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!
