I'm not against people making money, but what I dislike are crazy claims, high prices and no engineering justification for it.
I'm reminded of the ML HQD as a prime example of this. A $28000 speaker system in 1984 that measured poorly and sounded even worse according to Stereophile. However the designer made big claims and apparently tried to mislead the reviewer and was caught. Unfortunately this type of stuff goes on in the age where it is even easier to verify things.
Some equipment clearly justifies it cost from an engineering standpoint, exotic materials, superb manufacturing, etc. Of course all that money being spent doesn't necessarily mean you have a better product, it just meant you bought a more expensive product.
I could sell you a Camry for $25000 or I could put another label on it, coat it in gold, sell it for $100k and say it is a better car, but is it?
