I just installed a new AVS 2000 in my setup today. Had an awful incoming voltage fluxuation problem. It was noticeably affecting all of my equipment, and not in a good way. The voltage is nicely stabilized now with the AVS 2000 installed. I'm sure you know that it is only a voltage stabilizer and does not provide any surge protection or filtering. I still have all of my equipment plugged into a Monster Power HTS 3600 which provides the surge protection and noise filtering that I want, and then I have the HTS 3600 plugged into the AVS 2000. I have no experience with the PS Audio unit that you referred to. I can only speak to the merits of the AVS 2000. It is built like a tank and weighs around 60 lbs. I'm very happy I got mine.
