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!

Look at the post right above yours! Krell seems to be the answer--except, according to posts below yours, Krell is going out of business. Good luck
please go to the montana audio site and check out there amps before you make any decision. they will give you a tube sound with solid state slam and detail. just go look and find a place to listen you will be impressed i promise
