Did anyone experience Audio Prism's Ground Control


Fellow Audiogoner's

I wonder if anyone has any input on Ground Control spade versions? I am curious about the impact of these pigtails on your system's overall sound?

I also have their quiteline filter (4pack) installed in my HT room and they have helped lower the overall noise floor.

Ozzy, Earl was referring to the non-cryo version being
warmer. The cryo process increases transparency while
usually decreasing mid bass warmth.

About the Powercell,
Ted Denny himself recommends unplugging the Powercell for
about 30 minutes every 3 to 4 weeks. This phenomenon of
a diminished sound stage and strident highs has been observed by a lot of folks on the SR tesla thread. When ever I know I will not be listening to my system for a good three days I will go ahead and reset the Powercell.

I am trying a similar scenario with the reference GC.
I had a listening session today where the reference GC was taken out last night, but the regular GC rca was left on my Dac. After re-inserting the reference GC rca today, the sound stage underwent a vast expansion after about 5 to 10 minutes while maintaining sweet extended highs. Even with
this inconvenience, it is still a keeper for me.

I would love to compare the Walkers, and they will let you
demo them at the cableco. However, I have way too many tweaks and variables on the table at this point.

Oddeophile, I would also like to know which version you compared to your walkers.
I am using the walkers (two) on each speaker. One for the bass, one for the mids/high posts and one for the center channel. Using Ref and standard GC on the BD player output with superb results.

The Detail Magnifiers I have seen with the higher grade parts are still nowhere near the level of the walker reference + components, construction or triple cryo process.

Best,

Odd
Already having Reference GC’s on my speakers, I purchased a second pair of Reference GC’s terminated with RCA’s to try them on my amp (I run XLR IC’s leaving the RCA inputs open). When I didn’t notice much improvement with the GC’s on the amp, I moved one of the GC’s to an RCA input on my JL Audio F112 subwoofer. When I initially set up my sub, I painstakingly followed Jim Smith’s advice (Better Sound), and that worked pretty well. I found however that taking just 2 seconds to install the GC on my sub was the preverbal icing on the cake that pulled everything together. These GC’s are pretty amazing.
Raks,
Take the other RCA and plug it into your preamp input or output jacks if possible. Then, if your CD player has an additional analog output, try it in that position. If you are using an outboard DAC you will be surprised at how the CD player sounds with an RCA GC installed, compared to the DAC.

Bud, I just removed the RCA Ground Controls from my system and the bass and overall sound quality seemed to improve.
I still kept the spade Ground Controls at the speaker and Amp ends.

Is it possible that I had too much of the Ground Control?
Or perhaps there is a need to remove them for a period of time every so often?
