I assume you were questioning my comment about "reasonable to doubt".
My point isn't that you presume they are liars or fools and must be wrong. It is that when someone states something that is contrary to your own experience it is reasonable to wonder if they are mistaken. This not the same as taking for granted they are wrong. People do make mistakes.
I was questioning the assumption that RF might be responsible for the reported hearing of differences. 40% of those that have responded to this poll are hearing differences (or think they could). Does this square with the likely proportion that are having genuine RF mains problems? It would seem reasonable to assume that the reason such a large number of audiophiles are hearing differences between mains cables must lie elsewhere.
