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.
PS Audio PowerPlant 12 Review (AC Regenerator)
This is interesting. The testing concludes that the filtering inside of the actual electronics device is what matters and that this PS Audio product actually adds its own noise. Some irony.
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 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. |
djones, silly analogy; not applicable at all. With respect, you seem to always be so hell bent on sticking to the objectivist mantra that you miss the bigger point. The audiophile pursuit, and obviously music, is first and foremost about listening; measurements always take a back seat. That is the reason that the review is incomplete. Important to remember that there is as much vested interest for the naysayer to NOT hear a difference in sound as there is for the delusional to hear it; whether there is actually a difference or not. Of course, if the listener can’t hear then all bets are off. |
Well, perhaps it’s not a very good analog. How about, ths thing could no more change the sound of an amplifier than change the resolution of your OLED TV. I agree the first and foremost pursuit is listening, I disagree that measurements take a back seat but are paramount in understanding the equipment I use to achieve this pursuit. It tells much more than some random flowery prose about lifted veils and darker blacks. What I don’t get is those hell bent on subjective opinions opineing how hearing with your ears is the summit while never really trusting their ears without using their eyes as well. Of course if you can’t really hear without sight ....
Edit: Yeah, it is supposed to new and improve my TV as well. |
