Pass XA30.5 enough power for Wilson Sophia 2?

Semi,
Those are all good questions. Could you start a different thread? This one is about Pass XA30.5 and Sophia 2 speakers. Thanks.

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.

Input impedance is low in the Pass XA.5 amps. That could be a factor.

Only if the output impedance of the preamp is high, which we don't know because the OP is AWOL.

A lot of (most perhaps) preamps have output impedance that is too high for the Pass.
