Pre/power or Int Amp for Wilson Sophias?

On the solid state side you should give Rowland and Pass a listen. I've heard the Sophias with both and they are a good combination. If you do tubes ARC is always a good choice (lots of punch, great bass but never edgy or bright). You might even consider a nice BAT integrated and put a little more money in cables instead.

Good luck, you have the beginnings of a great system on your hands.

I've had great success with the BAT integrated, as well as BAT separates on my Sophias. Nuforce also works great with them.

I did not like Bryston on them. I owned the Concentra II, but didn't have my Sophias then---its a great unit, but definitely not tubes. Wilsons tend to go well with tubes....that said, i would like to try out the Ayre integrated with them.

I use Ayre on my Sophia 2s...they are a wonderful match...

I have a pair of Sophias and have tried a bunch of solid-state and tubed amps. My preamp has always been a CAT Signature Mark III. Since these speakers are a relatively easy load you can use either tubed or SS amps with good effect. I had an Audio Research VT100 Mark III and got a huge soundstage with great bass, same with a Conrad-Johnson Premier 140--you could also go with a MV60 amp which shows up here on Audiogon for less than $2K. If you wanted solid-state you could probably get good results with any good amp. I ran mine with BAT VK-500 and VK-600 amps and had good bass, immediacy, smoothness. The only drawback is a relatively small soundstage compared to the tube amps I tried. Right now I am driving them with Essence amps--if you ever see any of these on Audiogon I would highly recommend them--best sounding amps I have ever heard.
