I'm also just curious as I'm deciding wether or not I should buy / audition such a thing. I don't really believe it can make such a night and day difference, that's the thing. So what is it exactly that you're supposed to "hear" (or better, don't hear) with such a product? Is your current multi-thousand dollar setup really that noisey if you run it through a regular power strip? Mine is rather clean already, although I know somehow that my power isn't all that clean (lots and lots of wall warts in the house).
