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.

Ozzie,

The only light I can shed on the long term need to unplug Ground Controls, is that I do not need to. The catch here is that my system is not on 24/7. In fact, it is rarely on for more than 4 hours at a time, perhaps 3 times a week. So, my GC's are certainly discharging.

I will say that it takes a full CD before I have wall to wall floor to ceiling and 30 miles deep sound staging from the system. After that, the imaging and tonality remain stable for as long as I care to play music. But that CD worth of sound field expansion happens every time I turn the system on. I had been ascribing it to the tube power amp getting up to temperature and all of the electrical fields becoming stable, as that has always been the case with this Audio Prism Debut amp I have. Perhaps the GC's are also contributing and I just don't notice a difference. It has been a number of years since I mounted these GC's, so my memory for such trivia must be considered suspect indeed.

It’s said that mixing the Reference GC’s with the “regular” GC’s improves the soundstage. So my question is, is it possible to buy GC’s that are terminated with Banana Plugs that are not terminated with the Reference Banana Plugs?
Yes, you can obtain a "Standard" Banana plug. My personal recommendation is the locking style from Radio Shack. You need to place a special order for them as we do not ordinarily provide this. You can contact me through Audiogon directly or google AP Labs (AudioPrism) and email Byron.

I had a little grounding issue between my VPI turntable and my tubed phono pre.I decided to try the spade ground control.I took them off my amp and put one on the ground at the phono stage and the other at the ground on the vpi table.
I already had a ground going from the TT to the phono stage.I was surprised that the ground control helped the grounding issue,but also added more clarity as well.

I will be leaving them on the phono stage and VPI turntable and ordering another set for the amp again.
So after all this time, I decided to try once again a used pair of the Reference spades for my speakers. 

Its funny because the Ground Control items became all the rage for quite a while then disappeared completely. (including usage by myself). 
I can't remember why I stopped using them and then sold them. Anyone else comment on this ?
Anyway, I decided to try them again on my speakers I should have them later this week.
