Did anyone experience Audio Prism's Ground Control

Ozzy, don't do it if your amp is a SS amplifier. All SS amps have a connection to ground and, just like placing too many GC's on a solid state preamp, I am pretty sure this next hot idea is just going to turn one or both channels off. Won't hurt the SS equipment and should clear within a half hour of removal, but I would expect problems for 100% of SS gear.

Bud, How about if I try it at the Speaker end?

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.
