That's what I assumed—and continue to assume: that the BDP-3 outputs on BNC, XLR and USB simultaneously.
My further assumption has been that the least likely explanation is a defect in the BDP-3 I purchased. Not impossible, of course, but I've had many Bryston components since I got my first 4B amp 30 years ago, and none has ever malfunctioned.
If that second assumption is correct, then there's some software setting that I have failed to implement that is preventing the BPD-3 from having all three types of digital outputs active at the same time.
Problem is I can't figure out, from the BDP-3 manual or the Manic Moose manual, what software adjustment has to be made to achieve that.
