High End Audio and Your hearing as you get older

I just turned 58 and have had tinitus (ringing) problems caused by influenza for about 12 years. I listen to music everyday and have learned how to listen around that frequency which occurs about 9khz. I can still hear frequencies higher than that and everything else is "clear as a bell". To address the original question, I believe the better the system at producing TRUE sound the more we enjoy it regardless of age. If Mitch4t means lower quality sound when he asks if "midfi" will sound the same as "hifi" when you get older the answer has to be no. Ballen got it exactly right. My system produces sound that sounds right to me and that sound keeps me front and center everyday. One thing everyone might benefit from is equalizing the pressure in your ears as you begin to listen to music. I am talking about what you do to lessen the external pressure on the eardrum when you fly at high altitude on an airplane by pinching your nose and blowing gently. You will experience greatly increased treble and clarity after this adjustment. Listening on clear days with high barometric pressure push in on the eardrum and prevent hearing music at it's best so equalizing the pressure allows better hearing. Want to thank everyone for their posts on this issue. Great question Mitch4t.

Unsound, I do believe we hear things differently as our hearing diminishes. The balance of the sound would almost have to change some but, with our ears and brain being more sensitive to the midrange frequencies, it may not affect our hearing as much as we might think. The brain has an amazing ability to compensate for that sort of thing.

On a related note, I have often wondered if much of us older folks' appreciation for LPs is due to the fact that we can no longer hear as many of the crackles and pops that used to irritate us in our younger days.

Yes, your hearing range and depth does change for the worst, but each person is different. One of the pluses from listening over the years is that you train your ears to hear better, so it is some compensation for the fall off in range.
Audiologist will tell you that loss of hearing is part of the aging process, but with the advances in hearing aids you will be able to capture much of what your hearing loses.

Dhohnson54, thank you for your thoughtful response. I really don't know for sure whether or not what I suggested is true or not. I suspect that it might be akin to losing one's taste (or sensation thereof) of oil in a salad, without that counter balance the ratio of vinegar would seem to be too acidic.
Your point about "older folks appreciation for LPs" is worthy of consideration. The same might be true of analog tape hiss. I would also consider the thought that "older folks" have adapted to such surface noise and acquired the ability to hear past the surface noise long ago, due to necessity. Something that younger listeners might not have been required to adapt to.

I am 62 and have tinnitus and can still enjoy my system. I agree with Tpreaves, that I can critically listen better now than 30 years ago. That is a function of experience and experiencing many systems, say at audio shows.
I do believe part of that training is listening to multiple systems, to hear how different they sound and choosing the sound you like. For example, listening to Wilson speakers just leaves me cold, I do'nt get it. There is nothing wrong with them, but they represent the antithesis of the sound I like.
I would only add and not to alarm you oldsters, but hearing decline goes way below 10khz, I would say to 6Khz, with presbycusis. No reason at all you can'nt enjoy your music.
As an aside, I live in the UK and shops here, have begun using very high frequency noise generators 20Khz+, to drive away kids who are hanging around making a nuisance of themselves. It is said to sound like mosquitos. Are they in use in the US?
