Did anyone experience Audio Prism's Ground Control

Just an update.
I have found that using a Reference RCA along with a standard RCA on my Cary 306 Pro CD player provides the best of both of the RCA qualities.
That is, large deep soundstage and precise highly detailed imaging.
In addition to those two RCA ground controls I now have one on my Oppo BP-83SE, one on my LCD and one on my Squeezebox Touch.

Note:
I removed the RCA ground controls from my Preamp and Amp; there they provided little if any value.

I also have the 2 sets of spades of standard ground controls on my Andra 2 Speakers along with a set on my Amp.

On my Home theater speakers, (B&W) I have a couple of sets of the standard spades. Soon to aquire a few more to complete that system.

Bud, I still say you are a Genius!

Ozzy, which version of the GC on the LCD did you use and what were your observations of adding it? I just ordered a full complement of the reference GC's for my speakers to begin checking out the benefits. I ordered the banana versions as my spades are rather large to begin with and I dislike stacking spades on speaker terminals.

Has anyone tried an RCA GC on their powered subwoofer(s)? I have two JL Audio Fathom F113's I would also wonder if adding them to would benefit in the bass arena?

Many thanks. Just beginning my foray into the GC world...

Oddeophile, I'm thinking that the Ground Control RCA's are best used on front end equipment.
Such as a CD Player,Squeezebox Touch, Blu Ray player and yes a LCD TV.
The TV is a tough one though. I have gone back and forth between the Ref and the standard RCA and still cant decide which is better. Right now I would say the ref. I have it plugged into one of the video composite inputs. But I suppose any input would suffice.
The improvement is a slightly sharper picture with more depth and deeper colors. And of course then the TV Audio is sent through my Multi channel Receiver where that is also improved.

I also own a JL 113 Sub but have never tried a GC on it.
Yet...

Ozzy,

I read you have 2 rca GC on your Cary cd player. I am running XLR wires , so I assume you only need 1 GC on the negative rca out jack. Would that be correct?

Can you tell me where you put the other rca GC on your Cary, beside the rca out and what degree of improvement you noticed using 2 GC rca versions on your Cary.

Thanks

Moonguy, I am using the RCA type Ground Controls on my Cary. The Cary has both Balanced and RCA's out. The balanced outputs are sent to my Preamp leaving the RCA's open to be used with the Ground Controls (left and right channel).
I found the Ref RCA to be highly detailed with a somewhat narrower soundstage than the standard RCA. So, using one standard and one Ref RCA provided the wider soundstage with more detail. If I were to use only one RCA on the Cary I would use the standard.
I also prefer the stanadard spades on my speakers.
