Have any experience with Richard Gray power stuff?

I have the little 400 unit. It really does help the black levels on my Toshiba 40" RPTV, kinda weird.. For audio purposes I am really not sure. I think is your equipment has smaller power supplies, the better the performance gain might be. I have all Simaudio stuff, and their solution to all life's problems seems to be "an oversized power supply".

I put it on the line with the two subwoofers, and I think it help out a little, kinda hard to tell. I have heard from more than one source that by using more than one/larger model the benefits increase...Sounds like the shampoo line. How to double your sales in shampoo, say repeat.

I would like to know how these things are different than a UPS.

A buy used type of item, in my opinion.

I also have a Richard Gray Power Company 400S. It helped improve the overall sound from all (treble, mid-range and bass) ranges. The sound was smoother without any loss of detail. Most importantly, I use to have major components hooked up to it (now I have five dedicated lines). I had a bad power surge that blew the fuse in the RGPC 400S, thus saving my monoblocks, preamp and cdp from a fate that I do not even want to think about.

I've heard others comment about RGPC line conditioners being system dependent. If you can try before you buy, that would be the way to go. However, it worked very nicely on my stereo equipment and TV.

I used a couple of them and I can emphatically say---I'm not sure. I feel they MIGHT have helped my audio system. It seemed to sound a little cleaner but when I took it out, I couldn't really tell a definitive difference. I decided if it was that close I would sell them and move on to the next experiment in tail chasing.
