Power regenerators X Power Conditioners

What a difference does make the use of regenerators ( for example PS AUDIO) instead of Power  conditioners. Is it really a good upgrade to the system?
Who has the experience?

I have a rather long history with PS Audio regenerators. The first, a P600, provided clean power but also functioned as a space heater due to inefficiency. A few years hence, PS had an engineering breakthrough allowing them to produce a regenerator (the Premier Power Plant) that ran much cooler due to increased efficiency and in a smaller case to boot.  During the use of both of these earlier units, I could not run my power amplifier off them.  They just couldn't handle that demand.  Indeed, with my first PPP I did run my amp off it until the regenerator failed.  After contacting PS, they sent me a new PPP but I now ran my Power amp off a PS Audio duet conditioner.

When I became aware of PS's trade-up program, I traded in my 2nd PPP for a P5 which is in current production.  Important point:I had a few conversations with the tech. guys at PS prior to the P5 upgrade purchase.  It became apparent, that there were numerous PPP failures and they were recommending all PPP users to upgrade to the P series.  Why?  Robustness of design and construction.  PS had enough of a failure rate with the Chinese manufactured PPP that manufacturing for the new "P Series" had been moved to the PS's home in Boulder, CO.

I was assured that the P5 could easily handle my entire system with room to spare.  Sure enough, I am using 34% of its capability with my amps and rest of system plugged in!  It is coasting along and sounds like it as there is no detectable dynamic constriction,( an argument often cited against regenerators).  Having the amp on regenerated power opens up the soundspace and provides great ebb and flow and clean sound...play your favorite jazz recording with well recorded cymbals.  They sound brassy and you can detect whether the sticks are wood or plastic tipped.  Same analysis can be done with guitar if you prefer.

If you are considering a PS regenerator, call PS and talk to their tech staff.  They will answer any questions you pose.  Another thing, go to the PS site to this link:  https://www.psaudio.com/ask-paul/   You can watch Paul McGowan's daily videos where he answer questions on all topics audio.  Lots to learn there.

Hope this helps!  Sorry this got so long.  One more thing.  Distortion coming into the P5 from my electric utility 2.4%THD.  Power output from P5 after regeneration .1% THD.
I own both a regenerator, and a transformer based power conditioner.
The main thing to understand about a 'regenerator' is that the regenorator is basically a fixed frequency output AMPLIFIER.
A regenerator is making 'new' 60 cycle AC power.
So using it definitely will increase the power costs to run the system.
(stay away from used PS Audio PPP they are prone to suck)

One other point is the new AC output of a regenerator is not perfect. yes it is better, but not perfect. Also a regenerator should not be pushed to deliver more than 50% of it's rated capacity.

The other type is a transformer based, Usually a big expensive toroid.
I use a Furman REF20i as my main power conditioner.
I also picked up a used PS Audio P-600 I like mainly for the fact I can alter the AC output to a different frequency than 60Hz.
I use it just on a few digital components at 110Hz .. so mine runs pretty cool.

Either type is fine to use. Some folks like one or the other.
Then a new type, the AQ Niagra 1000, 5000, and 7000 seems to use a different approach. (of which I know nothing)
I have used a PurePower 1050 AC regenerator from years back with great results, however dealing with the Canadian Company has issues.

Now I use Chang LightSpeed AC line filters that work just as good, and are cheaper, but hard to find.

Both did not limit input current flow.

Run my entire system off either one.
Simple answer - yes. Power conditioners and regenerators can truly benefit any system. The magic comes from experimentation. Don’t be afraid to use more than one. Learn about the different types of distortion on both your incoming ac power and that emitted by your own equipment, and how they interact to influence the lack of purity in your sound. A huge number of recording studios and professionals, including countless bands seeking the best sound they can obtain for their super expensive and often super profitable gigs, use Equitech products. Likewise huge numbers of clubs and dance halls.  Worth you looking into. 

What about the sound results experience? Before and after P5.

@sacresta  I opined above.

Your opinion was the best untill now.
Thanks so much!

Thanks so much!
Thanks a lot hemigreg!!!!
Do you know how does it wheight ?

ive got some that are 128lbs, the batts are the weight.
some units are 40lbs rack-with batts external on floor.
there are many desktop units 1 kw 25lbs or less

It is important. 
thanks a lot one more time.

Does these devices show the THD in the input and the output?

thats a mixed question as the THD is usually a result of interaction with a particular load-so it cant really be told unless you specify your phase leads/lags etc...
The IGBT units are the best at fitting the general specs. like 3rd order harmoinics which are common in audio stuff. but thats a vauge guess.
i would consider running my crown THD unit but its too valuble to me to start putting it on line level stuff. even though ive had it on my techrons 10ks but in a special enviroment.
you have to really measure your power phase in on idle and full load and calculate the shift necessary. I can come up with an awsome value at idle to advertise and impress you but it will be a trick..
if you run it on the battery it will be = to zero.
[ hemigreg ]buy a used commercial UPS for 800 and have better power quality than any "regen" unit cause thats what they are without the battery.


I presume you're using the filter provided by the UPS, is that correct?
If so, why not just buy a power filter?

That is, my understanding is that the UPS generates AC from DC if/when: (1) there's a loss of power (from the wall) (2) there's a battery in the unit. Otherwise, the UPS simply filters the AC coming from the wall and keeps the batteries charged.

So, no battery equals no DC, hence no generation of AC from the UPS.
Is that not correct?

I just spoke with the technical support folks at APC and learned that their SRT line (e.g, SRT 3000 XLA) will convert AC to DC, and regenerate AC (pure sinewave) from DC even without a battery.
