There are actually two issues. The first is "do people want to know the truth" about sound quality and what it is, and the second is "if they are taught do they care?"I have pretty much found that the answer to the first is "not really" the mythology is more fun. And the answer to the second is, "well yes your right, but what I have is just fine". Sound qulaity, per se, is not a competitive advantage. It hardly even rates. Looks, size, prestige all seem to be more important.
Just my experience.
