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…

Ok but have you taken time to watch this very well done P15 review. This review alone puts things right…Reinforces what Paul has said all along. Have a look it is very well done!! [PS Audio P15 Power Plant Review] Best wishes

Now here’s smores for you doubter hangers on: [image] PS Audio DirectStream Power Plant 12 In the November 2018 issue of Stereophile, Jim Austin reviewed PS Audio's DirectStream Power Plant P20 AC regenerator ($9999). PS Audio had sent me the less expensive DirectStream Power Plant 12 (…

Yeah, I was going to answer your first post on the P15 by saying that one need only turn to reputable 3rd party (outside of the AH’s and ASR’s) technical reviews to gain information from.

My scale is loosely: mmmm mmm mm meh They then get categorized—just in my head—table, dinner parties at home, dinner out, Class A, Class AB, …

Don’t forget math, english, geography and history classes!! :grin: Best wishes

I am unable to address this, possessing insufficient knowledge, but understand the distinction you are making.

I think I’ve heard Paul say on numerous occasions that the PowerPlants aren’t perfect, nor are they presented as such. The requirements for audio, specifically the current requirements for amplifiers, are not well served by devices like lab supplies like the BK Precision offerings. One, the 9801 can…

[image] Barsley: You can’t argue out of one side of your mouth that the power supply of the device can handle filtering high frequency elements, and then argue the opposite. Who is the “you” you’re referring to here??? I never said anything about the BK, or about any opposite argument of audi…

@Barsley well said. Right to the point of why his tests are not as good as the ASR fan base assumes. Thanks.
