Ah I see. What an awesome amp the BHA-1 is!
There is definitely a difference in noise between the balanced / SE.
When I was using SE input, at max volume, I was hearing some static noise (little, but still some). Using XLRs, it was dead silent at max volume!
Enough of the BHA-1 in the M-DAC thread though..
Coming from HRT MusicStreamer II+, the M-DAC seems to be an amazing improvement though it is difficult to tell just how much because I got both the BHA-1 / M-DAC nearly at the same time.
Actually I'm really enjoying your BHA-1 and M-DAC comments as I am thinking about getting that combination myself!
Tell us more, please!
