Unfortunately, you are not right. Digital cables do sound different. And, believe, for many years I was exactly like you - digital is digital and bit is bit. And, I had two cables Oyaide and Chord, both proper 75ohm COAX. and sound delivered by them is different. Couldn't believe until I Heard it by myself in my system. I just borów the Chord from my friend just to make a test whether it will make any change.
