I wasn’t really talking about the sound. I just don’t understand how any currents can flow into the box without both a + and - wire attached. I wonder if you attached the ground wire of your turntable to a ground box instead of the phono preamp ground it would work.
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?
