I have no idea why they work..double cryo'ing might be part of the reason, but at Eric Hiders I compared my Ridge Street Audio Poiema! cables to his Gregg Straley speaker cables and on Eric's system (Epiphony 21/20 speakers, Gary Dodd 150W amps, Bent pre plus Stan Warren Superphon III pre) the Straley speaker cable sounded better.
I know what they are made of, but have no idea why they sound as good as they do.
Correct on the website....That's the first time I've seen it, thanks for the link...I just bookmarked it
Eric has worked with Gregg for a long time and he wouldn't tell me much about the cable....and even if he did, I would have been sworn to secrecy

I will say, I think you should try the 20 day trial and then tell me what you think of them....
