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

[@makatac2629]

Ok so I have been working in electrical & cabling systems for 30+ years & although I am a "non-believer" (that it makes any difference noise wise) I will offer you & others that wish to make their own power cables a pretty good tip, because after all manufacturing your own to a specific length to suit your equipment if it doesn't cost you much will be satisfying (just don't bother with the shielding bit) So when you start with your three wires before you do anything else hold all three together & insert them into a cordless drill like you would for a drill bit, then hold the other end tight (or get someone else for that bit) then pull the trigger on slow & watch your wires all spin together perfectly without any kinks or uneven bits. Then when you apply your outer sheaths & heat shrink it will be smaller diameter & easier to slide the last bits over. One last point...don't twist power wires too tight, just similar to how Tharbamar did is fine.

[@montech5647]

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!

[@makatac2629]

@@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.

have ordered some 4TC cable from China on ebay, it has 8 braided conductors in 2 colours all constructed the same way Kimber build theirs. this allows for no shielding to be required as the 8 strand braid acts as a natural shield. also the construction is like a tunnel that allows you to thread a single conductor through for the earth, it just looks so much neater when finished

[@mateusznowakowski5895]

Hi Tharbamar :) Im your huge fan from Poland. I made a lot od DIY cables because of you. I now want to make this power cable and have question. You said that this cable is made for transports, dacs etc. But what about power amps, mono blocks ? It can be safely use to power amps without risk of overheat? In other video you made AC from 3104 but using all 4 wires but without shielding - which one is better?

Hi there Just made this cable and although it still burning in the difference in the sound is already audible. Thank you so much for sharing the knowledge

[@Tharbamar]

You’re welcome, enjoy!

[@VegasVaron]

Generally it’s my understanding that if you buy a decent component, you can rest assured that the power cord that came with the device will do the job. You don’t have to replace it, unless you want to have a fancy looking power cord and that’s okay too. Fancy power cords will typically not change the performance since AC is converted into DC, and almost certain the manufacturer has installed a noise filter in the component as well. Nice looking power cord though. 🙂

[@NelPieters-Dekker]

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.

[@ronaldmcdonald2456]

Til now I've been like so many people, ''What came with the box gets the job done.'' Recently had some time to kill so I finally got around to building this cable for every box in the chain. 8 of them. So far, I'm warm and fuzzy about it😄. An overall increase in dynamics. The soundstage, in terms of instrument placement has always been good, but, now the instruments feel more solid and articulate. I can just simply hear more, and It is a lot nicer to listen to. If I wanted to spend more for wire what would I get? OCC this time? Though I still want to maintain the same method you've got here, and don't want a finished cable that is already shielded and only needs hooking to the plugs. Thank you my friend!

I want to make new power cables for amplifier, pre-amplifier, 4k BluRay player, CD player, TV and anything else in my home theatre. I see you use 2 conductors from Mogami 3104 wire plus a new ground wire and twist these together. If I want to end up with a 4 foot power cord how long do I cut the Mogami 3104 wire? How much length can I expect to loose when twisting the cables together? If money was no object I would build the Oyaide cables you built in another video. These look more in line with my budget.

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.

You could rip off the outer shielding would be better can replace it with PTFE plumbers tape 4 coatings forward and back, don't go to tight.

Funny, the power supply in my amplifier filters out any noise…. Suppose you have a noisy power supply, than a good cable won’ t help. I don’ t agree with the usefulness of this cable, but you are very good in doing a presentation. A more interesting topic would be to prevent ground loops. Ground loops are very common when you have connected more grounded apparatus to your amp. It gives an annoying mains-frequency noise in your speakers. The solution is to not ground your amplifier via the mains cord so don’t connect the ground in your cable at the amp side. (or safer: use an isolating transformer)

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 $.

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.

[@dalevearncombe9672]

@@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

[@telelaci2]

@@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.

[@telelaci2]

@@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.

I don't have to dress my power cables cuz they are hidden behind the rack.

[@Tharbamar]

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

[@lassalade]

Nice vids. ASR church members got triggered 😂

[@tomekichiyamamoto2177]

Is the AC power cable??? Why shielding it? If you shield the last 5 feet of your AC cable, you should eventually shield alllllll the way long from the power plan, till your house 🤣

[@iowaudioreviews]

OMG 🤣 Anything goes when its subjective. Properly engineered audio gear will perform its best with this cable or the stock cable.

[@samza9622]

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

[@iowaudioreviews]

@@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

[@anemul266]

Seems awful stiff.

[@richardelliott8352]

DIY AC cords, publicly advocated, what could go wrong? Also, have you identified the problem you are trying to fix? while I recognize the craftsmanship involved and the clear purpose of the video, I would never substitute a professional safety laboratory approved AC power cord for something without a tested assurance of fire safety , unless I wanted to unplug it every time it wasn't in use. without taking sides , the idea of audible benefits in this way is controversial, and that fact alone , to me, makes the risk of homemade power connectors unacceptable. and probably uninsurable.

[@MegaThrillKiller]

Say what Willis? Most components run on DC, not ac. Whatever ac comes in is filtered internally and converted to dc. If ac affected the sound or "performance" of any component. Then that manufacturer would include beefy power cables. But they don't. Smarter people have determined that "Standard" ac wall plug cable is sufficient to power a unit. But, if you think it does, well.....good for you. You just bought something useless to brag about to others who don't know any better either.

[@Tharbamar]

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

[@MegaThrillKiller]

@@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.

[@bradt.3555]

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.

[@mergatroid1212]

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.

[@telelaci2]

@@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.
