Yeah, but they sound like they know what they are talking about. After all, it is the cable engineers who provide technical information such as shown in the links. If the higher end cables make absolutely no difference these cable companies would not exist, or at least drop the cable side of the market altogether. They make these cables because they make difference in sound.
Have you read their information? They are making the claim that most audiophile power cables do not work only theirs will work. Their technology is based on a high tech pigmentation (paint?).
They also have a page on their cable designer. Just try to find out what technical achievement has he obtained? What technical degree does he have? At least, he got a very nice smile.
Based on their website info, you should save your $100 and wait until you can afford their cable. Because only theirs will work.
One other question you should also ask is. If measurement is not used, on what basis do these people grade their cable? Do they have a guy that sit around and go; "Hmm, this is grade A I will charge $1,150, and this is barely grade B we'll take only $500 for this?" And what exactly are the difference between grades? More bass? Nah, that can be measured. Less noise? Hmm, that can be measured too.
Curious mind want to know. BTW, Furutech has a cable demagnetizer that you might want to try instead. As a bonus, this device will also demag your CD and LP too. And it's a bargain at $1,800.
