Did anyone experience Audio Prism's Ground Control

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.

Ozzy, great. Thanks! I would say one crisis at a time (i.e. on GC on one thing at a time for the great experiment). My speakers GC's are supposed to arrive tonight so this may be interesting. I wish they had come on Friday so I could have really played with them on Sat. night with the HT going gangbusters, but tonight should give me some ideas. Thanks so much for your kind support.

I would be most curious about a GC on a JL 113. Having two would be interesting. I have also read time and again using RCA GC's on front end equipment using one of each is the way to go (ref and standard). I just hope these don't squash the sound stage. In talking to some folks with a system similar to mine they did not experience the squashed soundstage with the ref series on the speakers. crossing my fingers...

Best,

Odd

Ozzy, got the ref banana's yesterday. These are a mother to install... tight as heck. But, after 2 hours of burn in they seem to definitely improve the soundield and as of my initial review so far do not seem to limit sound field or dynamics. But, this is preliminary at this point. I will do a full on test on Friday night when I have time to spend with full blu-ray hi def, etc. However, I did note cleaner, more detailed mids and high end in the short time I spent with them last night, and on a movie I watched on USA channel - Shoot 'Em Up, a fun flick for disbelief, but a blast to watch (I caught the tail end), I was surprised by the additional, what seemed to me to be, presence in the soundtrack even on compressed cable HD feed for Dolby Digital. The end title hard metal soundtrack came through with much more shear balls than the last time I watched this on the same channel a week or two ago, and had more instrumental separation. Suprised me. Then, I had to hit the hay for today's early start into the office.

Question on the LCD - have you tried both at the same time?

Thanks, Ozzy.

Best,

Odd
