FWIW, I have the RIchard Gray stuff hooked up in my video system, which is totally separate from the hi-fi system.
The hi-fi uses 20amp dedicated lines and shunyata hydra/anaconda, etc. One noise I simply could not eliminate was a electrical snapping sound whenever the air compressor for my airline arm kicked on- the compressor is located in a separate room (more like a large closet) with separate power lines. But, even after adding an expensive relay supplied by Kuzma for the compressor, the zapping noise would still appear. Almost sounded like the stylus being pulled across the record.
The solution was to plug the air compressor power cord into the Richard Gray step-down transformer, which is a big ol thing, takes 220volts from the wall and brings it down to 120v. This may have nothing to do with the quality of Gray's 'proprietary' conditioning technology, and everything to do with the use of an what I guess is simply a big isolation transformer. But, damn thing works. It is also used to power the projector and a host of tube amps, processors, etc. for the video system.
