Recommendation for Digital Coax

Typically optical is of inferior quality. Generally known, I tried it a couple times and had to agree. I think it is the transducers that change from electrical to optical and back. I doubt any audio companies could make their own and probably are a commodity item not made as quality above cost.

DH Labs produce good quality, cost effective interconnects. I have used them off and on for more than  twenty years on various systems I have been creating.

If a manufacturer says the current should flow one particular direction. I am going to do it. There are so many variables in this pursuit… life is not long enough to wast time investigating things I don’t have to. I would prefer to listen to music.
