As with most of the high end cables, these are priced at about 10 times what they should cost based on manufacturing costs. Of course, the way things have gotten in the industry, to be considered as really high end they have to be really high priced. Optical cable costs pennies per foot. And if you all are willing to pay $400 for a battery power supply then I'm really in the wrong line of work.
Breaking the ground should be a good thing and these cables may actually make a useful difference. However, any time I ask the question "what other system upgrades are available at this price" then expensive cabling always comes up short. You'd have to spend a minimum $5000 to wire your system with this stuff. More if you have a more complex setup. For that kind of money I can think of a lot of component upgrades or system changes (bi-amping or acoustic treatments for example)that would be within my reach and have the potential to make more of a difference.
Sadly, none of what I say will deter any customers. Might as well pick up those $30,000 speaker cables while you're at it. Gotta have 'em to impress your friends.
Quick, somebody find a way to reverse engineer this product so that we can DIY it for $50 or less. That would get my attention. The world is full of over priced cables. The only reason cable companies are coming out of the woodwork, so to speak, is that the profit margins are insane.
