amp for low volume listener w/ wilson audio sophia


I am looking for new amp and preamp to replace my current system consists of Krell KRC preamp and KSA-200S amp to go with Wilson Audio Sophia speakers. Krell sounded brite but excell only at loud volume around 12:00. I prefer listen at lower volume around 9:00 pm to 10:00 pm position and wonder Pass Labs amp 250.5 (new) or 350 (used) meet my need? Should I get these?

Thanks.

I'm not sure about match with Sofia but Class D amps are known for very good sound at low levels. I listen soft at late evening and was amazed by performance of my Rowland 102 (Icepower). Later I found few people mentioning the same thing about their class D amps.
I recently moved from Krell to Pass Labs X1 & X250.5 to power a pair of Wilson Sophias, and have been very happy with the change. I've also heard this PASS combo powering a pair of Wilson W/P 8, and it too sounded excellent. PASS Amps seem to be a very good match with Wilson Audio Spkrs.
I need to find out which amp classified as class D and I definitely looking into the Pass Labs gears. Thanks for response and sugguestion.
