Only a technically advan-ced maker could make it available to the public.
I don't know how advan-ced they are in cable making but, they should consider a more sophisticated way to sell them. The ad copy reads like an ebay ad.... Kind of has the essence of snake oil. Whether their cable theory works or not, who knows? At $900/pop they should have the profits to hire an ad agency.
Since their site won't sell it to anyone who would actually buy it, maybe someone who hears it in person one day could comment on it. And, maybe they could measure this 0 inductance cable and see what other measurements come at the cost of its design... like high capacitance.
