All i'll say is you've got to try them first. Sometimes it can make a decent difference, sometimes no difference at all. It's rather an inexact science. Because of that I suspect these grounding boxes are probably correcting some sort of design flaw in the equipment, probably with (duh) grounding. I still use a Silver Minimus on each amp's negative speaker post plus an Olympus Minimus on DAC, Melco. I'm not utterly convinced they make a huge difference but I think when I had my Devialet that the improvement was a bit more tangible.
