Grounding with a Earth box?

I got no clue what you're talking about.. BUT I'm pretty thick.. What are you saying, they sell boxes full of different soil compositions and say is provides a "Better Ground"?

How is supposed to work or be better?

"How?" is the refuge of scoundrels. "Does?" is all that matters.

do a search for audiophile grounding box or  wood grounding box   to find more.  

It’s just one more scam of many in the audio world. The only reason these scams work is because all someone has to claim is “ I hear a difference “ ....all that science you speak of is useless as long as I can hear the difference!    Well, Ok, I guess it’s game over
