Skilled artists / machinist can train body to stupid degrees of precision, i.e. identifying colours, feeling out a thou. IMO something like that happening with audiophiles who are skilled at listening but when brain trained to discern fine details forced to rationalize inputs whose differences are largely chaotic and start hallucinating noise into conviction. I think many audiophiles are actually hearing differences, but the source of differences are subjective/meaningless.
