Pass XA30.5 enough power for Wilson Sophia 2?

While the XA30.5 may convey a loud enough sound with your speakers, I would be apprehensive if you listen to complex music and if your room is large. Power and class A gives a sense of effortlessness, unrestrictedness, and control. Sure, the XA30.5 has some class AB headroom, but the amp is really about the class A portion up-front.

My opinion is the XA60.5 at a minimum, but the 100.5 or 160.5 may be even more appropriate. The Wilson/Pass combination is not uncommon, so you may call some dealers and check-out the systems page.

Pass and BAT are both great SS options. If Madfloyd changed only the amp, and hears what he hears, then it is hard to find fault.

I concur that in my system, the Pass provides phenomenal bass, at least when there is sufficient power. It is not a 'fast' bass, which I personally do not think is accurate. The Pass most definitely takes firm control of the woofers. It would be interesting to compare the BAT to the XA160.5, but there would be an obvious price differential against the Pass.

Reno Hifi has a home demo program on Pass Labs, and is a real asset for those looking to form their own opinion. I feel that the restock fee and terms are quite reasonable.

Always be aware that even used amps need a few days to warm-up when boxed. If you were to evaluate for a short time, I would suggest leaving the amps on the entire time.

Can you match the Pass amp with a tube amp? Yes. And I highly recommend it. It will give you the best of both worlds.

Do I ever wish for a tube amp with this combination? Absolutely not.

Sorry. Meant to say pre-amp, not amp in post above.
