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.I think that the answer lies in the fact that these musicians, as well as other music lovers, can truly enjoy the artists and music on whatever audio gear they are listening to regardless of the price. The music is the message, it is delivered regardless of the price of the equipment.
The reality check is that if music was not that enjoyable on inexpensive equipment, the music industry as we know it today would not exist. What percent of persons who love and listen to music and really are the mainstream support of artists have actually spent more than, taking a guess, $2K or $3K for their stereo systems if that, 2 percent, 3 percent?
I think inherent in the mindset of many audiophiles is that their enjoyment on expensive equipment is more than the non audioplile’s enjoyment on their relatively inexpensive equipment. I understand how you can think that, but I can say I know people who listen on "regular" equipment who love their sounds.
