As long as the cable is made of Copper and isn't too thin it will sound perfect. A 1€/m cable will sound the same as a 100€/m cable, as long as it fulfills a certain minimum critera.

@@rolandrohde Indeed. I have conducted my own blind test on my hi-fi using Van Damme cable (a good quality, reasonably priced copper cable) and another brand (£12.00 per metre) and I could tell no difference whatsoever.

@I was with your mother totally agree. I was justifying the cost differential between good and bad quality copper. Not debating whether the quality of sound would change significantly to justify the cost.

[@sirmalus5153]

I once tried a set of Siltech speaker cables against a set of DNM ribbon speaker cables. The "upgrade" too the Siltech cables cost a couple of thousand pounds. It sounded rubbish. I went back too the DNM cable, which (then) cost around £40+ a stereo 2m pair. Fortunately the Siltech were on loan, so no money was lost by me. The "problem" was the Siltech cables just didn't suit the amp and speakers I was using, but the cheap DNM cables did. the Amp was an old Rogers A75 (remember them?) and a pair of Spendor SP1 speakers. I have since gone on to a Conrad Johnson MV55 valve amp, a Meridian 808 CD and Spendor S100 speakers. All connected with Van Den Hul interconnects (The Second) and their speaker cables (Revelation) The old DNM cables now don't suit the system, but I still keep them for old times sake. They would however make the current system sound lacking in weight and clarity if used and somewhat bright, but hey ho. It took a lot of money to find better than them in the end. The old Rogers amp still works too.

Electrons do not bash into each other, in some kind of microscopic Newton's Cradle manner. There is such a thing as electron drift velocity - it's dependent on current and also wire diameter but a typical figure is about a tenth of a millimetre per second. Energy is delivered through a conductive material by dint of an electromagnetic field. A conductive material is that in which such a field can exist. That's how transformers are able to energise a secondary coil (or multiple secondaries) even though the coils are insulated from each other. I don't like being a party pooper, but the information presented here regarding the fundamentals of electricity flow simply isn't correct.

[@MoltenJules]

And it is an AC not a DC signal too which is sent to the speakers.

In fact, the electrons don't move at all! A common misconception. Current is the transfer of a magetic field or wave. 😂 If electrons moved from one atom to another that would entail ionization of the atom. What electrons do is wiggle. In a conductor current flows from where there is more wiggling to where there is less😂😂😂 Our concept ef electrons moving from one place to another is just a convention rather than an acurate description of the actual physics involved.

Came here for the comments, love them. Didn’t watch the video yet. I will say, when you look inside a tower speaker ( a have the respectable Rega R7), there is about 4 feet of zip cord ( or something similar) that travels from the binding post to the drivers. To think the 8 feet of external speaker wire makes much difference is pretty funny ( unless it’s very thin aluminum or something). But for some reason my friends still looked upon my good quality but fairly inexpensive cables with disdain. So I made my own, dressed up with nice ends, shrink tubing , and braided sleeves. Thinking I finally invested in higher end cables, They swear it made a difference. But it didn’t. Eyes play tricks on our ears.

It is even the opposite. Electron repel eachother since they have all have negative charge. What actually happens: The electrons jump from the shell of one copper atom to the shell of another one where a "hole" has been created because that atom also had an electron that has jumped. The electrons are moving from - to + The "holes" is what we call the current, and move from + to - Cables do have an effect on the current that they are carrying. There is resistance, capacitance and inductance and skin effect. The capacitance and inductance in a normal speaker cable are so low, you can just ignore it for audio frequencies. At most, it will attenuate higher frequencies, but never to the extend that it will be audible. This is an educated guess, I did not take the time to calculate this. The resistance just attenuates the signal, and doesn't change the sound. The volume knob will compensate for this. Skinn effect again can have a very small impact on the highest frequencies, but virtually inaudible. Audioholics have some calculations on their site for sure. Of course a speaker voice coil can change the sound. It is a coil, so a high inductance, and together with the filter, I guess you can create an unwanted resonance frequency.

[@PearlAcoustics]

[@buskman3286]

Years ago McIntosh used to do 'traveling labs," going from city to city. They would check your old amp if you brought one in. In those labs they would compare various speaker cables and ask listeners to identify when better cables were being used. The listeners did not know which cables were being used. There was no consistency in selecting between cables - from standard 18 gauge zip cord to "audiophile" cables. This proved to me that the whole issue of "better sound" with expensive cables is marketing - if you can't SEE that the expensive cables are being used, you can't "hear" the difference.

[@PearlAcoustics]

Hi thanks for your comment. I get your point entirely but I want to add that some manufacturers set out to make cables that sound different (and it’s quite easily done) but I personally prefer to keep things clean and just use plain, good quality multi strand copper.

[@Unicorn-ST]

I agree. Any decent cable is probably indistinguishable from another decent or even extraordinarily good cable, but a bad cable could ruin the sound. The balance is to get a decent one at a reasonable price.

[@williamwinecoff1779]

Where do you get your copper cable? If I heard correctly, you said there are 80 strands wrapped in rubber. In the USA on internet I have not found any copper wire described in this manner. Only gauge is given and it seems PVC plastic is the wrapper of choice with rare mention of silicone. Should contact with plastic be avoided? Thank you.

You make an interesting point Rainer. When I am in front of a chamber ensemble, I often listen with my eyes closed. The funny thing is, when a small ensemble group, play together in an acoustically well balanced hall, there is no ‘soundstage’ as such. the sound of the instruments merges together. But with our eyes open, we can see it. What we achieve in recordings, is to create a soundstage that helps us at home ‘see’ the musicians in front of us. Of course it’s an illusion.

Hi, thanks for your question. In fact that’s what basically happens with active studio monitors. Personally, I don’t see a challenge with loudspeaker cables, in as much as the impact on sound with them is very, very small (unless a cable manufacturer deliberately sets out to bring a change about). So as long as one uses a sensible gauge and good quality copper the usual lengths used in domestic situations is not an issue. But your solution is valid, none the less.

Instead of the voice coil example I suppose he could have said he could got better gas mileage when he changed the tread design on his car tires, or simply rotated the tires. Moral of the story or point made, he starts his speaker cable talk. Obviously there is no correlation between tires/gas mileage and interconnects or speaker cables, just making the point that small changes anywhere (tires, voice coils, cables, or whatever) can yield beneficial results. That's my take on what he was saying anyway, and not so much about what tire tread (or a voice coil) has to do directly with speaker cables.

I came across your video series recently and have truly enjoyed your approach to hifi audio. Which may be one area of discussion that carries more opinions than it is possible to count. My background is electronics and I too learned the water pipe model reference as a way to understand the dynamics of current and voltage within a circuit. LOL, I think it all started with how the instructor approached his discussion of Ohm's Law. However, what came soon thereafter was a discussion of the physical properties of wire and current flow (electron vs hole flow anyone?) and two distinct properties stuck with me over all of my years (now 65 of them) and those are that a wire is a component, just as a capacitor, resistor, inductor and that all wire has properties of these three values. Those values become more important with the length of the wire and/or the frequency of the signal being carried by the wire. The deep physics behind your simply elegant explanation lives and breaths. My mind immediately went back to two things that I have always considered with cabling. 1) Strong tight physical connections are critical to performance and safety in high current applications. 2) Surface volume of your cable directly influences (for better or worse) its ability to carry a signal unadulterated. Or at least to the extent possible or necessary. Your in house made cables address both of those core parameters along with the separation of the +/- cables to avoid environmental contamination. Quality of the materials is in my opinion a given, considering your customer base and your personal expectations.

Not saying that the design changes did/didn’t make a difference , although it’s counterintuitive as it would mean hearing the a mechanical difference introduced by microscopic fractions of current within the sea of distortion that the worlds best transducers are.

Which when twisted is about 6mm thick. This equates to an AWG rating of 10. Because the resistance of this cable is extremely low (0.0033 ohms per meter / per cable which only 3,3 ohms for a cable 1km long, then it does not technically make any difference if you use cables of different lengths, as electricity flows roughly at the speed of light! However, most of the time we just accept the fact that on one side there is a surplus of cable. how much difference in length are you proposing?

[@acj2789]

Saying that electric current actually consists of electrons 'bashing' into each other doesn't explain why electrons don't pour our out of the free end of a wire if you connect the other end to a battery. The reason electrons don't pour out is because there's no difference in electrical 'pressure' along the wire until a complete circuit is made, and the circuit contains a battery (or equivalent). You need the (electrical) pressure gradient along the wire to make the electrons flow, just as the dishwasher hose needs a pressure difference between the ends of the hose to make the water flow. In some ways analogy with water isn't as ridiculous as suggested here, although of course it's imperfect. The electrons in a metal such as copper can be divided into two sorts: ones attached to particular copper atoms, and others that are dissociated from atoms and free to move. The dissociated ones, being mobile on the large scale, carry the current. The dissociated electrons are somewhat like an incompressible liquid in the sense that they don't clump together in particular places (at least, not at the frequencies encountered in audio).

Too far above my spend-grade. When I had the walls open in our fixer home back in the 1990's, I used 16 gauge stranded copper wire from a 250 foot roll to wire-up the house for stereo. It still works just fine over 25 years later. Should I start to lose sleep about my future stereo listening situation?

Absolutely not! Enjoy your music. Stranded copper, as you know and prove, works just fine.

[@christopherward5065]

As you explained, there is a lot of difficulty in reaching a balance between the main variables in a loudspeaker cable that make for a believable sound at the listening position. A lot of what we get out depends on the magnetic field the alternating signal current generates, alternating the positions of the electrons inside the metallic crystals in the wire filaments of the cable. Then, it’s a consideration of how those myriad magnetic fields in each metallic crystal interact with the magnetic fields in adjacent crystals. The magnetic fields do work on each other and together generate a general magnetic field around the wire that moves any nearby electrons too and, according to how any electron was moving when it met the change in its local magnetic field, electron movements can actually be antithetical to transmission of the signal that is modulating the electrons’ positions. The wire ends up as a system where the signal current modulating magnetic fields creates many more magnetic fields which induce many more different currents. The longer the wire gets the more entropic the movements until the modulation is finally masked and the signal is no longer discernible. The system is not at all simple or pure in reality and, only a proportion of the intended signal remains to do useful work at the drive unit, as a magnetic field around the voice coil. The wire is also an aerial and creates part of a tuned circuit that can take radio frequencies back into the amplifier. I like how you addressed the problem by creating a reference cable to act as a known starting position for Sibelius’ neutrality. Cables behave predictably as part of the system they’re in.

[@HandbrakeBiscuit]

@@janezzumer1639 Hello Janez. I heartily recommend making your own speaker cables (in fact I recommend making all your own equipment, but one step at a time, eh?). Wires being twisted around each other are very common in internal wiring in audio equipment and in network/telecoms cabling too, but less common with hi-fi loudspeaker cables, as I'm sure you've noticed. One reason wires are twisted in small signal carrying wires inside communications equipment is mainly to make sure that any electromagnetic field that impinges upon the twisted pair induces a potential into each part equally - so the signal, which is the difference between them remains unaffected. The 'complementary' reason for the twisting is so that one signal wire can't put it's field onto an outside component all on its own without it's 'buddy' being there to cancel it out. There's a third reason for twisting, due to the shape, but before I mention that, so far I've only been thinking of small signal conductors - like inside a preamp or the input wiring of a power amp. Twisting wires is really important here because any unwanted signal that gets induced onto such wires is just about to get amplified along with the wanted signal. Speaker cables come after the amplification has occurred, and so the signal they carry is much bigger and noise that is induced in them would represent a much smaller fraction of the wanted signal (higher signal/noise ratio). So it's less important/necessary to twist speaker wires together (although as the very effective video you linked to demonstrates, the speaker wires themselves could perhaps put noise onto something else if they're separated). The third reason for twisting the cables is that once twisted, they are no longer parallel to each other, so the signal in one wire isn't trying to induce a signal in it's counterpart. They're actually 'constantly' crossing each other at an angle (it's hard [for me, maybe not you] to visualise but it's similar to being able to see that an orbiting body like the ISS is constantly 'falling' around the Earth, the two conductors are similarly constantly crossing at an angle). Having said that, the central spacer section in the insulation on many speaker cables (that give it the 0-0 cross section) will separate the conductors enough to lower their effect on each other significantly. I suspect the reason most manufacturers make speaker cables in parallel runs is that it takes less raw material to get from A to B if you go in a straight line (the Roman road concept) and twisted cables need a longer length of wire. Cable manufacturers are in the business of turning cheap(-ish) metal strands into much-more-cash-than-it's-worth. You could perhaps make your own cables as a parallel pair to start with, then twist them after a while as a Mark 2 version - I used a factor of 1.6 times the length I wanted the final twisted end-product to be when buying my 'raw' wire for my own speaker cables. In hindsight that was probably a bit generous, but I couldn't run the risk of them being too short... Keep your terminations clean and tidy at each end, good luck, and enjoy... :D [Edit: restore a chunk of a sentence in the middle that somehow disappeared]

I believe that speaker cable can make a difference. However, the reason is not the one that most people presume. Usually the difference is quite subtle, which leads to arguments. It can also be inconsistent, which leads to all sorts of mysticism about matching and tuning by ear etc. I suspect that the root cause of all this is in amplifier design and the fact a speaker cable is not simply a low resistance connection between amp and speaker terminals but also adds in some inductance and capacitance that appear across the amplifier terminals along with the speaker load. I once had two amplifiers I was playing around with and I also had two pairs of speakers and two lots of cable. Rather than getting a subtle difference when trying different permutations, I got obvious gross misbehaviour of one amp with one cable that was fine with the other amp and vice-versa. Each amp was obviously distorting with one cable while sounding very good with the other. The differences were opposite and not subtle. This made me believe that in other circumstances there could be real but more subtle differences experienced by people swapping cables around and one person's great cable could be disappointing for another person. One speaker pair was my very good main set only a few meters from the amplifiers in the living room. The other pair were quite a bit further away in another room and quite good but nothing special - the kitchen speakers. I had some ordinary figure 8 lamp flex as the speaker cable for the remote set and I had some fancy, silver-coated, audiophile-branded cable for the shorter run to the main speakers. The figure 8 cable had the two conductors running close and parallel to each for a long distance. This made the cable also a capacitor across the amplifier terminals. One amp was stable into that and the other wasn't. The amp that had a problem with a long run of figure 8 lamp flex was fine with a shorter run of the same stuff. The audiophile cable was completely separate single conductor cables that ran along with quite a bit of separation between them - little capacitance but adding some series inductance (even a straight wire has some inductance). The other amplifier did not like seeing that load but was fine with any amount of figure 8. The fix was quite easy. I put a Zobel network between the speaker terminal and the start of the cable. A zobel is essentially a simple passive crossover such as one might have in a 2-way speaker between tweeter and woofer except that the crossover frequency is set well above 20kHz. The low pass side sends all the audio frequencies to the speaker while the high pass side gives ultrasonic frequencies a simple 8 ohm resistor as the load. The amps sees a more well-behaved load. Many amplifiers have such a network built in but some don't, perhaps to give better looking specs such as very wide bandwidth, well beyond the audio range. A better design, as many have, would be to add this simple network on the output inside the amp, ensure that the amp has a known, designed load at ultrasonic frequencies and it would be more immune to differences of cable or even quirky speaker loads.

[@PearlAcoustics]

Dear Peter, thanks for your contribution to the topic. Much appreciated

[@pete9421]

I found this really interesting thank you. I would just also point out that a set of loudspeaker cables are an inductor, a resistor and a capacitor. These effects may be more important than the grouping of electrons (or maybe I am wrong). I use standard UK twin and earth for loudspeaker cable. I was going with the idea that current carrying capacity was important. It sounds good to me. I know some people will disagree here, but try it out... fit twin & earth and see what you think of the sound.

[@PearlAcoustics]

Absolutely correct. Your solution is very cost effective and sensible.

[@jamiermathlin]

The water pipe analogy would be the same as having the end of the cable connected to ground, having an open pipe is the same as a grounded cable, if you had a stop on the pipe you would have the same analogy as an open circuit cable ! Unfortunately, you have done little to settle the controversy over speaker cables. large cross-sectional area quality speaker cable (12SWG for example) has little inductance or capacitance, and you cannot compare voice coil dynamics and frequency response to an ultra-low impedance cable. Agreed if you compare bell wire with a good-sized quality cable there will be a difference, but spending more than a few dollars per meter on speaker cable is completely pointless, it's all about impedance, as the inductance and capacitance are negligible. Sorry to disagree with you, but I am an electrical engineer with 35 years of experience and I have also been into high-end audio for 20 years, trust me I have tried all sorts of solutions, and there is little basis in spending 100's dollars on cable, you are wasting your money. the majority of claims I have seen and witnessed rely on the placebo effect. My advice use 16-10SWG (1.6-3.25mm) good quality audio cable priced at 1-2 dollars per meter and you will achieve 99.99% of what you are aiming for. Your pre-stages, DAC's. amplifiers and speakers and room! will have far more impact on the sound that you are producing, than cables ever will !

Dear Jamie, thank you for your excellent comments. I absolutely agree with you fir the most part. And I hope I don’t give a different opinion. I wanted to emphasis that everything else is more important that the speaker cables and these should be looked at last. I am completely in line with your view on the cables themselves and our cables are not magic, just high quality, thick cables that we sell at a price that reflects the costs of the limited production run, handmade effort that goes into them. But we are often asked what cables do we recommend and we say thick multi-strand. And some people want to know what cables we used during the development process. I was surprised, however, how some proprietary cables changed the sound and I realised that this could have only occurred by them deliberately changing the capacitance, inductance, and or resistance within the cable.

Hi, thanks for your comment. Firstly, let me repeat what I state in the video. There is nothing special about our cables. Except that they are of high quality, sit nice and flat on the floor, have a low capacitance, low resistance and consist of 80 strands of copper, each. When we developed our loudspeakers we had to decide what to use as a reference point and we chose for multi-strand copper because we knew everyone could get hold of it easily. It is very easy to make a cable alter the sound, all you need to do is add capacitance into the casing, or make it resistive, or induce an inductance (or a combination of all three). Some manufacturers do this to make their cables sound nice. Because the amount they alter by are usually very small, it can be hard to measure, but not impossible. Hoping this helps?

When we record bass drums or acoustic basses, we use very small diameter microphones. Hopefully one day you will hear a pair and see what we have achieved. Another point of interest can be that many subwoofers use small diameter drive cones… and to excellent effect. Even though we don’t think the Sibelius needs one.

I have a reasonable quality collection of components and like many, it's tough to get the sound exactly how one prefers it. I have tried a few different brands of interconnects and speaker cables over the years, and with higher end, more sensitive equipment, cables make an obvious difference to the sound due to capacitance, inductance etc that makes components react differently to each other. It's mostly a crap-shoot getting the right mix, but when you do it's certainly night and day and I used to be the guy that laughed at people that praised the cable voodoo. It's more science than fiction, and it's doesn't necessarily take expensive cabling to get the desired effect as I recently found out.

[@healthylifestyle3427]

With respect, that makes exactly no sense and has never been proved. So if you did indeed heard difference (which no one ever proved), no engineer (no electric engineer nor sound engineer, no music producer for that matter) could make sense of what you heard and why. So how would someone come up with a 'technology' that is making clear changes in sound quality, if it is impossible to conceive it nor to test it? It really must be magician working at it. Would be interesting to wonder how come audio component are so sensitive that they produce impossible things to measure nor explain but video doesnt have any of those issues. Nor does the equipment at the ER, or in a science lab in a university. Only your speakers for your hears. Wild. Anyway, if you enjoy your speakers, that is all that matter!

It's a shame the cables have a white rubber insulating core. I find a light blue works best with rubber, especially on a Monday, although sky-blue-pink seems best for PVC covered cable, but it is in short supply, due to Covid 19 and the cold weather in Canada. Looking at the cost of most 'audiofool' cables, it is also cost-effective to braze pound coins together to create a nice, sturdy cable, although they are a trip hazard to small children and giraffe's....(polish your coins first, though, as the skin effect is a real issue at higher frequencies) 😉

I will tell you a secret... in our listening room we have had quite a few different rca cables, from very expensive (gifts from people wanting reviews to very cheap ones, including ones we bought ourselves, and the ones I like the most are ‘Amazon Basics’ they are very smooth sounding and yet still detailed. I think they were less than 10EUR a pair

[@jerrypartington3650]

The type of music cannot possibly affect a cables performance, or any other component in an audio system. The choice of music is subjective and purely in the mind of the listener. A good component or system is by definition capable of achieving accurate reproduction, regardless of the input signal. If a component or system is perceived as being musically inaccurate, it will be with all and any music it reproduces. Subjectively a listener may tolerate this inaccuracy or even be unaware of it, nevertheless the system or component cannot possibly alter it's performance depending on the nature of the signal. A music signal has only three components; Frequency, amplitude and phase, which have absolute values at any given moment, if we imagine an audio system as a measurement device, the potential for error given that these values are constantly changing is clearly enormous.

[@ChristopherWoods]

@@jerrypartington3650 The electrical properties of the conductors may impart some analogue change to the electrical properties of the voltage signal representing the audio frequencies, but I'd in my experience it would seem that at the distances and gauges we're talking about they would be so small as to be undiscernible. If there is a more noticeable change depending on cabling used, something else is going on.

I'm glad that you presented this topic quiet honestly. It is a topic that can be discussed forever. My question is when you mention pure copper Is it the OFC Copper or the 6N 99.9999% Copper ?

[@PearlAcoustics]

Hi Walter, thank you for your comment and kind words. In the case of our cables we looked more at the resistance per Km rather than the purity of the copper. I know that’s not how many HiFi cable manufactures see it but we stick to the standard international terms. I know it’s not the same thing but if you are interested the resistance of our cable it 0,78 ohms per Km. What we find important is how it sounds and in our case we just use it to form a ‘standard’ benchmark by which we can compare production with each other. And happen to like what we hear! Hoping this helps?

[@josuad6890]

Cables. Do they matter? Yes, of course they do.Without cable, your speaker are just an overpriced paperweight. With cables, they make good sound. Do "expensive" cables matter though? Fuck no. Get a cable from amazon basics and as long as you put those cables reasonably and put a reasonable load into them, they will just sound as good as the "expensive" ones. You say you hear a difference though? Good for you then. Data shows otherwise though, so it's 100% in your head or your previous cable is broken.

[@rjgarnett]

Exactly right. His explanation of the transmission of audio down the cable is weird. He says electrons clump together. How's that? They are negatively charged, they repel each other. Cables can make a difference. A high resistance, (long and thin) cable with a low impedance speaker will reduce the damping of the system which can change the low frequency response, but if the cable is less than the 10% of the combined resistance of the amplifier and speaker you won't tell the difference. Generally well designed amplifiers have output resistance of 10 to twenty times less than the nominal speaker impedance, so the speaker resistance is usually the dominant factor. Figure 8 cables usually have an inter conductor capacitance of 60 pF per meter so 5 meters will be 300pf. Assuming the amplifier output impedance at 20 kHz is less than 1 ohm the nominal cutoff frequency of the cable (-3dB) point will be 500 mega Hz ;way over the maximum audio range. Here is the best explanation of "current flow" in an electrical circuit.

[@robertm8518]

There are four main factors that affect speaker cables: The material of the conductor, Resistance, inductance, capacitance. minimize these as much as possible and you’ll have a great sounding cable. Multi strand OCC Copper sounds wonderful.

[@RobWhittlestone]

Thank you for another interesting video, Harley. My understanding of electron conduction is a bit more similar to Richard's below, however, so I'll have to forgive that part. To return to your water pipe analogy, voltage is more like water pressure and current is more like flow. Electrons are in a probability cloud in probable energy states like Bohr's model's 'shells'. As they are wave/particles with a negative charge they do repel each other. However the 'electron cloud' has a net drift from - to + terminal as the immediate potential difference pressurizes them to do so. The more electrons that arrive in parallel or within infinitesimal time intervals, the higher the perceived current. The actual physical speed or net drift of the electron cloud is surprisingly low - about one tenth of a millimeter per second - but of course, the propagation of pressure is near (50%-99%) the speed of light (what we call the speed of conduction). Here en.wikipedia.org/wiki/Speed_of_electricity is quite a nice article describing electron drift and conduction. In a speaker cable, however, we have alternating current, so it's a bit like watching people in a pool with a wave machine - one moment they are all going one way then as the wave reverses and they all go the other way. The people move a little bit but NOT at the speed of the wave. At the end of the day, electrons will not have drifted at all. So to refine our water pipe analogy - think of it as a transparent pipe containing smoke or fog. The higher the voltage the denser the fog; the higher the current, the more fog particles exit the pipe per second. If the hole at the end is small (high resistance), few particles will exIt per second. If the hole is big (low resistance) many fog particles will exit (high current). I hope this turned physics into something you can more easily picture - physics isn't always intuitive and rarely easy to visualize. This model is also flawed but is a little bit better, IMHO. Conducting cables are in fact transmission lines and have resistance, capacitance and inductance all of their own - all of those things that you wanted to leave out by having no crossover! Here en.wikipedia.org/wiki/Telegrapher%27s_equations is an excellent animated diagram illustrating exactly what I meant about electrons in a transmission line. As you can see, _everything_ has an influence and the old Quad phrase 'a piece of straight wire with gain' would even have resistance, inductance and capacitance of its own. Sometimes you just can't win! This is exactly where the experience of a designer is paramount, because it's all about making informed feats of balancing and matching one component to another. All the best from Switzerland, Rob

I think the main issue with this video is that you have tried to over explain stuff. What you should have said is this. "We have built the speakers with quality cabling from speakers to rear terminal and designed them to have an overall flat response across the listening sound frequency range" Then added. "No special high end speaker cables are required. Just good quality multi strand copper wire with adequate outer shielding. You can make these yourself or buy them in our store but they are nothing super special" This would have got the point across much better.

[@user-od9iz9cv1w]

Makes sense. What I did not hear is any comment on the relationship between the two conductors. IMHO it makes a difference if they are twisted vs running in parallel a few inches apart. I heard you mention that the hookup inside the box runs a couple inches apart. I had great success with simple diy interconnects using 24awe wires separated by 1/2 an inch. I thought why not the same with speaker cables. For no good reason I ran the two conductors 1" apart. They were good but had some sound characteristics I did not like. I changed to lots of twisted pairs and sound was different. An improvement to my ear. I was surprised you found no worries about the relationship between the two conductors.

[@PearlAcoustics]

I find twisting the conductors makes a big difference (improvement) when running over a longer distance. For example 4 cad 5 E cables platted together and then run per terminal. Works extremely well. But like all these things you need to try it to see. Best wishes

[@tjblues01]

@@PearlAcoustics Just a little note: CAT5 (and higher) are designed for frequencies 350MHz to around 1GHz. And that's why they are twisted so tightly. For an audio signal there is no need for that. An old fashion CAT3 (twisted pair telephone cable) will do just fine. The twist count in those cables is high enough to eliminate potential ingress from power grid (50 - 60Hz), crosstalk and the frequency response is more than enough for 20 to 25k Hz audio signal. The only thing is the current. So you have to put together few CAT cables to make large enough cross section area for caring the load. For ex. for a ~100W RMS amp - speaker system we need a speakers cable able to carry almost 4A of current. That be a wire similar to 10 AWG, which has cross section around 3.3mm^2. CAT cables are made of 22 to 26 AWG wires (0.4mm in diameter / 0.5mm^2). Hence we need 7 of those wires to make a 3.3mm^2 cross section. So basically we need 2 CAT5E cables (8 wires in each) to do the job 😉 best regards TJ

Cables are passive. They have no “sound”. If a cable sounds brighter than another it simply means it has less capacitance and is letting more of the signal through. Just get a good quality cable with low capacitance and be done with it. One can find these on the cheap. Who in the world would want to “equalize” with a cable. Considering we have about 5 seconds of audio memory to compare cables, without measurements it is a pointless exercise.

[@willemgoudappel5833]

I spoke with some one of the Dutch KEF distributor about witch cable to use with my KEF speakers.

Expensive cabels dont do anything to influence the sound, they are just a waste of money.

[@farcydebop]

The misconception about electricity is very well explained in the controversial Veritasium and Science Asylum channels. The Poynting vector equation shows energy is transmitted through the electric and magnetic field from the source, and not in the wires, resulting in the impedance problem with the first transatlantic communication cables, fried up as people thought increasing the voltage would solve noise distortion.

Most zipcord (lampwire) is marked in some way to make it easy to see which conductor is which. Make sure that the black side of each channel at the amp is connected to the black post of each speaker. That's really the only thing that matters.
