Did anyone experience Audio Prism's Ground Control

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.

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

Hi John,

Under no circumstances should you ever put a Ground Control on a digital ground connected RCA!!!!!!!! Seriously. I am not sure that a fully differential CD etc player would respond any better than did your amplifier to one of the RCA GC's.

We will likely market a set of speaker cables early next year, using the same materials technology the GC's utilize. So, you might save your money for those, they will be absolutely neutral and immune to anything except being draped over a power transformer.

Otherwise, enjoy what you have and perhaps take a peek at Planet10hifi.com. I am sure you have speakers you love, but the EnABL process and Mark Audio drivers, in a cabinet made in Canada, designed in Britain, with workmanship better than the Chinese cabinets and far more musical, might be something to investigate for the future. I can promise significant removal of all of the obstructions to music that speakers force onto us with this combination.

Thanks Bud!

Hi John,

I don't mean to scare you. The RCA GC's to a DAC ground appear to affect the cable load and the clock looses sync and the bitstream quits. This to an external DAC with the RCA on that digital ground. Unplugging the RCA solves the problem in about 2 minutes and nothing further occurs. In my Sony SACD etc player, an external PCA onto the spdif with no external DAC connection also shut down the player. I had to turn it off to get the unit to reset. No further problems. So, the GC's don't hurt anything, they just make em mad.

As for the video application, I have been told that plugging an RCA into a video player is helpful. I don't know anything about these devices so I have no cautionary words. Blacker Black and more vivid colors were claimed in both conversations. I am a bit skeptical, but again, I have no experience here.
