Following the death of my closest local audiophile friend (for nearly 45 years), I inherited his PS Audio P300 power regenerator. This is their lowest output unit from their very first effort at power regeneration. It sat around here for a while, and then I thought of trying it on the bias supplies of my Sound Lab speakers, which draw very little current and are an easy load. To my pleasant surprise, the P300 made a very worthwhile improvement to overall sonics, but most notably in bass and mid-bass frequencies. "Articulation" went up; noise I didn't know was there before, went down. The P300 subsequently went bad, and I really noticed the loss when I had to go back to using the wall socket as a source to power the bias supplies, albeit my listening room has dedicated AC lines and separate grounds outside. I inquired with PS Audio about repairs, but they won't even look at these early units any longer. My local repair shop punted also. However, PS Audio did offer to sell me a new P3, their latest production with several improvements over the original, at a substantial discount plus the return of my P300 to them. I received it two days ago and hooked it up last night. I immediately heard the difference. This makes some sense, because you don't want any spurious AC noise on the mylar bias voltage which ideally should be pure DC. Any noise on the mylar would modulate the audio signal. If you can borrow a PS Audio regenerator (not just any of the many "conditioners" that don't actually regenerate AC), I highly recommend that you give it a try. If anyone here has already done this experiment, I would be interested to know what you think. I thought this experience was relevant to this site, because OTLs and ESLs go together like love and marriage, or a horse and a carriage, or peanut butter and jelly, or something and something.
