I use a regenorator by PS for my front end gear. Having said that, I cannot think of any preamp, amp designers who use any type of power conditioners when designing their gear. Having spoken to them not one says they are needed to make a proper designed power supply function better. I like the PS for keeping my voltage steady at 120, perfect wave form minus any line noise. It does work because when I run my vacuum the meters show the incoming distortion and the improvement and they both go through the roof with vacuum runing. So the PS Audio does so what they claim it does. I used balanced units and transformer units and I have kept the PS Audio unit.
