Easy DIY Shielded Audiophile Grade AC Power Cords, Twisted Too! 

Yes same for me, but I found it to be too detailed/cold/analytical with the rhodium plated connectors. Its like changing a whole amp lol

No one should trust their “ears” as they are one of the most inaccurate senses and highly susceptible to psychological influences. In other words, they’re easy to trick. But if the end result is you enjoying it, then that’s a win of course.

@@TheEchelon lol you should trust only your ears and not others

@@TheEchelon What should one trust then?Specs and data on a paper??? We all listen through our ears, man, and it's them who tell us if what we listen to is of our liking or not. No BS!

@@MasterofPlay7Hi… did you buy or make your own power cord?

Thanks a million, Mark! Just taking advantage of this to ask a basic (for me, a lerner) question: why do I see folks twisting all the internal cables and audio path wires (input wires) inside the amplifier? I see twisted cables from vintage power boards to the output transistors bolt to the heatsinks. Same thing with the "minus" and "plus" cables from the PSU to the smoothing big capacitors... In essence, what the big "benefit" of twisting wires and cables? Aren't these creating a bit of resistance end to end?? Thanks again!

@@montech5647 Hi Montech, so twisting wires is all about attempting to eliminate RF interference. If you imagine those wires all loose with different spaces all along the length any induced EMR would be different strength's depending on how close or not each wire is which in turn would pose a problem for removing it. Now imagine the wires twisted...they are all equal to the noise because of the twist & as such an equal induced noise presents a "common" noise which common mode rejection circuits can remove a lot easier than random wires. Mostly this is a problem where the wires are a feed into any amplification stage (you don't want to amplify noise) The power cables that Tharbamar made don't have to be twisted for any other reason than making it neat & easier to slide sleeves over, the same goes for speaker wires. Wire resistance doesn't have anything to do with twisting, if all wires have the same material/gauge/length they will be extremely close in resistance...loose or twisted.

Hello Mark, how critical or important is “ torquing down” the screws in this application. I just viewed a video from Furutech where they recommended a torque of 80 c (not sure of the rest). Thx, Mike.

@@markwhitfield2629 thanks for the response. I'm trying to eliminate crosstalk between input channels' cables and was advised to keep the wires and cables a bit far from each other, but this seems pretty difficult to achieve...

@@mikeeygauthier2959 That's essentially a mechanical lug, I've tightened/torqued thousands... just make sure it's really tight.

You’re welcome, enjoy!

No, sorry it is not like that. Hans Beekhuyzen explains in audio hygiene why. The power cables delivered with the component are normally not shielded. It is the shielding which is preventing the power cable to radiate disturbance to for example an RCA cable carrying the audio signal, which are mostly nearby on the backside of the component. So it is not the disturbance from outside going into the power cable.

I would twist them together first and cut the length you need after that, it would be much easier to get same lengths on all cables, thanks

yup

Hi, so you mean that shielded weaved sleeve only on the orange and yellow but not on the black ground? Even less noise floor? And ferrites?

Hi, it’s 1/2” copper shield. Exact link in video description, thanks

@@Tharbamar thank you for the swift reply. actually the link in the description takes you to multiple products... hence the question :) thanks again

I’m using them in another power cable, thanks

it’s just for demonstration purposes, I didn’t forget anything.

​@@Tharbamarok thanks. Sorry about that. But how about I use the extra strong shrink tubing on top of the shielding and then I can put the final nylon braided sleeve on top? Is that a good idea?

This video is for that purpose, thanks

Sound is richer, PS Audio AC5 with my Aquarius R2R DAC sound brighter than with my DIY cords, AC12 and my DIY cables are about the the same but AC12 is slightly quieter, Now I’m using AC12 with amplifier and rest of the components with DIY shielded power cables, thanks

Yes definitely.

Yes, here in the US, Black = HOT, White = NEUTRAL, Green = GROUND but since I’m not selling it can be anything for personal uses. I’ve tried many different shielding up to 4 layers using aluminum foil, copper tape as well as each individual conductor shielding there is no difference in audible noise improvement, my power cord is absolutely quiet even when I raise volume knob to max level on class D amplifier, there will no hiss or white noise. Thanks

Acctually as long as you use approved fittings an electrician is not required 'this does not apply to behind wall cables'

Only the right colors give the right sound...

No it can't, it still has to be certified to a UL standard in order to be legal to use in USA, whether it's for personal use or not.

This particular cable is designed to use with digital components by lifting shield ground on component side and drained on wall side but still it can be use with other type of components.

I’ve been using them so long in pro and home audio with not a single issue. Ul13 CL2 Rating and withstand to 500v. Also note most ultra high current amps are wired with very same cable inside.

Yes, most of small digital components I like them with shielded power cords, thanks

@@Tharbamar how about your USB cable running from dac to source? Shielded too?

@@leekenyon4099 I'm using Oyaide Neo+ Class A USB cable.

@@Tharbamar Ah, I have the Oyaide Class B interconnects ($40 / M) on my secondary system, and the Audioquest 'Pearl' 5M USB running all the way to my new SMSL DO200 DAC! 😁

Grounding at one end allows the shield conductor to act as an antenna and shunt any noise to a dingle ground reference. Too many paths to ground can cause ground loop hum.

Quieter overall noise floor. Thanks

Yes, absolutely, I've been using same design on SUB as well, thanks

A good power cable increases tv resolution,colors,brightness,etc basically improves everything 2nd best upgrade to any tv.

Yes you can.

It's Mogami Neglex copper not OCC, thanks

Basically when current/signal passes through the cable also carries noise as well and magnetic field generates throughout the cable. The magnetic field is absorbed by the ferrite core and the noise current is reduced with the help of ferrite core.

@@Tharbamar thanks for your answer j was experimenting with ferite beads on power cables and speaker cables and the result is that improvements are on power cables but on speaker cables are not good

Many audiophiles don't like the change it does to sound I would use it for tv only.

Yes definitely.

Thanks good cables never hurt, I also have dedicated power transformer for whole house.

Yes I’ve been using some Viborg plugs, they are very good quality. I might be using binding posts in next project, thanks

@@Tharbamar They are currently sold out of these right now but I recently got these rhodium plated copper binding posts and upgraded my Elac Unifi UB52’s with these and it made a HUGE improvement! www.amazon.com/dp/B017GRI4UM/ref=cm_sw_r_sms_api_glt_fabc_N009Y69DFQQ162KCEND7?_encoding=UTF8&psc=1

Yes, I will be trying them on my CSS 1TDX in the future, thanks

Go straight to aliexpress monosaudio iec pure copper gold plated decent good as viborg.Xangsane 6 core 1.5 silver plate occ copper probably best cable you can get double shielded round a solid core inner.sound amazing with a silver fuse wire fuse.made more difference to my system then any other cable that and better op amp best upgrade ive done.

Hi thanks for heads up, I just updated with this link amzn.to/3JGN8sA

I use Canare 4S11 in my main system.

Hi there is no drain wire, only the shield is drain on wall side by connecting to ground pin and lifted on component side better shielding, there is no ground loop when ground wire is connected to the both ends. Thanks

@@Tharbamar ok thanks but why not shield the hot and neutral together away from the ground and twise the ground around that? Wouldn't that be better shielding for that ground?

@@visiontranscend60 Probably but my main purpose of shielding is not to introduce any interference from the AC cables to surrounding cables and components, not other way around.

Hi I just updated the link, thanks

@@Tharbamar thanks!

For your information, filter circuits, active or passive, are the most common most cheap and most simple elemenst of electronic devices. The cost is few $. Do you really believe, when you buy an amplifier for $2000, those hifi and electric engineers who made that, they can't put $2 value filters in your device as many as they want and anywhere as the want if necessary ? They give you a sh...t product for $2000 because they are not professional, they don't understand how the mains work ? You think your merchans will solve that engineering problem with their "special" and "little overpriced" stuff ? Do you shield your cable with breaded copper although it wasn't shielded to that point from the powerplant to your amplifier. You wanna shield the last 3 meters from 1000 miles to make a miracle device ? Above cable 3m : ~ US$ 160. Your amplifier power cable is free, it comes with cable, the $2000 price included the power cable already.

@@telelaci2 I'd understood it's more about protecting the other low voltage cables (e.g. Interconnects and speaker) running behind your system from the EMI noise generated by the mains cable. So shielding is key, rather than super thick or fancy conductors

@@dalevearncombe9672 If that would be a problem, then the electric engineers would simply move the mains to a new position far from other cables. (its not near anyway) IF that could be an issue, they would do that. They would be able to do that, they are engineers, designers, professionals, they know how to design an amplifier, trust them. Btw other low level signal cables are shielded ! Not the mains but the L and R audio. Shielding the mains is very silly idea. Maybe silly is an improper word, because it has its purpose, it's a nice rip off.

@@TechStuff365 Hi John, you just ignore what I said about the mains. It comes from a power plant hundreds of kilometers far away. Via many kind of devices, transformators, switches and at last it reaches your house. The electricity is propagated with the speed of light, so despite of the 1000km it's there in an eyewink, let's say 0.003 second. Inside your house the wire goes inside the wall, it's a simple industrial and cheap copper wire in the best case, nothing special. What can a "high quality" cable improve on that on the last meter ? Use your common sense. The other 1000km long wire's quality doesn't count only and exclusively that last meter will ruin the amplifier's capabilities ? These fancy cables are nothing else but, thick copper wires assembled with high quality plastic insulations and parts, and very beautiful colors, really demanding products. Price is set if it was from solid gold, not plastic and copper. But what is the purpose, 1000km wire's quality is random, sometimes bad, and the last one is good ? Hows that ? And by the way there is no limited budget for the cable, because it's not an expensive part. They make it expensive, because they can sell the snake oil, so why not ? Free money from the snob pigeons.

@@TechStuff365 "Often they are only 5 amp rated, sometimes they aren't even solid copper." - OK, but you have no idea how to calculate the input power at a power amplifier, it was not part of your education. A 7 amp (not 5 but more) rated wire is 22 AWG (at max 47kHz). Most of ethernet cable's size is 22...23 AWG, that is the size of 7 amp rated cable. Everybody knows how thin an ethernet cable is, you just have to check the glassy RJ45 connector. That is the thickness of a the power cable you get, it's your statement. And you think that when you buy a $2000 Power Amplifier, it comes with crap cable, because the electric engineers who designed that amplifier couldn't calculate the proper amps and they will give you a cheap unusable budget thing for the money, not even copper. But you know it better than those engineers. They don't want to give you a good product, they have no competition, you can buy only their amplifier, no choice. No capitalism, no competition. They will save $10 on the power cable and they will live like a happy fish in the water. I think the opposite. Not the power amplifier manufactuers ripp you off with a cheap cable, but the oil snake manufacturers ripp you off with an $500 cable. But: "...its very unlikely there will be poor cables in that chain..." - when you are talking about the 1000miles, so you think every cable piece is good quality except the one that you get with the amplifier. How logical is this ? And by the way the HiFi's problem is only the undersized cable that is heating up ? Your statements are not very well based, I don't want to argue with it. If you believe in this I don't want to change your opinion, it's fine by me.

Thank you John.

I’d probably omit using caps, unless you know exactly what you’re doing for specific components. And even then listen with/without. Power filtering can go sideways.

Not true for W3104 which is rather rated for DC500V/15sec.

learn how shielded power cord is beneficial.

​@@Tharbamar, but you have only a small portion of shielded cable in power line. Don't you think that is not really logic to say this will have any effect?

@@82levy5 yes digital equipments are very sensitive to line noise.

​@@Tharbamar, i have a feeling that you don't understand the point that only about 1.5 meters of cable is shielded, the rest is not. What are you think abou this?

@@82levy5 I too have the feeling that you’re not going anywhere to understand the concept of minimization of noise in audio chain, end of discussion here. Edit: instead of trying to make arguments here why don’t you do more research.(no offense intended)

Yes but regular annual cleaning will take care of that, thanks

@@Tharbamar But does it only oxidise the copper on the outside or also on the inside? Because if not, you always have to disassemble the connector to clean it

I wonder how these compare with his AC12 PS Audio cord he loves so much but he doesnt seem to respond to questions PLEASE answer us !

Wrong! Good cables make a big difference compared to stock garbage even on high end gear.

@@samza9622 Ok, measurements with the most precise equipment and decades of research say otherwise. Some cables do make some differences in some circumstances but the cable in this video is BS. I've had a few and seen them tested, never makes a audible difference. AudioScienceReview and Audioholics

AC or DC current is current, As per Ohm law 1V AC = 1V DC and W3104 is ratted for 500v DC.

@@Tharbamar Thanks, should be perfectly fine I guess. Question is, will an insurance company accept a claim involving Mogami 3104? It is a cable not legally rated as a AC power cable. I checked with my local Australian Hifi supplier and they said NO. Even Furutech hifi bulk 'power cable' does not have the legal blessing in Australia. Besides unless one is a qualified electrician here, we cannot even put a plug on a power cable! I am not complaining, but merely pointing out the issues that one has to consider. Something that can be perfectly good and fine may not stack up legally and have an inherent risk attached to it.

@@Tharbamar Just to add that, here in Australia, all electrical cables need to be certified by Australian Electrical Standards and test tagged. So Mogami 3104 speaker cable will be illegal here. Problem is, even if someone makes it with 3104 and it works fine, you are still breaking the law here! Must be the same in many other countries too. Thank you for sharing wonderful information but although "easy to DIY power cords" viewers should know the legalities. Cheers.

@@melodychest9020 that's fine, its for safety. it would be a shame if your house burned down because of a wonky power cable.

@@melodychest9020 Sounds like a well-intended law that was made long ago and should be changed given advances in electrical technology. This is the sort of practical handyman work that should be taught as part of a public educational curriculum. However, it is important to follow existing laws while petitioning for a change in those laws. Good Luck!

I don't know why you think it as dressing, it's for protection of the copper shielding.

Smarter people, most funny thing. Some people think themselves smarter than others all the time.

@@Tharbamar If you don't think that the Engineers who design these components aren't "Smart". Well I don't know what to say. I still stand by what I said. If the Engineers who designed component thought it needed other than a standard power cord. They would've included one.

Thank you, I was a union electrician for 40 yrs and started in electronics in H.S. I've been trying to explain the AC power at the end of a power cord is EXACTLY the same unless your cord is defective or too small a gauge. And you are correct, the first thing in audio gear is a power supply which changes the internal voltage and filters the DC. The current draw of say a pre-amp is sooo small the cord can be very small gauge. They are very pretty cords tho.

looks nice, costs more, must be better? funny, electrons are not all that fussy, they will flow through what ever they can. copper works the same as pure gold, go figure! lol.

@@Tharbamar "Smarter people, most funny thing. Some people think themselves smarter than others all the time." - Exactly. You and the cable believers are much smarter than the amplifier's engineers and the whole developer team. You know what they missed. They should go back to the university .There are so many st...d engineers in the world jeez.

It doesn’t matter what you think or others think, good cable doesn’t hurt.
