Mass and vibration cancelling on top of CD player?

Rhyno I'm not sure what you mean by "wall plates" and AC "distribution boxes". I agree on the Equitech's grounding information.

look at products by oyaide & furutech that are simply wall mounting plates for an AC outlet (which also must be upgraded to an audiophile-grade duplex on a dedicated line, to do it right). and, if you have a power conditioner / distribution box, you must address vibrations of it, likely before worrying about the preamp IME.

Thanks Rhyno.10/4
