Okay, out of curiosity I dug out a pair of freebie RCAs and connected them and a pair of Blue Jeans cables to my DAC with a splitter, and used the input selector on my amp for a spontaneous test. No blindfolds or anything, the cables were in plain sight. And yet...I couldn't hear a difference.
I find rapid switching to be really useful as well, I use a passive switch box it gives you a good idea if there are any obvious differences such as level differences between CD players
Ever made a fool of yourself and you just wish you could go back in time?
...so yeah.
Too many times to mention
Humbling realization aside, I'd like to apologize if I offended anybody. I was in a pretty foul mood earlier, but that's no excuse to be obnoxious. And, no, I don't believe in cable burn-in.
No offense taken
