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 vi…

Hey leean welcome…PS Audio makes very wonderful gear aimed at improving, maximizing our audio experience… I Have owned several PS Audio power plants and loved what each one brought to my system… The upgrade path has lead me to my P15 regenerator…truly a wonderful piece greatly improving my syst…

I only glanced at the doc, but I may be able to somewhat explains where the DC comes in. This may be where certain individuals are harping on the AC-DC-AC shtick. Just from looking at the flow chart, the incoming AC is used as a basis to create a 5v peak to peak signal. That 5v signal is used to …

The Correct Way of responding to Measurementalists (objectivists who believe a Measurable aspect of a Thing is equivalent to the Thing) is to ignore them.

Can you believe Amir the Merciless has posted YET ANOTHER VIDEO with a 10 minute rant at the end about one of Paul’s posts above. He seems to on the point of tears. I scanned it as it was painful to watch. I’d have been ashamed if one of my kids had moaned like that when he was aged 10, let alone 65…

I’m a P12 owner, and I would love to see a PS Audio response to Amir’s data on the P12 not regenerating AC.

No, the P12 and all modern Power Plants are not traditional regenerators (which are 50% efficient). They regenerate and regulate the hot side of the AC line with a tracking power supply in an effort to improve efficiency (which is now about 85%). Their purpose is to lower impedance, regulate the AC…

Thank you Paul…a great service you have provided our systems with…and because of the efforts you and Bob Stadtherr we can enjoy a more articulate sound system. Certainly this is the case for me going all the way back to about 1996 with the Quintessence and Soloist. With every step along the way…

That’s very interesting reading @st50maint , thanks for sharing that.

But doesn’t explain this slide from ASR’s video.
