My buddy was over the other day and we went down to my music room to grab a putter for him ( I keep my putters in my music room haha ). And he was kinda shocked how it looked and what I had. We started having a quick talk about the gear and why I started this and what keeps me listening to music almost everyday in my hifi room. He was astonished the money I have spent said it was a waste. I would spend around 10,000 a year before on eating out and entertaining at the pub and restaurant and it got me nothing really. I explained to him the feeling I get when I find a new album and when in a well treated room it can give such a strong emotional feeling, makes the hair stand up and just think wow. He sat down and I put a track on made him close his eyes and he was shocked. Just putting on thriller by mj just shocked him with all the sounds coming from all over. When people ask me why I love music so much… my reply is goosebumps… constant mission on making my hair stand up and I love it!

I have qualifications in Radio Frequency Engineering. Skin effect is real. The higher the frequency the greater the effect and cable construction becomes more important. Skin effect occurs at audio frequencies but is so vanishingly small that it can be ignored and will have absolutely no audible effect.

[@nickk6109]

I think the audiophile needs to be more concerned with RF sensitivity due to bandwidth of semiconductors - large RF amplification can lead to instability and power consumption that impacts the semiconductor's ability to process audio frequencies. Think of it as your engine working hard for something you can't see, leaving little to no power for driving your car. It makes sense therefore to look at the filtering, power supply decoupling, shielding and PCB layout in the design of audio devices itself.

[@thinkIndependent2024]

Today it's not a problem. originally all HIFI cables were solid not stranded. If we can perfect carrying this new technology of full range audio sent to the ear by laser then it may become a new problem

[@NeungView]

I design high-power AM, FM, VHF radio transmitters for a living. In the real world, we use Litze-wire, which is a lot of really fine strands of copper wires individually lacquered and twisted to make a cable. Each strand is the radius of the skin depth, making each strand "all skin". Using 250 of these (typically) in parallel makes the resulting cable "all skin", saving the need for silver, or some ridiculous manufacturing process to hollow out the centre to save weight/material cost. The skin depth depends on the frequency. We typically use Litze-wire from 500 kHz up to several tens of MHz, with powers from 500 W to 10 kW. Below that, normal wire does not get hot enough to warrent the use of Litze, and above, other methods are more efficient. For audio frequencies, the skin effect is negligible compared to the capacitance between the two wires. In fact it is so tiny that it can be ignored.

I have bumped into the skin effect while listening to music. The music was on the record player in the corner of the lab while I was working on unrelated signals at 800MHz at -80dBm on the bench.

[@GTRxMan]

The skin effect is real but in terms of audio perceptible to the human ear, it's utter bunk. There's no way that the skin effect is causing an appreciable fall off in frequency response. There's not a chance that there is even 1 dB of difference. Chasing after cables to mitigate the effect is simply another way to waste money.

[@usaturnuranus]

I beg to differ - They are not wasting money, they are making generous and voluntary charitable donations to R&D labs the world over, thus allowing the rest of us to obtain better equipment at a more reasonable price point. I think we owe them a bit of gratitude! (/s, of course).

[@Justwantahover]

I build speakers with FR driver and added woofer and use acrossover filter for the FR driver. I found that my steel alligator clip cables sound different to my standard copper cable. I used the steel alligator cables for trial&error connection. But after discovering that they sound different, I no longer use them. I now use cut off bits of my copper wire (without the alligator clips) for trail&error. Less convenient but way more accurate. So cables would have to make a difference. The difference in my case was so great that I had to change a resistor when I changed to my copper wire (after usinging the steel cables) on the crossover.

[@ronschauer839]

Oddly enough I was just discussing this with a friend (also a KZbin audio channel presenter) in the last two days. I did calculations and determined that with the wire being used for some interconnects we were contemplating, the skin effect should have no effects of any reasonable concern until at least somewhere well above 260-300khz. As neither of us are bats (last time we checked anyway), we laughed it off and carried on. 🤣

[@bachvaroff]

"Hearing" the effects of the skin effect at such a low frequency with one's vastly imperfect pressure-to-neuronal activity transducers (ears they call'em) is on par with delusions during a manic episode. It's also an alarm to see a shrink asap, with the possibility of remaining there for treatment…

[@matt-g-2501]

Thanks for this interesting information. As an electrical engineer I did calculations on cables for frequencies above 1GHz. Especially when it comes to high power and high frequencies, the skin effects need to be considered. It saves money as you just need a tube and not solid material. An audio signals might have harmonics up to 100KHz (e.g. a 10KHz square signal has a lot harmonics) but even then, the skin effect is very little.

[@Roosville1]

Two points; at 6:10 where you discuss the effect at 20KHz, being the skin depth is 68% of your conductor. Although noted, it's good to remember that this point isn't a "brick wall", it's the point where 63% of the current is carried, the remaining 37% of current is still below this depth. The effect is therefore less than expected. The other, is the topic of surface roughness, where "how smooth" the conductor surface matters. The roughness alters the the impedance for high frequency signals traveling at the very edge of the conductor. Whilst really a concern on PCB traces, it does have a measurable effect on in co-ax cable. Certainly in the >40GHz range, but that little frequency-detail won't bother the serious audiophile. I give to Audio Phil conductor surface roughness as a new audiophile toy. :- ) And yes, I literally have in the past polished PCB traces….but that’s a RF story. Bum, thats two things for Phil now....

[@willmcgo8288]

At 2:23 "Of course, the effect becomes greater the more you worry about it." - so true! If you are making hollow wave-guides to carry radio signal currents to an antennae in the GHz frequencies, the wave-guides can be built out of something inexpensive and strong like steel that is not the best conductor. Then coat the inexpensive metal with a thin layer of silver, which is an excellent conductor. Due to the skin effect the radio frequency currents are carried in the silver layer. The silver will in turn be coated with something non-conductive to prevent it from oxidizing. This effort is not required for audio frequencies.

[@phomchick]

I have a pair of RCA cables made of Litz wire which I made about 40 years ago. I know where they are, but it has been decades since I’ve used them, because I now know what I’m doing and I’m sure it doesn’t make any difference.

[@slevengrungus]

Guitar cables are subjected to an effect that can seem similar to the skin effect if the cable becomes several meters long, and you will then hear a clear decrease in brightness, a good countermeasure to this problem is to plug it through a buffer that converts the signal from high impedance to low impedance, and it will be capable of retaining those frequencies through said cable. By the same logic I would think active pickups would completely remedy this problem before even reaching the cable. the reason guitar cables are subject to this problem is because its core and shielding together can act like a capacitor, driving those higher frequencies to ground. Considering a buffer can retain the quality of a signal across a long capacitor I would claim that an "audiophile grade" power/pre amplifier should be able to retain the quality of a signal though a regular copper cable without any audible issues at all

[@kevingest5452]

That isn't skin effect

[@slevengrungus]

@@kevingest5452 yea its not. the skin effect is an inductive effect. The guitar cable is a capacitive effect created between the cable's shielding and its core, leaking higher frequencies to ground, thus dulling the sound before reaching the amp. The reason I said they can seem similar is because they both result in loss of high frequencies proportional to its cable length. the guitar cable is just way worse

[@klaushaunstrupchristensen7252]

It is a sad state when audiophiles worry more about skin effects rather than the Fletcher Munson “equal loudness contour” and the implications. John Crabbe once wrote an article in Hi-Fi News where he first went to a concert of a Mahler symphony bringing with him a spl meter. Afterwards he went back home and played the same symphony at what he felt was the same volume. It turned out that it actually was 10 dB lower than the concert hall level (quoted from memory!) This really makes questions like: which frequency response do we really need/want in a playback system where we potentially play at a much reduced level? Much more relevant compared to questions about how much skin effects reduce the level above 200 kHz. Thanks for sharing and greetings from Denmark .

[@Lif-999]

In my experience, any percieved differences [usually HF loss or even hum] in cable performance is due to poor or failing cable/connector interfaces. EG. bad solder or crimping points. I am confident that at audio freqencies in double blind tests, no one would be able detect differences in cables due to the skin effect alone.

There are some speaker cables which work based on skin effect. I use the $1400 ten feet long Silversmith Audio Fidelium speaker cables, which totally depends on skin effect (which tries to maximum surface area, with strands which are less than a thousandth of an inch thick). I use these on a system which costs over $100,000 and see no reason to get a more expensive set of speaker cables. When I upgraded from a set of 10 foot long $1300 Transparent Musicwave Super cables, I found the improvement to be very dramatic. Of course, if you only have a $1000 system, you might not notice any difference.

I find that people tend to to have pretty rigid beliefs. So much so, that there is a saying in some research fields: "For those who say that it can't be done, get out of the way of those doing it!". I remember back in the late 80's hearing about the differences in US versus Russian Space Shuttle design. The burn patterns from re-entry of the Russia space shuttle wasn't possible from US understood science. This suggests that no matter how smart people think they are, they aren't necessary right (which includes me). They believe themselves to be right and won't examine something if it does not fit their existing world view. The problem is that they can miss out on a lot of potential benefits.

It seems to me that music/audio is at its optimum state when it is being mixed or mastered in the studio. The mix/master engineers are really the only people who get to listen to the audio in its purest form. From that point, the rest of the world has to listen to the audio, which was finalised in a studio, using equipment and acoustic treatment that is different to that of the original studio. Surely audiophiles should be trying to replicate the exact conditions to be found in the studio, worts and all, and that means using the same box standard interconnectors. Or am I missing something here?

My comment was going to be something about the skin effect on braided wire, but you acknowledged it at the end with some sarcasm. Thank you.

[@christopherward5065]

The frequencies of electrical signals being applied to a wire is very narrow in range compared to what a wire could propagate as a signal. I would say that wires do work through creating a magnetic field around themselves when they have an electrical potential difference between the ends. The field can be modulated in frequency at frequencies that can do work with transducers such as microphones and speakers modulating a current. The modulation of the field around the wire makes it able to affect its environment and to do work on materials and circuits nearby. There will be some loss of energy from the signal via the field into the environment but probably only a negligible amount of loss at audio frequencies. Increasing the frequencies by orders of magnitude would increase the proportion of energy lost through the wire’s field, as the wire tends to become a radio frequency transmitter. At audio frequencies there would be very little loss over the frequency range. Cables tend to be made of collections of wire strands so the effects are more about metallurgy, arrangements of the strands, strand diameters. These are more significant variables in audio cables. Most manufacturers are juggling these variables.

[@Douglas_Blake_579]

And here you have the reason I've been telling people that thinner cables are better for interconnects. It's painfully simple... at audio frequencies the skin depth in copper is greater than the diameter of the wire... so the whole thing is used. The same is true for speaker wires... at 30khz the skin depth is like 95% of a 16ga lamp cord and since it is stranded wire, this depth is greater than each strand, so eddy currents are greatly reduced and you're only messing with 0.004 ohms of resistance per foot. Now if you want a REAL reason not to use horse-dong sized wires, consider that *surface area* is a grand multiplier of the cable's potential to pick up stray signals. Take any antenna and double it's diameter and watch what happens to your signal strength meter... bigger wires make better antennas. But hey... I'm just a lowly technician, what could I possibly know....

Yes, skin effect is a thing.... like most disinformation, they latch onto a grain of irrelevant truth and twist it in order to manipulate us. I can remember from my days as a US Navy radar and radio technician, Skin effect is the reason we use waveguide for Radar signals, but not for Hf (3-30MHZ) Radio signals because it's negligible... irrelevant for signals that are 10 times the audible frequency, so the frequencies we can hear aren't even 1/10 as high as they would need to be for skin effect to matter.

[@brannonmcevers1854]

I think one should definitely be concerned about the copper cables and PCB's used in audio production. After that we can obsess about the 50 or so dirty opamp sections used in music production electronics...

[@offbeatinstruments]

I used to work for a company that used skin effect to look for cracks in metal joints that had been subjected to bending forces. Essentially you send a high frequency signal through a chunk of metal and measure the voltage drop between two points. If there is a crack the current has to travel further (down and up the crack) and you can measure this. Bigger the crack, the bigger the voltage drop. So there is another thing to worry about (or not) cables with cracks in the surface layers with present an even higher resistance to high frequencies. So now you need cables that have never been bent.

The "skin effect" this going to be a touchy subject. So how about throwing a can of worms onto it. I've got news for all....the powe from sorce(amplifier)to the receiver(speaker) isn't transferred through the electrons in the wire. The electrons are more like excited sheep bumping into each other in a tunnel. They are reacting to the electromagnetic field generated around the wire from the sorce and receiver. The power is actually a vector going from the sorce directly to the receiver (more like light and at the speed of light) traveling in the electromagnetic feild defined by the sorce, wire and receiver. So like those sheep the electrons are actually robbing power from the system by bumping into each other and dissipating it as heat. Sorry Phil 😢😂. The bottom line is the wire needs to be big enough for the number of sheep and the insulator strong enough to contain them ... and yes a few are going to get away in the chaos as long as that is kept so a few in the overall picture...

Now I may be slightly off on the physics (it has been a few years since I actually did any maths on analog signals in wires), but ponder this: If we compare the propagation of an audio frequency signal through a solid wire of say copper and compare to the same signal through a silver plated wire. With a well chosen diameter wire, the skin effect will be negligible even at the upper end of the audio spectrum through the solid wire. Now introducing the silver plating. Would this not exacerbate any skin effect due to the lower impedance of the literal skin, the plating of the wire? I would not be surprised if such a cable would be even detrimental to a signal passed through it. This area is so filled with near religious beliefs that it’s hard to find good, scientifically sound (pun definitely intended), information on the actual behaviour of a signal in in a cable in the relevant frequency range.

to minimize the skin effect, simply use a copper cable with (many) more thinner copper strands wound together into a 'fat cable'.

[@techcafe0]

litz cables i think have many hair-like copper strands, all electrically insulated from each other (each strand is coated with shellac or something, i'm not sure), then individual strands are all soldered together at each end; forming a thicker cable that, suppodedly, minimizes AC resistance / reactance at higher frequencies. whether the skin effect is actually perceptible within the audible range of human hearing is another matter. first time I saw litz wire used was in a pair of Sony earbuds.

[@jonathanlake6053]

As they say you pays your money & takes your choice, I enjoy the sound from my silver interconnects,but I have never been convinced that a silver wired mains lead would make any difference.

[@Justwantahover]

What about those wide flat cables like 3" wide? Are they brighter?

[@greenmanreddog]

Has anyone ever considered using 15mm copper pipe for speaker cable? This would eliminate the skin effect completely as the only conductor is in the skin.

[@connorduke4619]

Yes but that could be sold for $25 per meter and would undercut the entire cable industry!

[@willmcgo8288]

With the added benefit that you could run coolant down the core, and keep the conductor cool and push higher currents without the conductor getting hot and increasing in resistance, thus preventing additional power loss in the conductor. Probably best not to mess around with the potential for flooding, and leave the liquid cooled cables for fast-charging electric vehicles and underground extra high voltage cables on the electrical grid .

[@artysanmobile]

Wire has inductance, multi-wire also has capacitance. These quantities can be measured and the frequency response of any given wire can be calculated. Professional wire companies, as opposed to audiophile wire companies, include these specifications for every product they sell. We design engineers appreciate and take full advantage of such professional behavior as we can choose the best solution for every application. In all my years of such work, skin effect has received virtually no attention. Why? Because it has been measured and shown to be inaudible. Belden, as you mentioned, is very serious about its business of wire. Their products are expensive but competitive and exhaustively developed for each application with complete technical specifications. If skin effect had any audible contribution worth mentioning, you can bet they would do so and offer a product to mitigate it. Notably, it does not.

[@BrainHurricanes]

The higher the frequency, the higher the resistance (impedance) from your speakers, so the skin effect is absolutely nothing to worry about in comparison. As a silly comparison, say your speakers impedance rises to 100 Ohm, the skin effect would add 0.0001 Ohm on top of that. I'm sure someone can come up with the correct numbers, (but still negligeable).

I'm not sure what point you're making by comparing the 0.8mm cable to the 3mm cable with 685 skin effect. 100% of a 0.8mm cable is 0.5mm^2, but the outer 68% of a 3mm cable is 6.3mm^2. So, even taking skin effect into account, the 3mm cable still has a much higher effective cross-section (i.e., much lower resistance) than the 0.8mm cable. (No, I'm not an audiophile. I can't hear anything. I haven't spent money on anything.)

[@TheEulerID]

The statement that thicker cables are worse for skin effect is only true in the sense that their proportional increase in resistance to skin effect is higher. However, if the absolute effect is lower. That thicker cable will still have a lower resistance at higher frequency than will a thinner one. What matters is whether it is significant or not. If the input impedance on a loudspeaker at high frequencies is low, say 4 ohms (unlikely) , then an increase in resistance over a couple of metres of audio cable of a few tens of milliohms (at worst), will haver zero audible effect. A thicker cable will simply not make that worse (indeed it will be better, scaling by the wire radius, not it's cross-sectional area). For signal cables, with input impedances measured in thousands of ohms, then the skin effect is utterly irrelevant. The only type of audio engineers who need to concern themselves with the skin effect are those working in giant arenas, auditoriums and the like, when a large number of other factors also come into play. In any event, in the unlikely circumstance that the skin effect is important at audio frequencies, then the solution is to mover the power amps close to the speakers.

[@titntin5178]

Maybe I'm a different kind of audiophile, but all I'm interested in is how it sounds and how it communicates music to me. I guess there are a ton of snake oil salesmen who may well spout some of this stuff to try and justify pricing but unless they can definatively measure why something sounds so good to me, its just hot air, it will sell on how it sounds. Same for those who think we can definitively measure everything and confidently declare it doesnt exist unless they can measure it - such as the stalwarts at ASR. Are they really saying other earth like planets never existed until we got the tools to observe them? I will continue to use the measurements we know about, but most importantly, my ears to judge what I like and what seems worth the spend. Maybe a few of you would already consider me to be well down the Rabbit hole - I just spent £330 on speaker cable. I didnt spend because of technical mumbo jumbo, but because they sounded like a big improvement to me, and results are everything to me, subjective or not.

[@kensmith5694]

For you grounding consider that 20KHz goes several meters deep in the typical dirt. This means that your system ground is very well connected to planet earth if you ground all your audio at one point. Grounding can reduce hum pickup. The filters required to meet FCC generally mean that your whole audio setup ends up at about 50V vs planet earth, In the days of tubes, this was hard to do on any sort of budget. Today, transistors are basically free. An engineer can throw 10 more of them at a design if needed and not increase the cost more than the cost of the power switch or volume knob. "brighter" and many terms like that are very poorly defined. They are generally not well defined because in many cases the effect is pure imagination. Modern audio gear has a very flat gain and a near constant time delay over the audio band. For low impedance a 4 wire braided cable works better than two twisted conductors. If you braid two red and two back #14 wires together then parallel the same color wires, you will get a lower impedance than with a twisted #12 pair. Ribbon cable can work to get a cable under a rug. With a 100 wire ribbon you can use every other vs the other every as a speaker connection.

I would put cables and connectors in first place in terms of influence on sound, after a high-quality speaker system. There have been discussions on this topic for decades, and it's a shame to waste the time of people who haven't already, especially those who listen to jazz and classical music, where it really matters. The main thing is to buy from trusted sellers, do not take risks. It is worth noting that amplifier components are also conductors with only a specific function. For me, everything was decided 27 years ago, when I bought my first American power cable from a famous brand, I was shocked by what I heard! Thanks to the masters who know how to do this! Warming up to 500 hours is also important, in the process the bass will disappear and other distortions will appear, the result is worth it!

[@MarkThomas-hm3ju]

Hey, with the new technological advances made theses days, maybe a speaker cable could be made using a crossover which would shunt the high frequencies to the center of a multi metal layered design whereby the center section has been made favorable for high frequencies. Wealthy audiophiles could rest then.

[@AudioMasterclass]

Audiophiles never rest.

[@matthewloughlin1943]

I'm not an audiophile, just a HiFi enthusiast, the thing about cables always irritates me, I have seen insanely expensive cables that are of exactly the same construction as far far less costly items. Whilst trying loads of different cables to my speakers, none of them costly, I noticed that tinned conductors sounded better than plain copper, no Idea why. Could some small part of the audible improvement be ''skin effect''? being reduced? I am making a leap of faith here but I'm just curious.

'Audiophiles' do not spend $1000 on interconnects because it improves the sound- it does not. It is a form of religious tithe- the high priests have convinced them it is necessary. The greatest improvement comes from better speakers- but your wife notices those. Sneaking in a piece of wire is easy, and anyway she would not believe what you paid for it... Reminds me of folk that buy 7000 strand speaker cable, seemingly not realizing that, inside the cabinet, it likely goes through a long length of single core wire- an inductor in the crossover.

[@arvidlystnur4827]

I doubt any expensive woo woo line level, low impedance cable or silver fancy speaker cable would sound or scope any different then good grade low capacitance coaxial or good grade 10 or 14 gage copper wire, in a blindfold test. I remember wiring two speakers at a party, one channel cheap RadioShack 20 gauge and the other a 14 gauge camping extension cord 20 ft lengths. The RadioShack side sounded like the tweeter was blown. I scrounged around and found some expensive 14 gauge speaker wire, then used it to replace the twenty gauge stuff. Funny thing, even switching the amp to mono, no one could hear the difference between the expense 14 gauge speaker wire or the camping 14 guage cord! ElectroVoice has tables on what gauge to use for differing applications of speakers. Short run wires, low volume efficient drivers 16 gauge may be sufficient. Long run, 25 ft, loud inefficient driver between 10 to 14 gauge wire, probably is necessary. If 14 guage copper just gets the job done, 10 won't improve it, and 16 gauge silver won't get it done.

As we know most current is carried on the skin. The way to resolve this is to use hollow conductors...... Like they do in electrical substations.....And some transmission lines. And no - I am not joking. Look it up. Hollow conductors save money on material. I'm sure the Hi-Fi manufacturers will be able to parlay it the other way and charge more for less as they will claim it is better! 🙂
