music. Kaya kapag naka hi value good quality capacitor with low ESR, safe siya. Anyway, nasa PSU mo naman nakasalalayang ang tripath chip mo. Hangga't di ka nag over sa required or ideal PSU as per tripath, walang masusunog na tripath chip. Di ba sir? Kapag ganito kataas na value gamit sa tripath 2024, parang solid state na din siya sa dynamics at limitation sa volume control which is 1 o'clock. But the SQ is beyond what I expected. Satisfaction guaranteed.;)
In addition to this, we should not be after on how loud it will play, but the quality of music it will bring. Kapag malakas na, wag ng ilakas pa at nakakaperwisyo na sa neybors. Baka sabihin lagi na lang may banda sa bahay niyo. ;D Parang ako, nagpatugtog lang ng Pearl Jam..maya maya bumili ako ng softdrinks. Ang sabi sa akin ng isang tambay, sir ayos iyong practice niyo...kayo ba kumakanta? ;D. Natawa na lang ako.

bigger caps mean bigger room the cap will never run out of steam.. But for the loudness i really cant say its not the caps its more on the gain side "resistors".. First do the cap upgrade also the PSU 12v 3A is perfectly fine.. Panasonics are fairly small will fit in paralell with the board..

yup depende sa PSU, i've tried the sure TK2050 board with the PS of yung Dayton DTA-100a, maayos naman ang bass, sasabay sa solid state. :)
-
err, don't get me wrong po pero malaking factor is yung speaker mismo sa bass kasi sa dta-1 palang busog na sa bass yung Titus BS ko..just my 2 cent. ;)
kung dati ng kapos ang bass ng speaker mo wag mo na asa sa amp. :)

Tama, different drivers (woofer, midbass driver) has a different sound or bass characteristic, so pag mahina mag bass o di maganda mag bass, wag na iasa sa amplification instead sumubok ng iba hanggang mahanap mo yung gusto mong sound characteristics.
-
^hindi naman ako nakulagan........swak lang.....dpended yan sa psu mo, kailangan me ibubuga yung psu mo during transients.....
+1...true indeed as per my observation. ;)

Proper matching is very important in choosing the right amp. We must also be aware of the freq.response of the speakers itself. If we see the speaker freq.response is 30hz (lowest bass it can produce in the speaker cabinet) - 18khz...means it has good bass. If the wattage and sensitivity of your speakers and a simple room acoustics (like having thick curtain and carpet flooring, proper positioning of speakers and vice versa) can help us achieve good performance from our audio system. Actually SOP na yan kapag nasa audio hobby ka. Kaya nga ako may XLO Test and Burn CD to know if I am hearing right. :)
Pansinin mo kahit computer speaker lang sa office na properly design, ang ganda ng tunong kasi kulob. Pero subukan mo ilagay sa untreated room and nipis tumunog. Though, meron din talgang magagandang speakers na mganda na din kahit di pa acoustically treated room. Bonus na lang iyong treated room to have better listening session. :)

How does Dayton DTA 1 sounds like when upgraded with 10,000uf Panasonic capacitor and paired with Apple I pod shuffle only???
Here is the You Tube Link: http://www.youtube.com/watch?v=EfKyYVTaLsA (http://www.youtube.com/watch?v=EfKyYVTaLsA)
Warning: If you use 10,000uf Capacitor for the DC Power of tripath, do not exceed 12 o'clock if the recording is in good quality. Exceeding from the said limit will clip the speakers esp.if 25 watts. (watch the video and listen when my Bose HVC clips). That is why I adjust it to 12 o'clock max.from previous setting which was 1 o'clock. Increasing the DC Power cap value gives better details, and soundstage and also increase the output/gain.
Thanks for watching. ;)

Hi-fi technology turns to smaller, cheaper chip-based operation
1/3/2006 8:01:00 AM
Source : Business World
DAVAO CITY -- Within five years, the high-fidelity audio industry would be shifting to smaller, lighter, and inexpensive electronics, specifically in the case of stereo and multi-channel amplifiers.
Electronic chips developed in recent years that are capable of producing audiophile-grade sound would eventually put aside high-priced amplifiers into vintage category.
This breakthrough has taken root among electronic do-it-yourself enthusiasts and, in a couple of years, would likely be applied in consumer electronics produced locally.
Since early last year, audiophiles have tested and modified their sonic impact tripath amplifiers, the first commercially available audiophile-grade chip-based hi-fi gear brought in mostly through online sources.
The first generation sonic impact T-amp is small, weighs just a few grams without the batteries, with cheap plastic casing and sold for as low as $20 from e-cost, a United States online retail site.
My two units, which arrived in Davao sometime in April, were bought through Amazon.com and cost an average of P2,500 apiece including forwarding charges.
A good number of Manila-based audio enthusiasts, however, got their units earlier, with the majority applying modifications such as changing the capacitors, improving the connectors, and installing a new potentiometer, or volume control knob in layman’s terms.
Many went for better-looking amplifier housing -- handsomely sculpted wood or transparent glass -- which do not result in sonic improvement but certainly attracts both enthusiasts and non-enthusiasts alike.
The sonic impact T-amp is rated at an average output of eight watts per channel at eight ohms, or 15 watts per channel at four ohms, an output at par with many tube amplifiers.
That rating is adequate for normal use and could even meet the demands of dynamic chamber music at loud volume in a typical room of, say, 20 square meters, provided efficient speakers are used.
Efficient reproducers mean those rated at 90 decibels at one meter listening distance and at one-watt amplifier output.
Since the amplifier’s usual electronic components are shrunk into a small chip -- the Tripath TA2024 -- less than one square inch in size, heat sinks are no longer needed.
Efficiency also improves with the signal travelling a shorter path compared with traditional amplifiers. With low output and a new amplifier topology, power is optimized translated to lower consumption without sacrificing sonic quality.
The T-amp needs a separate power supply, though, since it was originally aimed at the mobile audio market.
It operates using eight penlight batteries, which could last several hours of continuous playing depending on preferred loudness level.
Without the batteries, it needs a regulated 12-volt power supply converter to be plugged into the standard 240-volt power line.
The converter rating should preferably be at three amperes to maximize the amplifier’s rated output.
Such preference is derived using the general formula of voltage multiplied by amperage is equal to output in watts, in this case 36 watts or slightly over the 30 watts total maximum output of the unit.
Initially, local audiophiles claimed it is best to hook the T-amp to a 12-volt lead acid battery to perform best, but in my experience, using a 12-volt regulated converter does not result in sonic degradation.
This is confirmed by latest observation among foreign audiophiles as per posts in audio discussion fora. Since I have two units, one has a regulated 12-volt supply and the other a 13.6-volt converter, which some listeners in the US said results in better low frequency response.
On the first day I received my two T-amps, I tested one unit against a 30-kilogram (240 watts per channel at 4 ohms) Sansui AU-XII amplifier, originally priced at ¥275,000 in 1983.
I arranged them to appear as if I was comparing the Sansui with another amplifier, an Accuphase E-302 (180 watts per channel at four ohms) using similar sounding speakers: ElectroVoice Interface A and Denon SC-104.
My two children who came in from school had common observation: there was no difference at all when the volume of the two units were at room level.
Increasing the volume several notches higher, the children said the Sansui was slightly better sounding, not knowing it was actually a small 15-watt T-class amplifier not the Accuphase, which was compared side by side with the Sansui.
My wife who came in later said even at high volume, the sound quality from the two amplifiers was the same. Later, they were surprised to find the one pitted against the Sansui was a small amplifier that looks more like a child’s toy.
In the succeeding days, friends who would visit me were also amazed by the T-amp’s performance considering they were used to hearing only monster amplifiers.
In my opinion, the sonic impact T-amp’s sound is significantly superior compared with entry- to mid-level amplifiers, whether new production or vintage types.
Its sonic character could be described as in between the solid state’s fast, clinical response and the tube’s sweet and gradual sonic decay.
While it puts out clean and pleasing sound, the drawback is in reproducing the dynamics required by some classical and show-off pieces at loud volume.
A listener into rock, jazz or the usual popular music categories would be happy with this amplifier, especially when hooked to mega-loud performers from Klipsch, Altec Lansing, JBL, ElectroVoice, or Cerwin Vega.
By this year, higher-powered amplifiers using newer Tripath chips would likely achieve what the monster vintage amplifiers -- those with continuous outputs of at least 200 watts per channel -- could do.
The Tripath chip’s ascent as an audiophile-grade amplifier component started last year when a San Diego, California-firm sonic impact technologies marketed its Tripath-driven amplifiers aimed at the mp3 player market, specifically users of Apple iPods.
Some early buyers accidentally hooked their small plastic toys to larger speakers and the rest is sheer serendipity.
Last January, TNT Audio , Europe’s leading audiophile Website, reviewed sonic impact T-amp and found its performance comparable with solid state and tube-based amplifiers costing thousands of dollars. That review resulted in a sudden demand surge causing a temporary supply shortage.
Hundreds of local audio enthusiasts were among the first wave of T-amp buyers early last year with some enterprising groups accepting advanced orders in Manila at P3,500 per unit.
A few realized they could buy cheaper and went straight to online distributors.
That costs less than P2,500 per unit, coursed through a local forwarder, with delivery time from one to two weeks.
Acquiring the original sonic impact T-amp at less than $30 nowadays, however, could be difficult after the company introduced recently a revised version of the original amplifier now priced at $139 P7,367 at $1:P53) per unit.
Except for a better-looking case and improved connectors, all other specifications of the new model are the same as the old unit.
Dr. Adya Tripathi, the Indo-American engineer behind the Tripath chips noted as far back as 2003 that chip-based amplifier technology would dominate the consumer electronics subsector before the end of this decade.
Mr. Tripathi’s company, Tripath Technologies, Inc. based in San Jose, California, started operating in the mid-1990s.
The latest feedback indicates the price of Tripath chips has fallen from over $10 (P530) each for a low-powered amp a couple of years back, to less than $5 (P265) each now for high-powered amps.
The latest of the company’s amplifier chips puts out 400 watts output and designed primarily for subwoofer application.

Baka mapabili na rin ako ng T-amp. Ang daming puwedeng pagkunan sa Taobao ;D
magpasok ka ng ibang putahe para marami pagpilian. yun pang diyr at yung ready na pero pwede modify/tweak upgrade.
these chip amps are alternative source of affordable quality sound that rivals more expensive gears yet does not consume that much power (electricity).

Ang ganda tumunog ng Topping TP10 mark iv (TA2024) na pinares sa 4in 97dB full range BS. Panalo.

Hi. I stopped the hobby a few years ago. I recently got the audio bug and came up with this setup. My source is a MacBook Air 11.6" with Amarra 2.2 player, Indeed Hi-Fi Lab TA-2024 amp, Mirage Prestige S8 sub, Fostex FE167E single drivers speakers in bookshelf boxes. Good to see fellow t-amp enthusiasts.

May topping TP10 MK4 ako ganda tlga tumunog! Very high ung parts na ginamit alps, dale resistors, evox caps, elna, nichicon.. All in! ;D I upgraded the power caps ang stock kasi 2x 230uF 35v, ang nilagay ko Panasonic FC 2x 2200uF 25v.. Lalong gumanda! :D wala lng available na mundorf 2.2uF palitan ko din..

Maganda tlaga TP10 MK4. Actually bago namin sya nabili ni sir rascal ang dami nakapila na iba't ibang T amps
Hinahatak lang ung connections sa likod then plug naman sa kabilang unit. nde naman kmi nahirapan mamili dahil iba talaga ang SQ ng TA2024 ;D
Then we proceed sa ibang shop to look for a speaker. Nakita namin ung 4" na full range nka hooked sa 300B SET nagandahan agad si sir rascal according sa owner ng shop 97dB daw :) then we ask na i set-up ung TP10
Napa-iling nlng ung may ari ng shop parang ung 300B pa rin ung tumutunog...
Napabili tuloy ng speaker si sir rascal ;D

Better ba SQ ng usb input ng t-amp vs headphone out to t-amp ng MacBook Air ko? Mataba na kasi tumunog ngayon eh. I haven't tried outboard dac.
-
For a very good HIFI output:
Laptop -> USB to SPDIF Converter (like M2Tech's HIface) -> Outboard DAC -> T-amp
OR
Laptop -> USB to SPDIF Converter (like M2Tech's HIface) -> Outboard DAC -> Tube Buffer (optional) -> T-amp -> Speakers
Better ba SQ ng usb input ng t-amp vs headphone out to t-amp ng MacBook Air ko? Mataba na kasi tumunog ngayon eh. I haven't tried outboard dac.

How about the t-amps with usb inputs posted above?

If the usb sound chip is properly implemented and that jitter is minimized at a very low level then I believe it can sound good.

-
How about the t-amps with usb inputs posted above?
Even if it wasn't that good, I bet it'd still be cleaner-sounding than the MacBook Air's headphone out (unless the product is that bad). Imho, Macs have fairly decent amplification on the onboard sound when compared to low cost pc notebooks and netbooks (even if they use the same chips for audio). However, they're still more prone to noise from the other components and the power supply, when compared to external sound devices (including very simple ones like these).

Now, here's the deal: If I blindfolded you and had you listen to the amps in my collection right now -- the Almarro EL84 SEP stereo integrated with its punchy pace & rhythm and slightly dark & warm but naturally detailed soundstage; the emotive and musical Fi 2A3 SET monoblocks with their open, relaxed, dynamic and detailed sound; and the Yamamoto 45 SET stereo amplifier with its clean, clear, spacious, über-detailed and artfully musical sound -- and if after that, I slipped the T-amp into the mix and asked you to comment on its sound... what do you think you'd say? I guess it'd be close to what Bill said: "Its sonic signature reminds me most of the Yamamoto 45. It is clean-sounding with lots of detail and decent rhythm and pace. Not quite as smooth and musical but very good." When I told Bill and Pete that the T-amp cost a mere $39, they were flabbergasted. After I placed the T-amp into Bill's hands so he could "look" at it, he burst out in a marvelous laughter over its combination of light weight, small size and heavyweight performance.
...The Almarro, Fi and Yamamoto all play music wonderfully well, sound terrific and are relatively expensive. The Fi costs almost 100 x what you can buy a T-amp for over the Internet. Yet the little T-amp is not put to shame by any of them in its sound quality and ability to play music. I almost hesitate to confess that because I predict that some people will find it hard to swallow. But that's the way it is.

T-amps really sounds hi-end, I have an almarro clone before, with 6c33c-b tubes , silver-gold in oil mundorf caps, ecc88 siemens gold pin and almost all electrolytic caps are bypassed by mundorf mcap. very good amplifier, and I bet it will kick any amp with a 300b tube (not all), but funny how it seems, I settled on a t-amp, dont get me wrong, my SET amp really sounds good,(and it really kicks ass!) but the only difference it has over the T-amp is the warmth and a bit of dynamics. so I thought, why not buy a good T-amp and make it better? And thats what I did! and the result? oooooooooh yeah! but offcourse theres the t-bug that bit me (TBAG-temple bantam) another upgrade I guess.... hehehehe!!! ;D

I must admit T amps are really really good! Specially the 2024..

Adya Tripathi's corporation goes bankrupt. Cirrus Logic acquires its assets and Tripath amps go from strength to strength.
This returns us full circle. D-class, in certain implementations, has achieved surprising maturity. Tube lovers exposed to them agree how these amps bridge the old polarization of transistors and tubes. That neither means all class D amps sound the same nor that some of them sound 'like' tubes. What it does mean is that they can offer many of the good qualities of tubes together with core aspects of transistors. For the experimenters among us, it's fortunate that the market now offers quite the choice of low-power amps and the necessary speakers to go with them. It makes audio polygamy financially feasible for more of us. Thus spaketh Harem Baba...

This is my video of Dayton DTA 100a which I got from Ivan (a.k.a Kemozavi) last Saturday August 13, 2011. After an all day break in period estimated 8hours. In other words, not yet fully broken in up to this date I posted the You Tube video.
I only upgraded the DC Power Cap with Evox Rifa PEH 169 2200uf. I chose this cap for its sweet detailed character.
Here is the You Tube Video link:http://www.youtube.com/watch?v=YgsyO8h2aPg (http://www.youtube.com/watch?v=YgsyO8h2aPg)
I am hoping the SQ will improve better as I continue the breaking in period. So far, I agree with Carl (a.k.a Xtian_lugz) why he loves Dayton DTA 100a. Also, will try Topping TP22 in the future. ;)

+1M. If only people will always use their ears in audio and concentrate on the music played or rather, how it was really played in recording studio or live recording, they will love the Tripath Amp. You will just modify a little and there you go, enjoying music with gusto without worrying monthly electric bill expenses. I played back various Pearl Jam albums and I can hear details and differences of each album recordings. Either you use mp3, laptop, cdp, USB Turntable, and cellphones, tripath amp will bring the musical performers in front of you.
If you are short of budget or have a lovely wife who hates spending on audio, tripath amp is the answer and D.I.Y. As for me, I am contented with DC Power Cap upgrade and Mel's (a.k.a rascal101 who is starting to save lots of money in abroad) tweaks such as Choke, resistors, will have a very good SQ. You can hear that some artists have some flaws on performing their music. It is an advantage for us listeners, if we listen to music deeply. :)

Agree all the way with Sidny... details and transparency are what I am after with tripath amp. I compared it side by side with Tube and other HI End SS, the details are really great. Yes, the tripath has its weaknesses. But doing some upgrades and modifications will make tripath amp a total performer for all types of music. If you love details and transparency ...this is the amp for you.

happens lot's of time.......it is usually the end users who get the most excited and euphoria builds up.....it takes time for reality to sink in and when it does, you see those gears in the for sale section......oh well, that is how the cookie crumbles.....memory, specially audio memory is very fleeting.....
sabi nga ni Erap, "wether wether lang yan...." ;D ;D ;D
while the designers would say, "it's all in a day's work...." their reason for existance is to come up with products that will sell.....
lest somebody get me wrong.....the T-amps are good sounding amps and very high efficiency, what's not to like? ;D ;D ;D

We are going to have vacation on December there. My wife is working in Citibank. I can bring mine and have some listening. We can also go to Edwin's place there to share tripath power at his place, if he is available. Because he is an SS and Tube type guy. You can PM him so that you can meet. His handle in PDVD is "Edwin"
Ingatz bro.

will bi-amping using two different t-amps work?
It's not applicable to fullrange or pointsource driver or single driver. But it is possible for 2 way speakers. Other D.I.Y used Tripath 2024 for the Hfreq. and Tripath TK2050 for the low frequency. You must have a separate Pre amp. :)

one time i went to Malabon with Edrel, this guy RV(not a member of this forum) showed us his 5 way system, he's into multi-amp, multi speaker set-up, he uses a Rane 5-way electronics cross-over and had an amp with T-amps, i believe they wer Lepai's, 5 stereo amps in a single chassis, Aikido line amps using 7193/2C26 horny tubes........they drive the low mids, high mids, tweeters using horns......
-

sir tony wont the passive crossover of the speaker suffice?

thanks, is the purpose of the pre amp is to regulate the volume? can i just adjust it using the two amps?
pre-amp====>electronic cross-over=====>power amps

sir tony wont the passive crossover of the speaker suffice?
no, this is a completely different ball game now....you will not need passive cross-overs.....

This is my video of Dayton DTA 100a which I got from Ivan (a.k.a Kemozavi) last Saturday August 13, 2011. After an all day break in period estimated 8hours. In other words, not yet fully broken in up to this date I posted the You Tube video.
I only upgraded the DC Power Cap with Evox Rifa PEH 169 2200uf. I chose this cap for its sweet detailed character.
Here is the You Tube Video link:http://www.youtube.com/watch?v=YgsyO8h2aPg (http://www.youtube.com/watch?v=YgsyO8h2aPg)
I am hoping the SQ will improve better as I continue the breaking in period. So far, I agree with Carl (a.k.a Xtian_lugz) why he loves Dayton DTA 100a. Also, will try Topping TP22 in the future. ;)

I've always liked Lyngdorf and TacT for having robust fully digital designs. NAD's M2 direct digital amp is also a welcome addition to the group.
Sony (S-Master), Panasonic (XR models), Victor/JVC (RX-D models) and Sharp (1-Bit) have lower-cost direct digital implementations, afaik. I think most other major CE makers are jumping-in the bandwagon, because it makes sense design-wise (cost/performance can be improved, especially for lower cost envelope modules/products and smaller form factors). Sharp tried to make it in the higher end segment with some of their pricier 1-Bit Technology products, but they had to return downmarket.

ayan may adv. info na si sir monreq. yun kasi isang youtube link, smoke on the water pala. eh naka-konekta sa setup ko ito desktop, muntik mabulahaw kapitbahay.
ang sarap pakinggan ng hotel california live acoustic esp pag napanood mo na yung dvd. visualize mo yung lagitik ng gitara at bagsak ng drum sa umpisa, hinihimay mga instrumento. kaya isa sa reference ko ito pag mag audition.....’this could be heaven or this could be hell’...just like the audio hobby - You can checkout any time you like, But you can never leave!

Agree. It's not the power that counts, the reason why I love my tripath is the SQ. Meaning, I am not after for those high powered Tripath amps. As per experience, low wattage tripath amps produce better SQ and those in the wattage of 50watts is my maximum. Beyond that wattage, I am not sure if the SQ particularly details and soundstage will be like tube-SS combo characters. Sometimes, higher wattage on tripath is like having a good qualtiy SS amp but not as sweet, and detailed like tube amps. As much as possible, I want to stay close with the original design tripath Sonic Impact TA 2024 and TK2050 if you need good bass kick. Those two types of tripath chips are my favorites and for keeps with regards to SQ.

What T-amp would you guys recommend? Budget 10k++

tumpak! kaya ako ta2024 loyalist. excellent SQ esp mids and HF. heavenly matched with my speakers. yung bass, bahala na si subwoofer ;D
yung ta2020 ok din kung hanap mo medyo makapal na lower mids, pero naapektuhan yung hf.
tk2050- ok din esp sa low freq, balanced presentation... tradeoffs.
___
What T-amp would you guys recommend? Budget 10k++
anong speakers ang gagamitin mo? ano hanap mo sa music? warmth, tight bass? o crystal clear mids, very detailed highs etc?
-
tk2050- ok din esp sa low freq, balanced presentation... tradeoffs.
I experimented the DTA 100a. By using a very good quality DC power cap like Evox Rifa PEH 169 2200uf 63v, the overall frequencies improved as in details were all there and an outstanding mid and low freq. Di nakakahiyang itapat sa mamahaling tube amp ang SQ basta iyong DC Power cap na iyon ang gamit. I am not sure with other DC Power Cap. Kasi iyon Panasonic hindi ganun ang effect at iyong ELNA na ginamit ko sa experiment. What I know is that low ESR is very good character of DC Power cap.
Some ref.about ESR: http://wiki.xtronics.com/index.php/Capacitors_and_ESR (http://wiki.xtronics.com/index.php/Capacitors_and_ESR)
So, if you want to buy one, you must look for the lowest ESR possible. Don't just look for the brand. Some cheaper capacitor have low ESR too. Though, most LOW ESR caps are good quality capacitors.
-
What T-amp would you guys recommend? Budget 10k++
To be sure that your speakers will kick bass, you must use tripath amp with TK2050 chip. Upgrade the DC Power cap with a low ESR 2200uf value.
Here are the list of LOW ESR Capacitor Manufacturers that is available in the market: click link:http://www.capacitorlab.com/low-esr-capacitor-manufacturers/ (http://www.capacitorlab.com/low-esr-capacitor-manufacturers/)

sir napansin ko fs sa marketplace yung ta2020 t-amp mo. i guess if you are upgrading and want a more powerful tripath chip based amp, its the tk2050. ok yun Sure tk2050 ni sir ivan.
pero kung hindi issue sa iyo ang power (pag may 93db+ speakers ka at hanap excellent mids & hf, you may wanna try the ta2024. pwede mo ipa-modify upgrade kay sir monreq.
try mo din virtue audio- model One or Two. you can pm sir romymartinez

gumagamit ba kayo ng preamp kapartner ng t-amps niyo?

I dont have the technical know-how para bumuo ng sariling T-amp. I think pang DIY'ers ang Sure Tk2050 although I could be dead wrong. The TA2024 is also in one of my choices kaso wala akong alam na nagbebenta ng ready made amp with this implementation. I also dont have a sensitive speaks kaya issue nga ang power para sakin.
BTW thanks sa mga rinefer mong peeps sir. I will research muna pa para makapag PM na ko sa kanila :) thanks.
-
Hindi ako gumagamit ng preamp with my 2024. I run straight mula sa headphone amp ng MacBook Air 11.6". It sounds really good now. Pero curious din ako sa tunog kung dumaan sa magandang dac at tube buffer.

Psst! Di ako tech guy to upgrade others... hobbyist lang ako. Kaya naman nila yan kahit di na ako ang gumawa basta marunong lang sila maghinang. :)

Hako din hindi hako gumagamit ng pre amp or external DAC. Kasi may DAC na ang Sony CDP 950 ko. In my observation mas raw at makapal tumunog kapag rekta sa source ang tripath. Iyong details makukuha na yan kapag nag upgrade ng magandang klaseng DC Power cap. :)

Help po for a newbie.
I'm planning to get a Sure TK2050
This one:
http://www.ebay.com/itm/2-X-100Watt-Class-D-Audio-Amplifier-Case-TK2050-/120771627729?pt=LH_DefaultDomain_0&hash=item1c1e8ccad1 (http://www.ebay.com/itm/2-X-100Watt-Class-D-Audio-Amplifier-Case-TK2050-/120771627729?pt=LH_DefaultDomain_0&hash=item1c1e8ccad1)
Pero wala pa kasamang power supply.
Enough na kaya yung mga laptop adaptor sa CDRKing?
May nakita ako 24v/4a max.
Is that enough?
Kung may ma-susuggest po kayo na mas ok na power supply, pa-suggest na din.
Clueless pa kasi ako.
I recently purchased a TA2020, pero medyo nabitin ako sa power. Hindi kaya i-drive yung lumang AKAI speakers dito sa bahay.
Thanks!
-
Okay lang kaya gumamit ako ng dalawang TA2020 based amps para i-power si wharfedale 10.1? Yung passive crossover nalang sa loob ng speaks ang gagamitin ko. Yung isang amp para sa tweeter, yung isa para sa woofers. Wala ko idea kasi kung ano kalalabasan ng tunog pag naka bi-amp.

Unless gusto mo adjust yung relative intensity nung drivers, baka mas ok one for left and one for right (vertical bi-amping).
-

If I do that, will i hear a volume increase if I compare a single amp with the volume knob @ 12 o'clock vs. a bi-amp setup with both amps @ 12 o'clock? Because sometimes, I find myself wanting more volume. The specs of the Wharfedale 10.1 aint exactly TA2020 friendly ;D
Also since my TA2020 amp indicates that it is 20wpc, if I put an amp for each channel, will that equate then to 40wpc?

Chances are, if you'd hear an increase in volume, it'd be very tiny. You're definitely better off getting a single TK2050 amp for the same money, if that is what you're after.
Also since my TA2020 amp indicates that it is 20wpc, if I put an amp for each channel, will that equate then to 40wpc?
No. That's not how this works, unfortunately. The only advantage of passive biamping is that you minimize driver interaction, and you get more current headroom in certain instances.
-
I see. So I guess the best chances of getting more volume, and the advantage of passive bi-amping is to get 2x TK2050.
Thanks sir Stagea. You've been really helpful. :)

having 2 ta2020 amps wouldnt render 40wpc unfortunately, the benefit of having 2 tamps though is you get better flexibility depending on how you wire them like a single amp driving LF and another amp driving HF signals, this setup lets you adjust the tone of the speakers... if you find the speakers a bit dark/warm sounding you can increase the volume of the t amp driving HF, same goes with bass, pag medyo mahina ang bass then increase the volume of the t amp driving LF signals...
you can also wire them one t amp per speaker,,, advantage of this setup is you get better headroom... on the case of the ta2020 amp, it is actually just producing 7wpc or 8wpc @8ohms clean and 12wpc @4ohms clean having a single t amp per speaker gives you more or less the actual rated output of the T AMP "clean"... oh and you also get better seperation on this setup...
another thing to consider though is both of this setups would require that you have some sort of a preamp because everytime you need to change volumes,, you would have to change volumes of both tamps... so in the end your kinda spending more. ;)

Yeah I kinda get the idea now. My pre-amp would only be a measly USB sound card since this is a PC based setup for my room ;D. I found a way to have 2x stereo outputs with proper configurations to the software, so immediately, bi-amping came to my mind.

hehe, goodluck on your project sir. :)
-
there are sound cards that have this 5.1 ouput jacks....you can get 4 lower power t-amps for the fronts and rear... and one big t-amp for the woofer and you will have a good pc based system if you don't mind using your pc as your source....

HELP!
my SA-36A t-amp will have this clipping sound at 9 - 10 o'clock.
this is paired to FR FS and sometimes to JBL FS heritage series.

May problem yung sonic impact t-amp ko. Yung left speaker niya parang not enough yung power. If I play music na sobrang hina ok siya, pero kung regular sound level nagcracrack yung sound sa left. Do you guys think I could get it fixed or should I just change it?
-
I've been reading some of the pages here and it seems parang DIY itong mga t-amp.
Meron bang nabibili na buo na good for stereo, cdp, pc listening? I've scouted ebay but i'm not sure what brands are ok and if they are already assembled completely.
Hope someone will enlighten. Thanks!

That's being sold by Capital 1. i didn't check out everything but the picture showed that it was the Muse DT50A. I haven't tried using T-amps as i only have an onkyo 609 for HT and a JDLabs integrated amp for stereo listening. Try contacting capital 1 or kemozavi for audtions, pretty sure they'll be happy to help you out.

Magkaiba yong dayton APA-150 at Muse DT-50a. The APA-150 is an integrated amp CLASS AB without using any tripath. The MUSE DT-50a is base on tripath. It has the tube sounding, fast and more detailed sound. I could not say both have 75 wpc. I tried using both amp but with my FR alnico I prefer the MUSE DT-50a. ;D
-
thanks soundgarden...Now i know the difference.

thanks soundgarden...Now i know the difference.
Brader to simplify my review on MUSE DT-50a it's a combination of Topping TP22 and TP60 or APA-150 = Muse DT-50a ;D

Galing talaga mag compute ni bro. Jorge. ;D Nakuha mo pa yon? Kidding aside Muse DT50A is a good tripath amp that can rival European and U.S. branded tripath amps.

preamp left chanel out + yjack to tamp left & right input \ tapos yung L speaker out to L speaker woofer, R speaker out to L speaker tweeter
tpos ganun din set up sa right channel,
may improvement kaya??

Vertical biamping po tawag diyan. It can give you less crosstalk between the L and R channels, reduce interaction between your LF and HF drivers, and deliver greater current capacity per side.
In most cases, buying a better amp would yield a greater improvement though (versus spending money on passive biamping two lesser amps).

Wala pa ata locally. Mukhang interesting yung products nila, especially at this price point. Yung mga ready to use amps (G300V100, G300X, G200N and G33D) presyong transformerless amp module lang ng iba running the same chipset. The build looks nice for the price naman, saka backed by a 2-year warranty.
Their amp modules are also reasonably priced. Pwedeng pangbuo ng affordable power amp. :)

finally i got the 999 peso amp kit from Elab up and running:
http://www.electronicslab.ph/forum/index.php?topic=30065.0

i used an 18-0-18 volt transformer, dropped 6volts at full blast:
(http://i5.photobucket.com/albums/y155/leoman53/classD/ClassD_1359.jpg)
initial impressions, this amp is so cool to touch that i suspect i can still up the input voltage to up the dc rails for more power.....will wind a new power traffo with bigger capacity and investigate....
soundwise, very clear, no sibilance, bass is ample, no need for a subwoofer.....

i'm new to this hobby. i just want to know if the topping tp30 will be enough to power my yamaha speakers: nominal input 70w
music input power 250w
nominal impedance 6 ohms
sensitivity 90 db/w/m
3 way 4 speakers.
i've been thinking of getting a t amp for quite some time now since my luxman m02 is giving me static while it's playing. i don't know if i should get a t amp or i should just have my luxman repaired. i don't know where i can have my luxman fixed btw. is it also fine to put a preamp before the topping tp30. my luxman c02 is still working fine.

Guys, can you recommend a pair of bookshelf speakers at least 94db efficent to be driven by a 20wpc t-amp?
Alternatively, can you recommend a diy speaker builder for a single driver FR at least 94db efficient (Alnico, Fostex, etc) using double bass-reflex type enclosure in real wood veneer cabinet? TIA.

How does dayton compare with topping in terms of sound and build quality?

How does dayton compare with topping in terms of sound and build quality?
Depende sa tripath chip. Kapag Dayton DTA 100a vs. Topping TP22 wherein both use TK2050, sa DTA 100a ako kung hanap ko dynamics, slam. Topping TP22 on the other hand is ideal for jazz, vocals due to its tamed bass. Akala lang kasi ng iba pare pareho tunog ng T Amp. Depende sa Tripath chip na gamit yan at kung panu design ng circuit. Mahirap kasi generalize na manipis ang bass or kulang so low frequency ang T Amp kung di pa naman nasubukan ibang tripath chip. Anway,ang problema lang sa Dayton DTA 100A, di siya kasing tibay ng Topping brand. Ang Topping kasi maganda ang protection circuit niya. Kapag nagkamali ka ng gamit sa amp like for example di mo alam clipping na pala o hirap na siya, ang topping mag automatic shut off. Ang Dayton DTA 100A mag shut off forever.
Kaya dapat pag nag tripath ka, wag ka lalayo masyado sa wattage na kaya niya. Kasi kapag nabitin ka sa bass ang gagawin mo ilalakas mo ang volume hanggang sa di mo namamalayan nag over heat na pala ang tripath chip mo. Based on experience yan bro.

Hi sir, meron po ako lepai ta2020 tripath amp na di ginagamit sa bahay., due to nakabili na ako ng 2.1 system.. also meron ako akg k240 studio, sa tingin ko nahihirapan sya idrive ng pc audio out or ng mp3 player ko. pwede ko kaya gawin headphone amp yung t-amp?

gurus, just want to asked some few question about the T-amps.
I have a pioneer VSX 521 AVR, and a set of wharf diamond 9.5 FS, 9cs and 9SR for 5.0 set up (no sub yet)
I haven't hooked the center and surrounds yet sicne I dont have the sub for it pa.
I'm mostly maximizing the stereo listening for the meantime.
now for my question and to cut the crap.
- are these T-amps possible to be connected to my AVR?
- I was planning to get one for my stereo listening sana.
or is the power of my pioneer vsx 521 already enough for the wharf 9.5?
- if I connect this to my AVR will the avr work as a pre amp and T-amps as main? will the wattage of the t-amps be added on top of the wattage of the pre-amp?
- and would there also be a big difference in terms of sound quality even without doing Bi-amping the wharfs?
I am now satisfied with how my set sounds, but I would like to discover if using a t-amp would squeeze some more juice to add some more sound quality to it.
sorry for the ignorance po about this things, hope someone could answer my queries and help me with this...
-
BTW, would this be the connection if ever?
Pioneeer VSX 521-----CD out---T-amp ---wharfedale diamond 9.5
l
CD player IN
by the malaki po ba ang difference using the coax or digital connection compare to the RCA?
if I will use coax or digital from CD player to the AVR pag nag out ba sya going to a T-amp same digital signal din po ba?
-
any inputs po mga masters
?
-
May pre outs po ba ang receiver ninyo?

im a newbie when it comes to audio setups, balak ko sana active speakers like swans for 10-12k. Pero with that budget naisip ko mag mini amp + wharfdale 10.1. I was looking at Dayton DTA-1. Kaya ba nun? and balak ko ikabit sa pc/phone.
Wharfs>Dayton DTA-1>pc/phone.
Or mas ok Dayton DTA-100a?
And what else is needed for the above setup to work? Thanks

Depende sa tripath chip. Kapag Dayton DTA 100a vs. Topping TP22 wherein both use TK2050, sa DTA 100a ako kung hanap ko dynamics, slam. Topping TP22 on the other hand is ideal for jazz, vocals due to its tamed bass. Akala lang kasi ng iba pare pareho tunog ng T Amp. Depende sa Tripath chip na gamit yan at kung panu design ng circuit. Mahirap kasi generalize na manipis ang bass or kulang so low frequency ang T Amp kung di pa naman nasubukan ibang tripath chip. Anway,ang problema lang sa Dayton DTA 100A, di siya kasing tibay ng Topping brand. Ang Topping kasi maganda ang protection circuit niya. Kapag nagkamali ka ng gamit sa amp like for example di mo alam clipping na pala o hirap na siya, ang topping mag automatic shut off. Ang Dayton DTA 100A mag shut off forever.
Kaya dapat pag nag tripath ka, wag ka lalayo masyado sa wattage na kaya niya. Kasi kapag nabitin ka sa bass ang gagawin mo ilalakas mo ang volume hanggang sa di mo namamalayan nag over heat na pala ang tripath chip mo. Based on experience yan bro.
kuya mon,
nawala cellphone ko... ganyan ganyan nangyari sa dayton100a ako. marerepair mo pa ba kaya? ilang months ko na di nagagamit mga speakers ko. mapapahiram mo pa ba sa akin yung sinasabi mo na amp? hehehe.

Question lang mga masters, is the dayton DTA-1 the only battery powered t-amp available here? I'm trying to set my bedroom system to be mobile, meaning 2.1 with the satellites and the t-amp able to leave with me for out of town trips...
I actually have a DTA-1 right now, borrowed from my cousin, but it's need of repair na... Its looking like the volume knob contacts need cleaning or replacement... Would you know where I can have it repaired?
Thanks in advance!

yes, but you have to get yourself an electronic cross-over network....since the t-amp and your pioneer have different gain structures, tuning your system can be a bit tricky.....

Mga masters hingi po sana ako ng opinions ninyo regarding Motorola DCP501 Audio Video Receiver
I would like to know kung Tripath nga ba ang amp section nito and if the price is worth it?
Nakita ko lang po sa SULIT.

First-off it says it's Tripath. Analog nga lang and lumang modelo. But I'm after the amps section as I'm planning of using HTPC and/or Android TV Box as A/V source paired to an LED 480p projector for my humble HT setup and some Audio listening na din on the side. I really can't find on the net any info that confirms it's a Tripath amp. . .

Mga masters, san ba nakakabili locally ng Audio grade capacitors? Planning to modify my Lepai 2020A+ Amp.
Sa nabasa ko (http://techtalk.parts-express.com/showthread.php?226235-Modding-the-Lepai-T2020A), capacitor brands are Panasonic & Nichicon.
Just in case wala locally nung mentioned brands, ano po alternative and where to buy?

bro get a more efficient speakers(higher db) or get a higher wattage amp(t-amp or anything else).86db lang kasi yung wharf and the lepai/sonic TA2020 is only 20wpc i think,kung gusto mo small footprint at power efficiency try class D. tutunog naman yan pero baka sobrang taas na ng volume.
-
sige po. I'll try looking for other speakers nalang. I really want to use the lepai t-amp. min of ilang dB for the speakers?
-

if you really wanna use the lepai t-amp, I suggest that you bring it to the store/seller then audition every speaker that you can afford using that t-amp,in that case you can actually hear how it really sounds, db is just a number to indicate how loud a speaker can be but most of the time we don't listen to music because of its loudness but because we like how it sound,in short, amp and speaker matching is also critical so you have to audition it. i used an 89db speaker before paired with TA2020 t-amp but not lepai its SMSL 10-11 oclock volume level is ok for me for easy listening.
-
the lepai amp is lp-2020a+

94db up is what you want for class T amps. That pretty much narrows it down to really old speakers or diy. There are efficient drivers from Visaton, Fostex, and Audio Nirvana. AN has a local vendor. See the ads section. Anthony Audio has high efficiency speakers too. These speakers don't come cheap.
-
that is why one owner of a 2A3 set told me, the sound of his T-amp is comparably good... ;)
and at 6k cost to build..... >:D

Klipsch also makes efficient and sensitive speakers.

may tweak ba sa SMSL 36a para mas maging alive ang tunog?
partner ko ng speaker:
@ 85db simple lang sya pero ok naman sa acoustic (small BS)
@ 88db medyo ok (big BS)
@ 89db ok naman. (FS)
dapat ba tlaga nas 95db ang partner sa mga T-amp or depende parin.
-
^yung mga T-amp na low power kailangan 95db just like a tube amp,
SMSL 36a is based on the TA-2020 chipset, a proven tried and tested chip,
i suspect marami nyan sa Raon, at 12 volts, power is very limited,
there are T-Amps, class D that are high powered, they can drive subs,
hindi sila masyadong mamimili ng speakers
a tube buffer or a tube line amp is a good tweak for that amp...

^^ agree as well
BUT if the computer you're using is connected to your audio system it will at least give you a hint of the dynamics of the sound, plus there are some guys in youtube who does a decent job in recording like this one:
http://www.youtube.com/watch?v=pdAe9PdwLV0 (http://www.youtube.com/watch?v=pdAe9PdwLV0)
just make sure you select 720p or higher quality ;)

Yes. Pero that's only half of the story. We also have to consider the ADC & mic used to record the music as well. Napakadaming klase ng recording mics used by studios for different purposes.
-
Hindi ba pwede gumamit ng decent headphone at kahit papaano maririnig mo naman yun dynamics at imagine ng nasa youtube, pero still iba parin yun nasa harap ka.
I do have a friend kahit day and night na yun SQ sa kanya parang same parin.
Siguro malaki lng expectation ko sa T-amp para drive ang isang maliit na BS w/ 85db. need talaga ng mataas na sensitivity...

Pwede headphones BUT it will help you better kapag naka-attach sa sound system mo esp if you have a decent outboard DAC, we all know most computers/laptop have soso DACs.
I used to own a Topping TP22 which uses the TK2050 tripath chip @ 22wpc, DIY Paradise Charlize 1 w/ TA2020 chip @ 10wpc & a friend lend me for a couple of months his Topping TP60 w/ TA2022 @50wpc. The best sounding for me is DIY Paradise Charlize, I didn't have speakers to properly match with it back then & I regret selling it.

I have B&O ASX125 @ mono or bridged mode and as per specs gives 250Wpc @ 8Ohms and 500Wpc @ 4Ohms this is a T-amp right? Speaker sensitivity then is not an issue with mine and like it driving my Harbeths. So if your speakers are hard to drive just look for higher power chips, a lot in ebay and aliexpress, that's what I do and plan to make a 7ch ice power amp for HT.

quick question... I recently ordered a T-Amp online: http://www.amazon.com/gp/product/B008BW9K6E/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1, Stellar Labs 15Wx2 and did not see that there was no power adaptor included.
I tried checking Watts HiFi in MCS, and they didn't have any adapters available, and pointed me to WalterMart where I can pick up any universal power adapter daw... Will there be any problems with the output if yung universal adapter nga ang gagamitin?
I ask because I could still just order a matching adapter online (partsexpress) if it would still be a better choice... thanks!
not so OT: seems interest in the TAmps has finally faded... hehe
-
Orderin mo na lang yung matching power supply adapter para di ka nangangamba.
-
What chip is used in the Stellar Labs?
The thing with tripath chips is that their supply ratings are typically about 12V-13.2V and comes with a maximum Vs of 14.5V.
Those regulated power supplies sold in hardware stores and in Raon are set to output a standard 13.8V. Technically, this already exceeds the typical 13.2V but since you are still within 14.5V then you may or sometimes may not get away with it.
Those unregulated power supplies, also sold in hardware stores and in Raon can have a no-load voltage output of 16V, not a very good proposition but still, some gets away with using these.
Some will argue with this, I won't. But what I said above is a reality and breaching this settings is almost always the cause for premature failure of these little amps. What you need is either get a linear or smps power supply that has a no-load output voltage of 12V to be within the safe operating area of the chip. There are 12V smps supplies in sulit that you can adjust to exactly get 12V, all you need is a DC plug with wire and an AC main plug. This may be daunting for inexperienced tweakers so I think your option to order a decent 12V wallwart is a much wiser thought.
Cheers
-
thanks for the replies! further research shows that it is using a TA2024B chip... so I guess I'll go ahead and order a PX wallwart, per master JojoD...

another thing, will this have enough space for a Binding Post mod? and meron pa bang gumagawa nito? haha... muchos gracias and happy new year!!!
-
That chip has an absolute maximum rating of 16V, however, operating conditions states a maximum of 13.2V sir so ordering the proper psu would be your first wise decision for 2014. :)
OR, if you are the guy with idle hands then you may also use a pc psu, just wire the green wire to any ground and get the 12V and feed that to your t-amp.
A worthy cheap mod would be to slap one of these to the chip... they're available in most cdr king outlets.

sir ton, mag 2 years na pala tong amp ko :)
one of my better audio investments, iirc.
spoiled yung tenga ko sa 2A3 + altec fullrangers so i didn't really have high hopes with this amp's performance when i requested sir tony to build this amp.
plan ko lang sana was to use this for casual listening/back-up amp.
but i was really surprised at the potential of this amp when i tried it in my system. none of the harshness/forwardness usually associated with ss amps.
not as sweet sounding as the 2A3 but eerily similar.
no regrets ako for this amp.

plan ko lang sana was to use this for casual listening/back-up amp.
but i was really surprised at the potential of this amp when i tried it in my system. none of the harshness/forwardness usually associated with ss amps.
not as sweet sounding as the 2A3 but eerily similar.
no regrets ako for this amp.
i have another kit for assembly....TDA8920 chipset...http://www.nxp.com/documents/data_sheet/TDA8920B.pdf
although datasheet says 100watts per channel, i will not run this amp at full tilt, 75watt per channel is realistic for long term reliability....

Buhayin ko lang tong thread. Just got my tp60. Amazing amp for the price.really pushed the performance of my zigma hornets. Bass is deep and extends more compared to the sa36.will burn in for several days and check for changes..
May mga gumagamit pa po ba ng t amps sa pdvd members?

My Bang & Olufsen uses the ICE Amp. Its their version of the T-Amp or D-Amp.
Pretty good sound for the Bedroom, deep bass and nice highs...great for waking up music :D

what speakers are they driving sir?

I am a frequent traveler and I am looking for a stereo mini hifi amplifier...something light and handy which I can easily grab when traveling from one place to another. I've been looking for Lepai LP-2020A but I couldn't find a local seller. Is there other locally available good alternatives? Thanks.

saan nyo yan sir nabili? walang service center dito niyan pero any qualified electronics tech kaya yan, walang lang masunog yung mga SMT IC's madali namang maayos yan.

^if you can find the replacement parts and good luck with that....
accidents do happen, so it is always a prudent practice to turn off power when touching your set-up...
tuition cost for learning can be expensive at times....been there, done that.....i know now what not to do and when to do it...
-
Yeah.. my almost 8k down the drain.. unit was turned off.. my bad is that i didn't remove it from the AC plug.. the speaker wires touched the metal frame in my office cubicle... it sparked then smelled burnt electricity... my office pc was also affected since it is plugged via usb.. mother board said goodbye

I know t amps are different from class d amps but i don’t want to open a new thread so i’ll just post it here.😊 Any pdvd users tried the new amps from fosi audio, aiyima, topping and smsl? Are they any good as what some online reviewers say?

it is so small that it is easy to store.. that is where my t amps is.. in the storage… am not an audiophile but the sound of such as the rega amp differs largely from t amps but if you have maybe a good dac and a good full range speakers you can place it in tight places like small rooms and you can play with it using your phone as source.. maybe spotify, apple music or even tidal/qobuz

it's a class D no matter what they say, the TP3116 is a good amp...i made two of them and the owners are happy..

Got the Topping MX3 for its feature set. Good sound for the price, perfect alternative to a sound bar when mated to good bookshelves. Issue: did not last a year.

i have a Fosi Audio T20 (with tubes) pansin ko malakas sya vs Lepai LP 2020A+. pero soundwise mas prefer ko Lepai kasi sa pandinig ko mas maganda mids n highs.,,, Fosi Audio kasi medyo ipit midrange and to some extent treble. but the most bang for buck i bought lately is yung Tripath 2024 amp module from Shoppee 334pesos lang ! (meron din yata sa Lazada pero mas mahal).... i partnered it with an FX tube 03 tube preamp (bought 1.5k pesos 2 years ago) and driving vintage coral holey basket speakers in a 40 liter bass reflex baffles... my music source is a laptop connected to SMSL M8 DAC.... i was surprised it sounds so smooth parang tube sound ...lutang ang mids/highs with the bass authority of a solid state amp!....the coral holey baskets have a wonderful sound spread ang lawak ng soundstage... nowadays one can have a wonderful sounding sound system from cheap chopsuey parts, just experiment for a good mix and match :-)

I'm contemplating to buy a Fosi Audio V3 (TPA 3255 Class D power amp). It was given very good reviews at Youtube. Accordingly, made in Japan and Germany ang mga laman loob nito. Any body using it now?
