With all the controversy surrounding the measurement of the P12 Power Plant we thought it useful to show how the measurements for output impedance, distortion, waveshape, etc. are properly made. Who best to show us than the Power Plant’s designer, PS Audio’s Chief Engineer, Bob Stadtherr. In this video we measure the P12, show why it matters with impedance, explain MultiWave, and show why it’s important to have low distortion sine waves (not because the harmonics are bad but because they are a symptom of what we don’t want, flat topped AC).
Glad to see the video of Paul and Bob explaining with measurements the benefit provided by a Power Plant. This is so much the opposite of the misinformation being put out by the likes of ASR
Paul thank you for providing this video on the functions
of the P12 and power regenerators…Bob Stradtherr/s
walk talk through is invaluable.
The illustrative screen shots of the incoming clipped sine wave
and outgoing regenerated sine wave has long been
needed…as well as the numerical chart showing the %thd
incoming and outgoing…
The first thing I heard when I plugged everything into my P12 way back was the sense of ease it took to the music. The lower noise and the uncompressed dynamic on the drum recording. It impressed me so much, I dragged my brother over to hear it. My brother heard it and ordered a P12 for himself right away! He also absolutely loved what the P12 did in his system. End of story.
Ask your wife if selling the sewing machine and using the money for a PP, which will take the spot formerly occupied by the sewing machine works for her.
Be sure to have a pillow and blanket stashed somewhere outside.
Thoughts?
I think that’s hits the point of the issue. Amir did not test for the purpose of the Power Plant. He did the same test he does for just about everything. The noise that all these components emit is so low what is he looking for? this DAC is .0000001 and this dac is .00001. In reality whats the difference? But how do they sound? The test Paul and Bob did is to show what the unit is designed to do, period. After that, its what did it do in your system.
The interesting thing happening in this small community on the internet is everyone is starting to talk about these tests… sides are forming… its quite interesting to see what these people we watch weekly think of them. Darko, Thomas Stereo etc. all ringing in.
