Very interesting about USB sounding different with multiple outputs into the dac. I have the same AES and USB cable and my conclusions are there same as his. The AES is more full bodied and relaxed. The USB on my lumin sounds thinner and definitely takes the upper mid and tweeter on. The lumin rep that’s all over the forums has said time and time again AES usually sounds better. This is where I love Bryston no good better best though this is somewhat different they can stand behind it, Bryston’s USB output is superior over models many times the price. Good read, thanks
