Sean - good tip. Will look into that. Still haven't heard a good reason for why ceramic is better, though. If the principle is to isolate the cables from the static electricity generated by the carpet and ceramic is good because it's a good insulator...then vibrapods or any "suspender" made of a non-conductive,polymeric material ought to be just as good. My guess would be that ceramic is used instead of rubber or other non-conductive polymers in industrial power application because it is more durable/resist atmospheric elements better. Then again, I'm not an electric engineer. Still..worth doing a bit more research on this. I'll report my findings back in a day or two...
