Forget the PS Audio stuff. You see tons of them on the used market for a reason. Get an Audio Magic Stealth Purifier. I own one, and love it. Better than the Shunyata, the PS Audio 300 and 600, and.the Panamax, Infact, it's better than anything out there. And it's affordable. I did my homework on this baby. You can get(the small) one for just your digital stuff, or the big one for everything. Just plug it into the wall. Put a hospital grade outlet there, and you're done. Home depot: $15.
RadioShack outlets VS. Panamax.
I've recently realized that Panamax1500 filter that I currently have in my system nearly does nothing in terms of neither protection of the components nor noise isolation.
