Did anyone experience Audio Prism's Ground Control

Thanks Bud. I will have to look into this when I decide on which headphones to buy.

Tonyjack,

Thanks for the info Tony. I will have a pair of subs coming on line in a few weeks and I will try your tip about the reference GC's on the woofers, with standards up top, which is what I currently have, with two reference's on the amp.

Hi all,
After following this thread for a while and reading the various reviews of the GCs online, I finally decided to try a couple of pair on my biwired modified Apogee Duetta Signatures (for those not familiar w/these, they are full range ribbon panels from the late 80s). And the results are in keeping those already reported by Ozzy and others---soundstage more defined, deeper, and wider; each performer better defined in his/her own space; a cleaner, clearer sound that has more impact, texture, and a more solid foundation.

These things are definitely keepers.

Well done, Bud. A great device.

Rlxl,

Thank you for your kind words. I am pleased to hear from a large ribbon aficionado. Seems that all that is left is a large horn system. Maybe I can talk Romy into insulting me?

I will of course invite you to look into a pair for your amplifier/s At that point, the RCA's begin to make a noticeable difference, especially when applied to a commercial CD player without an out board DAC (assuming aanyone but me has such a device any more). I have also found them to indespensible for solid state electronics of all kinds and could not be parted with my Nikko Beta 1, so long as it has the RCA GC's attached.

Thanks to everyone for trying them.
Bud

Budp,

I've been very happy with three pairs of Audio Prism's Reference Ground Control Spades on my speakers. However, they did not work well on my fully differential solid state amplifier. My fully differential CD/SACD/DVD player, with a tube output stage, goes directly into the amp without a pre-amp. Would the Reference or Standard RCA versions on the digital output (RCA coaxial) and on the video output (RCA) be beneficial for audio quality.

Best Regards,
John
