Did anyone experience Audio Prism's Ground Control

Still for $150 bucks plus shipping it still sounds like a "maybe/iffy" product.

Well did you also state this???

"How large is the effect of these devices? More than I hear from the Isoclean fuses but not as much as an interconnect or speaker cable upgrade. However, what the GC devices do may be unattainable from a cable upgrade. I have rarely, if ever heard this combination of virtues from a cable upgrade."

Ozzy - I think you probably excerpted the only sentence in my review where I lent credence to doubters. I think it is fair to say that most tweaks do not find universal acceptance in the marketplace. That is the basis behind my statement.

However, you should note that everyone who was exposed to A/B'ing them in my two systems, heard the improvement and liked it. Subsequent to the review, I brought them to another friend's high end system and he was also favorably impressed. So, my own experimentation with audiophile friends has been 100% positive.

The 6 Moons review didnt sound too positive to me. One reviewer ( below) saw no merit to it the other (below at bottom) thought it maybe made a improvement.

First Reviewer
"After 'breaking them in' for the equivalent of 40 hours or so, I experimented with the devices in three systems in three different venues; with three different speakers, two different preamps, two different amps, one integrated, one receiver and one CD player. Over a series of sighted A/B listening sessions, I sometimes reckoned that I heard a touch more body and low-level dynamics in the mids. But the differences weren’t tenacious enough to trust. In unsighted—not double-blind—A/Bs it became clear that I could not dependably identify when they were in or out. The same held true over periods of long-term listening. Since I was unable to reliably detect the possible differences in or out of the various contexts explored, I have to say that the Ground Control devices aren’t for me. Your mileage may vary."

Second Reviwer
"I will go so far as predicting that some audiophiles might not hear any improvements either due to their systems not revealing them or their lack of sensitivity to the particular sonic benefits the GC devices convey."

It is an extension and significant refinement of the exploration carried out under the title of Electron Pools.

Budp:

Is this the same thing you were refering to as 'Electron Pools' on other forums?

Just in case anyone was lurking and has not seen the 6 moons report, here is the link.

From what I have seen there will be a review in an up coming 6 Moons release. It has both sides of the story too, with someone who found little or no improvement just as involved as someone who found an improvement and liked it. This is the reason for the refund policy as we do not want anyone to feel they have been cheated.

Budp, Thanks for the response.
I've got to say the discription you have provided sounds a little like hocus pocus.
But, the tweaker that I am ,I would have loved to been able to try it and if it had merit I would have bought it.
But I am not going to try something this iffy for $150 plus shipping costs and then try to get a refund.

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.

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.

I think they were more like $170 for the pair

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

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

I have had them installed in my system for a few weeks now. Even with the clean power of a PS Audio Power Plant running my system, I could immediately notice a lower noise floor, with dynamic and clarity improvements.

I have become a firm believer that anything you can do to reduce noise in the system will reap musical rewards. I should also add that I have always liked AudioPrism's accessories and have owned an AudioPrism Debut II amp and Mantissa Preamp for years. The company offers real products, not smoke and mirrors. The Ground Controls are easy to install and immediately hear. Try them; I think you will like them!
