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.

The biggest difference is in the slight details. The DM's are about on par with the older Walker Mk II HDL version in total improvement from what I have been able to determine. The reference + would add maybe 5% improvement. If you are into the last word in improvement then the Walker Ref + is the deal. They are triple cryo'ed at each stage and use a proprietary RC network with all silver parts. the DM uses much lower quality parts in comparison. All Walker parts are also nude components. This all adds to a next level degree of improvement. The difference would be in the subtleties of the presentation.

It is indeed interesting to hear what the CG's do with each system. I have yet to experience the soundstage shrinkage others have with the ref GC on source components. Using both together works in a synergisic approach in mine. Interesting. Using them in tandem on my ref BD player was really amazing and seemed to take the video as well to the next level of HD picture. A tad more detail and depth/dimensionality to the picture. Sweet.

Not everyone is interested in squeezing the last bit of difference i their system. DM's would work well for 95% of audiophiles in conjunction with everything else. I am not saying anything negative they are anything less than revelatory to anyone nor am I attempting to knock them, at all. Everyone has their own cup of tea they like, right? I was interested in the last word I could achieve in my system so the difference was worth it. I did not have positive sonic impressions with earlier versions of the caps they use in the MD so that kind of turned me off to the idea. Earlier versions of those caps sounded muffled in my system, so when I saw that it wasn't as much a possible component to me. The all proprietary silver nude caps used in the Walkers were the last word. At least, until they come up with the Reference plus, plus. Ha, ha.
Oddeophile, thanks for your comments. You do know that there is a newer version of the Detail magnifiers and they also are said to use higher grade silver parts ?
Is that the version you compared to the Walkers?

On your Blu Ray player, are you saying that you are using the Ref GC's with the Walkers how is that possible?
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,

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.
