The imperfect amp: Pass or Ayre?


There are two high end SS amp brands which, from a technical perspective, don’t do very well, which I am thinking of:

Ayre and Pass.

Pass has stated that even ordered distortion is euphonic. Ayre’s zero feedback, diamond circuit has a great deal of distortion compared to the very best measuring amps.

I have to admit, that like an IPA vs. a Belgian White, I have a very strong preference, but my preference is not canon. It is just how my wallet moves me. You should in no way feel like my tastes matter. Buy what makes you giddy with joy.

Would you, kind lady or gentleman, tell us if you have heard both, what did you think?? Is this to narrow? Would you throw another brand into the ring??

Bob, the KXR/20 is one of the best preamps made I feel.  It's Ayre's best product to date IMHO as well as most others.  It's a special piece. The MXR/20 upgrade is awesome, but not in the same league as the KXR.  That said, the preamp is more important than the amp, so that would be the upgrade I go with.  The literally use only the case and connections.  The rest of the unit is brand new.  The may still use the transformer.  It's basically a brand new unit though.  I have seen them make them.  Hope that helps a bit.  It's a 30k preamp for a reason.  I dream of owning one.  
@atmasphere  I think the weighting system is a splendid idea and certainly a tool designers could develop internal to the firm as a way to score various designs. We used a weighted multi variable trade space to evaluate designs for Aerosystems, etc
depending on what design you’re focused on, Pass doesn’t just make some of what he does transparent, he makes all of it so. So many of his circuits are totally laid bare for people to read/analyze/copy/modify. His support of DIY makes the high end audio world a better place.


@cal3713 All very true!



1- I truly dislike IPAs to the point I won't touch the stuff. Give me any variety of other beers please. 

2- To my apparently flawed ears, I think Pass makes superb amps and pre-amps

3- haven't heard any Ayre gear in at least a decade so my experience with Ayre is out of date

Which is why it is the perfect analog for this discussion, especially since you are wrong.

(I'm joking!!)
