Haven't heard them directly, but from what I've heard, it echoes Jkphoto's comments.
If you want to try a "charged dialectric" cable, I'd recommend Aural Thrills right here on Audiogon (userid billardhockey). His Force cable, available with Copper, Silver, or Gold Alloy wire, is most probably a lot better than the similar-priced AQ cable, and it sounds fantastic. I got the silver wire Force, then upgraded to the gold alloy.
The cable uses the chassis of the source and destination component; a third "ground" wire is attached to each. It isn't mandatory to connect it, but when I did, the music sprang from an absolutely quiet background; it was almost spooky when i first heard it !
Anyways, no affiliation with Aural Thrills, just a satisfied customer - about 10 times over !
My 2 cents.
