Are Pass Labs amps probably the best ever you can buy ?

Here's a list of Pass amps with no feedback...
F1, F1J, F2, F2J, F4, M2, SIT1, SIT2, SIT3.

Those are all amps that will drive an actual speaker load. I'm not sure you could even call a .3 watt amplifier a "flea power" amp. Perhaps "microbe power" amp would be more accurate. I really don't think the ACA should be considered much of a measure of what characterizes Pass amps. That is an amp designed first and foremost to be VERY easy to build. "Professionally" building an amp designed to be put together by a 12 year old doesn't strike me as a monumental achievement. It doesn't sound like you know much about Pass amps. Go try a SIT, a J2, or maybe and F4. That F4 is designed for line level stages like you're working with to enable them to drive an actual speaker load.

So you like the Pass 250.5 better than Classe CA2200 ? I ask because I own the CA2200 and like it very much.. No one talks about it at all despite the good reviews.. Which leads me to maybe try something else now because, just maybe, the other stuff is better ?????  (Pass, Ayre, Bryston, and everything else in the same tier)..


anyone else can answer if they have experience with CA2200 .. By the way the Classe beat Parasound A21 in my system, my ears..

I liked the recent interview with Nelson Pass in Stereophile (I think it was Stereophile)...his constant experimentation with his gear and sharing designs with the DIY/Burning Amp crowd is cool. He built a gizmo to add in "even harmonic distortion" to an amplifier (He gave some of these things away at a "Burning" gathering) as part of a theory that that he feels makes music sound more musical...or something...all validating the mysteries behind my single ended tube amp sounding better than any SS amp I've heard. Pass is the rare open book designer who writes his own manuals and shares pretty much everything he does and is funny and seemingly less of an egomaniac than many great designers out there.
