Did anyone experience Audio Prism's Ground Control

Thanks for the advise Ozzy. I just ordered a pair.
Did you go with the cryoed or non-cryod?

I was getting close to trying out the Walkers, but
then I came across a great deal on the new Stillpoint
Ultra SS footers. I hear they are a significant upgrade
to the regular stillpoints with risers and inverse risers
which I have. Like the AP GC's the stillpoints are another
one of those rare tweaks that improve sound staging and detail
while paradoxically sweetening the highs with better timbre.
The Purest Audio Design digital filter is another that I am
now playing around with.

So, the price of the Detail Magnifiers is ideal for my Gallo
Nucleus HT speakers. For my DeVore Super 8's I will have to
wait and see if the Walkers reference HDL are that much better.

Scottmac62 , I did'nt go for the Cyro version of the Detail Magnifiers. Probably because it would have added about 4 weeks to the order. But, I would like to know if it does provide any sonic improvement.

Keep me posted on any difference when you try the Walkers.
I will also look into the your other tweaks.

I no longer see any benefit with the 9V battery idea. The Ground Controls are still wayyy much better. But at least I got to try it for myself.

Scottmac62, I have not unplugged my SR Powercell but I do periodically unplug my Preamp. My Preamp has no on or off switch so it is on 24/7. Sometimes it just seems like the Soundstage has gone flat. Unplugging the Preamp for a few minutes then plugging it back in seems to rest it. I might try unplugging my Powercell, thanks for that tip.

I think you meant to type that the Cyro version is warmer?
My system leans toward the warmer side already. The Detail Magnifiers seem to bring out the bass quality quite nicely.

I don’t know if we will ever hear a fair comparison between the Walkers and the Detail Magnifiers. Because when big $$$ are spent on the Walkers I doubt if anyone would say the Detail Magnifiers are as good or better.

Perhaps if the Walkers had a trial period, I would try them myself.

Getting back to the Ground Controls. It seems the latest buzz is connecting a 9 Volt battery to its negative side only and then attaching that to the negative posts of either spades or RCA.
I have tried it in several places and though it seems to be ok in places I do not have the Ground Controls, they do not add to the Ground Controls enhancement.

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.
