Power Cords: Signal vs. Shunyata

I went from the Signal HC on a Jolida JD-100A to a Michael Wolff Carbon Source. Back and forth, my wife and I listened. They were not remotely close. With the Signal cable on the player, the soundstage collapsed, and the music sounded flat & constricted. Without telling my wife which cord was which, she mixed up the two every time, thinking that the one that deadened the music had to be the Wolff, because we had received it only an hour earlier. The Signal is a terrific product for $59, but it killed none of the giants I placed against it. Too bad, because I'd have liked to save the money. And Frank at Signal is one of the true gentleman in this business.
