I have never bought anything from the Cable Co., But I have gotten some great deals on Zu interconnects and speaker cables on eBay. None of them made HUGE improvements over the Audioquest ICs they replaced or could best a pair of WireWorld Oasis 7's. Once you get above a certain relatively low price point the law of diminishing returns seems to follow an exponential curve for me. But I only paid what I was willing to gamble and loose for them and I'd do that again, especially for speaker cables. The big fat Zu Libtec cables in single runs were an improvement over the Auvui Delux 14g silverclad cable I had in a bi-wire set up; but I would have been really disappointed if I'd paid list price.
I didn't start thinking about spending much money on cable upgrades until I'd upgraded my Rotel 100 receiver (an oldie, but goody) For a Primare I32. I know there is supposed to be a synergy between Rotel and B&W, since they share ownership; but the Rotel sounded very capable with my Canton Ergo speakers.
Long story short: I'd look at other things before I spent on cables, were I you.
