PS Audio PowerPlant 12 Review (AC Regenerator)

frogman - I'm sure it has good PRAT. 😉

PS Audio wasn’t given an opportunity to respond.

I agree with this point. I have reached out to Paul McGowan so if he wasn't aware of PowerPlant 12 being measured and the resulting discussions on audio forums, he is now. 

Here is part 2 of the testing.  

PS Audio P12 Review Part 2: Power Testing

And here is copy and paste of Amir's conclusion. 

Conclusions
It is clear from the above tests that using the P12 degrades available power to an amplifier, not increase it. Both continues and dynamic power are limited, as they should. You are inserting another cable and box (power regenerator) which has its own losses. Burst capability in power amps is provided by its internal power supply capacitors that have a very low impedance path to the amp being inside it. Trying to do that with AC is like pulling the end of a wet noodle and expecting the other side to move with it.

The data here is the reason a number of power amp manufacturers recommend to power their units directly from the wall and not through a AC regenerator. You want the least impedance path to the AC outlet and that is a simple power cord.

While with low current devices we could hardly find a harm caused by the PS Audio P12 (other than to your bank account), with power amps we are seeing a distinct degradation of power. In this regard, I think any marketing material without proper objective back up to the contrary is irresponsible here. Please heed the advice from me and many amp designers that you don't want to use these regenerators for power amplifiers.
 

It tells much more than some random flowery prose about lifted veils and darker blacks.

But my wife heard it from the other room!!
