Grounding Box Q

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.

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. 

I don’t know how they work, but the Nordost unit I heard at a dealership had to be wired to an unused input.  I told the manufacturer’s representative that my amp had only one input, but I could wire it to the chassis ground.  He told me that would not work, it had to be wired to an input; I took this to mean that the hot side was also in the circuit.

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.
