Rwwear, yours is just one side of the constant argument about hearing differences. I just compared two identical cables other than one using long linear crystal copper and the other silver, anyone who could not hear the improvement of the silver should invest very little into reproducing music. But my only dispute with those holding your position is why you care that I don't hold with your position. You cannot provide proof that there are no better or worse pcs. Please don't tell me of the same/different 30 sec. comparisons, they are invalid measures of what people hear.
