Why assume you need any? Do you have any surge protection for the system?

Tripp-Lite makes an excellant surge and noise suppresion 6 plug outlet. PartsExpress.com carries them for about 75. bucks. The twin banks of plugs are isolated from each other with the farthest pair from the power cord being 60 db down in quieting. It also has connections for your cable TV.

I have found that the mapleshaderecords.com highest model power strip provides a non-current limiting enhancement to performance of both front-end digital or analog components, and even enhanced a fixed powercord amplifier (subjective increase in speed of transients, together with smoother yet more dynamic sound, and cleaner, accurate bass).
This power strip has four parallel wires exiting from it which need to be kept separated from each other on the way to joining at the power plug for entering the AC wall outlet. Creates a bit of a mad scientist wiring array leading to the AC wall outlet.
The name alone suggests it better be doing something right for $340: Clearview double helix Mk II power strip, Plus version.
Although its appearance is sometimes the subject of derision since it is outwardly so plain, even flimsy looking, the audible benefits are very impressive. A family member has used it in a system including a video projector, and felt the picture improved.
I would call it the power conditioner without any visible power conditioner apparatus.

Get rid of the computer filter that you have, it restricts power quite a bit.

Go with the Tripp Lite or something along those lines. I use a VansEvers Super Companion ($150).
