    Looks suspiciously like the Audio Prism Ground Control, for which the designer provided this explanation:
    There is a small triboelectric effect that helps to accumulate the electrons that jitter into these things. Causes more of the vacant orbits to become useful for the support of ever smaller signal events. The charge buildup between wire and dielectric additions are what needs to be charged.

    The GC are there only for the back half of the wave form, what has already passed through the load and thereby becomes susceptible to all of the dielectrics and metal to metal contacts between your system and wherever lowest ground potential happens to be in your system. Thus GC acts as a very low RAC and RDC unterminated wave guide, with significant momentary storage and because of this provides signal with a choice of wave guides.

    At least, this is the current postulate.

    A number of ML Club members have purchased them and report positive effects in sighted evaluations. The explanation given above sounds like balderdash and I remain skeptical.

    Ken, I particularly like this language from the linked website:

    So, what are these things and how do they work? These Ground Enhancers are simply tuned pieces of wire that add a low impedance localized ground storage that enhance the sound in ways that are dumbfounding. Actually, no one really knows what they are doing, but this makes the most sense.
    Peace.

    I'm highly skeptical as well about attaching something that looks like a kid's friendship bracelet to my binding posts making any difference at all. As always however, I must follow the code.....If I haven't heard it, I don't have an opinion

    Apparently Audio Prism is the company that originally came up with the green pen thing for CDs. They were at RMAF this year. The Stereophile report on that is here.

    LOL!

    Ultraaudio published their Audioprism Ground Control Cables review online today. Their conclusion:

    There are many positive comments out there about AudioPrism’s Ground Controls, from reviewers and others who have already experienced them. My system, however, didn’t benefit from them, nor did a very different system. The Ground Controls indeed altered the sounds of both systems, but nothing I heard could be called a worthwhile improvement.
