Grounding Box Q

I watched a rather long video by Calvin Gabriel from Shunyata talking about his grounding boxes. Let me just say that, based on the large number of people buying these and other expensive grounding devices, I believe that they must do something positive, but here’s what I don’t understand.  If only a ground wire is plugged into the box, how can any current flow into the box?  I thought you need both positive and negative.  Or is it something like the ground wire on a turntable, where you just hook up a ground wire and it kills the hum?

I tried the Shunyata Altaira Grounding box and I actually got hum from its use. However, I do own the Entreq Silver Tellus and I have made several DIY versions that work quite well.

I think the Shunyata usage is more of a star grounding scheme, that may or may not benefit your system depending upon your system ground. The others I own/built try to drain away line borne distortion which travels on the ground. Which when reduced does surprisingly result in a much deeper and cleaner sonic image.

Most of the commercial products are way over-priced based on what I put into mine and how it performs.

Some of these units are designed to be used as chassis ground and some are signal ground. Typically, the chassis ground units are also connected to the wall AC ground, sorta like a "Star" ground. Strange as it may seem it does make a difference.
