I've heard wonderful things about the 4B-SST, but haven't had a chance to audition them in my own home. Brief listening with Joseph Audio speakers / Audible illusions tube preamp was impressive.
Have listened to the Classe stuff (used to sell it, actually)-- With Martin-Logans, B&W matrix and signature series products, Aerial 10T usually with krell CD and krell, classe or Audio Research preamps, I always thought the Classe CA-300 (which if I'm not mistaken is not much different than the 301) sounded a bit too laid back, and I agree with whomever said they doubted power ratings-- it's not that they lack control, their amps just never grabbed my attention with their dynamics. I'm sure they output rated power, you just wouldn't know it to listen to them.
The reason I don't really care for Classe much is why many like the amps, however. They are smoooooth, and I don't think you'll get a debate on that.
As for durability, in my experience selling Classe, and owning a very well-used and daily-flogged Bryston (college years- brutal on an amp), you can't go too far wrong with either brand.
