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.
