James,
A belated thanks for your input on my question about attenuation range of Bryston Pro amps. I spoke to Chris Russell as you suggested.
I'm now waiting to take delivery on a new 4B-SST SQ which I've ordered with a 0 to -30 dB attenuation range--and as an interim measure, I purchased some 10 dB Rothwell in-line attenuators for my 4B-ST. Eventually, I'll want to move the 4B-SST SQ to replace the 4B-ST and replace the 4B-SST SQ with a 3B-SST SQ, but...well, you know, the economy and all that, it'll be a while.
In any case, your help--and Chris's--is much appreciated.
Regards,
Joel.
