I used the herbies black hole and then millennium carbon fiber. I never play a cd anymore without the carbon fiber mat, worth the $ Herbies was an improvement, and the carbon fiber another step up
CD Mats -- do they work? Are they dangerous?
I'm curious about these. There's a new carbon fiber one that looks interesting (carbon fiber of course having every magical property known to man, and a few we don't even know about yet). Any thoughts on whether or not we should all be using these, whether their snake oil, and how safe it is to use them in our high end CD players and transports?
