Did anyone experience Audio Prism's Ground Control

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.

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.

Hi, Budp. My criticism of the gentleman in the 6moons review was that his sidebar answers were described hear in this forum as non-answers and laughable. I will let those with that view answer for themselves. I don't know if those members have even tried the Ground Controls. I have used the Ground Controls and can speak to the positive effect they have had in my system. On my power amp and speakers. So for me it is more important to talk about what I heard with them in my system which was positive. And not let what in my opinion (and others) was not a strong defence of a very good product.
