Anybody ever audition the Pass XA series amps?


I have setup a home audition of pair of Pass Labs XA-100's to drive my MG-20r's midrange and ribbon tweeters in a bi-amped arrangement.

I'm quite excited to hear what they will sound like compared to my Pass Labs X-350.5.

So, here's my question, is their any GON members who have heard the XA amps? If so, what was your opinion of their sonics? If you also are familiar with the sonics of the X-.5 series, how would you describe the difference in the two amps sonic signatures?

Thanks, in advance to anybody who can share.

You're lucky to be able to demo these amps. When I wanted to upgrade from my Aleph 3, the only Pass dealer near me never had anything to demo, even though he was running ads here selling the stuff!! I ended up buying a pair of Atma-sphere MA-1s. I would love to hear your results. PLEASE keep us up to date with your findings!!!
Wanted to revive this thread as I too am interested in the answer, especially compared with some tube amp alternatives. I currently use a CAT JL2.
Pubul - One of the best systems I heard at CES (or anywhere) used CAT monoblocks (along with a Reimyo CD Player and Ascendo speakers). They will probably be tough to upgrade from.
