I bought a silver unit and it now happily sings with a pair of n.o.s. Coral 10 inches full range in open baffle set-up augmented with twin active servo subs... hearing the reflected and delayed backwave sound has a very nice psychoacoustic effect...
enjoy ako sa ganitong set up , di na kelangan masyado malaking watts sa amplifier kung mataas naman sensitivity ng speakers....malakas na din..... thanks RXV for the miniwatt N3 aka APPJ..... highly recommended!

if ever na may available kang tube pre amp try mo lang lagyan yang AAPJ sir! Na try namin ni sir RXV sa bahay nung nag jamming kami and parehas kami speechless sa laki ng improvement nya...kaka gulat :o

@estaana
Glad to hear you're happily addicted to the fullrange experience hehe :)
@xbase
Sir, based on given specifications, power consumption is 38 watts , so you'll enjoy hours of listening pleasure without fear of increasing your electric bill :)
@remington
Oo nga, paired with a good tube pre-amp (like Remington's), gumanda pa lalo gain and details.
Papag-ipunan ko rin yun bro :)

Question lang po. Ano best Audio source and speaker combination that is currently available sa market?
Sir, medyo subjective kasi ang question, for me it depends on the listener's taste/preference e.
For me, I'm currently connecting it to a PC via DAC then to the AAPJ tube amp, powering an 8" fullrange speaker set. I've also tried it on Audio Nirvana Super 8 and had great sound coming out of it (with surprising bass output). Gusto ko rin i-try with Markaudio fullrange next time :)
For me, a speaker with 90+ sensitivity will truly sing with these mini amps.
If you're into smooth jazz, vocals, instrumentals, classical music, this is the way to go (for hours of critical listening).
If you're more into rap, rock and heavy pounding bass, I'd advice you to look elsewhere :)
-
sir rxv, maganda din sa rock ang el84, at the right amount of volume for the appj set. the guitar really sings...

may mark audio chr70 ako dito sir RXV pero still burning pa around 55 hours palang.

Actually ang ganda tono ng guitar and strings, it's more of the heavy bass that lacking. Of course, I can't expect a fullrange to do a subwoofer's job :)
@Remington
Wow, sarap siguro i-session ulit yan :)
Natetempt tuloy ako magkaroon ng Alpair10p's :D

After weeks of research, I was convinced to give this amp an audition. I brought my gears to RXV's house. I mean all ha ha ha. My main concern was my 88db sensitivity speakers.
Well, what a wonderful visit it was. RXV and I hooked my gear up to his APPJ and it was magical. True S.E.T sound. I am used to my Sun Audio SV-2a3 and to be impressed with this tiny tube amp is not just an enthusiastic comment of the moment.
Today, I finally hooked it up at home. Wonderful depth and clarity. Palpable presence in a small but proportional sound stage. In near field, I can really sense the air it provides. The recording venue is faithfully recreated. Bass is solid and full.
At 88db, it was reasonably loud. Louder than I care to play at near field. On some tracks, the volume is almost maxed out. But for my ambient music level while working, 1 o'clock position is fine. For delicate small room acoustic recordings, this is very comfortable. For large and high impact performances, a 94db or better speaker will be needed for scale.

sir RXV,
Very much interested in this amps but have very liitle knowledge with tubes. I have an AMX Aria EL84 but the configuration is SEP [Single Ended Pentode].
My question is 'Is this really as SET [Single Ended Triode]?
Thanks

^ I am in the same boat with sir Gino, my main concern too was the sensitivty of my current speakers..I would really like to demo it though..malayo lang talaga si sir RXV at hindi ako familiar pano pumunta dun hehe..napa isip ulit ako sa post ni sir Gino

if the EL84 screen was hooked up to the plate of the EL84, then it's a triode SET,
bear in mind that wiring the EL84 as a triode results in much lesser power
than is available than when it was wired as a pentode....
-
Can this amp be wired for pentode or UL? Interesting. I wonder if this 3.5wx2 tube can produce as much power as T-amp.... I used to use a Dynaudio Audience 42 with a Dayton DTA-1 with very good results... Interesting considering I have a stash of NOS EL84 tubes....

try it together with a pre amp and you'll be surprise of the power and the quality of sound it will produce I and sir RXV have tried it first hand and we were both speechless...nganga kami parehas ;) >:D >:D

thank you sir tony, i'll give it an audition [when schedule permits] to hear the difference between the two configurations.

UL wiring a pentode is a circuit trick designed to get triode like power output
(triode sounding)with pentode like efficiency...
pentodes came about due to the craving for power when low
sensitivity speakers came about...
and this is also how the push-pull amps came to be...
as always, it is your speakers that will determine if this amp is for you or not.... ;)

I read in one of the forums that one the Almarro a205a 5W x 2 EL84 is a match made in heaven with the LS3/5a 81.5db/Watt speakers. Watts are only numbers. I believe 3.5W/ch can truly sing.
I have driven a Dynaudio Audience 42 86db/W with a 10watt/ch T-amp for some time along with a HRT microstreamer DAC. It was one of the cheapest, best synergies I have encountered for the price. The trick was to use a high voltage source (2v or more RMS) such as a CD player or DAC. If you use a low voltage source such as a Mobile phone you'll never get decent volume.
I agree a dedicated pre amp would put this tiny amp on steriods. Tempted to try this tiny amp with a high voltage tube preamp. Its also a tube rollers delight since it only uses a single 12ax7/5751 tube.

@Gino
Thank you for your wonderful and analytical personal review of the tube amp. I'm glad it integrated well into your system. Nagulat din ako sa Denon bookshelves mo, they were pretty small but surprisingly sing beautifully. And for such a small enclosure, the bass is surprisingly evident.
@fredreadrick
Based on manufacturer specs, yes it is S.E.T.
For some reason, I also tried different types of amps from SS to tube amps like push-pull, pentode, hybrid, and for unexplainable reasons, I still ended up going back to this SET. Yes other tube amps such as push-pull may have more power and grunt, but the sweetness and right amount of airyness brings me back to this humble amp. I feel it really depends on proper speaker-amp matching, nagkataon e sineswerte lang ako :) Of course audition talaga is the best for your own judgment.
@disturbed
Sir you can visit me anytime naman and bring your own speakers just like sir Gino did. My place is in Antipolo but at the lower part lang naman, just 2km from Marcos Highway, so hindi aabot sa bundok :)
Usually hindi naman traffic dito huwag lang rush hour or raining. Either from Makati/Fort or Quezon City, it takes around 40 minutes to get here kung light-moderate traffic.
@geevee
About the Dynaudio, I'm not really sure, since demanding talaga ang speaker na yun, but we could pair and audition it para magkaalaman na. Based on my experience, not all speaker's sensitivity ratings are accurate. I once had a 90db speaker being bested by a 86db speaker in terms of sheer output. I believe more on speaker-amp matching, and just trying it out is still the best way to know. Also, yes I agree to your comment about the audio source, the difference can sometimes be night and day if properly implemented.
About the tube rolling, yes I also started venturing into this, and different tubes give out their own character nga, that's the good thing about tube amps that cannot be done with SS and T-amps. The only down side here is the hole in my pocket :P
@remington
Yes sir Jun, that pre-amp really brought this amp even further, parang na-turbocharge na vehicle. Makabili nga :)
Actually because of this, napagastos ulit tuloy ako. I'll soon be matching my other personal APPJ with a new speaker project... Next time listening session ulit tayo :)
-
mga sir share ko lang... sa experience ko best match nga APPJ tube amp sa mga high sensitivity speakers... I use it sa vintage 12 incher panasonic fullrange rated at 93db in open baffles augmented with twin subs, the sound delivery is very nice, very organic, para kang nasa live acoustic venue lalo na pag mainit na ang tube amp...(parang diesel engine pag uminit lalong ganado)...
Used in rotation is another vintage 10 incher coral fullrange rated at 95db.... halos same sound delivery. and another vintage 8-incher foster (fostex) fullrange at 95db (which i sold already) dahil I needed funds that time.
I used to own different high wattage branded SS amps and even a t-amp, and several popular brands of commercial speakers in the past.
my observation: 3.5Watts per channel ng APPJ (for me has enough volume) mated to high efficiency speakers... but i also want/plan to try adding a tube preamp one of these days and hear what happens....

unless i hear it for myself, i will treat such comments as opinions, of course YMMV...
-
I concur.
I am using an APPJ with 88db/1w/1m Denon SCM51 4" speakers and an active 10" sub. The system has very limited headroom.
It gets realistic with acoustic sets like trios, guitar gigs, and small studio recordings. Upright bass and specially tube guitars and bass guitars sound really accurate. Jaco Pastorius comes alive.
It loses steam with expressive pianos, drums sets, choirs and orchestras. It just cannot reproduce the scale with my 88db/1w/1m speakers.
To me scale only comes with critical listening. For everyday ambient desktop music, the combination is perfect. It's louder than I can stand to hear continuously.
-
sir what would be an ideal pre-amp to APPJ? considering the cost of the amp, im assuming there's a pre-amp near its price range as well.
thanks!
-
I like to know too since I've never owned a preamp. I want more headroom for my Chesky and audiophile cds.

tube types of course.....a preamp may add more flavor some people like, again YMMV....
-
Thanks for the feedback sir Gino. As for my experience, the APPJ is very well suited to high sensitivity speakers, such as my 8" Royal Copenhagen fullrange (95db), I usually listen at around 12 o'clock, which literally fills my entire small room (4 x 4 sq/m).
But now, I'm already mating the APPJ with a Markaudio Alpair 10P (90db) with good results. Although it's still in its break-in stage and without the proper enclosure yet, maganda ang pagka-match, tamang tama lang.
Also, I'm testing the APPJ with a Markaudio Alpair 7 gen3. This driver has a very low sensitivity of around 85db. But when used in a small room, kayang kaya pa naman ng APPJ, but of course don't expect heart pounding dynamics from this match. But still, it's really good, especially in near field listening and small rooms.
Heavy rock and metal and loud music in my opinion is not the forte of both APPJ and fullrange as well anyway. Jazz, acoustic, classical, voice, and critical listening, wala ako masabi...
-
@stockHT
I already was able to try and mate my personal APPJ with sir Tony's tube preamp during my meet-up with sir Remington in his setup before. Without any bias (or solicitation), malaki ang linakas ng output/headroom, parang tinurbo-charge ang APPJ (gulat din ako e), while maintaining composure and cleanliness of sound.
But then again, a tube preamp may add some flavor/coloration (also depending on the tubes that you put). But in my opinion, during that time, my ears agreed to the sound of music.
This is also one of my future upgrades that I plan to pursue when I have the budget (as well as a larger room).
-
I like to hear those speakers when you are done.
Haha when I get to finish the proper enclosure sir, right now kasi gumawa lang ako ng temporary OB enclosure just for breaking-in the speakers. Sobrang busy ako right now, so hindi ko rin maasikaso. By that time, properly broken-in na siguro :)

Haha hindi naman sir. Actually the Alpair 10P is mine, while the Alpair 7 is going to be used for car audio in the near future. Binu-burn-in ko lang sila using the APPJ's strictly following Mark Fenlon's burn-in low volume procedure.
Sa susunod na ang enclosure kapag may time na akong gumawa. Pensil din siguro :)

The past days I had the chance to connect a vintage pioneer SS preamp featuring only gain for the left and right channels, no bass knob, no treble knob, no loudness switch.... I can say there is really an improvement... para nga nag transform, parang nakaturbo hehehe,,,pag mas ilakas ang volume parang mas sweet sound tunog nya (eto ba yung even? harmonics ng tube amps?). wala ako tweeter gamit pero ang kalansing....

Pwede na. But not the best combination. I think 94db and up is the way to go for more driver control, scale, and impact.

I'm currently driving my Markaudio 10P (sensitivity of 89.7 db) with my APPJ, temporarily in open baffle enclosure habang wala pa akong nagagawang proper box. In my 16 sq.m. room, it would fill the room with music at 1 o'clock poisition. Normal SQ listening levels for me (around 2.5 meters away) is 12-1 o'clock position, anything louder than that is not comfortable for me anymore (for critical listening anyway).
I actually have a monitor audio RS center but I didn't try connecting it to the APPJ since it is only one piece, so hindi ko nasubukan for stereo use.
If you want, you could try it out at my place and let's see how you MA BX2 matches with the APPJ.
But take note, audition/testing lang ha, I don't have any more APPJs on sale hehe.

Salamat mga ser!
Meron bang entry level speakers na atleast 94DB ang sensitivity? Bookshelf lang sana para makapag simula ako magsetup din ng SET. May marecommend ba kayo mga ser?

Best bet mo is DIY. Pasok ka ng drivers. Audio Nirvana 8", Fostex FE206EN (8") or FE166EN (6.5") or FE126EN, Visaton BG20 (8"), Lao Cao 8" and 6.5". RXV is experimenting with a Markaudio 10P (91db).
AAudio Roman seems to use the BG20. Ask Anthony kung mayroon pa siya. He had single and array models.
Kung bookshelf, you will need a sub to get proper bass. Not always but most likely.
Lastly, sold out na ang APPJ on this thread. You will have to bring in your own.

Salamat ser Gino. 8" ok na ba sa 4x5 meter na room? Are these drivers available na saten or online pa din?
I was looking for bookshelf kase maliit lang ang listening room. Napatingin ako sa single driver speakers. Mukhang ok din. Klipsch speakers meron din silang bookshelf na high sensitivity. Will research pa. I like this mini set amps hopefully makakuha soon para ma try..

I heard the 8" Copenhagen speakers in a similarly sized room backed up against the wall. Sounded very good. Full bass. Some guys have heard the APPJ with Audio Nirvana 8". Very positive reviews.
Yung Fostex 6.5" ko bitin ang bass. With a sub it sounds fantastic. A member bitin din sa bass ng Fostex FE207E niya in bookshelf. 8" na yun. You will need a sub for it to sound right or live with the bass it offers.
Truth is, Floorstander and bookshelf will most likely occupy the same foot print. Mabigat lang sa mata ang floorstander and mabigat literally.
Here's my room with 6.5" fostex and 8" sub.

Hi Ser Gino,
Nice setup! Ano yung nasa taas ng bookshelf speaker? tweeter? Gusto ko ng bookshelf para hindi din mabigat/mainit sa mata. Andito pa kase ko sa Iran so mas ok saken na puede ko iuwi kung babalik kami dyan ng walang hassle. Mas malaki ang room mo compare sa room ko at madami din gamit. So, mukhang ok saken ang bookshelf. Medyo mabass yung lugar kung nasan ang setup ko ngayon dahil nakapaloob siya at makipot..

Nakapagtanong din ako about Fostex FE206EN dito. Aabutin ako ng $600 kasama na lahat. Meron din kaseng mga DIYer dito. Will check differences ng FE126EN/FE166EN/FE206EN online. Ang 6.5" na drivers ok na siguro sa lugar ko ano? Makapag research pa ulit. Balak ko bumili ng amp dyan na sa pinas. Dapat bibili na ako last month at dito ko papaship pero nagbago isip ko baka magkaproblema pa. Will get a PP then get this Mini amp din soon.. APPJ or LM mini 218. Isa isahin ko muna. :D
Salamat ser!

Yung sa ibabaw ng bookshelf ko ay Fostex supertweeter. It adds presence. But I enjoyed my speakers without them for many years.
Go over the box size ng seller mo. Kasi even the 6.5" has a relatively big bass reflex box. The 8" even bigger.
Pa pm naman links sa work ng sellers mo. For inspiration.

Sent PM ser. :)

Possible kaya na magkaron ka ulit nito sir?
Thanks

Nothing is impossible...
Maybe in the near future :)

sir what would be an ideal pre-amp to APPJ? considering the cost of the amp, im assuming there's a pre-amp near its price range as well.
thanks!
share ko lang mga bro latest experience ko with my own appj minitube amp. recently i got hold of a headphone amp and tried to use it as pre amp to feed the appj. well, there is a considerable gain! the effect is just like what bro. remington has been preaching. parang naka turbo or steroids. the secret is you need a gain stage for the appj.
good thing the headphone amp is almost the same size wise with the appj. so di masakit sa mata tignan. i had tried before a vintage pioneer pre amp with excellent results but napakalaki ng size compared to appj.
you can try mura lang naman headphone amp, wont cost u an arm and a leg
:)

Kala ko me available na ulit. Excited to get one pa naman.
Baka meron gustong mag-benta ng unit nila. Interested here ^-^

Fostex FE126EN 93db and APPJ, bagay na bagay.

Nagtaka ako bakit nalipat itong fs thread yun pala sold out na at naging discussion item na. Kudos to the mods.
-
I have lots of nos 12ax7 singles for these appj's, let me know if you need any to roll. Mullard, Matsu, Toshiba, G.E., etc
which ones did you find to your liking?
-
Oh, I didn't know that this was moved into the discussion thread na pala. I will change the subject title na lang to make it more appropriate.
-
Buti di nilock ng mga mods. Wanted this before wala lang extra dough.
-
Yes, thanks to the mods for moving it.
This is truly a deserving tube amp for P13,838. It is a mix of old and new. A tube amp with a modern switching power supply. That makes it compact.
-
Gino, Where did you see the P6k+ price? Usually nakikita ko on Ebay is either $189 or $234 e, shipping/taxes not yet included. I actually saw a new version of the APPJ which is cheaper, but it is smaller in size and has a different set of tubes used (slightly less powerful rating). It's rather cute though.
Yes, for me it is one of the best quality "true" tube amp for P10k-below range. For its price, I haven't seen anything more value-laden and sweeter than this one (and let's not forget "tune-able", because of possible 1 piece 12ax7 tube rolling)
Yes, there are cheaper options out there such as some hybrids, class-D, or solid state amps. But for my personal tastes, nothing beats old school goodness when it comes to clarity, smoothness, warmth, and naturalness that a tube amp provides.
This tube amp certainly deserves recognition and respect in its own right.

A small article about this amp:

My mistake RXV. I computed $89 instead of $189. New computation becomes P10,764 for amp and shipping. Local customs assuming 10% tax rate amounts to P3074. Landed cost from Ebay is P13,838. It is still a bargain for what it delivers.
-
Haha sayang, I thought prices went down na.
BTW, here's the other APPJ version that uses 6J1/6P1 tubes. Cute little bugger.

But I still prefer the older version. One reason: "12AX7". So cheap and easy to find for tube rolling. It never ends :)
-
It's cute but not my type.
-
Hehe, I too still prefer the old style ;)
-
Installed JJ EL84. So far I am liking it. I am not tube rolling. I just replaced the defective ones.

This amp sounds wonderful with my Hifiman HE-400S headphone.
