Pick a topic...build quality, bass control, overall sonic superiority to it's predecessors, and don't forget Bryston's 20 year Warranty that contributes to their great re-sale value...that's of course if you ever wanted to part with it.

None, period.

Please note this a review of the 6B ST, not the SST. The units are essentially identical except for a slight difference in their poer supplies. Also the 6B ST is (conservatively) rated at 250w X 3 channels versus the 6B SST which specs out at 300w X 3. The test sheet on my 6B ST shows the units pushing slightly over 300 watts in each channel, at least 20% more than it's published specs, standard for Bryston products.
I purchased this beast (85 lbs) to replace my 18 year old 4B and 3B (the 3B was bridged for my center channel) after I purchsed a pair of 7B SST's which literally blew my mind in their sonic performance and power.
Although I can go on and on about how far Bryston has come in 18 years with their producs, I didn't have any complaints about my older Brystons, I was just in the mood to upgrade after getting the 7's.
Well, the differences are astounding. I thought I had great performance with my older amps, but the 6B ST simply takes everything to a new level...bass performance is tighter and more controlled but still strong, mids incl. vocals are present and not "in your face" like the older amps and the highs are silky smooth.
I have played this amp through half a dozen speakers, old and new (JBL L series, ESS AMT, Infinity, B&W, Celestion) and they all sound better/smoother than they ever did before, no question.

Customer Service

From past experience with the 3B, Customer Service is the best in the industry as far as I'm concerned.
