Did anyone experience Audio Prism's Ground Control

Tvad,

I had a similar effect with my EVS as well. Mine sounded bright and grainy compared to my AP's. Bud is absolutely correct on the permutations with the AP versions as I heard this effect clearly Friday night and Saturday after installing my next set of AP's. I bought 3 standard RCA's to place on my unused amp inputs, reference HT receiver and found they did just that. Now, they have stabalized. I have placed an order for 3 ref RCA's and 2 more standard RCA's to play with adding in tandem to my receiver to add some detail that seemed to spread out and also to my preamp and go from there.

Bud, how many cycles do you believe it takes to stabalize? I seem to get the final settle in around the 3rd day or so. 6 moons seemed to have the same effect, around 72 hours or so.

Odd

This sounds like an interesting product. But I am putting a 8' ground rod and connect it to the chassis of the preamp. Will my system still benefit from AP GC?

Oddeophile,

To completely stabilize, in my system, about 6 to 7 hours, but then my system is already full of the things and has been for three years. 72 hours wouldn't worry me, but I might become impatient....

Vet93,

Yes they will still work. Maybe better maybe worse. There are just too many variables in individual systems for me to say something absolute. I will point out that they have a money back guarantee return policy. Just send them back within 30 days. I would suggest you start with a pair of Standard lug GC's for your speakers. If that provides something you like then slowly investigate additional GC's until you are satisfied.

Bud,

I think I still heard some additional changes to the last set of RCA's I added last Friday night, last evening when I came back to the system. Sounded bigger/larger fuller sound stage again last night. Huge and open in fact, as in real life. Frankly, scary good. I still have to work on adding ref RCA's and standard RCA's to my preamp and BD player as well as PS Audio PWD DAC to see how those go. I have on order a couple that came in to you that were shipped yesterday but Galen should be sending you another order today as there was a mistake in quantity of the ref and standard RCA's as I needed one more of each. I want a full, final, complement on hand to review and determine in/out finally makes it all work otherwise its hit/miss with taking some out to move to another location as there could have been an additional synergistic approach I might have been missing.

It seems in my system adding ref/standard to each component improves the large, full sound stage presentation preserving the detail with the reference GC on the same component. I hope that holds true for the final assault for the last order coming through I hope you could ship today to come on Thursday or so, so I can begin to make some final judgements this weekend. Anyway, these are really superb devices and do fly in the face of reason (For those non-technical folk out there like myself). But they are just becoming "I can no longer live without" devices along with my Walker Audio Reference + HDL's that just makes such a huge difference it is quite shocking and amazing. Your original versions work so much better, for me at least, than the competitor model it was quite a surprise. They all worked to one degree or another, but not to the degree the reference/standard combination has for my system.

Thanks, Bud!
