Why would I deny or discount what I clearly hear, just because it doesn’t fit into someone else’s worldview? I don't need a blind test to prove to myself what I hear.
If I hear that one cable sounds better than another in my system, and post about it here, it is directed towards those who accept the possibility that there is a difference. I am not trying to prove anything to, convert, or convince those who don’t hear any differences and/or deny they are possible. Why argue with someone who has a firmly established contrary opinion? I am sharing my experience and saying that, if you are interested and open, you might want to look into it further, and maybe try it for yourself. Why can’t those who disagree respect that? Why must you rudely and repeatedly chime in and express your unsolicited opinion, which is likely already well known? If I see a post or thread of yours that I disagree with, but I don’t have anything relevant or useful to say, I move on.
