I have had both the 4B-ST and the 4B-SST in the same system and preferred the SST. It was smoother on highs and middle and retained the solid bottom end Bryston is known for.
I could be wrong but I think as far as the 6B's go the ST is nearly identical to the SST. It was designed just before the new names and corresponding faceplates. Though it would be better to check with Bryston directly.
You will get better separation with the monos and clearly more power. Though I digress, depending on your taste and associated equipment your mileage may very with each unit listed. Personally the 4B-SST was enough.....for now.
