Those are honest statements. I sure prefer that to the pie in the sky type hype that goes so often with such products. There is no doubt in my mind that such an experiment will vary from system to system.I think that I did not prefer the discs on power cords, but for some reason, when I drilled holes in the samples, and slipped them over incoming AC, that was the best change that I had heard. Now, I will say that I also cut a thick piece of copper sheet into a circle and sandwiched it between the two sample discs. It was then that I heard a definite increase in bass clarity and a little better treble. As I added two more sizable discs to the system, these effects were less, and as a matter of fact, I wasn’t at all sure that I cared for the combined effect. So I removed one disc from the system, leaving only a mini disc on the CD power cord. I did try the weak magnet on top of the disc, and found a more pleasing effect, but I will go no further with this experiment, as I feel my system could not possibly benefit any more by the addition of more discs.
