Pass XA30.5 enough power for Wilson Sophia 2?

I was wondering about this combo. I have a very large room. Personally I dont think it's enough power but what do you guys think?

Some tube preamps =may= be too high, but I'd be surprised if any solid state units are. I think your statement is a distortion.

I did once use the Audible Illusions 3A with the Aleph 3, which I think was 10kohm input impedance, and the AI3 was realtively high outut impedance, and I did not notice any problem driving the load. I would say that 95% of preamps should be OK with the Pass, it is an issue, but is not likely a problem with most, if not all, preamps - certainly not ideal for those seeking a passive path to preamplication.
