I have the PAD disc. I've found playing the demag portion to have a similar effect to cleaning cable terminations with Caig treatments, treble is brighter, crisper, this settles down after a day or two when things begin to sound better than previous to cleaning or demag. Not demaging or cleaning cables periodically tends to muffle, obscure, grunge up the sound over the long term, a very gradual thing you really don't notice until you clean and/or demag. You are hearing just the opposite with the Cardas disc, pretty bizarre.
