Anyone who hasn't heard these cables, better not unless your committed to spending $$. They are NOT a gimmick! There is NOTHING that sounds as real, no B.S. I auditioned all the best balanced interconnects from the big names (Audioquest, Nordost, PAD, etc) at 3X and 4X the price and it wasn't even close. Facts are facts - if you trust your ears you'll never go back to solid copper or silver or gold . . . !! I wish i could afford the speaker cables, but the slurry (similar materials to that used in non-mercury thermometers) is expensive and more tubes are required for higher level signals and greater lengths - that's the only caveat!
