I have the same issue with my P25 and I have found that Radio Shack Anti-Static spray works. I does require re-treatment occasionally. Make sure to let it dry before you use the mat again. Sorry it doesn't tighten the bass or make any sound improvements. But it does take to worry out of having the mat drop and spin in to the cartridge.
Sick of static-y Rega felt mat
I have a P3 Rega, which I'm very pleased with, except that the stock felt mat is so static-y that removing a record from it quickly becomes a comical routine which involves me shaking the record to remove the mat or peeling it off. Basta! Can anyone recommend an alternative? Preferably cheap, preferably the same thickness as the Rega mat since I do not have a VTA. Thanks!
