People are being deceived and are unaware that what they are receiving is deceptive information designed to make them react to the deceiver's wishes.

so should the power plant be plugged into a power conditioner to have the cleanest power + the most stable and lowest impedance output?

[@user-od9iz9cv1w]

Interesting discussion. Thanks for sharing it. Some sceptics may try to say Paul's answer is self serving. My only reference is an audio buddy whose ear I trust swears by the improvement in sound from his system resulting from the PS Audio Power Plant. Myself, I have experimented with DIY power filters and absolutely decided that any type of inductor or ferrite bead reduces dynamics and that an isolation transformer does the same. I do use a DC blocking circuit, an MOV to block spikes and some low value caps to filter out high frequency noise. To me those combined with DIY power cords make a significant improvement. My bet is the power plant is best.

[@JonAnderhub]

Sorry but your friend is being fooled by his lighter wallet. If you look at most devices they will be rated from 110 to 120 volts and from 50 to 60 Hz. The fact of the matter is that regardless of what A.C. power is coming into any device the first thing the power hits is a power regulator consisting of an isolation transformer and caps to store the A.C. for conversion to D.C. usually through diodes to power the device. No conditioning of the A.C. will change this process or change the "sound" output of the device.

I've tried a Power Plant 5 and Power Plant 12, both sounded inferior to the similarly priced IsoTek Titan and Audioquest Niagra 5000 power conditioners.

[@LeonFleisherFan]

While the sonic benefits depend on the system used, the most noticeable is that conditioners, filters, DC blockers, isolation transformer etc. tend to either compress dynamics or, at their best, get rid of noise or hum without negative side effects, whereas a regenerator is going to have a positive effect dynamics (or none). Blind testing, the consensus has been that one sounds bigger and more powerful than the other (there's not measurable difference in SPL - I always make sure to match levels making comparisons, and so far, there's been no need to so here). Other differences (e.g. soundstage, a sense of forwardness etc.) seem to depend on the individual listener and of course the system. My recommendation is to arrange a demo in one's own before jumping to conclusions. While I haven't yet heard a regenerator have a negative impact on the sound of a system (provided it's oversized, which it should be, especially if used with an amplifier), the improvement may be negligible and irrelevant, and as mentioned before, there may be both pros and cons using conditioners, filters, a DC blocker or isolation transformer (I've heard e.g. a DC blocker get rid of hum, but the sound of the system got so much worse, it wasn't worth using). Besides, the same amount of money may be better invested elsewhere in a system, in fact, I'd go so far as to say this is true of most systems I have heard.

Amir from Digital Science Reviews is a critic on the topic of power regeneration.

Paul......I have a Fifth-order Harmonic noise (I believe courtesy of a sub-station or pole transformer outside) causing problems and buzzing in my preamp/amps .

Couple of weeks ago I discovered PS Audio were having a crazy sale on the P12 Power Plant. I have long wanted to try one out.

Time by Pink Floyd, the chimes going off always seemed a bit muddy. So much going on but now everything sounds distinct. The best way I can describe the improvement of my system I was very happy with to begin. It’s like so much more came forward in the mix of songs. If I’d never connected a power plant I would never have thought about it but once you do, goodness! Bass is freakin amazing It says the harmonic distortion is 6-7%. Must be a lot as it’s near the meter limit. The incoming sine wave also looks copped off. I have a meaty Cambridge Audio Edge A amp driving Elac Adantes but the P12 tells me I’m drawing a steady 200W with occasional rises to c300W, way below the P12’s limit. I watched Audio Science Review on the P12 but was always going to try it. Some people accuse Paul of snake oil. What kind of snake oil salesman offers a trial at home and will even pay return shipping if not happy?!! The engineering debate is way above my head.

Actually what Paul said was very deceptive and he avoided the fact that ASR did much more than just test the SNR.

But then, ASR pointed out the fact that the Power Plant or any other power device couldn't possibly have any effect on a piece of audio equipment because all audio devices (DACs, Turntables, Streaming devices, or even amplifiers) have their own built-in power regulators that isolate the A.C. from the component AND audio devices don't use A.C. the A.C. is converted to D.C. so there is no possible way for an A.C. conditioning device to have an effect on the performance of the audio component. As far as transient effects, that is purely the function of the capacitors within the audio device's power supply not anything outside of the device as long as the A.C. is within the device operating parameters (typically 110 V to 120 V, 50 to 60 Hz).

@@sudd3660 My post was meant to convey some amusement at the fact that PS Audio chose this particular question to respond to, make a video about, and title: “Are Power Plants Worth it” . This is amusing to me because the answer is entirely predictable given that they make the product, and therefore it literally goes without saying from their perspective. However, I would add that PS Audio may have done themselves a disservice by phrasing the question in this particular way. Why? Because there is no debate whether the product “works” . As you point out- It does. But the specific rhetorical question they posed: “Are Power Plants iworth it?” is entirely another matter. As you will see from some of the other comments, several people cast doubt on whether it is, indeed, worth its several thousand dollar price tag. Therefore, my amusement is compounded by the fact that they have succeeded in answering a question that need not be asked, while simultaneously inviting debate on the questionable value proposition of the product in question.

@0:53 "Amir is a good guy". Paul, that good guy is a cable misinformation spreader. Amir tells his viewers that cables do not affect sound quality; that it is a scam. Putting the word "science" in the name of his channel, does not make him a scientist. Amir is not a scientist. That is a red flag, just like someone calling their channel a doctor's channel, when they are not a doctor. Amir is a guy that impresses people with his testing equipment, and his shop talk, just as a used car salesman can impress people that know little or nothing about cars. Amir uses his channel to feed audio trolls what they want to hear. Amir will not sit down in your listening room (or anyone else's similar listening room), to test the cables that he bashes. I have challenged him to do so, and he refused. A scientist will confirm their tests with an actual listening session, using the proper lab equipment. And a room, with professionally set-up FR30 speakers, is the lab that Amir refuses to include in his testing. Paul, as hard as you work to impart audio knowledge and improve sound quality in all areas of music recording and reproduction, people like Amir cut you off at the knees. Perhaps you were not aware of how he operates, such that you called him a "good guy".

[@JonAnderhub]

Amir not only has a degree in electrical engineering but has had a very impressive career, including being a vice president at Microsoft. Amir's testing methods are very valid a repeatable by anyone doing testing and more importantly Amir is open to any valid testing methods or evidence that doesn't agree with his conclusions. Amir does, in fact, use proper testing equipment, and explains what equipment he uses, and how his test is performed, so that anyone can duplicate his testing or dispute his conclusions based on legitimate testing methods of their own. Additionally, Amir does perform "listening tests" as well. If you actually paid attention to Amir's testing, you would see that Amir never sets out to disprove any manufactures claims and has some very positive tests and conclusions about some audio equipment.

[@NoEgg4u]

@@JonAnderhub "Amir not only has a degree in electrical engineering but has had a very impressive career, including being a vice president at Microsoft." I know two lawyers that have impressive degrees, and they disagree and argue the law, often. Which one's law degree was giving to her in error? Supreme Court Justices disagree on the law. Doctors disagree on treatments. How can that be, when they have the degrees hanging on their walls? Doesn't their degree make them right? Yet, they disagree with one-another. Assuming you can validate your assertions about Amir's education... he is not a scientist -- which is what I wrote in my opening comment. Calling his channel a science channel, inferring that he is a scientist, is deceptive. Amir is no more a scientist than Bill Nye the Science Guy. "Amir's testing methods are very valid a repeatable by anyone doing testing..." My mechanic repeatedly tested my brakes. He inspected the pads and calipers over and over. He kept getting the same conclusions. And his conclusions were correct. My other mechanic tested the car's master cylinder, and found it to be faulty. So mechanic #1's tests showed no problems. Yet, there was a problem. Mechanic #1's tests were correct, and repeatable. But it was the test that he did not do that mattered. If you do not perform the test that will reveal the problem, then you are wasting time. And when you intentionally avoid performing the test that is pertinent to the subject at hand, then you are deceptive. "Amir does, in fact, use proper testing equipment, and explains what equipment he uses, and how his test is performed, so that anyone can duplicate his testing or dispute his conclusions based on legitimate testing methods of their own." See brake test, above. "Additionally, Amir does perform "listening tests" as well." The equipment used for a listening test "is" the lab equipment. When Amir refuses to listen to Wilson Alexx V speakers, or Vandersteen Seven speakers, or PS Audio FR30 speakers, or similar quality speakers, then Amir is not using lab equipment that is capable of returning proper or accurate results. "If you actually paid attention to Amir's testing, you would see that Amir never sets out to disprove any manufactures claims and has some very positive tests and conclusions about some audio equipment." Even con men will tell the truth. Even stick-up men sometimes earn their paycheck. The issue is not with what Amir does right. The issue is with what Amir does wrong. Amir insists that cables do not affect sound quality. Amir is wrong. Amir can present dozens of tests that show that any properly functioning cable is as good as a quality, high-end cable. All that means is that Amir is not testing properly. If Amir sat down and listed to Vandersteen's System Nine set-up, and swapped between Walmart cables and Audioquest's WEL cables, Amir would know that he missed something in his testing, because the change in sound quality would be slap-in-the-face obvious. A person that is deaf in one ear would hear the difference. So Amir, for all of his shop talk, is not testing properly -- and perhaps intentionally so. He has pushed the "all cables sound the same" mantra so many times, that for him to admit he was wrong, seems to be something he does not the spine to own up to. So he always refuses to listen on the right stereos (the right lab gear). Our ears are lab equipment. Our ears can hear qualities that nothing in Amir's lab can measure.

[@JonAnderhub]

Your attacks on Amir Majidimehr of the Audio Science review are well documented. What isn't well documented is your proof that Amir's tests and conclusions are wrong. You like to selectively dismiss certain facts such as the Power Plant adding noticeable noise and try to convince people that your Power Plant is better because it lowers the impedance. Amir clearly shows with your own video that the impedance on the "low current" connections of the Power Plant was significantly higher than the specifications you claim and the impedance was actually very close to the impedance of the power strip you were testing on. Your attack on Amir over the higher impedance of the high current connection, the connection that would actually be used for amplifiers, is also well documented. What you fail to do PAul is actually prove that Amir is wrong, and by the way, Amir is really open to you proving that he is wrong. For those that want to claim "tests prove nothing it's all about the listening" then you really should pay attention to the real conclusion that Amir comes to which simply stated is that Power Plants and voltage regenerators of any type are simply a waste of money and totally unnecessary because manufactures expect their devices to see "dirty power" and build voltage regulation into the power supply of the individual devices and that the devices don't use the A.C. but convert the A.C. into D.C. to power the device.

[@TrinitronX]

As an outside observer of both ASR and PS Audio regarding the back & forth about the P12 : A lot of this confusion could have been prevented if direct communication happened with the goal of reproducing the results in a scientific manner. A second goal would be to clarify and quantify what particular aspects were being discussed, and whether these affect the intended function of the product. Analysis and drawing conclusions from this can happen only after this first step of reproducing (or failing to reproduce) those results given the same test setup. We should all try our best to arrive at the truth while putting aside our own egos and emotional attachments to ideas and stories that we might be telling ourselves. No need to add any "ad hominem" type of attacks, just talk about the data. It's OK to be wrong... we're all human, and our own senses often don't tell us the truth. Placebo effect has been established scientifically for a long time, so we must be aware that any listening tests are subjective in nature and thus subject to our own cognitive biases. It's natural and sometimes even desirable to be misled by our senses, that's how optical and auditory illusions work. However, when we're talking about these things from an engineering perspective, ideally we should attempt to do our best to remain objective and let the data do most of the "talking". Often, a very difficult part of being an engineer is to cultivate a sense of detachment to your own creations and designs. Not everything we will create in our career is going to be the best or most close to perfect design possible. Perfection is a tempting mirage, but it only truly exists in the mind. So what if the P12 has power losses due to impedance at the high current outputs, so long as this is documented and transparently disclosed to the consumer. Does 8% to 10% losses matter in the real world? Maybe, maybe not depending on the application. The 2nd law of thermodynamics says that anything we plug into a power outlet is going to have losses as a natural consequence of physics. Could it be made the most efficient possible, approaching but never achieving 100%, sure! That's often "good enough". Can we ever get 100% efficiency? No it's not possible due to the inevitable heat & energy losses. Could a newer design do better with less impedance and power losses at the "high current" output? Most likely yes. So what if it adds some of those lower frequency harmonic noise to the AC output, given that other experiments plugging other devices into those outputs results in no audible differences. Given that most audio devices will have their own power regulator circuits which do their best to throw away any of that noise anyway (AC to DC converters with full bridge rectifiers & voltage regulators, AC stepdown transformer stages, filters, etc...). As long as we are all on the same page as to the design's specs, limitations, and the physics and engineering principles involved, then all of: manufacturer, consumer, and reviewer will all be in agreement about the scientifically provable characteristics and limitations of such a product. Whether or not an AC voltage power re-generator & regulator has audible performance differences in the audio frequency range does not seem to be scientifically proven, although many of us may trick ourselves into thinking so (even if we're well-informed electrical or audio engineers). What is scientifically established about such a device is that it's very good at regulating the AC voltage level during brown-out or over-voltage scenarios (whether these are due to high current draw from other on-premises equipment, or problems from the power company's supplied amplitude levels being inconsistent or not equal to 120V AC). If that's the problem to be solved, then perhaps the P12 is the right tool for the job. If the problem to be solved is a very nebulous claim of audible performance difference, then there needs to be objectively provable evidence to support that. Many devices similar to the P12 exist on the market, with even wilder claims. Often, the problem that a consumer thinks is solved by such a power conditioner device, is actually solved by simply plugging devices into the same power strip due to the effect of "star grounding" because it often can solve ground loop voltage differences which otherwise would occur if each piece of gear was using different outlets or even different branch circuits. Given that problems with ground loops and the "Pin 1" problem have been around for a long time, and are still _very misunderstood_ , it's likely that we are only beginning to fully understand the other complexities involved with the myriad permutations of gear and interconnections, and the problems this can cause. Recent AES papers on these topics are not that old, and happened within the past 10-15 years. For comparison, how long ago was it that we were taught in school that all dinosaurs didn't have feathers? In 1996, the first fossil evidence of a dinosaur with feathers was found. Since then, others have followed. Another example: How many of us were taught in school that the tongue has either 4 or 5 different taste zones? (e.g. sweet, sour, salty, bitter, and sometimes umami) As it turns out, all areas of the tongue can sense all of these tastes. The original research behind that myth / misconception was revisited in 1974, yet still that misconception was propagated through schools up until the late 1990s! So, thus (at risk of offending the pun-haters among us) we must take all the knowledge that we think we know with a "grain of _*salt*_". 😁

And this is why people who don't pay attention to testing drive me nuts. If you actually paid attention to the testing you would understand that this PS Power regenerator or ANY other power supply or regenerator couldn't possibly make any audio device sound different or better. Any and all A.C. is isolated completely from any and all audio devices by the internal power regulator in the device. All manufacturers of audio devices (CD players, streamers, DACs, turntables, and amplifiers,) are aware of "dirty power" and build internal power regulators to compensate for such power. Additionally, audio devices don't use A.C. power but convert the power into D.C. So outside power conditioning can not possibly affect the "sound" of an audio device it's impossible.

[@JonAnderhub]

Amir doesn't have preconceived notions when performing tests on audio equipment. Many of Amir's videos show various audio equipment pieces living up to the manufacturer's specifications. However, even with no testing done, it's a scientific\engineering fact that the PS Audio Power Plant can not possibly have any effect on the quality of the sound because, even as Paul points out in this video, manufacturers of audio equipment build power regulation into their devices and audio equipment doesn't run on A.C. The A.C. is completely isolated from the audio device (all audio devices by the way, including DACs, Amplifiers, turntables, streaming devices, computers, etc.) so the condition of the A.C. can not possibly have an effect on the audio device's operation.
