I have two 28B SST3 (cubed) amplifiers. The input sensitivity is so great that most preamps (including mine) can't use but about a third of their volume range. I have heard that Bryston didn't put in a switch to lower the sensitivity because it would have compromised the sound. Is that true? Has Bryston solved this problem by now? Any information will be appreciated.
Thanks.

HI Simm
That is correct the safety certification would not allow for a switch on this powerful an amplifier. The gain in the amp is 28dB which is average for most amplifiers.
I do not know what preamp you have but I would ask the manufacturer if you can lower the gain in the preamplifier.

Hi James
Curious ..........Were some 28 Cubed amps set at 28db and some at 29?
-
They are all at 28

I was confused because you said they there were set at 29 when I asked, when I couldn't find the gain switch that doesn't exist on the 28's.

No there is not a gain switch on the 28B
