Anyone else in my shoes? Ears going.........

I just turned 63 and I think I'm going to have to settle for the gear I have with no more improvements. I don't think I can hear the differance any more.

I think I have a pretty good HT setup and a very nice analog rig (for what I can afford), but I think I've reached the point of diminishing returns as far as my aging ears go.

On the plus side, I really enjoy what I have, and my headphone amp and Sennheiser 650's really maximize what's left when I choose the headphoen option.
