PS Audio Stellar PowerPlant 3 Power Regenerator Review 

Quick Update: When I first got my Powerplant, I was using it stock just the way wave did and boy was I missing out. I ordered the thickest power cable for lower resistance and also a high end synergistic fuse and to my surprise, It completely transformed my whole system in the best ways possible. Even more detail was revealed in all parts of the frequency. Didn't think these tweaks would make such a drastic improvement.

Hi Randy it's funny, I also have a PP3 Plant and audio gd DAC combos. First an R-28 w/o regenerated PS and now an even better R-27RE with the regenerated power supply coming from their R-8HE DAC (less expensive than R-27HE). I'm satisfied with both PP3 (fully in line with this review conclusions) and audio-gd devices and - especially for audio-gd - their excellent price / musical performance ratio (I really don't care about they measure not so well as we don't hear measures but music !). Btw both PS Audio (Paul) and audio-gd (Kingwa) managers are great people and both strongly believe on the importance of power supply's quality. What seems to be true IMHO. Gratings from France !

@@stephanespohr886 I agree 100%. I own the r8, di20, and the m9. All of which is connected to the power plant. Clean power really makes a difference in audio-gd products.

Amir tested the PS audio power plant and listened to it and as expected there was no difference whatsoever. Just spend the money on better speakers and not products that fix something that was never a problem in the first place

@@juliangst Amir didn't even LISTEN TO HIS CHAIN with the power plant connected! He literally just used measurements to come to those conclusions...

@@johenkay1129 he did 2 videos on this topic and explained why it doesn’t make a difference. Listening tests always come with bias and placebo effect

@@juliangst Your claim that "Amir tested the PS audio power plant and LISTENED to it" is false. How can you go off of someone who doesn't use his HEARING for AUDIO?

@@johenkay1129 he does

lol, what about the wires in the wall, your breaker panel, service drop etc... That's all the mystical, audio impedance fairy too.

They don't need to make a difference to the sound. It's a plug in religion!

@@MrsZambezi Religion is the proper term here. Gear like this is like tithe for the worshippers of the audiophile "gods". just imagine the soundstage one would get with a 30,000 USD power cable hooked up to this..

People buy snake oil every day. The expression "snake oil" is very old. We already know these things don't work. Testing has showed that.

@@Heinrich_Von_Schnellfahrer Snaildriver: ...do you drink water from a tap, a bottle or your toilet? It's a serious question

@@vicweast "It's a serious question"; no, It isn`t.

they are shite........

I have never heard the fan noise in either my P3 or P12. My music room has a very low noise floor.

@@martinwtaylor Thank You Martin.

Hi, don't worry for sure you won't hear any fan noise as there is no fan built in it (I'm myself owner of this PP3) 🙂 And also satisfied with it. Btw, nice review !

It's been a minute... I think I just cycled the master power switch on the back. Good luck!

@@wavetheorysound thanks, I tried that with no luck. I think / hope it is a fuse

It was a fuse

@@tghicks20 Good! Glad that's all it is.

Stick it in the bin instead.

Be honest. You don't really hear a difference. Own up.

@@MrsZambezi I doubled down, I bought a more expensive power conditioner.

@@johenkay1129 Unfortunately you wasted your money, because power conditioners can have no effect on sound quality. Still, it's your money.

@@MrsZambezi It definitely affected the sound. Sounds better than ever.

@@johenkay1129 Not possible. You're imagining it.

Ever notice the people claiming it does are the ones who bent over and WANT to hear a difference to justify wasting their money? Don't forget your power cord too. Never mind the 100's of feet of wire in the wall going to said power cord.

@@inothome a high grade power cord is not about the thousands of feet of wire before it: 1- be of enough gauge that no variations of power demand will alter its transmission to the amp, 2- act as an antenna to receive and send to ground spurious signals: that is it has not 3 wires, but 4, the 4th one is also connected to ground but only on the wall side. And yes, there is a difference.that can be heard given the right system and circumstances. On my system, probably not, I live in a small apartment and can't play it loud enough to matter.

@@grandrapids57 Exactly my point, what is "shielding" the wires in the wall and stopping them from being an antenna? Not that your electrical wires / cord are going to pick up any signals that should effect any quality piece of equipment to begin with. But, if your audio equipment was that crappy and somehow the noise on your AC line made it in to the audio output, then time to rethink the equipment you are buying. The last 2 feet of cord isn't going to make a difference. As far as power delivered, again, having even a #10 gauge, two foot power cord does nothing if the sockets are fed from #14 or #12 and are 60 feet long to the breaker.

@@inothome High grade cables are #14 or #12 and larger, naturally. . As for the wires in the wall, there is nothing, or very little going from the street to your wall plug where the stereo is that produces RFI (or maybe today's higher frequencies RFI is out of date?) It is the highly local area near the stereo with multiple items that causes it. I think much younger people today are so used to everything in general having such low RFI leakage, I am sure they never had to move a radio or TV away from a video game, a microwave or a TRS 80 Model I,, So today RFI is regulated as being so low, its now a foreign concept. Of course it is there and the 4th wire collects it and shunts it to ground. How much you have is dependent solely on you, your wiring and your equipment. You will have no RFI coming from down the street or from the bathroom clock-radio, but you will have it from all the appliances that are within a few feet of your system. As for the other points, it is the engineer's folly to use the 1st principles of physics and believe one can know without testing it: if that was the case, there would be no use for modeling or experimentation.

@@grandrapids57 There is plenty of RFI everywhere! Ever hook up a scope and make a loop of wire? All sorts of electromagnetic fields everywhere and yes, some in the audible range as well. If there is something near your audio equipment causing actual audio interference in your gear, it wouldn't be coming through the power cord. If it actually is, the audio gear has sub-standard power supply filtering inside and you need to get your money back. But a power cord or "regenerator" is not going to physically make your audio better. Physiologically, it may but physically quantifiable better, no. There's plenty of reviews on these things with actual data that proves it. The comment below this one sums is up well, "A fool and his money were parted".

I don't think so. Been awhile but I don't remember a fan at all

They are essentially silent -- some PPs have fans, but they do not run at audible speeds

My experience does not agree with your content-less criticism. Instead of making a serious claim ("absolutely useless") try actual statements we can understand and validate. In contrast, you didn't say anything except: "Trust me it's no good"). No, I don't trust you. I do know what my experience is with these devices. All I can say is that there is no detectable noise in my system since using this,I got close with quality cables and good gear but this was the last thing I had to do to get great sound without noise at low-volume.

That post has less creditability that what it purports to critique - the writer hasn't even tried one out although he has seen the testimony, such as it is, of people who have, and with no experience himself, dismisses those who have. Besides, there is much in audio that cannot be measured with today's tech or if it is measurable it is done only with a huge effort. For example, find a meter and play a recording into it, that will, like a conductor, be able to tell which violinist's instrument is out of tune or which member of the orchestra is playing staccato, measure how far the singer's mouth is from the microphone, or which will measure and place the 3d placement of instruments in a 2 channel recording. Instruments measure what they measure, but they are not a trained brain.

I see comments against my advice. So I will make the message stronger. These devices will make everything worse, not better…particularly if you use them in front of a power amp. This comes not from some random guess, but from observing controlled tests that prove it. Snake oil sells only to the ignorant. The marketeers depend upon you being ignorant. Check out the several reviews by independent audiosciencereview and you will see that such devices do nothing of any value, and can reasonably be expected to make things worse. Or you could just think. Do you REALLY expect a high end DAC, amp or other device manufacturer would allow their product to be susceptible to power line noise? It’s an invented nonsense problem looking for snake oil susceptible suckers with deep pocketbooks.

@@plcamp1 Well taken, but if such a device can make the 60hz, 120v power, with whatever impedance, worse going out than what's coming into it, it certainly stands to reason that such a device could stand to improve it, and likely an engineered device for that job, does do that job. Although whether such a device's regeneration can make worse or improve the audio quality of an amp is not a question I am addressing here.

It's only ever mumbo jumbo if you're too stupid to understand it. Is chemistry mumbo jumbo, or are chemists full of shit? Is physics mumbo jumbo, or are physicists full of shit? You can't have it both ways.

Tough. Enjoy your boring life

Hit the road Jack and don't come back no more no more
