"If your goal is only improved SQ and not protection then another alternative would be the Alan Maher's Hammond 193L Choke Tweak that's very popular on Audio Asylum and Audio Circle. Some years ago someone took apart a well regarded $1000 Richard Grey Power Conditioner and found that it only contained potted chokes. Since then people have basically bought equivalent chokes and added them to their system. There are a good several years worth of threads and testimony over at AA. The choke is $50 from Parts Express. Just add on a plug to the end of the wires (doesn't matter which), and plug it into the outlet or power strip, etc. your components are connected to. That's it. I believe you can add as much as 4. The choke draws so little current that there's no danger to your equipment.

It's flat out the best $50 and up you'll spend. It's like drano for all the grunge in your AC. And it does as much for video/tv as it does for audio. You'd have to pry them out of my cold dead hands.

For all the science behind it I would just spend a little time at one of the aforementioned forums or just google.

anyway, some first post! (been lurking a while tho)

good luck"

It's designed to be a low-current HV DC filter, not an AC line filter. I would check with Hammond about this application. The DC ratings are 300 mA and 800 V, and resistance is listed as 57 ohms which is pretty high for a series choke. Not sure how they are using them...
