How good is your hearing ? And how do you know ?

I remembered this article, about high-school students having their cell phone ring at a high enough frequency so the adults can't hear it:

I think just the opposite of inna though regarding hearing quality vs. equipment quality.  As my hearing is going down, I'm wanting my equipment quality to compensate as much as possible for it.

Of course, the other problem is when you're young and can hear perfectly, you can't afford the better equipment, so I listened on "The Record Eater" turntable.

I run tidal through an old Sansui 1000a with diapason adamantes and it sounds pretty good. Many of my high end audiophiles love the warm full sound. Many can’t believe that a 55 yr old receiver can sound so good with modern digital technology. 

I am not against compensation if it works and if you know what you are doing.

As I age, its the loses that really hurt.  The loss of friends, of family, of bike riding 50 miles, of the ability to retain thought or using the word that I knew so well but can't recollect ... the loss of secure balance the loss of a successful day at work...  but the loss of acute hearing is a particularly hard loss.   I still know music, but the magic of the separation of instruments, depth perception, the cleanliness of a triangle is just not there.  Live today, for tomorrow is a different place.

Stringreen, great post, man.
