I used to travel full time as a consultant and always took my Cambridge Soundworks Model 12 portable stereo with me. Many times if it was powered on, without music playing, I could hear a local FM radio channel. I made a braided cable, and it never happened again.

I believe that if the cables were indeed that significant, it would have been easy to validate this hypothesis. the multiple inconclusive efforts to prove that this issue is indeed dramatic, prove the opposite - I hope to see a listening blind test instead of showing RF microvolts - all my life I am doing science and we have acceptable ways to prove or disprove an hypothesis. so lets do it

Thank you Danny for accepting this challenge. Regardless of the result, it will have been an educative experience for all.

Please do share the blind test video. I'm open to change my opinion. 👍🏻

I don't understand why people have such a hard time with this. Think about it for a second: For an FM antenna, it is totally possible to pick up RF and amplify it into audible audio. That means there IS an RF signal in the audible range that can be picked up by electronics, even when you don't WANT them to. A major reason the FCC exists is to regulate and control radio frequencies to prevent electronic feedback from crossing device domains in an unplanned / undesired fashion. So this is a real problem. Add in power lines and noisy AC power in dense residential areas is at 60hz. This is a problem in most urban areas. Anyone who has held a sensitive microphone near an unshielded computer will pick up EM noise in the audible range. Try it sometime, and you'll see it definitely exists. Anyone who has ever used a Nextell or wireless communication device near sensitive speakers or amplifiers will remember the buzzing pulses of the radio signal that impact your playback devices. I honestly believe the nay-sayers simply lack the necessary life experience to combine with their engineering knowledge to see how, even with the best shielding and filtering, you will never completely eliminate RF / EM interferance. It's a bi-product of using electricity for anything. Your best hope is to minimize it to the point where it is inaudible. That's why you use an appropriate level of filtering based on your scenario / needs.

It's been a month, and we're still waiting for that test.

Looking forward to this demonstration!

I did a blind listening test years ago by a famous mastering engineer who was very skeptical i could hear differences in interconnects and i got it right 10 out of 10 times. And this was also changing the direction of a certain cable.

A very informative video, love it! like most of your guidance videos, thank you

This is getting interesting, way to go Danny!

Waiting for a scrap of science. Still waiting!

If you so the speaker cable comparison. Then maybe make sure that they are measured or equal somehow (see below). Because if you plow down a lot of time and effort into this. Then it is not so useful if the measurements guys say "yes of course you hear a difference because the cables are of different lengths/resistance/gauge/capacitance/material. May I suggest that you take your nice speaker cable that is braided. Cut 4 equal lengths of them (when they are still braided). Un-braid two of them and make them straight. (The braid is the noise cancelation anyway) Now you have two pairs/sets of speaker wires that has the same length/gauge/resistance/material/dielectric. One pair braided and a pair unbraided. If you can make 10 of 10 with those two pairs of speaker wires. Then the measurements guys has can't argue against anything. Otherwise we will be in this blaming game in infinity 😅

OK, so unshielded, untwisted pairs of copper act as an antenna and detect high frequency RFI / REIN (Radio-electrical injection noise). Fine. At what magnitude? Several volts at several amps? No. Typical radio signal receiption levels - which isn't enough to power a fart. Are any of these frequencies replicable by an actual speaker driver unit? No. Even if they were, are they audible? No. These aren't the issues to focus on. What you need to focus on is the impedance introduced by a cable, and the impedance curve of the speaker across the audible frequency spectrum. E.g. my front speakers drop as low as 1.1 Ohms at certain points on the audible frequency spectrum despite being rated at "8 Ohms". Therefore, in order for transients to be handled accurately with all the attack, subtlety, and nuances, it's imperitave that my cables are impedance matched (e.g. not wildly different lengths to one another), and that my cables have an intrinsicly very low impediance, which is why I bi-amp my front speakers with four core 4MM (12AWG) cable, which has an imedance of 4.6 Ohm / KM (0.0014 Ohm / foot). That's all that's required to ensure that the speakers get exactly what your amp presents to them through all rapid-transients and low-impedance events. Thinner cable would introduce voltage sag under high current / low impedance loads and the impact of attack / subtleties would be lost. QED Performance Micro cable, for example, has an impedance of 29 Ohms / KM vs. Vandamme Black Tour Grade 4mm cable having said impedance of 4.6 Ohm / KM. This is the really important characteristic to look out for when choosing cable. If you're going to do a listening test, it needs to be a blind test, and there needs to be one or two instances throughout the test where your hired help tells you he has changed the cable, but in fact hasn't, to fully rule out any imagined changes or psychosomatic / placebo effect.

Here is a specific question. At what RF ambient field strength (in Volts per meter) do you start to need special cables? Obviously at zero you don’t need anything special, so how do you determine that? Have you measured rooms? Do you have any method to advise your flock who does and doesn’t need special treatment? Or do you just tell everyone to spend a bunch of money whether they need it or not? Also, the wires INSIDE you speakers have no special treatment...what do we do about that gigantic unacceptable exposure?

AudioTheoryReview - this is a good one :-) Keep up the good work!

13:20 - I am very excited to hear that you'll do a blind test video. I know that double blind gets a ton of promotion, but I think a good blind test is all anyone really needs. Just like the guys on the hyper-objective side say sometimes, as long as you're not getting feedback from the person or object that does the switching, that's all you really need. Double blind is just a way to make sure there are no hints. I get double blind, but I think it's really over hyped. The only need is to cut of peripheral communication from the tester and the subject. I do still think that if we can hear something and identify it, we should also be able to articulate what that is and quantify it. If we can quantify it, we can get an objective measurement with an inanimate object that is much much more sensitive than a human.

I'm half Italian and half German. My Earth looks like a square lasagna!

When flat Earthers actually do the science properly they prove themselves wrong, it's funny to watch.

I have a basic system and recently replaced my speakers with new ones. And as you should do was messing with the placement and trimmed the ends of the speaker cables and checked all the connections for tightness after prob 5-6 years since last check. The speaker binding posts have a different arrangement for the connecting bars between the lower an high freq sections, (they are internal). I set them to open and replaced them with jumper cables made from the same cable as my speaker cable. I noticed a difference, whilst messing around my wife had sat down and was on her phone not paying attention as I was back and forward a/b the jumper cables, she asked me what I had done as it sounded a better. I told her I was just listening to the lyrics of that particular song and continued to A/B between them playing the same track and she was distracted from her phone by the difference and told me when it was better sounding!! i.e.as soon as the jumpers were back in. I then played two other tracks with them in and then removed them and played the two tracks again, she asked me if I had done anything to the stereo as it was sounding better before!!! I then told her what I had been doing, she said I thought something was going on with her ears. either way for your self.

I hope to some day have speakers worth using those wires you had there!

Great observations and information. Thanks!

Take this for what it's worth. I had noise in my tweeter from a few inches away. Nothing crazy. Did Danny's point to point crossover upgrade. No more noise. I mean, zero. The hypex amp modules have a really low noise floor, and the quality of the components in the crossover upgrade removed a lot of useless metals from the signal path. I don't take this to the extreme and shell out tons of money, but I have had problems with noise, and have had to entirely redo my system. Things you wouldn't expect, like 12v trigger cables, can bring unwanted noise to your system. Personally, I'm a member of both forums, and have found great help on both forums. ASR helped me choose and build the right amp for me, and without audiocircles, I'd probably still be working on that damn crossover. Did my center. Can't wait to do the mains. Especially with mine in particular. Not sure what klipsch was thinking with a 10db dip in the midband

I will have to take your word on this, just like I take the word of the people who have proved the earth is round. Standing on the earth, I can’t see the curvature, but that doesn’t prove it is flat. Doing a listening test with the ringing I have in my ears that smears everything together as it is, will be fruitless. But, because I can’t (maybe can’t) hear a difference with cables doesn’t prove cables don’t make a difference. Looking forward to your up coming video and I will do cables, just because I am hearing such a huge improvement in sound quality with the X-MTMs I just finished and maybe cables might step that up a bit for someone else to hear, if not me... Thanks for your technical audiophile expertise.

Really looking forward to the blind test video...

Being a general flat earther, I have to say there is a reason for this flat earth concept. The reason is that in double blind testing (over 10,000 tests at least), no one has been able to correctly determine which cable was which. Now, that does NOT mean that if someone does a real test where levels are matched and the listener has no idea which cable is which, but they get the pick right one 75% of the time, then I will be the first to say that this person did it!. The problem is no one has been able to do it so far. So, if it happens, then it will be a HUGE, MAJOR advance in cable testing. Thousands of tests have been done with listeners who claimed they could EASILY tell the difference with NO PROBLEM at all. Then the "deer in the headlights" look after the tests as they found out they were not even doing as good as flipping a coin. The problem was they had never done a double blind test. They had done A/B tests with massive confirmation bias and convinced themselves they could EASILY tell. So, no one has been able to tell before but that doesn't mean it will never happen in the future. All that needs to happen is have the levels matched and then do not allow the listener to see the switcher or know which he is listening too. You can't have the switcher wander out from behind the curtain after he switches. He has to keep totally silent and non-visible. Also, no sounds of the switcher hefting a huge cable up for the switch. I can actually with a few visual or listening clues easily have someone be wrong 100% of the time. But anyone watching would not understand how I did it as they do not know what to look for. I suggest 20 switches and if anyone gets 14 right, that would really be that cats meow. Good Luck and I'm very interested in how this comes out for you.

Regarding your workmates listening with you, you described well the important task of learning to listen critically and learning what to listen for, this may account for a great deal of the false belief that cables don't effect the sound. We have to train our ears over a long period of time doing critical listening tests before we begin to hone in on what the differences are. And of course we must have a system that is sufficiently resolving in order to hear these differences. I will do a future video myself on how to do A-B listening tests and all the necessary criteria involved. You really are on top of this, and I am learning alot from you, wished I lived in TX and could come visit, keep up the great work.

It should be possible to use one cable, record the output, change the cables, record the output and use a bit of software to compare the two outputs. The old reverse the signal trick then switch the signal around and see what's different. Equipment can be calibrated, ears can't. I'm not trusting my ears, your ears or anyone elses ears. This "flat earthers" stuff is just condescending. People hear things in different ways, science knows this so to proclaim your ears are right and other people's are wrong is kind of anti-the-science of hearing as we know it. Yanny or Laurel was a prime example where roughly 50% heard one and the other half heard the other. That's, in part, down to the perfectly natural deterioration of our hearing as we age. I don't want to sound cheeky but you're a bit older, like me, and you're male. Both of these mean your hearing has deteriorated to a degree. Male's lose more higher frequencies than female's for any given age. It's no different to that other pair of sensory organs on your head - the eyes. Eyesight fades with age but the difference there is it can be corrected with lenses. Hearing cannot be corrected and we cannot get back the frequencies we've lost since our teenage years. en.wikipedia.org/wiki/Yanny_or_Laurel

Double blind testing is overkill. Single blind testing is adequate as long as the facilitator is unbiased.

raises an interesting question on how to measure soundstage so we have another metric to quantify speakers as well as all these part upgrades. BTW that is amir from audiosciencereview and sometimes he goes too far on the measurements but he does post these measurements online which are generally helpful.

It would be great to see the blind test with good mics.

There is a wire out there called Champlain. I would love to hear if it can used in a system considering its properties, even though it is a wire I use in a Motor Control Center. A 14 gauge wire is rated at 40 amps. It is silver coated copper with a silicone insulation

Its way easier to say its pointless to buy high end cable than to spend time and money on testing it yourself... If you dont believe better cable sounds better, maybe you dont deserve enjoying it

Respect for trying educate those who do not want to be educated. Every semi decent gear will be sensitive enough to translate benefits of addressing noise and interference issues by use of proper cables. But if someone has basic stereo with not yet addressed weak links might not hear the benefits. And here I think is the problem. To put is simply, people do not have good enough gear (or trained ears) to pick up benefits and build their opinion on that.

I hope more people will do listening test. It would be great if all channels could be a little more polite. By the end of this year I plan on making a great set of cables.

Borrow mics from Ron from NRD. He was able to pic up the sound differences when he came to your listening room for the speaker comparison.

I remember in high school, while listening to the then hi fi level system in the band room, we would occasionally be treated to the CB chatter from the trucks going by outside.

Measurements should back up what you hear, not the other way around. Countless times scientists have measured something that doesn't back up an experience, just to find years, decades later that they had to measure something else, or they've discovered new things and theories that can finally explain the experience. I don't know why it's so difficult for some people to accept that science isn't "done" at any time and it's always evolving...

Make sure the impedance of the two cables match. Everyone knows the lower impedance will play slightly louder and sound "better". You don't have to prove that. You can get Audtek 10 AWG for about 80 cents a foot. That should get you close. To check, you will have to play white noise through both cables and show matching SPL. Use a good SPL meter and document what the model was and what was the reading. It would be great to measure both of your cables for their properties also. I am sure Amir would measure them for free with his top of the line equipment and give you a fast turn around. This doesn't have to be adversarial. Danny, If you don't do a properly setup and documented test, you will walk away saying you proved your critics wrong and your critics will say you didn't prove anything and those of us in the peanut gallery will just throw up their hands in frustration.

In one of these cable videos there were 2 external links to some reference reading that Danny posted. What were the sites? I can't find them anymore. TIA

How often, if ever, do you upgrade your reference system. Do you continue to look for better cables, amps, preamp speakers etc? Thanks

I’m not really a part of the argument or I guess the better way to phrase it would be the discussion that you were having back-and-forth with the people in this forum because that’s not a group I’m part of… In fact I haven’t even seen the gentleman’s videos that you refer to; however I will stand up for this one fact because it is a concept with that I’m familiar with. When you transmit radio frequency waves into an antenna, you apply power to that point source and it can be interpreted as a voltage and an impedance and therefore you can determine the power. I you can look at the distance from that point source And use mathematics or measurement equipment to determine the field strength either by experimental means or calculation depending on what you’d like to do. I have very expensive test equipment that I can go out with and measure FM Field strength or for that matter AM field strength and its reasonably repeatable. The measurements that I am taking are actually doing exactly what you said, they are showing the voltage being induced from an antenna into an selective receiver on my end when I’m out in the field taking these measurements. And yes as you say they are quite small when you’re far from the source, a lot of times just on the level of microvolts… But if you’re close to the source, like an FM tower for a radio station they could be as much as 10 V depending on certain factors… Certainly if you were measuring AM field strength And you were near I 10 or even a 50 kW station… You could easily have 10 V of reception on an antenna that we’re just sitting there if it were the right length of wire. And .7 v as you know is more than easily audible (quite loud actually. ) So yes you can induce voltage across miles of gap using RF… That’s just in the laws of physics.

Amazes me all the negative comments. Just like flat earthers, nothing will convince them. Single blind, double even triple blind wont matter to them. Truth is it doesn’t make much cents to put hundred$ in cables on a $199 box store stereo, which is what most ppl listen to.

These videos make me wanna redo the speaker wires in my car.

I’m really interested in seeing this listening challenge video. When do you expect to have it up on your channel?

The double blind test would be easily accomplished... 1. Listener is blind. (Obviously) 2. The person interacting with the listener is not actually doing the switching expect to tell a third individual "A or B", not knowing which cable is labeled A/B. 3. The third individual would be the one physically switching the actual cables out. Out of sight of the other two participants. Then 1 & 2 could not impart biased based upon apriori positions or be accused of leading the listener in any fashion. The larger and more varied knowledge of audiophile listening techs of the sample size (number of listeners) the more reliable the results. Perhaps teaching someone who is not an audio person but is simply willing to allow you to teach them what to listen for, as you explained doing for your employees and seeing if they could get to a point of blindly picking out the difference between cables at a rate greater than that of chance?

It's a weird subject for sure. Anyone who suggests that there is a difference in cables gets berated by the anti-cable group. The "anti-cablers" do no testing themselves, and just parrot that there are no differences. I bought some high-end speaker cables before because I clearly heard a difference. (Tara Labs Air 1) The most vocal attacking person to me, was a guy (who after threatening me, I then found online), who lived with his parents, and was coming up on his one-year anniversary at his first job at Best Buy. His system consisted of the lowest end model of Def Tech tower that they made, and a basic receiver. My point is, that the people who are most vocal about cables not making a difference, usually have zero experience with real Hi-Fi. They don't own it, and they've likely never heard it. A high-resolution system is mandatory.

I think there are other factors of a cable and its connectors that make a bigger difference in the sound of cables. I am not an electrical engineer but it seems to me a cable is essentially a large capacitor. It has resistance, capacitance and resistance, varying any of these parameters will effect sound. There is also metallurgy. Silver sounds different than copper and down the line. Not only does different size conductors make a difference in sound so does how its configured or braided. The dielectric has a huge effect as well. So there are a number of aspects of cable design that effects sound quality.

Danny, All things equal, what makes most improvement -your PCs or SCs? And why?

blue jeans cable is enough

Audiophiles are super humans with the power of super hearing but like all super heroes, they have one weakness..their super hearing goes away the moment their vision is blocked

that braided cable you have is fantastic.i replaced all of my speaker cables for that stuff and what a difference.i had vandamme in before and that cable you have is much better. i got mine though from japan.

Does the guage actually matter? While working in car audio years ago, i had a person tell me that the guage from the amp to speaker made a difference. I did not try it back then and run the same guage ( 14 awg) through out my home theater system.

Actually wireless transmission of power has been around since the late 1800’s when Nicola Tesla invented the Tesla coil. Tesla could hold a lightbulb in his hand on the top of a mountain in Colorado and it would light up without any wires from a power source miles away. Also when I make Tesla bifilar coils to wirelessly transfer power through induction I use high grade copper speaker cable from Amazon! :)

I think that in order to hear such differences everything else in your system should very, very good - source, dac, amp, speakers. Even more importantly - your room should be acoustically treated (like the one in which Dany is doing this). In normal not treated living room, with moderate class electronics and speakers, which would be like 99% of people :) Even with very good system but in normal room, I don't think you will hear any kind of difference. I am not saying that the audiophile cables are snake oil, but they are very close to it :)

You may want to reach out to Ron as he has been struggling to make "good" recordings and no doubt has Learned a lot, and I'm sure can make some worthwhile suggestions. For yeah, making recordings that truly capture Sound-staging (and more) is no easy feat.

You have the heart of a teacher. Thanks Danny. Belden Cable manufactures all types of cables. They use different recipes for sensitive communications, video cables, etc. All cables are not just the same plain recipe which they would be if signal transfer was not compromised!

Please do this. And maybe incorporate more than 2 cables. Maybe 5...but at least 3. And switch 20 times random. I look forward to seeing it. And is it really worth the dif in price? It would be great to get the best wire for 100-200$ (6-10ft)... and compare this midrange set to high end

I may or may not agree with your methods involving cables, but I do admire and appreciate your diplomatic, and elegant way of addressing the subject related to the ones presented by the other 'guys.'

Double blind could be achieved with two switching boxes with relays or something. Either stick to manual switching and try to hide the cables some other way or make it computer controlled so you can add randomness

That power supplies all have filtering is based on how powersupplies actually works not really to filter incoming noise. That beeing said most soundgear uses a transformer that electrically seperates the incoming power to what goes into your amp, is then chopped up and filtered. So its quite questionable how much cld possibly make it inside an amp. But its hard to prove 100% that nothing makes it in, and possibly depends how noisy your electrical system is.

"Bless his heart..." Still one of the greatest family friendly "FU"s of all time. 🤣🤣🤣

Talking in circles is an art. Well done Leonardo.

Hell yeah Danny ! I have already gotten one of your trolls that subscribed to me channel , already catching heat over the NoRez lol from someone who never used NoRez lmao ! He might be a flat earther ! I will be honest with my expierence with NoRez video coming tommorrow thanks Danny keep up the great work ! Audio is about having fun !

These videos are really great and the flat earthers are clinically ignorant

Definition of listening test: How would you rate the sound of this (sales)person talking about the time he did a listening test? An audio engineer's intuition: Sure, I can use to camera's built-in stereo mic...

Double blind is indeed a catch phrase. Most who reference it have no idea what it is or how useless it is.

Please can you tell me if I were to bound 5 lengths of speaker cable together into one cable would it improve to sound quality?

Single Blind testing is good enough, for this purpose. The idea behind double blind is that you further reduce bias, by removing the bias of the person doing the A/B switching, as well as the listener. It has been found, that the person doing the switching could POSSIBLY influence the listener. But, I see where you're coming from; double blind is just not practical, here. Also, as fan of both youtube channels, I'm not sure you're giving Amir from Audio Science Review a totally fair shake. You should check out his credentials, he's not just some bum trying to operate an Audio Precision analyzer. Also not sure if you missed it, but in every video there is a section about the listening portion of the testing, where he gives his impressions. When it comes to the Audio Science Review forum, that is a different matter. There are all sorts of folks that post there, and they all have varying opinions and expertise (or lack there of). Some of those folks want to measure without listening. Sometimes, though, as we have seen with crossover design: if you can see a dip in the frequency response where two woofers don't play together, do you really need to listen to know it won't sound very good? That being said, measurements will not tell you how something sounds, it will just draw your attention to errors and design flaws. However I don't know anyone serious who claims the contrary, so that argument is a bit of a red herring. Specifically Amir, does not claim this. My own 2 cents: I have heard a difference when replacing standard zip cord, sloppily attached directly to the binding posts, with 6 9's copper, insulated with non ferro-magnetic spades, but I'm not sure if I was testing the cable per se or the connecters. The nicer cable was not really that expensive, however.

Can't say he's not consistent but I would say that cable comparison looks like comparing a Ferrari to a Toyota Tercel looking at those cables. I'd rather see you compare a Lexus ES350 to a Camry. And yes, hearing differences through KZfaq through our speakers is almost pointless because it doesn't work in general. I would never say using a semi high-quality cable is pointless it's just the $15,000 every three feet cable seems ridiculous!🤯

Hey Danny ,, you don’t have to prove nothing to me,, i have been a professional masking engineer for over 30 years ,,and I use your cable in my professional mastering set up,,and it does make a difference,,,... and as a result ,,my mixes are better... just let the people in the know enjoy ,, and the haters.. can stay in the dark..eat his flat...lol

I saw "Understanding Danny Richie" talking about Nirvana's song "Heart shaped box". In this video you also mention Nirvana and I guess the song "Heart shaped box". As I understand it, you hear three guitars, because I can hear two clearly one a bit to the left of the center a bit into the soundscape the other to the right behind the speaker with a little lower volume, where is the third guitar then. I also listen to "Heart-shaped box" on the Deluxe version (with 43 tracks) from Qobus (Original Steve Albini 1993 mix) track 19, the left guitar is more in the center and the other guitar a little to the right and a little further in, that sounds like what you are talking about. But you hear a third guitar Is this correct?

Any update?

Danny - Terry of the PursuitPerfectSystem channel ( /channel/UCrqva7JT_35j4zNcgan47bQ ) *has made some excellent high quality recordings that make signal and speaker cable differences audible* Somehow he manages to provide high res. audio on his KZfaq channel. It might be worthwhile asking him how he did it. Even I can hear the differences on a PC with a pair of budget Sennheiser headphones. Check this one out /watch?v=bVopaHeCtFs for example. Note Terry includes the hint *Put video in 4K for best sound quality* Referring to your comment about AudioScienceReview and RF on signal cables, I wrote Amir that he should INJECT RF into equipment (eg. a preamp, etc.) and measure what it does and LISTEN to it too. Transistors and op amps used in equipment operate up to several megaHertz - often even shortwave frequencies (30 MHz). Even if we can't hear it, it doesn't mean it's _not_ being amplified electronically. One theory says it may cause a device (or circuit) to be close to saturation at that frequency which has a knock-on detrimental effect on the audible frequencies. Unfortunately many people who believe only in measurements are not willing to believe that there is more to cable performance than can be measured. And they are also not willing to believe any differences they can hear unless backed up by repeatable double blind test results. All the best, Rob in Switzerland

Also I worked I a factory making industrial machinery & many times shielding caused more problems than it helped

I can't see what the problem is. If you buy the cables and they don't make a difference then send them back and Danny will refund your money. If they do make a difference and the difference is worth the money..... keep them. Its not rocket science.

Awesome vid, and kudos for doing this!!

Who's going to run this test? One of your buddies or employees? Gosh I wonder what the outcome will be?

In my experiences other than the speakers themselves the capacitors have the most impact on the sound of a speaker. However I've found that certain amps respond differently to capacitors. My class D amps seem not t like the more expensive film and foil capacitors. So...I wonder how much of a difference can audio cables make? And are they worth it? I once read a review on an expensive audio cable and the reviewer didn't like the change in sound.

Hey! Thanks for doing this. I do trust you"re going to do your best to be honest. Can you do me a favor? Please randomize your switching. Going from A to B in strict alternation can lead to a false distinction. Just use a phone app for rolling dice or generating random numbers. If it's even, use A, otherwise use B.

For the record, I purchased the drivers and built the Encore X-MTM cabinets designed by Danny but I don't use any speaker cables or power cables because I built amplifiers and active crossovers that sit on top of the speakers with very short wires heading directly to the drivers, and are powered by 48-volt batteries that are not connected to the AC mains when I use the system. So I save bundles of money and get better sound by avoiding potential problems rather than trying to tweak the system with dubious benefit. And I have the knowledge, tools, and time to measure and listen my way to audio bliss because I am now a retired audio and electronics engineer. As far as Danny trying to be a teacher, I think that it is a noble cause to undertake and I applaud him for the attempt. However unfortunately Danny makes no attempt to try to understand and reveal WHY and HOW he hears what he says he hears, which is what real science, real scientists, and real engineers always try to do. Saying that a whole cable industry exists is not evidence, proof, or science. It also is not science when someone does some measurements which they interpret to mean that there is not enough objective difference to make a subjective difference and for someone to claim that there IS an audible difference they are simply wrong. And leave it at that without making any attempt to replicate the conditions where people claim to hear obvious differences. Both conclusions suffer from INSUFFICIENT science and form the basis for ardent and zealous fans for both sides, neither one being sufficiently grounded in science to proclaim victory. Sadly I think that the struggle will continue probably forever mainly because of preconceived ideas and expenditures on fixes by the cable believers, and the inordinate cost of doing real scientific and statistically reliable double-blind testing that MAY help convince SOME of the cable naysayers that audible differences might actually exist under SOME conditions. But without attempting to uncover if, how, and why audible differences occur, there is only INSUFFICIENT SCIENCE going on. As Albert Einstein has been famously quoted as saying, "everything should be made as simple as possible, but no simpler." And his natural curiosity of why and how there were observable differences from Newtonian physics led to a new and refined view of the universe. That's REAL SCIENCE.

If u have a 80000 dollar system and use 12ga wire u might hear a difference but if u have a 5000 dollar system u won’t hear a difference if someone is spending 10000 or more for speaker cables then they need their head examined

One thing has surely been proven - that a good portion of Danny’s viewers are willing to shell out for fancy cables.

12tc made a very noticeable difference for the better. Pairing the correct cables to speakers from amplifier is a critical factor for sonic transfer. Thank you Danny.

What is that cheap 12 awg cable made of? Is it OFC? Or CCA? Tomorrow I will test my new cable. Coming from an 11 awg OFC silver coated to my new kimber 8pr. Was just finishing the termination with bananas. I will use REW to see, how the frequency response is behaving. Powered by Marantz and fresh installed Elac 249. lovely speakers. I am so curious, if there is even more to discover ... or if it is only placebo.

Is the blind listening test video up yet?

All my systems are mid-fi and cables matter. And you can't fix stupid. Best, D.

hahah ACTUAL flat earthers?? you're kidding me

Why do people think that if you can't measure it you can't hear it, that's an assumption I have a problem with. Wire has electrical properties, of course they make a difference. Good, bad, better, that's all subjective. I've compared two sets of audio interconnects, both 1 meter, 1 tara labs, 1 transparent, and you didn't need a blind test, it was that apparrent. I can understand if you have to keep switching back and forth but this was 1 switch. Can't say one was better but definately different. Now the law of diminishing returns really comes in to play with audio gear, big time!

Obviously the cable nay sayer forgot about the feedback loop on all amplifier outputs !! It's the same reason why computer monitors used to all have ferrite cores wrapped around the input cable !!!

I would want to see a listening challenge between your cable and an inexpensive 10 gauge cable from blue jeans or monoprice not a comparison between your cable and an undersized gauge of cable where you would expect a difference. That kind of listening "challenge" would reek of the deceptive demos that monster is famous for. I'd also want to see a listening challenge with your power cables.

👍🏼

Are the cables the reason you have that low level buzz in your speakers?

This has reached pretty low ebb. Honestly, everyone knows that AC mains can induce a hum in audio cables. And why no mention of balanced cables? This solution has existed for decades, is commonly available and is standard in professional (analogue) audio cabling. None of this makes GR Research look good, I'm afraid.

Keep it up Danny , great video again.

Your ears aren't high class measurement tools of some kind. They are about the worst sensors we have and gez even worst as we get older. If I enjoy the music, everything is fine. In second instance I am gonna rely on my dog....If he doesn't yell and run out of the room, the interfering sounds are probably within tolerances.

Hell yes. Thank you for agreeing to do this. I always suspected you knew something your dissenters don't, but so far you've only provided simulations and arguments from authority or popularity, and to trust you on that would've been unscientific.

But tell me, if the radio frequencies that a speaker cable picks up matters, wouldn't you hear those in the speaker when the stereo is turned of if it mattered? Why would they suddenly be a problem when the music is playing? The signal cable on the other hand is going in to the amplifier and is amplified, so there might be a theoretical problem. What is your argument against this?

I was wondering if instead of just using songs why not use recrdings of single musical instruments. If there is such a thing of course. I can imagine that the decay on a triangle, the cavity resonance on an upright base, or even the live-ness of speaking voice would better material to distinguished the difference between cables . I would love to hear the test as I'm on the fence too. More likely bec my gear and or ear not good enough. Just my 2 cents.

Actual flat-Earthers leading the charge for cancel culture! What an exciting time to be alive.

Fuses make a big difference too especially the real expensive ones. Like PT Barnum said there is a sucker born every minute. :D LOL
