AC Regenerator

However, it still sounds better late in the evening than in the daytime. So, by audiophile standards PPP is not good enough. I'll probably upgrade to P5 or P10 at some point.

Incoming THD is 2.0% at best and usually worse. In the past two years I made four upgrades: 1. PPP - biggest improvement, 2. Purist Audio Neptune interconnects between phono stage and integrated amp - second biggest, 3. Purist Audio Dominus RevB Ferox power cord for the amp - third biggest. But all three were quite big. I also got Tchernov Reference MK II interconnects that I use from phono to tape deck when I run the system like that, which is often. In this case Purist goes between deck and amp. In fact, in my system this arrangement gives overall the best sound from vinyl.

PPP that I use does not restrict dynamics and makes everything better, including the dynamics. The wall current here is terrible, unstable and very dirty. My amp is 120 Watt/Ch, the entire system is plugged in the Premier. Power cord from the wall to PPP is Custom Cord Company Top Gun.

Well, that should probably be extremely high quality components when we have a current like that. I didn't try Gryphon or Lamm in my place, this would be interesting.
Elizabeth, that's good to know. I think some turntable motors dislike changed frequency as well.

I remember years ago someone here was talking about Phillips medical grade device he stole somewhere. He preferred it to everything else he tried and he tried just about everything.
I'll keep this in mind, thank you, perhaps that's exactly what I should try next instead of upgrading the regenerator.

Give it 500 hours, it may change and it may not.
