@hilde45I agree with your comment. My brother is a classically trained opera singer (since retired) and he never owned any audio systems that would be considered audiophile quality. He systems were always the most basic that were available. He always told me that reproduced music never came close to the real thing. I don’t have the years of stage experience that he had nor the formal training, but I will admit my home system doesn’t replicate the sound that I found myself immersed in while performing on stage. I am not trying to replicate that level of immersion at home (since I think it’s impossible), but I do consider my system successful if I can see the sound.
At some odds with your very valid point is that there are musicians who often don’t have very good systems or care very much about sound quality in audio systems. That may merely be because they just don’t care about audio quality sound -- which would be weird -- or that they listen in some other way. But the notion that if one is a musician they already know how to listen as an audiophile is contradicted in a lot of cases, and that presents a puzzle.
Thanks!
