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.

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 :-)

Pubul57,

If this can be of any help to you ... I tried Pass Labs X150.5 with my Bent Audio passive TVC. As you know passive TVC's are even more critical to amps input impedance than tube pre-amps. I used RCA (11 KOhms) and XLR (22 KOhms) inputs of Pass Labs X150.5 and couldn't hear any issues on any of these two configurations. It was working just fine in both cases. So I guess you will not have any problems either ...
