What really does my head in is whenever someone is challenged on an opinion, even with evidence, there is a chance they will just default to either:
a.) Your hearing must not be as good as mine.
b.) Your equipment must not be as good as mine.
I recall a retailer in New Zealand that was notorious for this. They'd "review" (advertise) something they sold like an "audiophile network switch" for thousands of dollars on their YouTube channel that would make streaming music sound "dramatically" better, making the staging wider and the hi-hats sparkle and whatever. When people with an understanding of how network traffic works would chime in and go "hey that is fundamentally nonsense" the retailer would just shut them down with "you haven't heard it, so your opinion is irrelevant" which is a maddening argument because there's really no reasoning with that. Every product they sold was, of course, mind blowingly good. If only you were willing to pay, you too would experience this nirvana.
What I couldn't figure out was if the guy genuinely believed he had the elusive golden ears gift, or if he knew he was selling snake oil and just kept up the bullshit act for the customers. You would have to think all of these sellers and manufacturers are scammers, but if there are enough idiots buying snake oil, there must be some idiots selling it, right?
