I think I have the worst AC coming into my house. I am amazed how the P20 makes everything right. ![image](https://us1.discourse-cdn.com/flex015/uploads/psaudio/original/3X/7/a/7a041c53cfc0fe60b6e9b1b9f6c4a8e5584273f1.png) ![image](https://us1.discourse-cdn.com/flex015/uploads/psaudio/original/3X/2/e/2e334a75d63295009fe7bf71b4f36290121f0ccc.png) ---

Oh my! That distortion is very high, magically brought down to about 0.2% and kept there. šŸ‘šŸ» . My mains voltage jumps 8 volts, then dips about 6. However, the P15 keeps it where it should be šŸ™‚ ---

Iā€™m lucky to have very good incoming power, my PP shows 1.1% THD coming in. ---

I am right there with you, I am very lucky to have a P 20 . ![image](https://us1.discourse-cdn.com/flex015/uploads/psaudio/original/3X/1/5/155b4f89307190e208fc22745ddf6c127361b0f2.jpeg) ---

Thatā€™s pretty high incoming THDā€¦surprising for a US based utility. ---

My friend down in Crntral Florida has been working / fighting with Duke Electric for the last five years, trying to get them to just give him remotely stable voltage. He has a meter hooked up, and the reading goes anywhere from 113 VAC to 127 VAC. Really makes the sound of his system completely unpredictable. I told him to buy a P15 šŸ˜€, but he really doesnā€™t have the space for it in his very small sound room. After all the years gone by Duke finally seems to have the voltage stable to about +/- 3 volts. ---

I think you might have neighbors with a hot house marijuana growing enterprise. All those noisy UV lights, switches and circuits. Are the folks around you unusually complacent? šŸ˜ ---

Depending on time of day or night, my incoming THD varies between 0.4% and 0. 8%. THD out is always about 0.1%. However, my voltage varies by +8/-6 volts šŸ™„ ---

So I kinda became obsessed about getting exactly 120v. I went into the settings and made it happen. So, just like your photo shows, if I never got the 120 on the button. I would achieve about 119.6. So the question I have for the more intelligent people on this forum, why didnā€™t the PP just do it on itā€™s own, instead of me fiddling with it? I thought that is what it is suppose to do. So donkt150 why didnā€™t you correct the 118.9 and ā€œmake it soā€? Just curious. ---

Same with my P20. Set on 230V, but always below. Why? ---

I noticed that if I do not change the settings for a couple of days, distortion and voltage output stabilize as if it auto learns. ---

For me, itā€™s all about the sound. In my system it sounds best to me set at 118-119 volts , I go by what sounds best to me and I donā€™t stress over it. ---

Because the precise voltage really doesnā€™t matter. What matters is that it remains stable as a rock. I prefer 118 or 119v. ---

Calibration settings are accessible and adjustable - please have a look at this thread: > [@P20 calibration question](https://forum.psaudio.com/t/p20-calibration-question/11834/14): > > I see most of the point of the regenerator is the lowering of impedance and stable voltage It really doesnā€™t matter if the output is 230 or 230.1 or 231v, the stability will be the same as will the impedance In other words, donā€™t fret over ā€˜calibratingā€™ it, plus unless you have a calibrated volt meter you really have no reference ---

It is rather impressive what the PowerPlants are able to pull off. I also find it impressive how awful your incoming is. Some of the worst Iā€™ve seen. Way to go P20!
