Amplifier advice for Wilson Sophia speakers


I'm looking for a Pre-Amp. & Amp. for my Wilson Sophias. My room is 20'x26', with good (flat) acoustics. I listen to Acoustic Rock, Jazz, R&B and Blues Rock, live recordings whenever possible. I'm considering the following:

A) ARC LS16 MKII & ARC VT100 MKIII
B) VTL 5.5 & ST150
C) Pass Labs X2.5 & X250
D) BAT VK-300xSE

I listen at fairly loud/realistic levels, so I need to make sure that the system is moderately powerful.

Any advice would be greatly appreciated...Thanks!

I think the X250.5 is more than enough for the Sophias power wise. Sophias are much easier to drive than my B&W N803 and the X250.5 absolutely handles the N803s without any hint of running out of juice. I listen to music on loud levels. The Pass amp is effortless, clean, zero strain and keeps great separation of instruments at high levels. Be it rock, jazz or the large scale orchestral.
I do agree though that a tube preamp is a good idea with Wilsons if the amp is solid state.
Good Luck
Hi I know it sounds like a little over kill however I run my Sophias with a krell 700cx am thinking of having them upgraded to the Sophia II's. I had the amp already before I bought speakers just didn't feel like selling just to get something else was running B&W's with it before.
