Did anyone experience Audio Prism's Ground Control

I have tried to find out some info on these items to no avail. Does anyone know where I can demo these?

Ozzy, Music Direct has them. $99 pair for spades.

I think they were more like $170 for the pair

I tried really hard to get a Demo set from the Manufacture but best he would say is to buy one from a Mail Order site and if it didn’t do anything try to get a refund.
Seems no real dealers carry it.
Probably a piece of junk if the manufacturer is so paranoid.

Hi Ozzy,

Sorry you couldn't score any samples, we don't have any to provide. You will have no trouble with a return from Music Direct, I guarantee it. These are not junk, however, if you have poured ground planes in all of your equipment in the amplification chain, or you have a fully differential amplifier, without direct reference to true ground, they will not provide you with any benefit. Otherwise what Deebill reported is what you will get.
