IMO, when some people trash-talk gear they haven't heard it's because the price is more than they could afford. So it's automatically "over priced" or "not worth it" or "product X costs half as much!" because they are jealous. They can't afford it, they wish they could, so it's not worth the price and those who CAN afford it are fools for wasting their money. It's one of the sillier things that happens on audio forums. If you can't afford something, there is nothing wrong with that and it's no reason to snipe at those who can. I can't afford to buy Burmester amps. But I'd love to try them and I don't slag those who can, I admire them.
IMO, only incredibly vain and conceited people categorically discount criticism as mere jealousy.
