One man’s unknown artist is another’s very well known one. Audiogon members are unusually aware of cult-level artists, unheard of by the great unwashed.
But I must take issue with your opening premise @mitchagain, that audiophile’s "are the ones with their priorities straight". I was a music lover long before an audiophile, and my hi-fi is nothing more than a conduit to the music I love. Excellent sound is nice, but the music comes first. A fair percentage of my favorite music is of marginal sound quality; I’m not going to not listen to it because of that.
"Audiophiles are more selective in their musical purchases"? Because their systems are better than non-audiophiles, they are more selective? In terms of sound quality, sure. But I know a lot of non-audiophiles whose musical tastes are at least as "selective" as that of many audiophiles, if not more so. Ah, the audiophile bubble!
