I was also there in rec.audio.high-end and @ted_denney is absolutely right. That’s why I don’t waste time in any of A'gon's "makes no difference/yes it does/no it doesn’t/show me the blind test" debates.
It’s not that users never change their minds, but that only happens to those who take the time to truly listen and put their biases behind. I think many of us started out as cynics. Some get stuck there.
