I have had a PS Audio P1000 since 03 and overall it has been a plus in my system. There is more of a bIack background and the midrange tonality is a little clearer. When the amp is plugged in to it the bass is a luttle leaner but more defined. I run it on 60 hz. I have had my amp oscillate. I guess you could call it. It would softly drone in and out on multiwave. It will blow a preamp fuse now and then. Usually when we have a split sec power disruption. I don't use clean sweep anymore after blowing fuses. Don't hook up anything with a motor to it. It is a bruiser. I used to hook up a 600 watt amp to it now and then and there no problems except heat. And I bigger power bill! Regenerated power is costly with a big amp plugged in. I couldn't tell any loss in dynamics. However smart people here have wrote that the amp would exceed the amps or amperage of the power plant. I can't remember. I disconnected it from my system 2-3 months ago and just used a power strip. At first I said huh no difference. So I listened for about 2 weeks then switched back. Ahhh there is a difference. I don't believe in quick AB testing. You really have to get to know the equipment and the equipment changes you make. I'm using my SACD player in just the filtered outlet and it sounds better to me. My system was sounding worse about 2 weeks ago. I made some changes and something corrected itself and now it sounds great and I don't want to touch it. In all honesty it could have been some dirty power coming down through the lines but thats what a power regenerator suppose to correct!!! Late night listening still sounds best. Must be something atmospheric I don't know.
