Best of the Classe amp line??? 200/201 - 400/401?

For you Classe heads out there, I'm thinking seriously about integrating a Classe power amp into my system. I did audition a 201, but in another space. Without having to haul in a 301 and a 401, and being unable to listen to a 200, 300 or 400, is there one of these amps whichs stands out with respect to being sweet tubey sounding without the masking of the highs, or does the line have pretty much the same sonic quality in each of the price levels? Yes, I know my results may vary, but more information is better than less.

My other current contenders are a Jeff Rowland Model 10 or a McCormack DNA 2.

Right now:

Audio Innovations L2 tube pre
Adcom GCD 750 CDP
Von Schweikert VR4/5s

Thx!
