I think you have it wrong, pmb. I didn't see any scientific evidence from chess, only a proclamation that he is a scientist and therefore his opinions are facts. I don't think you'd accept that as science.
I'm not offering up my methodology as scientific testing, I thought that was pretty clear.
Maybe there has been rigorous, well designed experimental testing of these propositions - I don't know about it. When it comes to opinions, I'll take mine until the contrary is proved to my satisfaction. After all, what audio is about for me, is my satisfaction, although I do get a kick out of sharing.
