has anyone ran a comparison of the signal on a real digital scope vs what the unit is telling you?? The units that i had seen calculated THD and the sinewave for the readout with software but did not actually measure said aspects live online.I know this because i have scopes and THD analyzers on line at all times. ps Just bought another THD unit today. the frequency chop in the AC oscillator part has shown noisier than that output of a good UPS and a IGBT AC drive. too many high order harmonics. again I say run your stuff on DC battery power and compare. just about every componet converts the AC plug into dc later anyway, this is the next phase of top line audio equipt. Hint-the military does this for many critical instruments and not for fear of loosing power. For finite noiseless signals and NO ground loops ever.
@hifiman5 —Oh, OK; thanks. Actually, I was wondering what anybody who owned a harmonic distortion analyzer would be doing on a forum site such as this one—but that's a whole 'nother can of beans. Amen.
I did try the P10 with a 30 day return option, and it stayed in my system. I will likely also demo the P20, given the word of mouth from others that have upgraded on this path. I can hear for myself and decide if it improves things and if it is worth the scratch.
PS Audio is actually quite good about promoting home trials to make sure you like what you are buying.
By using 50% or over will increase all harmonics and output stability, see design specs used for all critical power systems. it can be shown in the math-do it and see, thats why Mil spec calls for 3 times rated load capacity. use that for your feed and enjoy improved power signal
Also please use Power Factor correction Caps on your Listening area power ,cause all the X formers cause a bad phase shift in input voltage otherwise. a few 100 mfd caps across 120v line for every 1000watts is good. or go to 3 phase as Vrms beats the .707 instantenuous value
my point is that there are tried and true standard ways of fixing up all your power problems and therefore your resultant sound without giving into the marketing hype of regerative sales at like 1/4 the cost. IE- pro studio recording desgns. Heck just going to balanced/isolated ground inputs can bring noise floor up 10 fold at little cost. to you.
PS Audio is a great customer-focused company, and their regenerators are a good investment. I use different models on my three systems (home office, AV, and high-end audio. I am delighted.
With respect to all of the posts before mine, I'll try not to restate other observations. I started with a P300 for my 2 channel system and then purchased a Power Plant Premier for my home theater system. The howl it made trying to handle a plasma TV drove me crazy especially considering that the PS Audio tech staff said there was nothing wrong with it. Finally I was able to get a response from Paul McGowan who admitted that the PPP was not able to properly handle the load from a plasma TV. I then bought a Pure Power regenerator (made in Ontario Canada) that handled the home theater system with ease so I bought another one for my 2 channel system. Turned out that my tube equipment did not care for the class D based product and started to make uncontrollable squealing noises. I then fell under Paul's spell again and bought a P10. You should remember that sinewave is the only safe mode for tube equipment and it basically is an amp so the better the power cord, the better the sound.
Tubes work best on pure DC!! the electrons and such know their valance bands and holes to jump or get pushed into amplifying fronm the filiment source. LOL. AC is just a more convient source of power in the home now. Ok OK the motors may need 60hz Synch but nowadays most all run DC PWM anyway. the physist in me had to let loose on you. sorry.

switching power supplies dont like driving other swithcing PS cause the load changes inductance and capacitance so much depending on the varing Load. they like constant impeadances like a load resistor across the output.. like driving difficult computer systems. well known in the Server world look at the huge inductors on the main feedsw to smooth out the ride.
I have used PS Audio Products since the 1980's so, yes, I drank the koolaid. That said it is a wonderful company. I currently own the P-10, a P-5 and a P-3. Like others my P-10 runs everything on my system except the subs. The sound is cleaner, blacker and more detailed. One benefit of power gen that is not often mentioned is the significant improvement to the picture quality to my big screen TV. PS Audio recently upgraded all their models, so you might find a good deal on a used P-10 or P-5. If you want a good deal on a new model visit https://www.underwoodhifi.com/products/ps-audio. Good Luck
Holy cow!!! that things expensive.... You guys got too much free $$$$. a pure sinewave UPS with an external THD and scope digital analyzer and protection from loss of power is like 1/2 that cost. the many utility transformers and line losses are irrelevent to your final load after the UPS also with better than 1 volt regulation. and you can run 5-7000 watts not only 2000. IM in the wrong business... LOL. If a digital bigscreen is improving from a line feed correction something else is wrong with your system. sorry. maybe if things were still analog you would have a excuse. I say do as you with its your money.. the intergrated scope and analyzer is calibrated to whos and what standards- NIST-MIl Std. with what traceability????
My PPP also was a problem with my Plasma. The PPP fan would turn on full blast, and even if the Plasma got turned off, the fan never shut off, Until I turned the PPP off. back it the fan would remain silent, Until the next time. I sold it.
@sacresta ... you mentioned NYC in one of your earlier posts in this thread. If you’re located here (as I am) — or in any urban environment — then I think your interest in a regenerator is especially warranted. I’m in Brooklyn with sometimes OK AC and oftentimes awful AC. I started with a PS Audio P3 and now have a P5.
I noticed the benefit of regeneration immediately, but it took upgrading to realize what I had. After removing the P3 from my system, and while waiting for the P5, I remember struggling to listen to my system at all ... it just wasn’t all that pleasurable after experiencing my system on regenerated power. It was frustratingly variable and usually struck me as harsh and unfocused. Getting regenerated power back in my system was a huge relief.
Overall, PS Audio was/is a dream to deal with, and you may find a unit in the P3/P5/P10 series or the newer P12/P15/P20 series to be indispensable.
PS Audio...that’s it. By now you should find some nice deals on used P5/P10 units. Don’t hesitate, when it comes to clean power PS Audio is the way to go. After I’ve tried the P5 "I couldn’t live" anymore without a regenerator. Not to mention their customer service, it's one of the most effective and proactive I've encountered in this business. In my book that counts. A lot.
Im not familiar with these newest models, I know the early ones did not offer anything i am asking about these $5000 units. what is the claimed output distortion under continuous full load? can they drive 5000 watts on a continuous basis without running hot? what does it do during a momentary power glitch? can you program all the operational parameters?
PS Audio isn't the only game in town. Purepower makes very good regenerators with battery back-up.
I use a Purepower 1500+ which is excellent. The only concern is their customer service isn't the best, but the units are reliable. Had mine for about 6 years with no problems.
I run all my equipment on it, even the amps with no loss of dynamics.
