Krell, Rowland. Levinson, or Pass

I'm looking for a new solid state power amplifier. The amps I will be auditioning are: Krell (FPB 200c) Jeff Rowland (model 10) Mark Levinson (334 & 335) Pass Labs (X350) I know these amps all have different power ratings, my question is what is the "house sound" of these companies and which makes the most "musical" amplifier with the best soundstaging and imaging. Thanks in advance for your replies.
From the choices above I 'd go with X-350 from Mr.Pass which I think by far is the best amp under 10K....if you can go above ..check out Jeff Rowland 8TI.......enjoy it
Go for the Pass. I have a Pass Aleph 3, it's fantastic. His products are amazingly musical! They're not lacking in detail though and the X-series is very detailed from what I've read. However, his circuits are so simple that he keeps the emotion and purity of the music without adding any electronic harshness. Go for the Pass and smile...
