BAT or Pass With My Sophia 2s?


A'goners - I'm considering a system reconfiguration with an upcoming move to a new residence. For those of you with experience with BAT and or Pass gear with Wilson speakers, please comment on your experience. While I'm very familiar with BAT gear, I am curious about the synergy of a Pass/Sophia2 combo. Also, please recommend the amp and pre in each line that you think would be the best match.

Thanks!

Keith - the Ayon is a keeper, and I was planning on using it in an upstairs listening room. The reason for considering solid state is that the equipment behind the Sophias will be going in a closet, and I'm concerned about the heat from a tube based amp. I know the big BAT amp (VK600-SE) runs hot, but not nearly as hot as my Triton.

Thanks for the comments so far - anyone else?
I have both: a pair of Pass XA 100.5 monoblocks and a VK-600SE.

My speakers are Wilson Sophia 2. Preamp varies between SS and tubes (I'm still searching...)

Both are great amps. The differences to my ears:

Pass:
- Better midrange
- Thicker, more tube-like bass
- Warmer presentation overall, not much in the way of 'air', but highs are very smooth

Bat
- Bass is much tighter, less overhang
- Midrange and highs not as smooth as Pass
- Leaner presentation with much more air

At the moment I prefer the Bat, but both amps are great.
Meant to add that if you're going with a tube pre, the Bat would be the one I recommend.
Madfloyd - thanks for sharing your impressions. Thinking of going VK600SE and Rex preamp. Any experience on your end with the Rex?
