If I flip cables back and forth between bis and singles and cannot perceive a difference it is beyond good enough for me. This I
know. Not even a tiny reason to spend hours doing ABX listening tests to try to prove to myself that I am right. YMMV, which is cool too.
Are you saying that a real double-blind hasn't been done by someone on this issue?
Oh, are you interested in the Signal Cable bi-wires? Or are you just a provocateur?
