Everyone has made valid points. It seems as if a perfect storm has formed and there is enough blame to go around as to the cause. Greed and hubris are the main culprits. And this applies to the customers and the sellers /makers.
I would add this.
Is it possible that the MANUFACTURERS of high-end audio, do not want their products to be TOO readily available? High price and scarcity, equals exclusivity. And exclusivity is important in most high-end products. It seems to me that if the high-end snob brands wanted to expose their wares to the masses, and possibly gain customers, and make it more convenient for their high end base customers, their stuff would be sold in Best Buy. Or Crutchfield. etc... Or, ALL brands would be available at the same stores. Either way, there is a lot the makers could do to solve the problem. Unless they think a Wilson Maxx might contract some working class disease from sitting next to Polk or, god forbid, york! But given the profit margin they get on each item, they are doing just fine. It's your responsiblitiy to seek them out.
Cheers
