Perhaps musicians listen about as well as we would performing.
?!
I wonder if you are thinking about some 19 yr old punk rocker screaming at a bar into a 300 dollar plastic PA kit.
I am not a professional musician (not my livelihood), but, I’ve been known to be strapped to a violin (piano to a lesser extent) since I was single digits old. Are you implying that the average "audiophile" I run into at shows could hear a violin better than me? In fact, I have a few different violins. I could play/record a few different pieces on 2 of them and I can safely say you wouldn’t be able to say which is which. To me, the difference is night and day (must be some kinda voodoo indeed).
I know my place... A friend of mine is a sax guy, who’s been tied to it longer than I have to my instrument. Do I hear it better than he? Absolutely not! Another friend of mine is a Ghanaian musician who only lives a couple of miles from me. I certainly ain’t no expert of him. His way off describing music would sound quite bizarre to some, but, he is also the most golden eared bat I’ve ever known.
When I’ve done blind tests with gear swaps, the "audiophiles" I’ve known have always failed by a mile. I could trick em all day long. 😁 The guys who reliably pass such tests are the musicians I know.
Strange thing is...You seem to be dismissing decades of dedication and pain one may through with an instrument...just like that. Well, frankly, I don’t give a crap..., but, sure, Okie dokie.
