I found Bryston to be a little too flat in the mids and too bright in the treble for my taste, but I'm a tube lover so maybe I'm biased. No pun intended. I owned Classe for a number of years and was very happy with the sound. To me, the Classe amps sounded a little sweeter, more robust, warmer, but not too extreme. Classe is a good match for neutral to dry sounding speakers like my Thiel CS 1.5's.
I have since moved more toward the sweet musical sound of tubes with my Conrad-Johnson and Audio Research gear. I guess this doesn't answer your question but it's really a matter of personal taste and component matching. I lean more toward a slightly sweet, warm, and musically engaging sound. I prefer Classe over Bryston for SS gear and I even prefer Classe over Krell. I didn't like Krell at all. I found Krell to be powerful but dry and almost harsh.
