Did anyone experience Audio Prism's Ground Control

Oddeophile, So far, I like the effect with using both the standard and the ref RCA's on my Cary Pro.
But, having both the ref and standard on hand to try in different places is a plus.

Agreed. Something I plan on in the upcoming months. Over the past 3 days my reference GC's on my speakers (I had to obtain 4.5 pairs since I bi-wire and bi-amp my main front and rear speakers) have continued to improve and now have pintpoint clear clean imaging that has blown me away so far. I plan on doing some critical listening on well known material this weekend. For now, I have heard some things that are striking and very welcome. No negative affects at all. All positive. When was the last time you picked up a tweak that was all positive??!!

In my set up there was no question the addition of the second GC for the woofers on the main speakers added to the improvement. I have heard of some folks with mixed results - some feeling not needed while others agree with what I am hearing there was a discontinuity between the frequencies near the crossover where it was clearly audible what had been improved on the upper drivers vs. the woofers. Adding the additional reference GC to the woofers and voila'! Almost instant improvement.

So far, so good and color me happy. More to follow of course as I get a chance to really listen to some well known material compared to what I have had time to deal with so far the past few nights.

I do feel there is additional improvement over time beyond the one hour break in, however. At least to me last night seemed somewhat smoother, more detailed and relexed even over what I heard the second night (night before).

So far, well done Audio Prism!

Received 3 sets yesterday of the EVS Ground Enhancers.

These look very similar to the Ground Controls except without the spades or bananas. Mine have just a straight wire that I placed into the hole on my speaker spade lugs.

I am using these Ground Enhancers on my Home theater system along with several of the Ground Controls.

Well, immediately I noticed much more presence in the surround channels along with more weight and definition.

Thus far, I consider EVS Ground Enhancers to be the equal in sound improvement to the Audioprism Ground Controls.

I am waiting to get mine Audioprism, according to manufacturer, speakers provide the most effect and next is the cd. Does anyone know if you have a speakers like the Verity with monitor and woofer in separate cabinet and connected by jumpers, should I connect the GC to the woofer unit or monitor unit.

Alleung,

For your first pair, I would recommend that you get the Standard Ground Control and put them on your midrange. Then another pair for your woofer.

With that experience you could try a pair of Reference at your amplifier terminals, keeping in mind that you will have 30 days to evaluate them. You can then move the GC's around to see how they affect your system differently.
