I think it applies to just about every hobby, music, cameras,musical instruments, etc the list goes on and on. But we all do it in slightly different ways. Some do it all the time, in constant striving for that elusive sound they are looking for, some get new equipment and are satisfied for awhile, content to just enjoy what they have until some outside force or opinion affect there choices, and I'm sure there are other ways as well. All are OK, we all do things differently.
I wonder though are we ever really satisfied ?
The one thing I don't think most really consider is our actual hearing itself. While we are chasing that certain sound, our actual hearing is slowly but certainly going downhill.
So as has been said, just enjoy the music.
Great thread BTW.
