I would avoid plugging a high power amp into any power conditioner, especially ones that are are transformer coupled. I've heard stories that they rob power and can actually damage your amp. I think this whole power conditioner product scheme is a waste of $$$ just like magic audio tweaks.
This is the reason I dumped my Belkin PF60. It employed multiple transformers and chokes to achieve its goal of clean power.
Like Chris suggests, I would love to have implemented a large enough UPS system in my house to feed my system. However, the finance director (wife) did not feel the same way I did about audio/video excellence.
