Here's my experience: I participated in a cable test in a shop a couple of years ago that included the administrator actually announcing which interconnect cable was used as they changed... a totally UN-blind test! The cables being used varied in price from around 30 bucks to 2000 bucks for a one meter pair. Literally everyone could hear that the $2000 cable was dramatically superior!! BUT, at the end it was revealed that the cables were never actually changed. The $30 cable was in place for the entire test. ;) In addition to the above, I have participated in and administered blind testing of RCA interconnects on several occasions. In these tests no one ever consistently correlated/identified RCA interconnect cable changes/sound quality regardless of the type of music/equipment used. So, I have to admit that re exotic cables I'm pretty much in the "it's snake oil" camp! ;)

Yes, you are right. A lot of these cables cost a few Dollars to produce and are sold for US$1000s of Dollars with ridiculous claims. Of course you need snake oil arguments to make people pay with such insane margins. I've also gone through many professional blind tests being official qualified member and had to get my hearing tested by a professional audiologist every year. Yes, forget about power cables, short distance RCA cables, optical cables, and even speaker cables at short length, as long as they are of decent quality. Obviously cable length matters and I wouldn't use a thin cheap speaker cable if the length was 50 feet as it would cost on the damping factor and perhaps some loss of dBs. Getting the noise floor to a minimum doesn't cost expensive cables also. And this video is completely unprofessional. Come one, using some Pioneer tuner set to a given frequency of 105MHz The ENERGY of captured RF is so tiny that it wont affect any power amp with near 0 Ohms output impedance. NO, if he wanted to be credible he would use an actual setup and use an RF transmitter in the room and measure the amp output with some 1kHz (an other) sine wave if there was any effect of that RF signal causing any change. Nobody wants to do proper blind tests or proper measurements on this topic because they already know they will fail. If FM radio signal capturing was such a big issue, why do they not consider the topic in their internal speaker wiring and cross-over filters where the two wires are not in proximity and antenna effects can be much bigger?

All this test has done is prove how good or bad those cables work when used as an antenna. How they work as speaker cables with both ends terminated and voltage driving the speaker is an entirely different thing. You need blind testing under controlled conditions to see if people can actually hear a difference, and that's where things usually fall apart for cables making a difference.

This is why I don't trust GR-R. You demonstrate a speaker wire can act like an RF antenna (which I agree, it can and does), and THEN claim the induced noise affects "the sound" without connecting these wires between an amp and a speaker. Gary correctly points out THAT would the REAL test of whether the induced noise is "audible" or not.

I didn't get very far into this experiment before I had to ask, "Why don't you just test for cable effects by identical signals nulled at the ends of a sample? We engineers do this all the time when looking for very small signal differences due to inequality. The resulting difference is the contribution of the sample cable. Big difference = not so good cable. The standard used could be an agreed essentially lossless bit of conductor. Also, for the cognoscenti, we don't care a wit about what the sample can conduct; we care a lot about what it changes. Null testing is a thing.

Danny, the ability of a speaker wire to pickup electromagnetic energy is of no consequence to audio because neglecting other factors, the audio information riding on the RF carrier must be detected (demodulated) to recover the audio signal. The signal strength meter only shows the RF carrier level which cannot be heard unless there is something to detect the audio signal riding on the carrier, either a diode in the case of AM or a frequency discriminator in the case of FM, neither of which is part of an amplifier or speaker. To prove this, put the cables between an amplifier and speaker in the usual fashion and listen for noise without playing anything. If you can't hear and measure anything different with the different cables, there is no audible or measurable difference between the cables. The reason that the big cable showed less signal strength is because it has some additional capacitance and possibly also inductance which acts as a filter, but this is of no consequence in the application as I just stated. Also, while noise can be radiated or conducted, the potential for noise from the power wires being conducted to the speaker wires is nil, because of the filtering within the power supplies. If it was being conducted through the power supply, it would result in clearly measurable and potentially audible results depending on the amplitude of the noise at the amplifiers output, degrading the signal to noise measurement.

Misunderstandings are always caused by the inability of appreciating one another's point of view.

The peril of a clash is aggravated by a more or less predominant sense of combativeness, posed by every human being.

And you are also right that the terminating impedance will affect the voltage across the wire, but the tuner does terminate the cable with either 300 ohm or 75 ohm impedance depending on which antenna terminals Danny used. And also the extra capacitance and also possibly inductance in the 4th big cable is why the voltage is reduced. None of this matters however because the audio modulated on the FM carrier cannot be detected as there is no such mechanism in the amplifier or speaker. This was a faulty demonstration of any influence of RF energy affecting the sound of a speaker cable. The only way to demonstrate if there are any differences between speaker cables relative to their capacity to pickup RF/EMI is to use them in the usual fashion between the amplifier and speaker playing nothing and listen for anything different between the cables.

It's a completely relevant test. It demonstrates the effect of an increased noise floor, which can effect the perceived sound quality.

While it's interesting to note that the different cable geometries can result in measurable differences in RF signal capture (all the antenna engineers just said "well duh!"), the test rig did its measuring here with a circuit specifically designed to receive those signals at the modulation frequencies. Just because an unterminated wire pair can capture RF out of the test environment (act as an antenna) doesn't mean that the signal will have any significance when applied in the actual circuit use case. The voltages involved between an amplifier output and the detected RF signal is likely on the order of 3 or 4 orders of magnitude (or more), and that RF signal is orders of magnitude above the ears ability to hear. There may be secondary effects on the circuitry of a poorly designed amplifier, akin to oscillations outside the audible range loading the circuit devices and affecting their performance on audible signals. Different amplifier topologies will also react differently (e.g. class D amplifiers of necessity employ filters to remove aliasing that would also wipe out any of these rogue RF signals.) In the end, it comes down to how you define whether something "matters". Just connecting random copper lengths to an RF input is barely the start of a proper test rig. If the assertion is that this specifically should be applied to speaker wire, at a minimum you need to have both ends attached to the typical terminations (amplifier output stage and speaker input - likely crossover components but ultimately a transducer voice coil). Only then are any measurements realistic and potentially of concern.

@garyl5128

I was wondering the same thing - how an unterminated pair of wires work as an antenna is a completely different thing to being used to conduct voltages in a complete circuit to drive a speaker. These tests don't prove those cables make any difference to how the speakers will sound. The only way to know is for blind testing in controlled conditions. Floyd Toole has done plenty of research into how people rate speakers in controlled conditions, and when people can see a speaker they will give different results to when they can't. The same goes for cables.

@@dannyrichie9743 How does it effect the sound ? Please explain how it's even possible.

I'm not going to discount the possibility that speaker wire may make a difference in sound. I worked with one technician who said his ears were so fine tuned that he not only could tell the difference in audio cables, he could tell the direction the copper was drawn when the cable was made. Myself and the rest of the shop had all they could do to not laugh out loud. Most of my life though, I was employed in the computer or Information Technology field. I did work for awhile as a professional audio technician. I've also built my own amplifiers and speakers. I can't say with absolute certainty, I have heard the differences in proper speaker wiring, but the fact is I don't have the same test conditions, or the listening room as he has. You have done yourself somewhat of a disservice in this explanation. I don't want to be mean here or suggest you don't know your business. My point is this test isn't correct. Sure, an unshielded, unterminated pair of wires can pick up Radio frequencies. Even doing twists throughout the length of that black cable can slightly attenuate picking up high frequency magnetic waves. The comparison of microvolt signals to a standard 1 watt @ 1 meter (2.83 volt) speaker sensitivity test would show you the tiny 10 to 50 microvolt signal you picked up is thousands of times weaker. This translates to well below human hearing threshold for sensitivity. No doubt though, once you connect the speaker wire to an amplifier and the other end to an 8 or 4 ohm speaker, even that radio wouldn't be picked up. Going further into your presentation, yes line noise can affect the quality of sound from an amplifier. It not only gets picked up, it gets amplified. Do I doubt your word that the best speaker wire will improve quality? No & yes. From what you say and experience in your hearing test lab, you may be right. From this tuner test I would say, I would have to say your findings are suspect.

I totally agree with you about the general behavior a cable can have, acting as a filter or antenna. But as a engineer of electronics, I widely disagree with the testing setup you chose to demonstrate potential effects of loudspeaker cables on your stereo: For your video, you connect the cables to the antenna input of a tuner. Off course, the tuner input stages, used to deal with those very low antenna voltages will pick up the noise as any antenna signal. And, yes, twisted or even shielded cables will result in lower input signal to get amplified by those FM input stages. But in real life, we do connect those cables into the output of an amplifier, from there going into the speaker. Both power amp-out and speaker in-are low resistance (4-16 Ohm for the speaker, and most often a fraction of this on the amp output). This will shortcut the high frequencies with such antenna-like low voltages completely if the amp is built properly with a grounded housing. My conclusion and experience: if anny noise from the air creates noise in your system fed-in from the speakercables, something is wrong with the amp - and, yes, it can happen with cheap gear or a damage in the electronics. A totally different thing, not adressed by you here, is that twisted cable designs can positively impact cable capacity and inductivity, resulting in finer details getting to the speakers more accurately. But also here, I doubt the extreme promises of the audio accessory industry and the dealers, lurking for some extra revenues. And what nobody tells us is the fact that complicated twisting makes the effective cable lengt go up by a factor, resuling in higher Ohms between amp and cable - not a good thing at all! Looking at the speaker cables at large concerts (huge speaker arrays and power amps), they mostly use non-twisted but very large diameter cables, made from good copper, connected with the professional Speakon plugs that provide extremely good connection with the amp and the speaker terminals. What makes those cables a bit more expensive than the "Wallmart telephone string" is the shere diameter and the highly ruggedized and flexible and robust outer hull. Some years ago I spoke whith a nice sales guy of a famous German cable company, seeking for some advice. In a nutshell, he told me "Yes, we also produce some of those multiply twisted loudspeaker cables just because we have the machinery for it. We sell those cores to different companies that finalize the cables, attach some golden bananas, and sell it for incredible prices to all those idiots in the market that would better spend their money to improve their room acoustics."

Exactly.. All well said..

If you can repeat the same with a 8 ohm resistor connected to the other end of the cable, and show the same results, that would be amazing....Or you connect an open cable to a speaker and you can hear something from the speaker. Show me.

I remember when Hi Fi choice did a blind listening test on 20 cables using a group of their readers Cables from £20 to £1000 a metre BUT with a piece of household solid core "twin and earth" thrown in as a bit of a joke When all the results were in and aggregated (no small task, I think they had 6 listeners) The twin and earth came in......third. A lot of egg on a lot of faces, and they've not run that type of test in the 20 years since. There's a big difference between the bell wire interconnects and speaker wire often supplied and thicker, screened, oxygen free stuff, there's even an audible difference (very slight warmth in multi) between solid core and multi strand. But that's as far as it goes in terms of sound quality in my experience. Put the money into better speakers, it'll make a far more profound difference

Yep. I used to install audio systems in cinema auditoriums. Big room, very long cable runs, big power. We field tested a whole bunch of different cable. Our conclusions? Unless you're dealing with a REALLY long run of cable (like, over 50 metres) then regular old decent quality 240 volt 2-core flex is just fine. If it's good enough to carry 240 volts at 10 amps then it's well good enough to use as speaker cable. It costs about $1.50 a metre at any hardware store. Plus, as many others have pointed out, the bottle-necks in most systems are: a) how the signal is transferred from the output transistors to the speaker terminals inside the amplifier b) how the signal is transferred from the terminals to the crossover and/or drivers inside the speaker cabinet. Most home stereo amps use either micron thickness tracks on the board or very small gauge cable to carry the signal from the output transistors. Some better quality amps may use solid copper busbars, but even in the biggest power units these aren't more than 3mm wide and are totally un-shielded. Most speakers use fairly small gauge cable to carry the signal from the terminals to the crossover network, which is itself a bottleneck as it's a circuit with tiny connectors and micron thickness copper tracks. Even if you're wiring directly to the drivers the size of the connecting lug is the determining factor. Using any cable larger than that lug is superfluous to requirements. In all these scenarios the use of fancy expensive speaker cable is utterly pointless. Yes, I've got a decent system at home. Bi-amped, big power amps, the whole bit. What am I using as speaker cable? 240 volt 2-core flex. Cost about 10 bucks. It sounds fantastic. Spend your money on better components - don't waste it on ridiculous overpriced ancillary garbage. That $250 you spent on cables could have gone toward a better cartridge for your turntable - and that would be a difference you can actually hear. Anyone who says they can hear a difference with their fancy expensive cable is justifying the reason they wasted their money, nothing more.

I think what all this boils down to is CABLE ARCHITECTURE. If you took notice Danny used a variety of cable from straight wired zip chord to increasingly complicated braided multi-stranded, multi-cored wires. What happens as you increase the complexity of the cable is a reduced noise floor, because the braids act as a faraday cage on the neutral, which is where most of the noise tends to be. In my own recent experiments making RCA, and speaker cables I have found a profound difference when the signal wires are shielded by the neutral, that is, wound as close as possible to 90 degrees around the signal wires. Results were a much reduced noise floor, cleaner, clearer, sound, more detail and nuance. For all the naysayers I suggest you actually build your own cables before you criticize Danny's findings. You don't need to spend a lot of money to get stellar results if you DIY, either. I have been utilizing Steeve Reeve's designs, in particular his RCA cabes, and his speaker cables with fantastic results. He explains the engineering behind the design in easy to understand terms.

If you live in a power plant it could.... In most of the regular homes an extra shielding does nothing, assuming that you prepped and connected your audio cables properly. Induction on both wires is in opposite phase hence it cancel each other.

I'm curious about "low mass" connectors making such an improvement, but the full length tin plated copper leads on all the cross over components are twisted together in a mess and gobs of tin/lead solder are applied. Seems kind of contradictory.

Isn't the FM signal neglectable small compared to the speaker signal?

@dannyrichie @gr-research what are your thoughts on power conditioners (i.e. Furman) that filter out noise?

The discussion at the end regarding shielding, you were talking more about noise from your local energy supplier rather than picking them up from the 'airwaves'. Are they actually analogous as you implied? I.E. Will the shielded cables actually not reject radio noise, and will the braided cable actually filter power supply noise?

I would be all about an even deeper dive. I am working on my ascent to decent cables. I just need to learn how to get what is good, not what is expensive, because I am poor. Ha ha. I learned a bit about this noise-floor issue. I use my computer as a source. I had gotten a high quality USB ethernet, then through 25 feet of Cat 5, then through yet another USB. Not only did it work, it immediately sounded better. I could hear the lack of noise, though I hadn't noticed the noise before. It was almost like a loudness filter, because I could listen at much lower levels and still hear definition. I don't want it to be this way, but it just is, and I want BETTER. . . I'm an avid DIY man, and would like to create my own cables, if I can do it, but how to test.

While it may not prove they will sound tonally different, twisted pair will reduce noise and is a proven fact. You cannot send 10Gb of even 1Gb of data for 100 meters on Cat3. While the Cat6 and higher use the same copper, it is the amount of twist they use and the termination which allows higher bandwidth and reduce rf over the 100 meters. While there are some shielded network cables, the majority are unshielded and use twist (or you can use braiding) to reduce interference. IEEE creates these standards and can be verified on IEEE.org.

​@@mickyd3 This is nonsense. Cat 3 cables don't encounter crosstalk issues until 16,000,000hz. Audio stops at 20,000hz. 20,000 vs. 16,000,000. Cat 6 cables don't encounter crosstalk issues until 250,000,000hz. Cat6a cables are clean to 500,000,000hz. So each of these cables, which are differentiated by their construction, all have different bandwidths they can pass without any alteration or issue. We can measure this. We don't take a ScanSpeak 18W and exclude it from our system due to it's poor response at 15,000hz. We consider the application of the driver and understand the frequencies it will pass and we are uninterested in it's performance at 15khz because that signal will be filtered out by our crossover network or DSP. We also don't choose our drivers based just on one response, we look at THD, impedance, and spl all over frequency as well as other things. So then why should we take cables meant to transmit amplified analog signals to drivers and consider ONLY their performance 15,980,000hz outside of their passband. Or in the case of Danny's test the lowest FM radio frequencies are 88,000,000hz... so that's 87,980,000hz outside of the passband of the cables.

Makes sebse, but where do you source your cables? I followed the Cast copper thread to the Japanese metalurgist papers he wrote while at the university of Toronto and then found a company in Canada that uses cast copper for their cables. In the days of a pandemic I have no idea where one could listen to these cables, do you have any suggestions?

I still want to go into the listening room.

Record 2 different cables, then sum the 2 signals out of phase. This should show any differences.

So what gauge Wire does a good speaker have to the speakers and cross overs internally? i used to have that Tuner with an Integrated Amp in the late 70's

Here's a few things experience has taught me over thr years. 1) people usually underestimate the importance of the connectors/plugs. You can have the best quality RCA cable and ruin it all with RCA plugs that introduce connection resistance, especially on the mass ring. So don't fall for fancy cable talk unless you take a look at the connection itself. 2) cable capacitance has a huge impact on a turntable's or rather cartridges' performance through cable capacitance when you run an MM cartridge. 3) exotic devices with stranger electrical input/output parameters will react to cables with different conducting parameters like inductivity or capacitance. Know your devices before you buy a connection. 4) less is more. Choose a cable that is as short as you can get away with. Also, choose a cable that can be arranged without putting additional strain on device sockets. Don't try to forcefully bend a very stiff cable into a radius it isn't designed to be arranged in. 5) don't cross signal cables close over power cables. You don't want to introduce some strange AC hum into your signal paths through induction.

This test only shows how much RF noise is picked up by different cable geometries, nothing more, nothing less... This test doesn't show anything about how a cable in and of itself affects the sound quality of the music signal flowing through it, this test ONLY shows how much different types of cables can pick up additional RF noise. While this IS one relatively minor aspect to consider in finding a good cable, there are many other, even more important cable "qualities" to consider first. One question to ask here though, is if the braided cables act as filters of high frequencies, then (theoretically at least), wouldn't those same cables slightly attenuate the subtle details of the highs in the music signal passed through them, at least of the musical harmonics above 20KHz or so?... The frequency harmonics of music from 20KHz to at least 40 or maybe 50KHz or so still add some life, depth, and realism to the overall sound and tone of certain musical instruments for example, and that has been talked about for decades in the hi-fi audio industry, so you wouldn't really want a cable that filters out any of the high frequencies would you??... Any thoughts on that?

My concern with the measurement only crowd is regarding if the right measurement(s) are used or even exist.

Yeah, it's usually the engineer types who believe in measurements by machines and others who simply believe that they have noticed differences by changing various cables in their systems. Personally, I think that various aspects of wiring/cable do have an impact on ultimate sound quality coming out of a speaker system. It's really just a question of how much of a difference and if that difference is audible. The other problem is the virtually infinite possible combinations of cable/equipment that can have unique interactions. Synergy between equipment like amplifier and speaker is one such example that I have personally experienced in very clear ways.

Thank you so much for this video. I recently viewed it and realised I had spent far too much money on braided, unscreened power cables. Because I only heard marginal improvement over bog-standard cables, I mistakenly believed there was little point bothering with 'better' cables. After viewing your video, I purchased two very cheap (£23 each) screened power cables which transformed my Echo Studio speaker from just about OK to almost hi-fi. I have since replaced all my power cables and it's transformed the music. I also replaced my speaker cables with CAT5. What a difference that made! This has been the cheapest major upgrade to my system ever. Please keep sharing your knowledge and experience.

As a graduate from EE, I have to say the conclusion of this experiment is highly unjustifiable. Yes cheap cables pick up interference but does it matter? That interference can be measured by instrument doesn't mean it can be heard by human ears. First, if the frequency of the interference is outside the spectrum perceivable to human ears, it doesn't matter at all. For example, if the interference frequency is 100KHz, human ears cannot hear it at all. Second even if the frequency of the interference is within the spectrum perceivable to humans, is the strength of the signal strong enough to be perceived by human ears? If the signal / interference ratio is higher than 85-100 dB, the interference can be ignored totally.

The noise is just simply too weak to be applied to speakers for people to hear.

I totally buy the way that the noise is no longer allowed in the cable. Basing my assumption that these cables are set up between the amplifier and speaker, I am curious how much the noise actually affects the sound - is there a way to show a percent of the amplified signal that the unfiltered noise becomes? Put another way, I can't hear a cd player to amplifier signal, the signal traverses to the amp and goes from lets say a level of 1 to a level of 100. That signal at 100 is then passed to the speakers. Does the unfiltered noise incoming through cables create an audible effect, given it is not amplified? And can you help me understand how this can be applied to digital signals between components? My understanding is that a 0 or 1 is a 0 or 1 - though may have some "rounded corners" on the signal. Insofar a 1 is still a 1 when the rounded corners are taken into affect, why would it matter? Thanks!

The test did show how different wire configurations change radio reception. The next test needs to demonstrate how this becomes audible. Common low frequency radio bottoms out at 30 kHz, which is above human audibility. Further, that is 30kHz of electromagnetic radiation, not sound. The human ear cant hear electromagnetics period, so what component acts like a receiver that translates the data into an audio signal? This isn't flat earth criticism. When we wanted to SEE that the earth was round, we took a picture that we can see . . . Radio waves are essentially light outside the visible spectrum, so when we are supposed to hear something, what good is a picture?

I retired from electronics training/education. And I retired from audio voodoo long ago. I still build low power (under 40 Watts) tube amps using only NOS USA made tubes for myself and a few friends. Most popular are the 18 watt P-P 6BQ5/El84 tube amps. Response is tested and all will meet these frequency response parameters 30-24K + or - 2 dB. Getting down to 20 Hz just was not worth the additional costs in output transformers. I used regulated DC for filaments and the HV power supply is remote using coax to feed the amps. Spent many years modding Dynaco's. This video reminds me of a Doctor that spent a fortune on the Silver wires during the Silver wire fiasco. Had me install them on a system I put together for him and installed driving a pair of my speakers. A week later he was raving to me on the improvements several thousand dollars bought. I told him to look at the back of the speakers where he found the speakers were still wired to the copper I originally installed and the silver wire was still in the package. I ask if he understood the placebo effect and he laughed and returned the unused Silver wire and sent me a check for his "education" and saving him thousands of dollars.

do you know that you can calculate cable inductance? do you know that this value will be negligible compared to amplitude of the signal generated by the amplifier? even if it is such a problem that it occurs, it is eliminated by shielding the cable or in the case of stage equipment using differential transmission

What does it measures if the speaker is connected ? Wouldn't the voice coils shunt out any Mega Hz signal ?

The tiny current created over lets 0.2 ohm resistance in transistors gives a miniscule voltage. In the radio circuit the resistance would be in the thousands of ohm so using Ohm's law, voltage = current x resistance(high value here from the high resistive impedance radio circuit) would give some useful voltage affecting the VU meter in this example. There is no measurable voltage beeing able to build up since its shorted out by the low impedance of the speaker circuit..

Hey Buddy can you make those wires into interconnects I am getting some radio interference between my phono and my preamp

I have done many tests working as a sound engineer, both live and in studio, attempting some level of blind testing. @manthropology - there is definitely a 'it sounds better because I just spent $100 on 8ft of cable' effect- which is a well known part of psycho-acoustics. Ultimately the speaker cable's practical measure is its efficiency to tranfer power over a given length and the capacitance over that length. The thinner and longer the cable, the greater the voltage drop- basically a resistor- that steals power from the speaker. And running two conductors beside each other will always result in some capacitive effect, that shunts high frequency to ground. Zip cord is of course crap because the thin wire over long length acts as a resistor (voltage drop) reducing power transfer to the speaker and can lose some HF due to capacitance. So heavy gauge cable, results in higher capacitance because with so much copper surface radiating EMF, resulting in HF loss and lower resolution in subtle trailing reverb. Braided cables provide high power transfer with many combined smaller conductors, while reducing parallel surface area by braiding together. The RF is irrelevant in a closed, relatively high (by magnitudes) voltage circuit. In large scale live sound, thick cable HF loss is secondary once system equalization comes into effect. But multiconductor braided cable (in-studio tests) definitely gives the best of both worlds, with higher power transfer and lower capacitance, which improves high-end response and reduces HF smearing caused by time domain shifts - thus clearer reverb trails. With line or level, RF is one of other significant factors, but there's a whole other level of chicanery going on in this area too (Monster cable among many). However have worked with braided quad conductor (Canaire Star Quad) cable that was well worth the premium. I have never used a 24 strand, which may be worthwhile for very high power levels, but a commercial studio (short of very high-end facility) would defer to the practicalities of diminishing returns.

What you are missing here is that any decent receiver will produce a good audio signal with RF input of a few microvolts, or put another way, a few nanowatts. A few nanowatts of noise on a speaker cable cannot possibly be heard against the desired signal which will be at least 9 orders of magnitude greater than this noise. Zip cord is all anyone needs.

I would love it if you could do a video on how to make these cables.
