Grounding Box Q

I have the Synergistic Research ground box on my reference system and it works.  I think the improvement in my system is well worth the money.

More confirmation that audiophiles are nuts!

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.
