Did anyone experience Audio Prism's Ground Control

Nicely said guys. I appreciate your mention of the cables you use Ozzy, answers one of those blank spaces of system composition and their effect upon the Ground Control pieces.
Just as pleased as you are that the Ground Controls worked in your system.

Three days ago I loaned my transformer attenuator preamp to a colleague. He provided a SS Nikko Beta II preamp. Typical hashy leading edge to mid and hi frequency, SS sound, from products made back then.

It has two RCA output jack sets, so I plugged a couple of RCA Ground Controls in place and not even the reference ones either, one at a time, just to see what happened. I now have an extremely transparent, very sweet and colorful preamp... and I think I like it more than my stepped attenuator passive device, with my own high zoot transformers in it, just to add insult.

I will mention to Byron how weak, vague and shaky his interview was Jejaudio. Which review were you referencing?
He is one of those Afrikaners from So. Africa, so I suspect I will get a sharp response and a laugh back!

Budp 2/25/10: if you have poured ground planes in all of your equipment in the amplification chain, or you have a fully differential amplifier, without direct reference to true ground, they will not provide you with any benefit.

Ozzy 4/28/10: Well I finally had one of the Ground Controls for about a week.
I will admit that these little things dont look like much but they do provide a marked sound quality, improvemnent in my system.
Music seems to be much more relaxed or natural and the soundstage is deeper and wider. Vocals are very nice and defined closer to the real thing.

Ozzy, aren't your Pass Labs preamp and amp fully differential?

Almarg, I am using the ground Control spades at my speaker ends.

Budp, I thought it was important for me to post since I was so negative previously on this post.
I dont have any idea why a short little thing like these Ground controls work, but they do.

My Classe S-700 is a fully differential amp. And I have used the Audio Prism Ground Control on my amp and speaker end with good results and no problems at all.
