There is a thin line between snake oil products and scams, and I think the difference is in the marketing, which is imo on the scam side here.
They promise this cable will improve your computer audio performance. Not "you will percieve a difference", which hints to psychoacoustics, so the latter statement is indeed true. They can't get out of it by saying 'you can't measure the difference, you can only hear it', because they have to prove their point of marketing, not the other way around. I don't care what millionaires do with their money, but this kind of marketing really scams money out of the average consumer and it's disgusting. I remember when I was 15 and had bought my first own sound system, that I was thinking about buying a 150€ power cable because it promised to make everything so much better. The speakers were just a little more than that and I couldn't afford much else, so I'm glad I knew electronics a bit already and was too skeptic to buy it, even though it had so many 5 star ratings backing up their claims.
I'm sorry for everyone who spent more than a tenth of their budget on cabling. Unless you need extremely long cable runs, where the price of copper alone justifies it, but that's an edge case I guess.
