Grounding Box Q

Some of these grounding boxes cost many thousands and the ground wires can go for 300.00-400.00 a pop.  No thank you, my system is quiet enough without it.  IMHO, it's a money grab from the manufacturers.  I guess they just figured out another way to get money.  I am not saying they do not do anything as I haven't tried them, but can you really and truly hear the difference and is the cash outlay really worth it?

I heard a demonstration of a Nordost grounding box at a dealership.  The room had several dedicated power runs for a dedicated subpanel, and in terms of audible noise when no music was playing, there was none.  Yet, with the grounding in operation it was easy to hear an improvement in soundstaging—solo singer and instruments seem to be floating apart from each other, and the sound was a bit less artificially edgy.  It was a worthwhile improvement in a high end system.  I would rate it a bigger improvement than power conditioning.

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.
