I'm looking for some technical help. I am changing my system to a bi-amp one and want to add an additional Bryston amp. I have been using a 14B SST and am thinking of adding either a 4B SST or 3B SST (and then maybe swapping out the 14B for a 4B). I think the 3B would be enough, BUT.... I have a question on the specs for these amps.
Looking at the 1 volt inputs, both amps show 29 dB gain. However, the 4B (and most of the line) show sensitivity of 2.3V, while the 3B shows sensitivity of 1.3V. My brain seems to have a block -- I haven't so far grasped that two amps can have the same gain while one has higher sensitivity. Maybe it's just that I'm not understanding what "sensitivity" means in this context? Help, please!
