The power to homes in the US is usually 240v that is split into two 120v phases at the power panel. In this scheme the neutral side of each phase is common and that ties to ground in the panel. If you have your audio equipment powered by more than one wall outlet and those all have home runs back to the panel I would think it best to have them come off the same leg (or phase) of incoming AC power to keep any disturbances on those lines the same.
@@janinapalmer8368 Edison three-wire is its origin. Edison was a nasty individual when it came to trying to further his DC system and his wealth. The migration to AC couldn't be too different to avoid the public turning against AC, plus a balancing neutral has its advantages. Imagine, a DC power plant on every block. That would have been good for global warming.
That has been debated for over 30 years. Is it better to run each mono block off the same leg or off opposing legs of the sine wave? Absolute Sound asked it's readers that question and asked for people who did try A-B comparisons to write in with their results (this was before Al Gore invented the internet). I am in the group that believe a balanced load at the panel is better, so I split my equipment to draw from opposite halves of the sine wave. I also use 2 Furman iT 15 reference power conditioners, one for each leg of power. There are known benefits to balancing the draw at the panel. Do some research on the subject.....
Technically it's not illegal to use bigger gauge conductors than necessary. As a matter of cost, it almost never happens. But in my opinion a homerun carrying as heavy a load as half the receptacles in a living room or something, should end up being tens or even bigger from the joint back to the panel (I've never done residential but am union trained in commercial, so I gasp at the thought of Romex all over the place and no conduit). But the NEC never says "shall not" when it comes to exceeding caution or, in this case, exceeding minimization of I squared R loss because transients.
I installed a dedicated 20 amp line from the fuse box to a PS Powerplant 5 and a hospital grade 20 amp outlet which has very firm connection. Very happy.
Can someone shed some light on this because I am not sure I get it. If the power regenerator spits out clean 50/60Hz sine wave with an adequate amount of VA what does my equipment care how the electricity got there in the first place?
The audio industry has learned that the physics of electrons is still very much not fully understood. They are still discovering things that defy common sense. Try researching USB cables and their effect on sound quality from a DAC. The "bits are bits" crowd says it should not matter. But A-B testing proves it does matter. The cost of a quality power cord that improves the musicality of the music can be a small percentage of the entire system cost so I have tried various power cords (all under $200) and have upgraded my entire system. For me the sound difference was immediate and clear. Interestingly, the lower priced models sounded better than some of the more expensive models.
In North America, the service voltage tolerance is +/-5%, 114-126 for 120v. In that range, nothing is done. If it goes -13/+6% they have to take prompt action to fix it. But that's just to the meter. the electrical code allows up to 5% voltage drop between the feeders and branch circuits. A dedicated home run, using 10 AWG for 20 amps removes the 5% drop risk. You should use premium outlets and if using a 20 amp breaker, 20 amp outlets as the breaker should protect the lowest rated element of the installed circuit.
Great advise from Paul, although you don't need «thick» wiring: just apply the code (REBT), usually 2,5 mm² for power -good enough for 230 V- and 1,5 mm² for lights, circuits breakers, differential protection, and a protector of transient surges if needed. On a budget, I got great improvements with better records, speaker setup (Audiophile's Guide and Reference Disc from PS Audio/Ocatve R.) and silent environments.
I am in Spain also. I went with 4mm COPPER cables - no aluminium. Use 20A 230V SLOW fuses. No need for special outlets - use sturdy, solid wall outlets of a good brand. Aka don't shop at ferreterias or chinese shops...
@@bloodcarver913 Exactly Blood Carver: good quality components in a good electrical shop. Circuits with 4 mm² are for the washing machine, 6 mm² for oven and ceramic stove. Each 2,5 mm² circuit (3 cables: phase [brown or black, neutral [blue] and earth [yellow-green]) is enough for 16 A = 3680 W. Infinity IRSV might need two 2,5 mm² or one 4 mm². No maths needed at home for our low current components, on the contrary of an industrial building, or a big network with pro gear where section is selected according to the voltage drop. These sections are for a 230 V network; 110 V need thicker cables and a 12 V battery car even bigger sections.
The advantage to increased wire size is you can maintain proper ampacity over increased distance. Plus some efficiency gains over time. Personally for my audio gear i would go with dedicated 20 amp circuits using 10 awg conductors and probably a hospital grade receptacle as a cost savings over an audio grade 100$ receptacle. Obviously some kind of overcurrent protection like a furman brand unit at the equipment. You would be surprised what gets past a standard circuit breaker.
Ideally have a dedicated line for amplifier. Then you want the AC receptacle that source(s) will be connected to be on the same leg in the panel. some say to plug amplifier straight in the wall, no power bar… and plug all your other gear (sources, preamp…) on power bar
Especially the newer pure sine wave PSU's, you can get an 800W pure sine wave PSU for like 200 bucks. It will blow away literally every piece of audiophile gear out there.
i just finished installing separate 5 x 30amp sockets back to their own dedicated fuse board with a new ground earth to ground. it cost just less than £ 1000. the difference in quality is fantastic.crisp clear with little or no noise. it is much cheaper than buying an expensive conditioner or regenerator for thousands to which it probably wont be any better to the ear. so i have to differ a little with paul here. if you can fit a dedicated fuse board and separate 2.5 cables to their own sockets ,youll hear a big difference. then if you have any cash back ,purchase and top mains cable into the pre amp or dac or amp.that again made a huge difference.
Keep in mind that power in the UK and power in the US are quite different. Our supply is extremely dirty and if you want to listen anytime before 11pm, then you are going to have a lot of noise in the system. Paul did a video "Why you system sounds better at night" which discussed this issue. When I lived in Ca 30 yrs ago, you could hear the noise levels declining after 10:30pm. By 11:30pm, the music sounded so much better than it did during "prime time" that I frequently would wait until late in the evening to turn on and warm up the amps. With my power conditioners in the system, I no longer have any dirty electric noises interfering with the music
Paul is correct about "sharing the line" with other non-audio devices. If you use dedicated (home run) lines built from (20 amp rated) generic parts you probably really don't need a "re generator".
It could be useful if your near the end of the line. In the USA it's going to range between 125v and 115v, maybe even as low as 110v. In general I'd say its probably cheaper to have a few home runs ran than to get a power conditioner/regenerator. But if the line in is at the lower side of the range, it might be the only way to get the most out of the equipment. Other issues can cause voltage drop off like bad or corroded connections, which are general electrical system issues you probably want to fix anyway.
Was just doing some reading on this. I have very easy access to my breaker and romex runs from basement to the outlets in living room stereo system. Had been thinking of having those outlets and romex changed, with a dedicated line to two outlets (maybe 15' runs x2). Like Juan in the letter mentioned though, IT'S EXPENSIVE! Living in the city, in old houses, neighbor that does a ton of shop/metal work, I really would like to have solid AC.....but maybe, I'd only gain like 5% performance/improvement for a lot of $$$$!!
and look: PS Audio uses and promotes very expensive snake oil power cables from Audioquest! Those advices are for rich people only, not for 90 % of the usual music lovers that we are. Keep our hobby REAL! Cheers!
Regarding the regenerator I'd finalize my system in terms of audio components, set them up in the room (and finalize the room as much as you can), and then make sure you really know how everything sounds before I spent money on a regenerator, and at the last step I'd make sure I could try it out at home before buying. I've heard plenty of very serious, high end audiophiles neither hear nor measure any difference. Whether it means that it doesn't do enough to change the sound in general or if they just have clean enough power to begin with doesn't really matter, the point is that it's not a guarantee that it will help your system and you won't know for sure unless you truly know how your system sounds before you try it.
I ran a dedicated duplex for my system because it's an older house and though the breakers/wiring were modernized, a couple circuits still have 2-prong outlets. The direct grounding, the more secure grip of the receptacle, and the dedicated circuit did seem to improve things. I left components with wall-wart power supplies on the older circuit, and the rest (with better than stock but not pricey power cables) are on the dedicated line. Overall any minor electronic/electric operational noise was long gone and the nuances were more audible. But if my outlets were grounded, and especially if I had a power regenerator, I wouldn't have done $hit.
just advice for everyone here, all you want to do is a direct power line only for audio equipment and a good powerstrip that doesnt cause groundloop on your components. regenerator is only necessary if you have a really old american house with terrible wiring etc
If your audio equipment is well designed it should be capable to filter noise and small voltage fluctuations As long as your supply at wall socket can provide 220/110Vac @15A depending on where you located even gold plated cicuit breaker and cables wont improve the sound.
@@Viagra_risk_PERMANENT_insomnia guessing you never used a oscilloscope or network analyzer lab equipment to test audio equipment. You do know what the function of the big electrolytic capacitors are in the power supply block chain of all well designed equipment?
@@Viagra_risk_PERMANENT_insomnia that is why I said from start. Your wall outlet socket must be able to supply the AC voltage at the rated current. You can add extra filters if you want but your equipment already does the filtering except for brown outs or big surges on your supply that is caused by supplier or shorts on the grid ect. But good designed equipment will have taken these in account. It is like buying a diesel vehicle that already comes fitted with fuel filter and water trap for contaminated fuel so if you buy a vehicle without these precautions already build in you wont go far.
@@pietpompiepompiepiet940 no I don't use measurement devices with my stereo system. I listen closely and it sounds great plugged into a dedicated line.
Hey Paul, mind giving us an overview on how the power of a generator works? Has anybody ever thought of the idea of shielding the AC means power line? Or ferrite beans?
Regenerator transforms AC to DC and then back to AC. However, your equipment will also convert AC to DC and make sure its clean and ready to use, so in my opinion the extra step of DC/AC conversion is not needed.
The biggest difference in a direct power supply design is that you align your line, then you don't need a power regenerator in the first place. The alignment must be done right through to your individual Audio components, to make the magic difference and it must be aligned right from the DB Board. The expensive stranded high end power chords and mains conditioner/ power generator are a total waste of money and can not outperform power supply alignment design. Tried and tested the design many times and it will always beat any conditioner/ regenerator design and is a extremely cost effective solution.
Isn't the one of the roles of the power supply in audio devices to "tooling" the electricity from the mains? Audio producers often boast about their SUPER POWER SUPPLIES installed in their super amplifiers - "virtual batteries" for example... So, do not you thing that what goes to the transistor must be good, not AC coming to the power supply - because decent supply ccan handle it perfectly ?
For switch mode power supplies, does this really matter? I can see for a conventional transformer power supply, noise might make it through the filter caps. However, in a switch mode, the original AC is rectified, chopped up to a high frequency, transformed, and then re-rectified.
@Douglas Blake They also avoid a huge iron core transformer. My old Peavey CS-800 weighs in at 45 pounds! If it ever dies, I can still use it in my workouts.
Most audiophiles prefer a linear supply because of the musical advantages. There are several brands of equipment that the SMPS is known to be the weak link and there are off the shelf conversion kits to switch them to linear supplies.
@Douglas Blake So sad that you resort to such characterizations. Since you have no experience in testing and comparing power cords, your opinion is worthless. If you had tested brand A and brand X, then you would have something worth reading, but since you have not, then your opinion is just wasted bandwidth.
@Douglas Blake I don't think audiophiles are any more gullible then any other group. Car enthusiasts, TV enthusiasts, runners, audiophiles, every group is full of people who "believe the hype".
@Douglas Blake Have you been in the car tuner scene? People spending hundreds of dollars replacing car parts because they believe a $45,000 sports car can get 10% more power with a $300 part that the OEM somehow couldn't figure out. How about people bragging about phone resolution that no human eye could resolve, or refresh rates beyond human capability. What about wine drinkers? Plenty of studies have shown expensive wine is no better than cheap wine, yet people still buy it. That's like people who mix top shelf vodka with imitation cranberry juice from a juice gun. Then there are gamers claiming to need 240hz refresh rates on their monitors. That's 4 milliseconds. Human reaction time is around 250 milliseconds. Audiophiles are people, and most people are gullible about technical subjects.
I’m confused, does the AC really matter if it’s all converted to DC. This what I was told another forum where measurements are everything. I won’t mention names 😉
Yes, it's easy to get confused and there's loads of conflicting information around. To say it doesn't matter is simply an easy way to skirt the facts that are in themselves complex. Everything we hear (or see in a video system) starts out as AC, gets converted to DC, and then remodulated back into AC (only this time the AC is the music). The quality of that DC is directly related to how it is converted and what shape it was in to start with. A simple example would be a power amplifier. Its power supply is typically quite simple: a transformer, bridge and capacitors. If the incoming AC wavers in level, so too does the output DC of this supply. And then there's noise, both on the line and radiated. It's just not that simple.
I have to wonder, that although there would be obvious benefit to not sharing the AC line to your audio hardware with power users like refrigerators, AC, .... of having a good stand alone line from the breaker/ outside mains. Do the noise makers, LED lights, motors, .... feed that noise back in at the breaker? Does it matter than they are on a different "star" of that AC network? It would seem thaty without filtering of each line at the panel the noise would just ride on all lines.

The power transformers, rectifiers, and filters in each piece of equipment should be adequate to deal with defects in the electricity that comes though the AC wiring, outlets, and cords. I say SHOULD because some lower-priced equipment IS deficient. Worthwhile equipment, however, will Always do the job well enough that power conditioning or regeneration will be only a protective measure against damage from non-average occurrences such as spikes and surges.
Power from the public grid is dirty. The power supplies in stereo equipment are not designed to clean up that dirt. They cannot make bad voltage into good voltage. A power re-generator ensures that your connected equipment will receive 100% clean, steady, voltage regulated power, and that helps.
@@NoEgg4u Sorry, I find it difficult to argue with someone about bad voltage and good voltage. And what exactly are power supplies designed for in your opinion? For clean AC input? Sure not!
@@edgar9651 "Sorry, I find it difficult to argue with someone" 1) Why are you looking for an argument? 2) You are not sorry. "And what exactly are power supplies designed for in your opinion? For clean AC input? Sure not!" You agree with me that power supplies are not designed to correct dirty power. If you believe that power supplies are the holy grail of ensuring clean power delivery to the boxes on which they are installed, then please contact Amazon, eBay, Thomson Reuters, Facebook, Bloomberg, Twitter, etc, and tell them that they are wasting money on feeding their data centers with clean power. Those companies, and countless others, have data centers that cost hundreds of millions of $$. Those companies, and countless others, have isles and isles of servers that each cost $50,000 or more. So let those companies know that those $50,000 servers have power supplies which will feed their servers clean power. Nothing dirty from the public grid can touch their servers. All they need is good surge suppression and battery backup in case of a blackout. But as long as the power company stays active, none of those companies need to regenerate the power that feeds their data centers, because all of their servers have power supplies. All of those companies have "on-line" uninterruptible power supplies (UPS), that cost on par with homes in the finest neighborhoods. One of the reasons for their high cost is that they take multi-megawatts of electricity from the public power grid, and they convert it to DC, and then convert it back to AC, and it is that newly generated AC that they use to feed their $50,000 servers. Doing the double conversion is not free. It takes power to change the power. It costs approximately 5% to 10%, depending on the efficiency of the equipment. So let those companies know that since those servers have power supplies, there is not need for them to have those wildly expensive UPS systems, especially the ones that waste electricity on unnecessarily converting the power twice. After you contact those companies, the next agenda item if for you to contact hospitals, because they do the same thing. Let the hospitals know that when they are performing open-heart surgery, that their equipment includes power supplies, so there is no need for them to generate their own clean power. Also, re-negotiate their insurance policies to exclude coverage for losses when they stop generating their own clean power, in favor of power directly from the public power grid. Their policies require them to have clean power, to ensure no power related computer down time, and to ensure no loss of life due to power issues. But according to you, their equipment's power supplies is all that they need, and no need for them to generate their own clean power. So that should be stricken from their insurance policies. Perhaps you should contact NASA, too. When they are monitoring a space launch, they, too, are wasting money by feeding their control center cleanly generated power. All of their equipment contains power supplies. You will save the tax payers money, by ending the wasteful double conversion of their electricity and expensive on-line generators. If you need assistance in reaching all of these companies, then check the other comments. There are other ignoramuses posting comments similar to yours.
Its quackery, of course. The amplifier runs on DC, not AC, and the first thing it does with that pretty regenerated AC power is chop it to bits to turn it into nasty rectified 120Hz pulsing DC rich with harmonics. The internal filtering and decoupling are what makes the power nice, not what's coming out of the wall. This is even more ludicrous if you buy one of PS Audio's amplifiers with integrated class-D amplifier modules. Those use HF resonant mode switching techniques to efficiently generate the DC, which make the amplifier a potential source of RF interference to other equipment.
And the reason he gives this advice is his getting along in terms of years, so he just wants to ride PS Audio into the sunset. This is unfortunate for those taking this advice as they are being fleeced for large sums of money.
@@kytddjj Of course Paul deleted my comment to you (Edit: or probably nannyTube, more likely because it was naughty) that was much deserved. But what I typed there are simple facts. Go read any book on audio amplifier design and stop listening to this nonsense.
@@mysock351C In order for the amplifier to run on DC, it is 100% dependent on using the dirty power being delivered to it, via AC. When amplifiers are powered by dirty power, then they run dirty. HF resonant mode switching will be done based on its power delivery, which is dirty. It cannot perform ideally, with less than ideal power delivery. According to your assertions, the amps would not care if the AC was delivered at different frequencies, different voltages, etc. The internal filtering and decoupling makes it all clean? That is nonsense. It is not quackery, of course. I realize that you wrote it on the internet, and that makes it true. I am relieved that you did not write that the Earth is flat, because I would be surprised to learn that that is true.

As long as you're going through a power regenerator it shouldn't matter what romex or outlet you use. But Paul admits (in a previous video) that the audioquest power cable makes a difference on the regenerator. Go figure.
You can get similar results with power cords that cost under $100. I tried a few and found they work quite well. As Paul found, I also found that placing them before the power conditioners/ generators does make a difference as well as using them on each and every source as well as pre amp and mono block amps
@@briangc1972 that's exciting for you that sub $100 get you similar results. I have not had that experience. So, if a power regeneration unit (not power conditioner) is improved by power cords the theory of regeneration is out the window. It shouldn't matter what you feed it. The unit makes new "perfect" power.
@@mjot2360 I think it is the fact that the OEM power cords are so poorly constructed that I have had noticeable improvements by changing the power cords. All power cords have the potential to cause interference in the signal path. The OEM cords are just very good at doing so. The aftermarket power cords correct or minimize the degradation.
Ah! I see why this has come up, "PS Audio invented the category of Power Regenerators." So naturally one will be recommended. From what I have read most instances of reasonable stable electrical supply will NOT improve with one, but it will make your bank account balance a lot lower! 😆
Paul, regarding your opening comments on the import of electrical current, you have never been so right. Even though your proposed solutions and even viewing your room lead me to think there's much more one can do to achieve still far greater superior AC than you indicate here.
The next logical step is to upgrade all the wire from the house to the generator in the power station. And make it a dedicated line just for you with no other houses sharing it. What's the point in replacing only the last hundred feet? I think that in japan, some people are doing this.

Allegedly some extreme (as we saw that) audiophiles (that word did not exist back then, we would just refer to them as weirdo's) in Japan would run their gear of batteries. The story there made much more sense. Batteries are already perfect DC with low Ri and you would not have to worry about the AC ripple that under load would get trough anyway. Dirty power was not an issue back then. But you have a good point. Buy a Tesla power bank if you believe in it.

I installed a dedicated 20 amp line from the fuse box to a PS Powerplant 5 and a hospital grade 20 amp outlet which has very firm connection. Very happy.
Can someone shed some light on this because I am not sure I get it. If the power regenerator spits out clean 50/60Hz sine wave with an adequate amount of VA what does my equipment care how the electricity got there in the first place?

In North America, the service voltage tolerance is +/-5%, 114-126 for 120v. In that range, nothing is done. If it goes -13/+6% they have to take prompt action to fix it. But that's just to the meter. the electrical code allows up to 5% voltage drop between the feeders and branch circuits. A dedicated home run, using 10 AWG for 20 amps removes the 5% drop risk. You should use premium outlets and if using a 20 amp breaker, 20 amp outlets as the breaker should protect the lowest rated element of the installed circuit.
Great Words, Paul! Thank you for letting us know. The Power ist the Blood of the System. :)
Great advise from Paul, although you don't need «thick» wiring: just apply the code (REBT), usually 2,5 mm² for power -good enough for 230 V- and 1,5 mm² for lights, circuits breakers, differential protection, and a protector of transient surges if needed. On a budget, I got great improvements with better records, speaker setup (Audiophile's Guide and Reference Disc from PS Audio/Ocatve R.) and silent environments.
I am in Spain also. I went with 4mm COPPER cables - no aluminium. Use 20A 230V SLOW fuses. No need for special outlets - use sturdy, solid wall outlets of a good brand. Aka don't shop at ferreterias or chinese shops...
@@bloodcarver913 Exactly Blood Carver: good quality components in a good electrical shop. Circuits with 4 mm² are for the washing machine, 6 mm² for oven and ceramic stove. Each 2,5 mm² circuit (3 cables: phase [brown or black, neutral [blue] and earth [yellow-green]) is enough for 16 A = 3680 W. Infinity IRSV might need two 2,5 mm² or one 4 mm². No maths needed at home for our low current components, on the contrary of an industrial building, or a big network with pro gear where section is selected according to the voltage drop. These sections are for a 230 V network; 110 V need thicker cables and a 12 V battery car even bigger sections.
The advantage to increased wire size is you can maintain proper ampacity over increased distance. Plus some efficiency gains over time. Personally for my audio gear i would go with dedicated 20 amp circuits using 10 awg conductors and probably a hospital grade receptacle as a cost savings over an audio grade 100$ receptacle. Obviously some kind of overcurrent protection like a furman brand unit at the equipment. You would be surprised what gets past a standard circuit breaker.
Ideally have a dedicated line for amplifier. Then you want the AC receptacle that source(s) will be connected to be on the same leg in the panel.
some say to plug amplifier straight in the wall, no power bar… and plug all your other gear (sources, preamp…) on power bar
On the practical side, I use a good UPS and call done.
Especially the newer pure sine wave PSU's, you can get an 800W pure sine wave PSU for like 200 bucks. It will blow away literally every piece of audiophile gear out there.
i just finished installing separate 5 x 30amp sockets back to their own dedicated fuse board with a new ground earth to ground. it cost just less than £ 1000. the difference in quality is fantastic.crisp clear with little or no noise. it is much cheaper than buying an expensive conditioner or regenerator for thousands to which it probably wont be any better to the ear. so i have to differ a little with paul here. if you can fit a dedicated fuse board and separate 2.5 cables to their own sockets ,youll hear a big difference. then if you have any cash back ,purchase and top mains cable into the pre amp or dac or amp.that again made a huge difference.
Keep in mind that power in the UK and power in the US are quite different. Our supply is extremely dirty and if you want to listen anytime before 11pm, then you are going to have a lot of noise in the system. Paul did a video "Why you system sounds better at night" which discussed this issue. When I lived in Ca 30 yrs ago, you could hear the noise levels declining after 10:30pm. By 11:30pm, the music sounded so much better than it did during "prime time" that I frequently would wait until late in the evening to turn on and warm up the amps. With my power conditioners in the system, I no longer have any dirty electric noises interfering with the music
Paul is correct about "sharing the line" with other non-audio devices. If you use dedicated (home run) lines built from (20 amp rated) generic parts you probably really don't need a "re generator".
It could be useful if your near the end of the line. In the USA it's going to range between 125v and 115v, maybe even as low as 110v. In general I'd say its probably cheaper to have a few home runs ran than to get a power conditioner/regenerator. But if the line in is at the lower side of the range, it might be the only way to get the most out of the equipment. Other issues can cause voltage drop off like bad or corroded connections, which are general electrical system issues you probably want to fix anyway.
I also did what Paul suggested a month ago, gave different line for my audio equipment from main source.
Was just doing some reading on this. I have very easy access to my breaker and romex runs from basement to the outlets in living room stereo system. Had been thinking of having those outlets and romex changed, with a dedicated line to two outlets (maybe 15' runs x2). Like Juan in the letter mentioned though, IT'S EXPENSIVE! Living in the city, in old houses, neighbor that does a ton of shop/metal work, I really would like to have solid AC.....but maybe, I'd only gain like 5% performance/improvement for a lot of $$$$!!
and look: PS Audio uses and promotes very expensive snake oil power cables from Audioquest! Those advices are for rich people only, not for 90 % of the usual music lovers that we are. Keep our hobby REAL! Cheers!
Regarding the regenerator I'd finalize my system in terms of audio components, set them up in the room (and finalize the room as much as you can), and then make sure you really know how everything sounds before I spent money on a regenerator, and at the last step I'd make sure I could try it out at home before buying. I've heard plenty of very serious, high end audiophiles neither hear nor measure any difference. Whether it means that it doesn't do enough to change the sound in general or if they just have clean enough power to begin with doesn't really matter, the point is that it's not a guarantee that it will help your system and you won't know for sure unless you truly know how your system sounds before you try it.
I ran a dedicated duplex for my system because it's an older house and though the breakers/wiring were modernized, a couple circuits still have 2-prong outlets. The direct grounding, the more secure grip of the receptacle, and the dedicated circuit did seem to improve things.
I left components with wall-wart power supplies on the older circuit, and the rest (with better than stock but not pricey power cables) are on the dedicated line. Overall any minor electronic/electric operational noise was long gone and the nuances were more audible.
But if my outlets were grounded, and especially if I had a power regenerator, I wouldn't have done $hit.
just advice for everyone here, all you want to do is a direct power line only for audio equipment and a good powerstrip that doesnt cause groundloop on your components. regenerator is only necessary if you have a really old american house with terrible wiring etc
PS Audio power supplies must be really poor if they cannot deliver pure and stable DC from a standard AC wall outlet without a Regenerator in-line.
If your audio equipment is well designed it should be capable to filter noise and small voltage fluctuations
As long as your supply at wall socket can provide 220/110Vac @15A depending on where you located even gold plated cicuit breaker and cables wont improve the sound.
@@Viagra_risk_PERMANENT_insomnia guessing you never used a oscilloscope or network analyzer lab equipment to test audio equipment.
You do know what the function of the big electrolytic capacitors are in the power supply block chain of all well designed equipment?
@@Viagra_risk_PERMANENT_insomnia that is why I said from start. Your wall outlet socket must be able to supply the AC voltage at the rated current. You can add extra filters if you want but your equipment already does the filtering except for brown outs or big surges on your supply that is caused by supplier or shorts on the grid ect. But good designed equipment will have taken these in account.
It is like buying a diesel vehicle that already comes fitted with fuel filter and water trap for contaminated fuel so if you buy a vehicle without these precautions already build in you wont go far.
@@Viagra_risk_PERMANENT_insomnia follow the science when it comes to electrical issues.
@@pietpompiepompiepiet940 no I don't use measurement devices with my stereo system. I listen closely and it sounds great plugged into a dedicated line.
Hey Paul, mind giving us an overview on how the power of a generator works? Has anybody ever thought of the idea of shielding the AC means power line? Or ferrite beans?
Regenerator transforms AC to DC and then back to AC. However, your equipment will also convert AC to DC and make sure its clean and ready to use, so in my opinion the extra step of DC/AC conversion is not needed.
The biggest difference in a direct power supply design is that you align your line, then you don't need a power regenerator in the first place.
The alignment must be done right through to your individual Audio components, to make the magic difference and it must be aligned right from the DB Board.
The expensive stranded high end power
chords and mains conditioner/ power generator are a total waste of money and can not outperform power supply alignment design.
Tried and tested the design many times and it will always beat any conditioner/ regenerator design and is a extremely cost effective solution.
Those power chords hurt my ears unless in the key of C.
14awg is for 15amp circuits. 10 or 12awg is just insurance. No worries there. Master Electrician.
Isn't the one of the roles of the power supply in audio devices to "tooling" the electricity from the mains?
Audio producers often boast about their SUPER POWER SUPPLIES installed in their super amplifiers - "virtual batteries" for example...
So, do not you thing that what goes to the transistor must be good, not AC coming to the power supply - because decent supply ccan handle it perfectly ?
For switch mode power supplies, does this really matter? I can see for a conventional transformer power supply, noise might make it through the filter caps. However, in a switch mode, the original AC is rectified, chopped up to a high frequency, transformed, and then re-rectified.
@Douglas Blake They also avoid a huge iron core transformer. My old Peavey CS-800 weighs in at 45 pounds! If it ever dies, I can still use it in my workouts.
Most audiophiles prefer a linear supply because of the musical advantages.
There are several brands of equipment that the SMPS is known to be the weak link and there are off the shelf conversion kits to switch them to linear supplies.
@Douglas Blake So sad that you resort to such characterizations. Since you have no experience in testing and comparing power cords, your opinion is worthless. If you had tested brand A and brand X, then you would have something worth reading, but since you have not, then your opinion is just wasted bandwidth.
@Douglas Blake I don't think audiophiles are any more gullible then any other group. Car enthusiasts, TV enthusiasts, runners, audiophiles, every group is full of people who "believe the hype".
@Douglas Blake Have you been in the car tuner scene? People spending hundreds of dollars replacing car parts because they believe a $45,000 sports car can get 10% more power with a $300 part that the OEM somehow couldn't figure out.
How about people bragging about phone resolution that no human eye could resolve, or refresh rates beyond human capability.
What about wine drinkers? Plenty of studies have shown expensive wine is no better than cheap wine, yet people still buy it. That's like people who mix top shelf vodka with imitation cranberry juice from a juice gun.
Then there are gamers claiming to need 240hz refresh rates on their monitors. That's 4 milliseconds. Human reaction time is around 250 milliseconds.
Audiophiles are people, and most people are gullible about technical subjects.
I’m confused, does the AC really matter if it’s all converted to DC. This what I was told another forum where measurements are everything. I won’t mention names 😉
Yes, it's easy to get confused and there's loads of conflicting information around. To say it doesn't matter is simply an easy way to skirt the facts that are in themselves complex. Everything we hear (or see in a video system) starts out as AC, gets converted to DC, and then remodulated back into AC (only this time the AC is the music). The quality of that DC is directly related to how it is converted and what shape it was in to start with. A simple example would be a power amplifier. Its power supply is typically quite simple: a transformer, bridge and capacitors. If the incoming AC wavers in level, so too does the output DC of this supply. And then there's noise, both on the line and radiated. It's just not that simple.
I have to wonder, that although there would be obvious benefit to not sharing the AC line to your audio hardware with power users like refrigerators, AC, .... of having a good stand alone line from the breaker/ outside mains. Do the noise makers, LED lights, motors, .... feed that noise back in at the breaker? Does it matter than they are on a different "star" of that AC network? It would seem thaty without filtering of each line at the panel the noise would just ride on all lines.
@Douglas Blake Yes my thoughts exactly. Seems like filtering at the breaker would be good.

The power transformers, rectifiers, and filters in each piece of equipment should be adequate
to deal with defects in the electricity that comes though the AC wiring, outlets, and cords.
I say SHOULD because some lower-priced equipment IS deficient.
Worthwhile equipment, however, will Always do the job well enough that power conditioning or regeneration
will be only a protective measure against damage from non-average occurrences such as spikes and surges.
It seems Paul recommends PS Audio power generators before all the other PS Audio equipment. What does that tell us about PS Audio equipment...
Power from the public grid is dirty. The power supplies in stereo equipment are not designed to clean up that dirt. They cannot make bad voltage into good voltage.
A power re-generator ensures that your connected equipment will receive 100% clean, steady, voltage regulated power, and that helps.
@@NoEgg4u Sorry, I find it difficult to argue with someone about bad voltage and good voltage. And what exactly are power supplies designed for in your opinion? For clean AC input? Sure not!
@@NoEgg4u bullshit
@@edgar9651 "Sorry, I find it difficult to argue with someone"
1) Why are you looking for an argument?
2) You are not sorry.
"And what exactly are power supplies designed for in your opinion? For clean AC input? Sure not!"
You agree with me that power supplies are not designed to correct dirty power.
If you believe that power supplies are the holy grail of ensuring clean power delivery to the boxes on which they are installed, then please contact Amazon, eBay, Thomson Reuters, Facebook, Bloomberg, Twitter, etc, and tell them that they are wasting money on feeding their data centers with clean power.
Those companies, and countless others, have data centers that cost hundreds of millions of $$.
Those companies, and countless others, have isles and isles of servers that each cost $50,000 or more.
So let those companies know that those $50,000 servers have power supplies which will feed their servers clean power. Nothing dirty from the public grid can touch their servers. All they need is good surge suppression and battery backup in case of a blackout. But as long as the power company stays active, none of those companies need to regenerate the power that feeds their data centers, because all of their servers have power supplies.
All of those companies have "on-line" uninterruptible power supplies (UPS), that cost on par with homes in the finest neighborhoods. One of the reasons for their high cost is that they take multi-megawatts of electricity from the public power grid, and they convert it to DC, and then convert it back to AC, and it is that newly generated AC that they use to feed their $50,000 servers.
Doing the double conversion is not free. It takes power to change the power. It costs approximately 5% to 10%, depending on the efficiency of the equipment.
So let those companies know that since those servers have power supplies, there is not need for them to have those wildly expensive UPS systems, especially the ones that waste electricity on unnecessarily converting the power twice.
After you contact those companies, the next agenda item if for you to contact hospitals, because they do the same thing.
Let the hospitals know that when they are performing open-heart surgery, that their equipment includes power supplies, so there is no need for them to generate their own clean power.
Also, re-negotiate their insurance policies to exclude coverage for losses when they stop generating their own clean power, in favor of power directly from the public power grid. Their policies require them to have clean power, to ensure no power related computer down time, and to ensure no loss of life due to power issues. But according to you, their equipment's power supplies is all that they need, and no need for them to generate their own clean power. So that should be stricken from their insurance policies.
Perhaps you should contact NASA, too. When they are monitoring a space launch, they, too, are wasting money by feeding their control center cleanly generated power. All of their equipment contains power supplies. You will save the tax payers money, by ending the wasteful double conversion of their electricity and expensive on-line generators.
If you need assistance in reaching all of these companies, then check the other comments. There are other ignoramuses posting comments similar to yours.
No Paul, it is not illegal to use a larger gauge wire with a smaller circuit breaker.
This is like I’m gonna be home everyday 24 hours a day like retired human being just stay home and watch those stereos all day long 😭
AC Power is the new interlink.
Great to receive an honest advice !
Its quackery, of course. The amplifier runs on DC, not AC, and the first thing it does with that pretty regenerated AC power is chop it to bits to turn it into nasty rectified 120Hz pulsing DC rich with harmonics. The internal filtering and decoupling are what makes the power nice, not what's coming out of the wall. This is even more ludicrous if you buy one of PS Audio's amplifiers with integrated class-D amplifier modules. Those use HF resonant mode switching techniques to efficiently generate the DC, which make the amplifier a potential source of RF interference to other equipment.
And the reason he gives this advice is his getting along in terms of years, so he just wants to ride PS Audio into the sunset. This is unfortunate for those taking this advice as they are being fleeced for large sums of money.
@@kytddjj Of course Paul deleted my comment to you (Edit: or probably nannyTube, more likely because it was naughty) that was much deserved. But what I typed there are simple facts. Go read any book on audio amplifier design and stop listening to this nonsense.
@@mysock351C In order for the amplifier to run on DC, it is 100% dependent on using the dirty power being delivered to it, via AC.
When amplifiers are powered by dirty power, then they run dirty.
HF resonant mode switching will be done based on its power delivery, which is dirty. It cannot perform ideally, with less than ideal power delivery.
According to your assertions, the amps would not care if the AC was delivered at different frequencies, different voltages, etc. The internal filtering and decoupling makes it all clean? That is nonsense.
It is not quackery, of course. I realize that you wrote it on the internet, and that makes it true.
I am relieved that you did not write that the Earth is flat, because I would be surprised to learn that that is true.

As long as you're going through a power regenerator it shouldn't matter what romex or outlet you use. But Paul admits (in a previous video) that the audioquest power cable makes a difference on the regenerator. Go figure.
You can get similar results with power cords that cost under $100. I tried a few and found they work quite well. As Paul found, I also found that placing them before the power conditioners/ generators does make a difference as well as using them on each and every source as well as pre amp and mono block amps
@@briangc1972 that's exciting for you that sub $100 get you similar results. I have not had that experience. So, if a power regeneration unit (not power conditioner) is improved by power cords the theory of regeneration is out the window. It shouldn't matter what you feed it. The unit makes new "perfect" power.
@@mjot2360 I think it is the fact that the OEM power cords are so poorly constructed that I have had noticeable improvements by changing the power cords. All power cords have the potential to cause interference in the signal path. The OEM cords are just very good at doing so. The aftermarket power cords correct or minimize the degradation.
I like small speakers, I like tall speakers😊
Battery power should be the true way to go. Have each piece of equipment run off its own isolated power bank. Completely off the grid.
Ah! I see why this has come up, "PS Audio invented the category of Power Regenerators." So naturally one will be recommended. From what I have read most instances of reasonable stable electrical supply will NOT improve with one, but it will make your bank account balance a lot lower! 😆
Paul, regarding your opening comments on the import of electrical current, you have never been so right. Even though your proposed solutions and even viewing your room lead me to think there's much more one can do to achieve still far greater superior AC than you indicate here.
I run the power from the outlet into a Snekoyll power cleaner all the time.
It would most likely work much better for you if the used a real one. Seems pointless to knowingly waste money on Snekoyll all the time.
The next logical step is to upgrade all the wire from the house to the generator in the power station. And make it a dedicated line just for you with no other houses sharing it. What's the point in replacing only the last hundred feet? I think that in japan, some people are doing this.

@@NoEgg4u The last quality piece of cord " takes the sloshing power and aligns it".. really? The cord aligns the power? It's just a piece of cord..

So basicly what Paul has said with this and his last video is If you've got lots of money then you've got to buy braided power cables and high end connecting cables with your stereo.....but if you have a "budget" then never mind....just spend your money on your basic equipment as the snake oil stuff is only noticeable by the high end audiofools

The story there made much more sense. Batteries are already perfect DC with low Ri and you would not have to worry about the AC ripple that under load would get trough anyway. Dirty power was not an issue back then. But you have a good point. Buy a Tesla power bank if you believe in it.
