At 53 I just recently got into high end audio because of my damaged hearing and raging tinitus. I find that the finer equipment allows me to enjoy the spectrum that is left to me better. And I believe that there is evidence out there somewhere that ones hearing acuity does improve within the spectrum you have to work with, much like the nose of a perfumer gets better with training.
For me my ears are ringing when I get home Friday night, but if I wear ear protection mowing the lawn ect, Sunday mornings I can really enjoy my system.
PS, beware of silica based antacids can cause tinitus, its in the fine print if you check.
