Pass XA30.5 enough power for Wilson Sophia 2?

i agree wtih Rtn1---the whole point of this amp is Class A 30 watts. the A/B headroom is pointless imo

Tvad- then if he got the BAT and the bass issue was resolved, how was the muddy bass not from the amp? Just curious as I don't understand your comment---on your speakers in your room, things are obviously different. Perhaps he has a huge room, i don't know.

I've owned the speakers, but neither amp so was trying to refrain from comment. Personally, I've never liked Wilsons with SS, with rare exception. BAT 75SE was superb on my Sophia Is. So do VTL 450s.

I personally think the 30.5 will be dynamically challenged on that speaker. on the SS-side, I had a Bryston 4BSST and didn't think it was that powerful sounding on that speaker.

Tvad- don't normal tube preamps have high output impedance, and as you said Pass tends to have very low impedance---therefore, tube preamps *in general* aren't a great match with Pass? Fully balanced preamps tend to be different--as I've noticed they have lower output impedance.

Krell for instance on the other side has high input impedance making it pretty universally acceptable to tube preamps, so could be a better option for SS.
