****"Why is it so darn difficult for some people to accept the simple fact that some listeners have better hearing ability than others; wether because of physiological differences, experience, or training? "
ITs not hard to accept that, but knowing who those people are for sure can be a challenge.****
Does it really matter who those people are? Seems to me that if we accept that simple reality, then one can go about the business of trying this cable (or whatever) or that cable to see if we can hear those differences; and if those differences constitute an IMPROVEMENT in our estimation. Bottom line: we accept that differences exist and if someone else wants to kid himself about a particular difference, who cares? The key is to keep an open mind about the possibilities. If we can't hear a difference we should just move on. We spend so much time disputing what someone else claims to hear. Why?
