Suggestions please: Upgrade from Krell KMA 160s


I would like help in finding an amplifier to drive Wilson WATT/Puppy 7's in a big room, with the following:
(1) Price under $8-10K
(2) Balanced inputs
(3) SS or Tube - doesn't matter
(4) Warm side of neutral - Krells too lean for me
(5) Soundstaging and musicality more important than Bass strength-
I'm looking at Classe (Dealer locally), Pass, BAT, Parasound Halo JC1 or any Tube amps that I'm not really familiar with but must have balanced inputs.
The Parasound would fit the bill but getting bad press for reliability/service/uniformity of production (in A'gon forums. Is Pass X350 really "lean"/thin side of neutral? They and Classe CAM 350s seem to get the best reviews........any Tube amps fit the bill?

I really appreciate any input/help.
Rest of system is Mark Levinson Ref 32 preamp, Esoteric DV-50, XLO Limited/Ridge Street Poiema!, Dominus interconnects
Thanks

Help!! A very honest Wolcott dealer told me he sold one set of P-220's to a Wilson owner (larger than 7) and it wasnt a good match. (I really respect this dealer's honesty) so am trying to get more input on Wolcott/WWP 7 combination.
Any other Tube amps with balanced inputs that can drive Wilson Watt Puppies in a really big room?
The bottle of great Cab that I threatened to give to Nrchy may have to go to someone else,:) although I really like what I read about Wolcott!
Any word/impressions on Atma-sphere?
Thanks again.
I am so far down to VTL-450, Atma-sphere and Wolcott but need someone to tell me how they sound with WATT/Puppies - I think I want Tubes but must have balnced inputs
