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.
Heard XA-160's on the show for about an hour or so ... with Avalons ... I think you can't get much better than Pass XA series independently from the price range.

By the way, an american guy, who is director of Vienna Opera music archieve here in Vienna, uses XA-160 (with Watt Puppies 7) ... and this guy has a real budget at his disposal. Simply, he couldn't find anything better, he said.

So if you have cash - go for it ... that is probably the end ... and if not, then probably very near to it :-)
Hi Honest1. I will not be upgrading from the CAT, I'm looking for a cooler running alternative for the summer months. I recently bought a Pass Aleph J, which I think works quite well with my Merlins - they do not need a lot of power and the do not need a lot of damping for the bass. I am however, wondering if moving to the XA-30.5 would bring any improvement over the J - it might not given that the J is very easy to drive with a tube pre and it has low damping which is a good thing with the Merlins. Has anyone actually auditoned the J and the XA-30/.5? I'm also assuming my Joule 150 MKII will not have a problem with the 15 kohm input impedance of Pass, I know the Joule OTLs have an input impedance of 20 kohms so it would seem this should not be an issue with this tube pre.
