Did anyone experience Audio Prism's Ground Control

I'm using the standard model on the tweeter/mid connections and the the reference model on the bass on the Vandy 3A Signatures. Tried the refs on the back of the amp for a while but they make the most difference to my ears on the speakers. The sound is more open and easier with them in place. A worthwhile tweak IMHO.

Hi Scott,

I would be surprised to find that the standard GC's worked well with headphones. I would think that a modified device would work well though. I have them on my phono cartridge and tape deck heads and preamps. These are special designs of course, using far less of the materials than the standard GC's are built with and hand tuned to suit the particular purpose.

Headphone amps might be a place to try, but I would only recommend a standard RCA, perhaps plugged into an RCA to tip and ring plug adapter. I have made tip and ring GC's for an M Audio outboard DAC that worked quite well, but we haven't elected to make a niche product like that available.

I can probably get authorization to build and sell prototypes and special production orders. I haven't yet asked about this format for GC's. I am under some legal constraints about what I can and cannot do with GC's, just to get them to market.

I couldn't help but wonder since the ground control
has such a profound effect on my DeVore Super 8's.
My main headphone amp is the Naim headline 2 without
the rca's. It has a 4 and a 5 pin plug. So, I don't
see an option here.

I am looking at some high end phones which can
be rewired. Not sure if I will end up with
Sennheiser HD800, Beyerdynamic t1 or a Grado.

Not sure what a tip and ring plug adapter is.

I was wondering if it would be safe to try using
an rca y adapter on my dac with the rca ground control
on one and my ic on the other. I would like to try
one on my dac, but I do not have any unused rca's.

I am sure you can use an RCA Y adapter to apply a GC RCA unit. Make it the shortest adapter you can find, one with the least metal and dielectric possible.

For that matter you could also use a Y adapter for the headphones, with a tip and ring male plug attached to a female RCA and plugged into one of the Y's. I have no idea how this would sound, but no harm can come from trying it out. You may need two RCA GC's to make this work, unless the particular headphone has a common ground / return wire, rather than separate ones for each channel.

A tip and ring plug comes in a variety of sizes, 1/4" mono, stereo and balanced stereo, with similar types available for mini-plugs. These are just the official name for the plugs usually found on the end of your headphone cables.

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