It doesn’t get much more pretentious than this. Insinuating the people that choose to buy less expensive, higher value gear can’t hear the differences is ridiculous.You are right...
And no one need to pay to buy acoustic or psychoacoustic law.... they cost nothing to apply and make a difference bigger than ANY upgrade...
Relating price and S.Q. exceeding a certain boundary quality is no more possible....And this boundary is way more low than what most audiophiles think....
