Is PS Audio the only game in town for Power Regenerators?


I was curious if there are any other manufactures of  Power Regenerators for audio other than PS Audio? 

I am seeing ProPower come up in searches , but not much else. Anyone with any experience with other brand Power Regenerators that also had PS Audio for comparisons?

I have a P12, P15 and P20 I like them,  but this 3000VA UPS which I own too, is not that far off any of them under an oscilloscope.. I do not know if the PSs are worth the additional cost.

All what I say is my experience, so I do not say if a product is better or not. 😊

In my home in the USA, the entire house was rewired when Covid-19 started because I needed very clean power for my instruments. So half of the house is in one panel the other in another. From the “lab” panel I have 2 5000va Apc and a 3000va connected, from the ups the 3000 and one 5000va go to the “lab” the other 5000 goes to the living-audio-room.

What comes out of the ups is in the 0.2thd and 119-120v, but not true/perfect sine but very very close despite the claim. So I tried an Isotek to lower the noise, which marginally did until the outlets rusted. My house is also temperature and humidity controlled, because for the work I do I need very stable environment to make sure that I have as little variation in my projects, so the Isotek rusted because cheap component in the plugs.

Then, I bought a PS15, and lowered the noise and gave me a very close, closer than the APC, sine wave, and 0.1thd. Did the sound benefited from the PS15? Yes but not enough, then I bought a p20 because I read that they are better.

in my system the P15 and P20 sound identical, maybe because my system does not load them much.

I called PS Audio and asked them if me running the PS from my 5000va Apc was a problem, they said no, but in the documentation it say do not do it. So I ran a 20Amp outlet and plugged the PS20 to it and there was absolutely no difference, in the output power metrics, the P20 was working harder but not sound difference.

the panel had ~1.9thd and the voltage fluctuation was around 6-7V, and radder jagged sine wave.

Are the PS worth it? It all depends if they make a difference in your system and you can hear it.

If you are in a budget, put a 2000-3000va UPS, there are many good brands, then see if you like the improvements, if you do then you can try the PS.

 

Take a look at these 2 videos and you will see why PS Audio is not any game when it comes to power conditioning.

I did the same measurements in my PS 15 and 20s

They are electrical junk
