sir dito na ako ngayon sa singapore nagwowork. pag nakauwi ako dalhin ko tong amp.

mabuhay ang tripath!

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?

[monreq]

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.

thanks, is the purpose of the pre amp is to regulate the volume?  can i just adjust it using the two amps?

yes, you need an electronics cross-over though.........

 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?

pre-amp====>electronic cross-over=====>power amps

no, this is a completely different ball game now....you will not need passive cross-overs.....

ohh okay sir thanks, btw sir musta ung project natin?

on-going.......

excited e  im sure paired with my FiiO A1 t-amp it will open up a new world of listening experience

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

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.

Ganda parang nasa harap mo yung kumakanta

Pwede po parequest ng hotel california live

Thanks

that was also one of my options from diyaudio. ultimately I just based by decision by the lenghty forum discussion/feedback with hifidiyme.

Arjen boards are also of top notch build

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.

Ito iyung MKIII TA2024 nung manufacturer ...



Ito iyung pangalawa kong nakitang T-amp na iyung TA2024 IC ay naka heatsink.

Sir Gutchy 

audiophiler red caps ata ginamit (available at eleshop ronquillo), room for improvement kung gusto palitan.

nilagyan ko ng ram heat sink (cdr-king) ang ta2024 chip, sakto!

I am  not an Eagles fan but I will look for an original cd eagles live for you. Lalakasan ko na volume para mas malupit.  9 o'clock lang kasi.

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!

enjoy!

The T amp is now a "smoke on the water" and it's going "highway star" in Hotel California. Go..go..My idols in T amp here in pinoydvd.

keep on truckin'!

kayo na ang mga idols ko. happy na ako sa "VINTAGE" t-amp da orig. toy that started it all 

hype? fad? ...only time will tell. pero afaic, "t-amp"s, like... rocknroll will never die 

its only t-amp, but i like it, like it, like it yeah 

[ATJr.]

nice development over at elab.ph, there is an on-going design for a class D amp:

a serious attempt by pinoy techies to design and build one.......

[squatt3r]

ayus! my recent venture into this semi diy t-amp module re-awakened my interest with electronic stuff.

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.

[armymanhaha]

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 

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?

[monreq]

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

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.

[monreq]

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.
