I am having problems with BHA-1 volume control and sensitive headphones, even on low gain. I cannot run Beyerdynamic T5p.2 at all, I have to set the volume so low that it does not go beyond the point of channel imbalance and it is loud. T5p.2 are crazy sensitive but what about HD800S - cannot move the knob beyond 9:30, with HEKv2 and some classical tracks 11 is too loud.
I also used BHA-1 as a preamp to two bridged 2B LP amps. To set a BHA-1 volume to a 12 I had to set gain on both amps to roughly 50%. I am thinking about using in line attenuators between Bryston BDA-2 and BHA-1. 10dB balanced attenuators should do it, I think. I have Shure switched attenuators, tried -15dB but I am not sure how they affect the SQ. Or maybe iMatch is a better option.
Can anyone help please?
