surprised that the P20 ships quicker than the P15. I’m still waiting on the P15.
My P20 was suppose to take as long as Darren’s but then I was told it’s going to take 2 full weeks.
Brodric - The performance data works fine on the PS Audio control website, once I got the usage strategy worked out, thanks to you and Elk. Here is the data snap shot for June. Yes, it does work and I will get wattage as long as the unit is turned on properly. Anyway, thanks to you and Elk, appreciate the help.

Does the P20 and the smaller ones have a socket that’s routed through to the wall socket without regeneration?
I ask because if I want to use it as power distributor and don’t eat to connect i.e. a sub, I then would not have to plug it into a separate wall socket.
No, they do not.
Thanks Paul!
Does it make sense not to connect an add. sub (even with a P20), assumed usual strong power amps like the BHK are used for the main speakers?
Excellent!
BTW, I connect subs to my PowerPlants.
Jazznut - The P20 has (5) groups of outlets and so many options for turning each group ON/OFF. In addition, the P20 has massive power capability. Why would you want to bypass P20 regeneration for all things requiring a lot of power; especially subs. I think the P20 would really benefit subs; and, or amps powering just subs? In addition, you can delay turn on for warm-up… I’m using the P20 to power to a PSA BHK250, PSA DAC, and PSA DMP; calling that a really light load… 
Also, my SF Guareni Evolution speakers give me plenty low octave sound in a small 12ft X 22ft X 10ft music room. Moreover, I added ASC isothermal bass traps (16in X 9ft) in the front corners and 13in X 9ft cylinders on the reflection walls next to the speakers to reduce the lower octave pressure wave and tighten bass. Going to a sub in that room would be very interesting…
As far as I know, P3 is the only power plant that has that feature.
And the even older P500 power plant
This question may have already been asked, but I’ll ask anyway: how much power (watts) does the P20 draw when in idle “standby” mode? Same question for P15.
The owners manuals says 35 Watts for both the P20 and P15.
I agree with Elk. I too connect subs to the Power Plant. Subs are less noticeable in the system than the main speakers so the benefits of the Power Plant might not be quite as noticeable on subwoofers as they are on the main speakers, but it surely makes a difference.
thanks but what I meant is: don’t subs pull too much power from the regenerator and waste its reserve in relation to the smaller benefit?
The subs pull hardly any power…my power amps suck up a lot more power than the subs.
Jazznut - I think that is what Paul was explaining and Brodric commented. Low frequency, as a function of the whole audio spectrum, is small; however, requires power during those needs. A P20 with large amps and a sub amp would be fine.
yes, I think if they do it’s more the dynamic peaks, they suck in parallel to the rest
It is also common for a sub to have a Class D amp as its onboard amplification. Class D is typically quite efficient.
I thought (quite possibly mistakenly) that Class D automatically means “switch mode power supplies”. It has been my understanding (and experience, with GCC-500 / PPP) that switch mode psu’s are surprisingly taxing on a power plant. Something to do with “power factor” ?
That is incorrect, Paul. In fact Class D is only referring to the amplifier itself. Take Hypex, for example. This company makes great Class D amplifiers and couples them with conventional analog power supplies. I don’t believe they even make a SMPS (but that was some time ago).
