Which one is the cleanest sounding kit?
No negative feedback. Like stasis..
Forward vocals. Melodic mosfets. All that.
.and how much. Need around 2 pairs of output transistors per channel for daily use. 100 watts roughly
I had adcom 5500..and 5800. The lack of detail was depressing..I don't think Mr pass designed those. But definitely dont want that inflated huge bass and no detail. I like melodic smooth sweet piano on those mosfet amps.
I want something like nakamichi stasis ta, Sr series But with mosfets. Basically something that would retail for 2000$ in 80s(or 5000-7000$ today) once labeled "nakamichi", but I could build it at home for 100$ with "Richard james" label

Erm aren't they All 'cleanest sounding' more or less?
Few if any Dogs in the stable
Biggest variable IMO is the Source AND the speakers one powers.
Massive quality variations there.
Ferrari engine fitted into a Bus.. is likely going to be 'constrained'
I agree.. but some amps are totally different. Nakamichi re-1 for example sounds a tiny bit like through the fog compare to say ta-3a. Then there is adcom 5800.. which is a bass mashine. . But least detailed amp I've had in my life.
Luxman r115 is real flat. But lacks that beautiful low tremble, high midrange flavour of nakamichi ta /sr stasis amps.
Those observations I made having had multiple samples of each amp
.clean and untouched.. (yes Thst ta-4a That I got and I believe u were the one beaching hystericaly on that thread) was messed with. . Not in verginal state. So I don't include it in list of observed amps signatures/characteristics.
In general I agree big improvement is in source and speakers That will have enought power.
Bigest difference I noticed is mosfet powered amp.. and transistors. Adcom 5800.. sounded very sweet. I'd keep it but it has no DC relay.. and internals look like scrap metal from home depot. Diy amp basically

A nice power supply for a 100 watt amp will likely cost nearly that much, too.
They key is looking at all the individual parts and going "well that is only about $100"
This is a Class A 100 watts output per channel amp we are talking about?
Does your calculator have a 'multiply' function?
You must have some big ears to go with that big mouth?!
Papa did indeed design all those 5xxx series of Adcoms, but Adcom beancounters conspired to strangle ALL the class A out of them (except for maybe 1/2W). So you just need to twiddle the class A pot and add it back. And with a used GFA-5300 (2 pairs of output mosfets, as requested) you could add a fan or some more heatsinking, plus some more PS caps, and you'd have a decent class A amp for $100 which met your spec. And no need to build it all from scratch...

Yes. Very cute sharp sarcasm there. I'll see if I get a nice sample of 5200 or 5500. With all respect to stasis and Nelson pass.. it's still hard to debate adcom are diligently implemented.. a LOT of people blew their speakers with those amps.. Ill only plug them in after dc relay install. Or only use them with whatever speakers. No one ever had such issues with the way Japanese implemented Nelson passes ideas. So basically we should all be mature enough and stop being blind folded fan boys.

I get it!
Your request for ideas to implement a d.i.y. high powered Class A amp for $100 was an ironic mocking comment on the Pass d.i.y. crowd ...sort of a 'performance art, DaDa' thing!For myself, it's all fun and entertainment - if my build makes sounds instead of smoke, I'm quite happy, so long as I don't have to spend a LOT of money.
I get it!
That's about how I took it, too, but was hoping he'd put a pencil to paper himself to discover how far that $100 would get him.
It is possible to have a clean amp for $100, but it must be class D. WalterW, a respected member who built a lot of top quality class A Pass amps mentioned B&O 50ASX2 is an excellent class D that can be comperable with his Class A amps, and it is sold for $70 on Ebay. I bought one based on his recommendation, and I comfirmed his words. It is surprisingly good for the price. My Alephs are better, warmer, hotter, but it costs 10 times more to build one.

As I think I said in my first post a friend suggested the BA-3 complimentary. He also suggested the Tubelab SSE. Today I stumbled across the F5, not the F5T, and read through the build guide. It really looks like the instructions are very detailed and explain every step of the way as thoroughly as they need to be.
I'm holding off on the BA-3 but since I have the Universal Power Supply I'm part way there already.

Ok...its been a while since anyone has contributed to this post and I have question about audio quality for the various Pass Labs DIY amps.
Are there significant differences in the sound that these amps produce? Which one would you say sounds the best? And which one doesn't sound so good?
Additionally I imagine it also depends on the components used in the build?
Any comments?

And my big brother can beat up your big brother any day of the week. So there.
Unfortunately your reply and mine has no relevance to the question I asked.

say that you're comparing girls , all in same weight bracket , everything else being different
say that you're loudspeaker
which girl you'll prefer ?
speaking of FW amps - all of them are in same quality range , some are for sissies , some are not
though , questions as these are more suited to FiFi forums ( talking about synergy) than to DIY forum
ask specific question - which of FW amps will most suit my XX speakers in roomm XX big , with my listening (XX SPL) habits

I perceive some small differences in the sound in my FW clones, but not huge. I would let your speakers requirements dictate what you build.

Point taken. I do know that just the amp is not what has an effect on sound. And do know that 'sound quality' cannot be quantified. It's all a matter of personal preference and as you stated, the synergistic effect of all of the components together.
I guess I was thinking that perhaps...because of the complexity of the design the amps that are more 'involved' would somehow be perceived to have a better sound.
