All of these super-expensive cables are a scam. This cable wouldn't sound any better than a coat hanger.
BTW it's the same with those Monster HDMI cables, never buy one of those $100 cables Best Buy tries to sell you. It's a digital signal so it doesn't matter what type of cable it does through, as long as it gets there, so pretty much any cheap HDMI cable will do. You will not get a "better picture" or "clearer sound" by using overpriced cables. Anyone who buys this is both rich and stupid.
