So let's assume someone can only hear between 250hz and 2kz. Still gonna tell me it doesnt matter? I mean no offense to you if you are not trolling just trying to elicit a reaction, but I truly do not understand how you do not understand this point.
No offense taken, and no, I am not trolling. I'm offering a different perspective which happens to be my own. I'm not saying that it doesn't matter that our hearing acuity is different from each other. I'm saying that is one of an infinite number of factors at play that might make you and the next person unique and different. I'm saying that another person's ability to hear and discriminate a way that music is reproduced by a system to their own personal liking does not hinge on any one thing, but a whole universe of of diverse factors. Pointing at one of those factors and judging that they are someone who should be ignored or listened to based on that single factor is ludicrous, IMHO (ie he's older than 60 so his opinion probably bears no relation to what a 30 year-old might prefer - in fact they may prefer exactly the same kinds of things). Take the example about the detective you liked that someone came up with (and I agree, it is a good metaphor for some of what is at play here). Make that detective a one-eye'd detective, or one who is otherwise visually impaired and may not see quite as sharply as the next person. I'd still posit that based on his/her experience (we'll assume he/she is a longtime veteran like Columbo - and Peter Falk actually does have a glass eye) he would see more at a crime scene than the average untrained and inexperienced person. Take my previous reference to my longtime audiophile friend who is deaf in one ear - I've listened to many various systems with him over the years, in many locations. I've listened to his comments on those systems and I will tell you for certain that he may not hear soundstage, but his ability to discriminate and facilitate improvements is top notch in my book. We also have somewhat similar, but not identical, musical tastes and I think that does help. So holding someones ability to hear above 15khz, 12khz, or whatever, does not seem like a given qualification for that person giving very valid and astute observations about the way a system sounds. In your example of someone whose hearing was severely impaired I just don't have enough experience with that to comment, other than there are speakers that I've heard with very limited range that are profoundly enjoyable. I suppose I would weigh severe hearing impairment in if it was something I knew about them, just as I might weigh in their preferences in music, sure. As far as the example of the dealers pushing some wire that Douglas mentioned in his post - one could as easily assert that they had an agenda in selling the wires they represented, over other possible choices as well as the one Douglas already owned (which meant no sale to them). Indeed they also could have had hearing impairments and tastes that do not match Douglas's tastes, and also could have been praising the wires based on their use in a different system. I don't know. I'm not sure why one would jump to the conclusion that they had hearing impairment and that was the cause of their preferring the wires they did. Again, so many things at play and all of that is just speculation and really does mean nothing. Ultimately what counts is what you enjoy yourself - I don't think one can elicit a formula for screening reliable candidates to provide you with those answers. The best candidate is you.
