The answer, Scottht, is YES. I did blind tests on my Jolida JD-100A with three different PC's, and all three people listening agreed that while one of the cords was more open than another, a third (a Michael Wolff carbon PC) made everything sound live and three-dimensional. In fact, my wife guessed that the most lifeless of the three must be the Wolff, because we had just received it, and she figured that "it must need breaking in." She was quite surprised to find out that it was in fact only two hours old. Now three weeks later, it sounds better yet.
I will say that after hundreds of hours recording and producing music, I have a pretty trained ear for slight variations in sound. And yet, the differences with the Wolff cord were not marginal. It was dramatically better than the others. I have affiliation with Michael Wolff, other than as a grateful audiophile whose expectations for his audio system were expanded by his products.
