Can the P20 meters be calibrated?

Thanks. I really wanted to love the P20 however it didn’t work out for me.

Keep in mind measurement of distortion is dependent on a number of factors including the noise floor of the instrument itself, how sensitive it is to low level distortion components and the bandwidth of the instrument. It stands to reason unless both are the same for the distortion analysis algorithms and hardware being used to monitor the signal the two aren’t necessarily going to yield the same measurement. Unless you’re certain there are no differences between implementation of the hardware and software in your instrument and the P20, you shouldn’t expect identical measurements.

I think you are confused. I was only talking about ac power distortion and I checked it with a known good meter. Distortion is distortion.
Look at all the harmonics in my first post.

Btw. The meter in question is battery powered and calibrated.
Also in the end the sound is the most important and the P20 for me did not deliver. Sorry.

One has got to be tough in the world of audio.

Thanks elk. You made my decision much easier.

What will you use for your monoblocks and source components? Do you have enough wall outlets or will you use a power strip? Power conditioner? With all that money back, you can really be creative.

Time to move on to another device, or go “au naturale”. You may wish to include a note to the PSA Team upon your P20 return.

FWIW, I, for one, do not think it is unreasonable to expect the data reported by the P20 to be reasonably accurate. The meters may be playthings, but if the unit does not otherwise report what it purports to report and regulate, then I think that it is a problem.

Does the P20 show input specifications and output specification on a selected screen/menu setting or are the meters the only thing purporting to report on the performance of the kit?

Yes. I already put my system back to the way it was before the P20. I’m just glad I didn’t take my rack apart to permanently install the P20. I am so disappointed in this product. The only good thing I can say about it is it’s looks and the meters. Too bad they are only for amusement.
This turned out to be a big waste of time however now I know it won’t improve the sound quality of my system and my bank account thanks you all.

The meters show input and output voltage and distortion that are also reported over the network to the PS Audio’s Power Play interface where these numbers are charted over time in a very nice interface however turns out is reporting false info.
I could possibly live with this if the unit performed well and made my system sound better however it does not.

Here is my final P20 charts on Power Play:

In and Out Distortion over time.

In and Out Voltage over time.

Power / Wattage over time.

Temperature over time.

I sure will. I printed this topic out to include with the return.
Thanks everyone for your help.

I put my system back the way it was before the P20.
The large soundstage returned along with the great sound quality.
I am happy now that the P20 is packed up and ready to return.

My modified PPP is all I need for my source gear. It sounds just as good as the P20 did for this purpose.
My two (2) SurgeX SX-1120-RT filtering and protecting my amps work very well and the amps sound perfect with them.

Upgrades aren’t always upgrades. You know what makes your system sound right, Jeff. :+1:

It is always best to do what makes sense to you, for whatever reason.

Yes they will. I was so disappointed it didn’t work out. I never even removed the clear film on the top cover.

Hey - I’ve never taken the plastic film off any of my PSA gear! :rofl:

Nor me.
