what amp would maximize wilson sophias

One good choice that's reasonable (well, you know) is BAT's integrated amp. Get one of the tube input stages, and you have quite a front to go with your Cary. This is less than your request for 300 watts, but the quality of the power and the preamp stage is amazing.

Michael,

While I'm more familar with the WP, after reading what Duke wrote it appears the Sophia may be a similar challange to the power amp. Don't get to caught up in watts, current is the real issue. I use a ML 335 and it doubles it power at 4 ohms and doubles it again at 2 ohms. So, while it's only rated at 250 watts it really delivers the juice when the impedance drops, which is when you need it with Wilsons.

While I know there are many tube lovers around here I can tell you with my WP 5.1's the ML 335 mopped the floor with my old ARC VT 100mk2. The ARC unit just didn't have the power to control the WP's. My point is unless you go with a massive tube amp you won't get where you want to go. Kleech may like the purity of the Nagra, but he is giving up dynamics to get it. While this is a personal choice, I suggest a tube pre and a transistor power amp. Some of the older Roland stuff would be an excellent choice. I'm real happy with my 335. But get one that doubles it's output as the impedance drops from 8 to 4 to 2. You have lots of choices on pre amps, I also use the CAT Ultimate.

Get you power amp first and then find the pre amp that has synergy with it, your room and your taste.

Michael,
I too have just acquired a pair of Sophia's. I have been running them with Pass X-250 connected directly to a Wadia 861SE via all Valhalla cabling. The sound is extremely dynamic, superb low frequency extension but a bit dry and analytical to my tastes.

I considered adding a tube pre (CAT or BAT balanced), changing cables (Transparent Reference XL) or changing amps.

The decision I made was to acquire a single BAT VK-75SE and if it's a step in the right direction, I'll add a second, and run them as 150SE's. The first amp is due to be delivered on Tues.

I also will be auditioning a friend's Shunyata Andromeda s/c to compare to the Valhalla's.

I'll let you know my findings.

I have auditioned the Sophia's with ARC tube mono's, tube pre (don't remember the model) and CD3 player and they were fantastic. Great bottom and smooth top end. The best I have ever heard the Sophia's sound. I have not listened them with other tube amps but have listened with ML gear. They were a bit dry with the ML.

I'm with Rcupka (nice choice).

Get a BAT VK75SE, and turn it into monoblocks later on if you need too. Have heard it on 6s and didn't feel the need for more power.

I also have heard the Sophias on VTL 450s, another superb choice.
