Power Conditioning for digital source;

You can start with a basic Blue Circle PLC Thingee.

Jedinite. Have you tried putting the Enacom AC filter into the Belkin noise isolater? My experience with the AC Enacom is it's worth experimenting with location. They can have a very nice effect. (I wouldn't sell mine- even though I have other expensive conditioning products)

Hi Ptss

Thanks for sharing the tip on the AC Enacom. I'll try shifting it's locations. I have a spare outlet on the Topaz as well as a spare outlet on the Belkin to try it on.
