"No one will argue the virtues of a good record clamp or weight. But, how much technology can one cram into a good record weight? There is nothing on earth that could justify the asking price. One could look up a local machinist and have him make you one that looked identical, send it to a plating shop for a real gold plating, and probably have it all done for under $300. So just because someone is wealthy enough to purchase such an item, doesn't make him any less foolish for buying into the hype.
Have you seen the plug strip that is not even a very good plug strip, supposedly cryogenically frozen, and sounds so amazing you'll throw out your power conditioner? For only $400! The very Definition of snake oil. "
But whether nor not its snake oil is not the issue that was raised by the OP. That's a completely different issue from whether audiophiles are gullible or not.
