The Power Plant Regenerator debate drags on


I have seen a lot of videos on this topic and read a lot of threads. Do AC regenerators work -- in the sense of actually contributing to the improvement of a system's sound? This, of course, assumes there is a problem to fix, but if there is, it's an interesting question.

I know ASR did a couple videos about the PS Audio Powerplant in 2022 and there was a lot of discussion around that time.

It was surprising to see Paul McGowan raise the issue just a month ago (Dec. 2024) on his channel, here: https://youtu.be/wAywgassj1Q?si=6PqP7Y1jP2IebxE1

It's a pretty predictable "objective measurements" vs. "subjective listening" issue, but there is some discussion of placebo effects in Paul's reply.

Anyway, possibly of interest. Or not. Just weird to see it come up again after a couple years.

Definitey a YMMV product.

The BEST audiophool $700 I spent was on a used, MIC Power Plant Premier about 8 years ago? 

Sent it back to PS Audio 4 years ago and it should be good for somewhere between 5-10 years?

PP should be in your own setup to see if it does/doesn't do what it's designed to do. I don't hear any negative SQ even with a tube amp plugged in.

The SQ "improvement" is subtle. Plugging in the TV it's noticeable but NOT dramatic-richer color and sharper image quality.

I'd get another PPP,  but PS Audio no longer supports it for repair.

+1 Definitely ignore anything from ASR. I completely agree. 

Honestly, I take most of what Paul says with a grain of salt. He really likes to listen to himself talk. 

I have been in this pursuit for fifty years. I remember when the first regenerators came out. I thought if they were god's gift to the high end audio world, they would take the pursuit by storm. They have not. I have read with interest accounts of their use for decades. It seems to me they achieve the same kind of results you may get with a good power conditioner... perhaps at a higher price. I know folks that have got them and quickly moved on... they improved the sound, but a good power conditioner did more. A couple folks kept them. 

So, I'm reading this string in case some folks provide some specifics Cause, the jury still seems out to me. Probably in some specific cases they are the perfect solution. 

@ghdprentice    I wholly agree with everything you said.  Before I moved into my current home, I had stable power (voltage and distortion) and a good power conditioner was all that I needed.  New home, different story.

So, I would put out there that:

If you have crappy power, then something along the regenerator type technology, whether PS Audio or someone else's, COULD be a solution and is worth exploring.

 

 

 

Every neighborhood has crappy power.  (I work for a very large utility).  

Why?  because most appliances don't care.  It really doesn't matter to most all appliances how crappy the power is. 

 Most power is generated by rotating generators driven by steam from gas, nuclear, or coal.  More and more power is generated by wind or solar.  The traditional power is generated as a pure sine wave and the large rotating mass is synchronized to the grid, not only providing great quality generation but adding important stability to the grid. 

Solar and wind are just the opposite and have to be converted to 60 cycles and fed into the grid.  this makes it harder to generate perfect power and makes the grid less stable.  But that isn't really the biggest problem.  Loads come in all different forms from motors to resistors (toasters, hair dryers, etc) to large asynchronous industrial loads.  These loads distort the shape of the electrical signal.  

So it doesn't matter if you live in an old neighborhood or a new neighborhood, it is all the same.

And a transformer doesn't change it.  If it did, we wouldn't want to send music through a transformer, would we.

there is no "if" you have crappy power, you do.
