It depends on what you are looking for in sound. Krell will kick yer booty, but I find them to be TOOO in your face. Great for rock and roll. Hey these are just my opinions, folks. The Bryston is "warmer" and I would think a much better match up for your tube preamp and M-3si's. I am a fan of Bryston, so I may be a little "prejudiced" and I know that we NEVER have THAT around here, do we :)
Do I own any? no, so I am NOT promoting what I have, just what I would choose over those two. We had Krell in the chain for about 2 days once. I am NOT Krell bashing, just doesn't match up with what my ears want. It's a personal taste thing.
(currently have Rowland Model 1's-matched pair, Classe CA300 in the HT and a pair of Wolcott P220M Presence Mono Block Tube amps in the 2 CH)
