Thanks, Ted! I do appreciate your openness and your taking the time to contribute here. I learn a lot from your posts.
After some trialing a P12, I decided to go nuts, return it and get a P20; I might need the capacity down the road.
It just arrived, brilliantly packed, i must say, and I was able to unpack and set it up alone, 100 pounds notwithstanding—the handles are perfect.
Yes, stuff I’ve never heard before from recordings I’ve enjoyed for years. And the quality of the voice of horns, Philly Joe Jones’ solo with brushes now revealing the contact with the skins and cymbals. I’m thrilled. I know I’m going to be up all night.

Couldn’t agree more. My system with a BHK 250 amp could have easily been handled by a P12 from a wattage draw standpoint. But as Paul has said several times, wattage draw doesn’t tell the whole story. So I went with a P20 (from a P5) and my system has an effortlessness and transparency that keep me glued to my seat on many CDs and LPs I thought were just average before. The image just floats out there behind my speakers as though the musicians were really there. And the bass–again, effortless (not boomy) and convincingly real. If you can swing a P20 don’t give it a second thought even though it might look like overkill from a wattage standpoint.

Ron,
Say it ain’t so!! Did you consider the P15? I have the P10 and upgrading to the P15 is much more realistic for me. However…
Muh Brothuh, it’s a sad, sad story, all of which is true. This thing kicks ass. (oops–can I say “ass” on this thing?)

Thanks for sharing this! The P20 is indeed a revelation for anyone not yet trying it.
Yes, Paul. It’s something you don’t need to try to hear. It’s right there in your face; everything is bigger, better, fatigue free.
My experience as well. I don’t think it took me more than a minute to go Holy Crap! It was an amazing experience that first time.

Playing around with tuning my P20 tonight I noticed that with the evening comes higher power out of the wall, as expected.
Daytime, inlet runs 112 to 115volts. Evening, 120.2.
During the day, the auto-tune function will set Phase to +3. I just ran it again at 120.2Volts and it set Phase to -1.
Then I changed from High Reg to Low Distortion and heard a noticeable improvement.
Would it be feasible to implement some algorithm that would read the delta power and adjust or auto-tune these parameters for max performance?

I’m interested in this too. I have a P12 and am a bit confused as to whether set the mode to high regulation or low distortion. I’ve changed it to low distortion. The autotune sets my phase to zero; though I cannot remember, if I did the auto tune at night or during the day.
My preference is always for lowest distortion. Maintaining a long term voltage level isn’t as meaningful in my opinion.

Thanks Paul. But what if your typical daytime input voltage drops from 120 down to 110? Still set to “low distortion”?
No. If that’s the case you’re better off with regulation. Sorry. My long term. Olathe is quite steady.

Thanks Paul!
I find that Auto Tune gives a different value each time it’s pressed, ranging from -1 to +2.
My incoming power is 120 in and 4% THD.
Should I just leave Phase at 0?
If you are getting 0.4% THD out or lower at 0 phase, I would leave phase at 0.

Thanks Elk. Yes, I’m getting 0.1% THD out.

I say play about with Phase. I get very low distortion out and also get varying values out of AutoTune. Sometime it takes me to +4 and then others -2 and there’s really more than a subtle difference between these and also between 0, where I generally let it rest. Somtimes I feel like a +4, sometimes I don’t.
If you hear a difference and like it, go with it.
Hi @lonson
I hope your father is recovering well. I feel for him, especially in the winter.
Re auto-tune, I get a mixed bag too and could never understand the reasons for the different figures. Also, when auto-tune is on 4 the graph of the output voltage in Power Play shows a wavy line, meaning voltage is not steady. When I put it back to 0 voltage output line goes infinitely flat. Did you notice something of this sort?
