chakster,
"This is why the price tag is not the key to a perfect sound."
I don't think it ever has been anything more than an extremely lazy way of thinking.
No amount of industry encouragement to spend can ever change that. Hi-fi shows are notorious for demonstrating that. The data from blind listening tests suggests the same.
Even in the case of turntables where good engineering does not tend to come cheap, cost is not always a good indicator of performance.
Michael Fremer (Analog Planet) put up his Continuum Labs Caliburn ("that costs as much as a house" $200k+) against the then new Technics 1200G ($4k).
These videos can still be found on his Analog Planet YouTube channel.
