I have been using PS Audio regenerators for years. I currently have my entire system connected to a PS Audio P5 regenerator, with the exception of my two powered subwoofers. Even though the power I receive from the wall is relatively clean, (1.7% THD). After regeneration, the power my equipment is being fed has .1% THD. That is clean power. The cleaner the power you deliver to your system, the cleaner each component begins its job of contributing to your system's musical performance.
The P3, P5, P10 series was a huge performance jump for PS's regenerators. The previous model, the Premier Power Plant, although designed at PS's Colorado home was manufactured in China and reliability and therefore performance was problematic. Example. I plugged my entire system into my PPP and the power demand toasted the regenerator. PS Audio, being the customer service oriented company that it is, sent me a new PPP. That was fine, but I had to buy a Duet power conditioner for my power amp. so I wouldn't toast this PPP.
Knowing the problems with the PPP, PS set out to redesign their regenerators and that effort gave birth to the P3, P5, P10 line. They offered a generous upgrade stipend if you returned your PPP for one of the new models. That's how I came to have my P5. It is designed and built in Boulder, CO. It is built like, well, a tank! Even with my power amp. plugged in with the rest of my system I am only using 30% of its capability!
PS Audio has recently redesigned their line again. The P12, P15 and P20 are their current offerings.
Paul McGowan and Co. are a class outfit! If you would decide to got the PS route, Don't get any of their models that precede the P3,5,10.
I love the sound of my system with the P5 and it is staying put.
Another PS Audio user here, dual P10's in my case. I used a P300 back when PS Audio put out their first regenerator (late 90's), and I wasn't all that impressed (except by the waste heat - - wow did it get hot!). The P10 is entirely a different story, delivering reliable power while generating just a bit of heat itself. I agree with Elizabeth's general descriptions for the improvements to be had, but with the P10 I don't lose the bass output, even with my 300 watt ss Class A/B mono amps plugged in. I get a system that does not vary so much from midday to late night, etc., and with all of the clarity and "rightness" of music. I think they are well worthwhile.
@jbrrp1 Great point about the sound of the system not varying with time of day like it often does without regeneration! That was one of the main reasons I bought my first regenerator, the P500, years ago. You are right about the heat. It was tough to run in the summer.
Oner more point I failed mention about my P5. It does not restrict the dynamics of my system at all to run my 275 watt/ch. into 6 ohms SS amp off of it.
I'm listening right now to the Reference Recordings LP of Mike Garson's Oxnard Sessions Volume 2. Spectacularly dynamic, spacious, just lovely sound.
PPP that I use does not restrict dynamics and makes everything better, including the dynamics. The wall current here is terrible, unstable and very dirty. My amp is 120 Watt/Ch, the entire system is plugged in the Premier. Power cord from the wall to PPP is Custom Cord Company Top Gun.
@inna That's great!! I'm glad to hear that your PPP is working so well for you. You are probably experiencing a significant improvement as you state you have "very dirty" power. My incoming AC only has 1.7% THD. From what you are saying your THD would be significantly higher than that making your PPP a true godsend.
Incoming THD is 2.0% at best and usually worse. In the past two years I made four upgrades: 1. PPP - biggest improvement, 2. Purist Audio Neptune interconnects between phono stage and integrated amp - second biggest, 3. Purist Audio Dominus RevB Ferox power cord for the amp - third biggest. But all three were quite big. I also got Tchernov Reference MK II interconnects that I use from phono to tape deck when I run the system like that, which is often. In this case Purist goes between deck and amp. In fact, in my system this arrangement gives overall the best sound from vinyl.
Clean power, regardless of how you accomplish it is to me the largest factor in a musical system. Put another way, the further up the line you improve the signal the greater effect you have throughout the system. I use balanced power throughout and it's great. I'm sure the PS Audio is great at this also. Reproducing music with dirty power is a compromise throughout.
Aquired the most recent PS 15 Direcstream PowerPlant and repeat the previous messages. Just sounds better all the time. The newer 12, 15, and 20 are pricy but are more efficient, less heat, and bigger headroom. With that all said my guess is their are some good deals to be had on the recent "older" generation 3, 5, and 10 PowerPlants. I live in a condo complex with a lot of dirty power. THD is going from 3.0% to .1%.
I am so glad we have clean power in Australia: 240V +/- 2V and 50Hz +/- 1Hz.
In any case, I use a Monarchy Audio AC Regenerator for my line stage and to be absolutely honest, I can’t tell any difference with it in or out of my system. Having said that, the Regenerator absolutely bleached the sound of my 6W/channel SET power amp and equally dried out the sound of my Leben phono stage.
If you have "dirty" power then maybe, but for mine, power conditioning otherwise is a marketing beat up
Also, I thought quality components had quality power regulation as part of their circuitry?
I can’t praise Eaton Power Quality data Center UPS products highly enough. There is a marked difference between these on line double-conversion UPSs and substandard SOHO units. I use the Eaton Powerware 9130, which produces a pure, clean sine wave output, and can give detailed reports about utility power quality and of course load levels and runtime. The only downside is that these UPSs are fan cooled, and therefore cannot be used in the listening area. I have my units in the basement, freeding a sub panel that serves dedicated branch circuits to my system.
Well, that should probably be extremely high quality components when we have a current like that. I didn't try Gryphon or Lamm in my place, this would be interesting. Elizabeth, that's good to know. I think some turntable motors dislike changed frequency as well.
Interesting topic !! I jumped in higher end after 20 years of smaller experiments with audio gear. I am one who is using the latest PS audio P20 with the following gear: ARC preamp ref 6 ARC phonostage ref 3 ARC power amps 150se LINN Klimax DS LINN klimax turntable Sonus faber Amati
Before I hooked up the system with P20 all the above system was on Nordost platform which was QX4, QRT, QB and the Qkore. My cables are Nordost V2 and Odin2. I must say Elizabeth comments on tube amplifiers with regenerates is fully noted and its seem correct. I had notice able differences between the Nordost and P20 setup. I personally preferred the Nordost setup where the bass and tonabilty with soundstage was much better than the P20. I am surprised and it left me with a hole in my pocket. Over where I am residing in Asia there is no free testing period....only 1hr of listening the most. Anyway the P20 is still new with some 4hrs or so and the entire system is under 150hrs of operation since installed. It is definitely premature to gauge however this is my current predicament and assessment. I dont know what to expect and at the moment I am not sure which way to go. Confused.... any suggestions?
Hi I been reading all you guys responses. Im a retired mad scientist from many govt and reaearsch areas of expertise and also an audiophile and musician. Well im here to tell you all if you just buy a good big UPS battery supplied medical grade line voltage system your power will be a pure sinewave like you wont belive, its got to be a true sinewave not a cheap version unit. they dont cost as much as the stuff your talking about and we used them in Neclear reactors,MRIs and super critical analysis equipt all the time with excellent results. yes the incomming line is garbage especially with all the new switching PS oscillators noising things up. So you cant get purer power than a properly modulated DC source. I run a few 8D 12 volt batts X10 =120 volts and a Techron Gradient amplifier(Crown) for 10000 watts of pure power where i can tweek the 60hz up and down at will and avoid inductor phase shift . The E bag medical grade 5kwatt ubits are reasonable cost try it and see. pardon the typing I got parkinsns.
oh I also remembered that tripplite made some super units that you can monitor and control with your PC and they go cheap from the computer server world often just needing new battery banks. Sola alo make some nice simple units. The Techron way is just my wierd method of doing it,
I remember years ago someone here was talking about Phillips medical grade device he stole somewhere. He preferred it to everything else he tried and he tried just about everything. I'll keep this in mind, thank you, perhaps that's exactly what I should try next instead of upgrading the regenerator.
I have had a PS Audio P1000 since 03 and overall it has been a plus in my system. There is more of a bIack background and the midrange tonality is a little clearer. When the amp is plugged in to it the bass is a luttle leaner but more defined. I run it on 60 hz. I have had my amp oscillate. I guess you could call it. It would softly drone in and out on multiwave. It will blow a preamp fuse now and then. Usually when we have a split sec power disruption. I don't use clean sweep anymore after blowing fuses. Don't hook up anything with a motor to it. It is a bruiser. I used to hook up a 600 watt amp to it now and then and there no problems except heat. And I bigger power bill! Regenerated power is costly with a big amp plugged in. I couldn't tell any loss in dynamics. However smart people here have wrote that the amp would exceed the amps or amperage of the power plant. I can't remember. I disconnected it from my system 2-3 months ago and just used a power strip. At first I said huh no difference. So I listened for about 2 weeks then switched back. Ahhh there is a difference. I don't believe in quick AB testing. You really have to get to know the equipment and the equipment changes you make. I'm using my SACD player in just the filtered outlet and it sounds better to me. My system was sounding worse about 2 weeks ago. I made some changes and something corrected itself and now it sounds great and I don't want to touch it. In all honesty it could have been some dirty power coming down through the lines but thats what a power regenerator suppose to correct!!! Late night listening still sounds best. Must be something atmospheric I don't know.
Your fine running tube equipment, tape decks, turntables and electric trains for the matter on a PS Audio unit. Just don't put it on any of the wave options and keep it on 60 hz. About bad electricity. I downloaded one of the free apps for the measurement. I'm of electromagnetic radiation. It went way into the red placing it near a motorola walkie talkie. Same thing happened near a hairdryer. I got it to measure the electronic field on a tape head to see if. It needed demagnetized but couldn't find anything. All the ill effects of electricity is a new frontier. Imagine if used properly in a different way it could also heal!

I thank you all, and now specially to "hemigreg", who brings us a very important theme with several comprehensivenesses,
of great relevancein which I very much believe. But
I think that my solution, at this moment, involves
cost and practicality of application. An then I ask you :
Where can I find good audio stores in New York City, or others cities where I can find
trustworthy used AC regenerators ???
Im currently working with one of NYs prominent Brain Neuralogists on stimilation of serotonin,dopamine,norepiephrimn with magnetic and RF and audio signals modulated upon music that the patient "likes" and it proves to work with 73% double bling exp. im also using this to solve opoid addition by blocking the mu receptors like the drugs work. some major chemical details there that i wont getinto here. and lots of ion electrical excitation too. rememer every thing got a resonant freq(smile) got to love 432hsz. anyway A regenerator is really a fanceyIsolation transformer with extra filters on in and outs nothing more. sorry vendor!! read my link for audio physics for some good stuff. Look at your signal on a good scope. and nightime is when the line wave gets a bit cleaner cause most of the noise inducing motors and swithced supplies and not getting used. do the math, the inducatance also of old light bulbs tungsten -used to filter out some high freq line noise but with all the CFL and LED bulbs they are no longer in your house to be unintended RF filters/bypass loads. I get into it on a regular basis with my local utility for the heck of it about all their "noise" even though i got it filtered-its just fun to be a pain in the butt for them and keep them honest
I have, but they were early ones in 90s. sorry for not updating my tear downs in 25 years. Im betting they are similar to the VFDs inverters starting with rectified filtered DC sourceed from isolated ac input. but prove me wrong and post the schematic if its not pripotary. ill build one for cheap. some 2n3055s are always good. I need a good physics discussion with a PHd in DC ion fields please PM me for an offline talk. thanks
Sorry if you think I'm angry. It's a matter of haste. All contribuitions are wellcome. But somethimes the discussion goes so far from the topics that the objectivity is lost. If you observe, this is the third time I ask about. And I need a consistent feedback for an eventual decision, nothing more.
"Like anything audio, the cost is not equal to the improvement" - - so true, Elizabeth! You have to have been born with a pretty funny itch in your brain to spend like we do, but who's to judge what brings joy to one's soul?
I was an early adopter of the PS Audio P300 and ended up with two of them because they made an astonishing sonic improvement in my source gear and preamp.. But they couldn't handle any power amp I owned (I know, these are supposed to sound better into the wall).
I have a TON of source gear -- 2 turntables, 3 R2R decks, CD/SACD player with separate tubed PS, cassette deck, tuner --and now have both a P10 and P5. I tried the power amps (845 SET monoblocks) directly into the wall for comparison. Nope. Sound better to me into the regenerators. I wouldn't be without them. Plus you get superb service and support from PSAudio.
If you want to be battery powered, and truly off the grid, Stromtank is another option for a regenerator, if you have deep pockets.
I feel regenerators make theoretical sense, but in actual practice, are flawed. Firstly, the DC to AC conversion induces noise. Secondly, they usually do not deal with the noise generated by the devices. And the list goes on...
@vtvmtodvm The P5 display window shows the amount of incoming THD and outgoing. It tells you what percentage of the P5's capability you are using as well. In that way you can tell if you are unduly taxing the unit. In my case I appear to be in good shape as I am using only 30%. By pushing once on the display's touchscreen you can see the incoming sine wave, push again for a visual display of incoming distortion on that wave and one more tap gets you the outgoing sine wave.
Paul McGowan has been a believer in power regeneration for a very long time. It just took time to develop the technology to the point where it is now. It's been an interesting journey for those of us who've been riding that train for some time!
