Listening on phone speaker at arms length and difference is very obvious. Great video.

Right now I'm a big fan of Blue Jean Cables because they seem to be well built for the price and share a lot of specs (their interconnects the LC-1 has super low capacitance). Maybe one day I'll try even more expensive and see if I can tell a difference but I feel better using something above the cheap amazon/monoprice cables.

In this case I knew there will be a difference before listening and there definitely was. What most people don't understand about cables is they don't add anything, they just take. The cheap cable has poor shielding if any thus the high noise (well, they can add in the case of noise), also has a higher resistance thus the weak lows, a poor cable can act a bit like a low pass filter or high pass filter so it will either make the sound warmer or bright *but that's by removing frequencies from the signal not adding to it, that what people need to understand!* You don't need to spend $200 to get good shielding and low resistance, as iiWi said the difference between that $10 and the expensive cables will be very hard to hear. Like anything in life avoid the cheap crap and don't go insane with diminishing returns and you'll be just fine.

Initially I thought A sounded better and more open, and the first switch to B made it sound "squashed". But after more listening I realized that B was much more "full bodied", and the "openness" I thought I was hearing with A was just a result of the brightness and the lack of bass. Personally I think you only need to spend around £30 to get properly good cables. You just need something well made and properly shielded.

I like the sound of cable A

A sounds better to my ears without knowing which is which. With cable B, the guitar is a mess and vocals less clear. Also there is more hiss noise with cable B.

This was the first example of a cable making a difference. People saying cable "A" sounds better. I think they are only listening to the bass volume. Cable "B" opens up, like it is a completely different stereo all together. It became more spacious. I even heard something with the acoustic guitar in the right (Possibly Left, Think I had my headphones on backwards) in the first track change. It jumped out at me. Also it gave a very holographic soundstage in which cable "A" was very box-ie sounding. Cable "B" is where its at.

Great video - objective without any obvious biases.... more video's like this are needed!

Thank you so much for telling us your truth.💯 I'm a rookie to all of this. I'm just putting together a 5.1 surround home theater. I got myself 2 SMSL dacs and some nice new bookshelf speakers. Nothing crazy. But after watching this, I'm going to save some more pennies 😅 and get some good cables👍🏼 🇨🇦❤️🇯🇲👊🏽

It just remind me my first cable change when started my journey with hi-fi system and that was Yamaha Piano Craft 20 years ago. And now thanks to your video I could hear exactly the same difference. And I have to tell you what. I am so glad you done it this way as I think nobody done it before. You can hear black and white the difference. Ofcourse set B sounded waaaaay better. Set A sounded completely flat like vintage radio. Set B sounded 3 dimensional even via YT. But couldn't really pick up any specific sharpness of the cheap cables on my headphones due to compressed signal on YT perhaps. BRAVO and thank you for this video. Amazing job. 👍🙃

Wow! Just Wow! Thank you so much for doing that my friend! I have already watched like 3 or 4 videos of yours (basically your cheap dacs reviews) but for this video alone,i just hit the subscribe button.For me,that was super informative! I knew speaker cables can make a huge difference,but interconnects? Wow! Being able to hear that via youtube...that much of a difference just from interconnects i did not expect! That was eye opening for me! Thank you so much!

Huge difference. Blindly, cable A sounded better. It sounded more forward, transparent and clearer. B sounded like somebody increased the mid tones and didn’t sound right to me at all. Much more hiss noise level. Interestingly, the moment you mention B was the more expensive one, mentally I try to rejustify everything, trying to change my perspective that B was actually better than A. I am pretty sure most people here did the exact same thing. Don’t kid ourselves guys!

Just me, but I heard a considerable difference. The beauty is you can create what sounds good to you... Who's to say what sounds good in your scull ?..... Have fun experimenting with sound. What a great gift of life !!!!

I could easily here a difference just on my phone. Cable B did sound better to me. Nice video, keep them coming.

Clear difference absolutely. Cable B sounded more "full bodied" I'd say and cable A sounds sort of bright. Amazing video mate, well done !

People had been complaining about a hissing type feedback noise from the Eris E7 studio monitors. I went ahead and bought a pair anyway. When I ordered, I ordered a pair of 2 meter decent quality XLR connectors, silver/copper, shielded. I also ordered a high quality shielded USB connector to go from my PC to my SMSL SU-9n DAC. The first thing I did upon setting up on my PC Desk was listen for any type of noise emissions from my Monitors. They are Dead Quiet at idle. I also have a dedicated AC power box with backup that also filters the current from the wall. I was careful upon laying out my cabling to have as little crossover interference as possible. So yeah Your Fiend was quick to blame the DAC and I am guessing that many of those not happy with the Eris E7s were suffering from some kind of interference. I am so very satisfied with the results. I look to your channel because of the honesty that you project and the concise explanations of what ever is the topic. Thanks for That.

I forgot to add, cables are “tuning” tools to tweak the sound of your gear!. Totally agree with your observations!

To me, cable A sounded more forward and full in its presentation with a narrower soundstage while cable B sounded recessed with a wider soundstage. I tended to like cable A in the first track and cable B on the second track. Even after hearing which one was which, it didn’t really change my opinion or my preference. I’m sure the harshness you mentioned on cable A was more apparent in person but it wasn’t audible in this demo once it reached my end.

Very well done. Very simple experiment and pretty darn obvious. I will be upgrading my cheap generic cables to mid grade ones for all my setups. Totally agree with your comment about investment into good quality gear. 12:52 . Also agree with measurements comment at 13:36. It’s OK to believe our ears even if we can’t confirm with the current measurements. Laughed at “ for gods sake! “. Nice job overall.

Killer video ...short and sweet and to the point...the difference was beyond what I anticipated...cheers

The cheap ones sounded better, but I guess the point you tried to make is that there is a noticeable difference in audio between the two cables. Will have to sit in your sweet spot to really hear which is better. Cool experiment.

You're a musician as am I .. Easy for us to hear difference .. but in this extreme example the proof is an undeniable FACT .. well done Bravo amico ..

I agree with you iiWi Reviews. I listened to the samples using a pair of headphones (Beyerdynamic DT770 Pro). I did not know which cable was A or B, before listening. Clearly , the more expensive cable pair (B) sounded better. Wider dynamics in the base and in general more details.

I'm annoyed to admit that there's a BIG difference, and even more annoyed to admit I prefer the expensive cable B 😆

Regardless of cheap or expensive. This demo clearly shows cables making an audible difference.

Super video, cable A was easy to spot as the cheaper one. I always wondered exactly how much cables actually can do. What I learned, which is the really big challenge, is how each component in a system can affect the sound quality/character. This was just another evident display of just that. You really should have far more subscribers, your reviews are ace.

Thankyou for taking the time to do a good balanced demo.

I tried many cables under £40. Audioquest, QED profile and pro, Amazon basics, Oelbachs silver ,Fisual . Mogami 2534 Quad cables worked the best for me. Apparently used by the pro music and film industry. Beware - I have realised cables need at least 50 hour burn in. Mogami recommends 75 hours plus for best results. At first I was disappointed, after burn in, I was happy. I was using for Pro- ject D amps.

Even through my crappy PC speakers I thought B sounded better. Well done mate, but no doubt it wont stop the naysayers

Thanks for taking the time to demo this and give us some real differences to think about. I'm neutral on cables being new to hifi but I did go for mid range price audioquest just because my shop had it and I didn't feel like connecting 5k worth of gear with cheap connectors and zip wire from home depot

Wow, you are killing with your reviews. Your analysis lends a gravitas to your insights that is trustworthy.

There is a really tiny difference but does not justify the 200$ investment. One of the sound is tiny tiny tiny tiny bit "thicker" or "richer". May be is the shielding of radio frequency in the air wave, or close proximity to other EMF emitting equipment. A 20-30$ cable does all of the necessary shielding within the hearing range of human. Good job in presenting this topic, keep it up.

Awesome demo. I was blown away by the stark difference. I'd love to more videos like this, I'm super curious about digital cables like USB or HDMI. There's so many debates online (like anything) over using $200+ USB cables to connect DACs. I personally feel like it can't be any better than a $20 cable, but oddly - I'd love to be wrong.

Cable A = More noise, lighter, less body, not hollow but definitely less impactful Cable B = Warmer, fuller and more rounded (Winner)

Without knowing what is "A" and what is "B", my ears prefer Cable A.

Cable A sounds closed in spatially, slightly blurry, and a bit shrill. Cable B sounds richer, more open in vocals, ambience, and instrumental detail. I listened via a Meridian Explorer 2 DAC, and a custom 6DJ8 tube pre-amplifier driving a transformer coupled headphone interface into Drop HE-X4 headphones. Quite a revealing comparison :)

Good demo, i use atlas interconnect equator RCA, and they sound very good with my amp + Bluesound node 2 i + smsl su9. The soundstage is fantastic. I also used atlas hyper cable interconnnect...but they were too warm for me. You're right .... interconnects makes différences !

Thanks! I listen to a lot of ‘reviews’ and this is straight forward and really useful!

I changed my cables (the ones provided with the DAC/speakers), which was a considerable improvement. Another thing that helps: keep the audio cables far from the power cables. No difference was observed when I used a cheaper DAC.

Another very helpful video for all of us to consider!

Audio cable is like wine. Most people will be happy with $5 bottle until they get the chance to taste $500 bottle. Even then, someone may still stick with the $5 bottle for one reason or other. But I am certain that the wine lover will be much more likely to find his/her favorite bottle in the $500 aisle than the $5 aisle. The $64k question is whether it is worth $495 more...

The difference is huge A sounds muddy, is compressed with narrow stage distortions phase shifting and resonances with Cable B the scene is huge (in comparison) with better dynamics better frequency response and details closer to original recording even through KZfaq, very impressive! As a sound engineer and audiophile i hate compression and limiting so I can very easily spot the (hugh) differences with my "calibrated" Sennheiser HD600, AKG k271 studio with my "calibrated" monitor speakers Yamaha HS7, Focal Solo 6 be and in my Livingroom with my HiVi Swans D2.1 DIY speakers also calibrated. I keep writing calibrated because this is the most important thing, first to have the right sound and then to judge if something if something is good or bad! So calibrated the uneven AKG sound almost like the most linear Senheisser and the Yamaha HS7 like a focal! There is some difference in terms of distortion and dynamic compression but this happens in high levels. Despite the results this doesn't mean that the cable B is "the cable" simply the cable A like i say often is (without cable) only a plastic shell with everything but the copper inside like all chip cables from at least 20 years, they use less and less metal so they causing huge distortions and squeezing everything. So don't use garbage it's a shame, if you have a descent system and if you don't here the difference something is very wrong with your system! If you you like the cable A you like garbage or something is very wrong with your ears or your system! My decision to this cable test is based more to dynamics and stereo imaging since is a representation of a hole system + room + recorder not based on spectral balancing. As a recording the microphone and the room + speakers alter the sound balancing so what remains to be judge are the dynamics and the 3D imaging. As a rule the cheap cables tend to sound dull and monodimentional with boomy and slow rolled off frequencies, the good copper cable sound balanced, natural, dynamic with fast bass notes. Silver cables tend to sound bright and don't recommended for every system and finally single core cables sound very - very transparent but in expense of 'low body' to some systems. The dielectrics and the shielding equally transforming the cables and there is not an easy formula for that. There is also not exact formula or recipe for price performance to the cables "they are many snake oil cables also" but the fact is that the pricier cable is better than cheaper but this doesn't mean that a pure gold cable sounds the best.

Hello. I couldn't hear a difference but my ears have seen better day's. To many concerts and nightclubs. However I do use the minimal upgraded cables and they definitely make a difference. I also wanted to tell you that I really enjoy your channel and you're a super nice person. Having said that, your demeanor comes off as you being very honest and trustworthy. I wish I had one third of your knoledge but I'm working on it. Thank you very much for the unbiased reviews and all the intel you share. Thank you.👌

it's hard to believe that the differences we hear even in compressed youtube audio is only from changing cable. This is like different equalizers in use. So clearly diifferent. If these are only cables "talking" then i am not talking, because don't know what more to say for non believers of different sounding cables. Thanks for showing.

Actually on my speaker setup song A sounds better. But thats a thing of the setup. I have listened on my old HP PC .... with my old Vintage amp and my new M Audio BX8 active monitors. They like a bit more harsh sound, because the setup is really warm but also washed out in combination. Cables depend mostly on youre system. I just bought Audioquest Evergreen cables because its said say make the highs and mids a bit cleaner, thats what my system needs. I use ketchup cables right now, lol.

Ha ha... There is definitely an audible difference listening on my AKG275.. but guess what, I liked A 😂 my ears must be horrible 😁... But at the end of the day, I am surprised that cables do make so much of a difference 😳

After the harshness of cable A gets choked by KZfaq, it ends up sounding as "more clear". KZfaq makes it tough to hear the nuances. Even after knowing the answer, and your explanation of what you heard, all I hear on this end is B has a "smoother" texture. Thanks for the demo though. 😎👍 I'm getting good results with cable upgrades kn my system. Each upgrade makes additional upgrades worthwhile. I'm enjoying the journey 😎

I always make my own cables. I only pay a tenth of the price, for true high end cables

Thank you youtube, that I found this channel. So many things I was interested in, explained really good here.

Hi, I wanted to thank you for this video as well as the one about power and digital cables. To me that's one of the best proofs on internet and YT particularly. I'm wondering why no other youtubers do that because this is a pretty easy way to prove all these guys are wrong. And this believe keeps continue and you kill it very easy. Greetings

Cable A was catching EMI noise. The ultra cheap have cables have just poor isolation and too thin wires. RCAs do not need to be expensive, but they need to be well isolated and have enough copper inside.

I think this is a great video. People tend to justify their own status and judgement. If people try to open their mind and accept what others’ are claiming usually results in mutual respect. Audio theory, science, whatever you call it, whether it was real science pr just a placebo effects, still real. Cables do make differences. Tonality, body, weight of sound. I have experienced the changes with speaker cables, power cables, power conditioners, interconnects. But I have to be honest that I cannot hear the differences with LAN cables and USB cables. But don’t I believe in people claiming there are differences? Yes, I do believe them. If you have a small wooden peck in the middle of your sound system, that little thing changes the image of the sound and sound stage. Audio is science. But also psychological, our own body conditions affect how music sound time. So try things… don’t disrespect others just because you think it may not be the case. Respect others. Audio is a wonderful hobby.

Nice video, keep the good job! (Strange but cable A sounds better for my taste!)

Before hearing your explanation I was going to select cable B as being smoother and more solid.

I feel validated. This video confirms that you should not cheap out on stuff. That cheap thin RCA cable you used looks like the ones I have ten of in my cable drawer. Cables that were included free next to random stuff I bought my entire life. The RCA cable I'm using was sold as car audio equipmet. A nice thick blue plastic rca cable for around 10 euros. It is more quality, more durable and robust than the scraps I already had, but it is worth it. A 200 dollar cable probably sounds even better, but it would give diminishing returns. And considering my setup costs 200 dollars alltogether, I am not the target audience for it. (Besides, if I had that much money to spend on a cable, I'd want it to look cool too. Like those weaved and twisted cables ZReviews uses all the time)

I don't think it was about which cable is better, but to prove there is a difference between the two cables.

Listening on Sony A9H , Android YT app, eARC to Denon 4300h, to KEF Reference M2. During the video cable A was brighter, but also more airy, and to some degree, more transparent. Cable B mead more full sounding, definitely more low freq information, still airy but without brightness. Good video overall, thanks for the healthy attitude to the issue.

B's soundstage is so much more than A. B is more open and has less harshness.

Massive difference!! And that’s through my AirPod pros and iPhone 12 max. 😮😮😮

I can hear the difference. B is clearer and more substantial, the vocal is pinpoint and there is depth to it. A is somehow diffuse and has less clarity. Oh no! 🤣 I am still using the $2 rca cable connecting my Dac to the power speaker. I think I will have to get a better cable after watching this review. Thanks!👍

actually it's not fear to compare trash cable with high end. it will be more interesting to compare smth which costs around $20-30 with the expensive one from your friend and I'm pretty sure we will not hear any difference in that case. I'm sure about that because I did the same tests for myself many times

The difference is huge. Can't say wich is best but there is it.

This is a fascinating subject, I definitely heard a difference on track 1 and less of a difference on track 2, I am using decent headphones just through the computer. Over the different media and with all the mucking about I liked A on track 1 and B on track 2 though it was hard to define.

B sounds like a flat wall of sound coming towards my ears, A sounds 3 dimensional and spacious. Damn I ain't spending shit on cables now, ty sir great vid.

This channel is the truth.

Thanks for this fascinating demo! Going cheap vs expensive on speaker cables and interconnects has been bothering me for awhile. I just ordered some Blue Jeans speaker cables (with banana plugs), which are not at all super expensive. But, they are definitely way more expensive than what I am now using. If nothing else, I will know that what I spent a little bit of cash on is not detracting from the sound as much as what I was using before, even if it will be difficult to hear the difference plainly. Thanks!

14 Gauge copper lamp cord 49 years ago and the same today.

I've been listening to this debate for 40 years. People used to tell me that I do not hear differences! Excuse me? My literal response was, you are going to tell me what I hear and don't hear with my ears and brain? Are you sniffing glue? I agree with you and choose not to debate it with others, even with my brother lol.

You swung me, first cable video that got me thinking about upgrading. Years ago I swapped out my reasonably expensive speaker cables for solid-core copper lighting cable and I heard absolutely no difference, so I’ve been a bit of a cable doubter until now (especially power and USB). Interestingly the harsh & bright Cable A sounded “wider” to me, I guess that’s a result of more high frequencies?

Pro audio tech with 47 years experience here. The most important things in a cable are: 1. Good plugs. They have to make good, solid, continuous connections to the jacks, both center pin and ground. Shouldn't be too tight, though, or you'll damage the jacks inserting or removing them. 2. Good strain reliefs and good soldering within the plug bodies. Gotta keep the signal intact between the plugs and the wires. 3. Good shielding. None of this BS unshielded twisted pair. Good shielding = low noise. 4. Last, and least, the conductors themselves. As long as they conduct, and do not short-circuit or go open, they don't matter, provided the first three requirements are met. For a good 1 meter stereo RCA cable, you should not need to pay more than $10-$20. Make them yourself for even less. But be careful of the plugs! They're the most important thing! NOTE: For unbalanced RCA cables longer than about three meters, you need to have low-capacitance cable, or you'll lose highs with some gear. Turntable cables should never be more than two meters long, preferably just one meter.

I ‘m a Atlas integra rca owner and the uge difference whit cheaper cableis is in soundstage and timbric. Obiously, by KZfaq isnt possible hear this.... very good middle class cable.👍

Thank you so much for your honesty.It made me decide to go for a more expensive cable.

I'm really new to sound systems and honestly, can't really have a proper objective opinion about the topic, but I honestly think the "middle ways" is often the best. Without having any comparison, I choose to go with the cheapest "Tower" line cable of Audioquest that is at least "Brand-name" and seems to be trusted. Yes, they cost more than average, a random cable for Amazon is like 10 euros, a Tower one is like 20-40 euros depending on length and type but isn't that big of a deal (IMO). Seeing this video really made me happy because I know maybe I didn't wasted those extra bucks spent and probably, I wouldn't need anything more if on yours expensive system you sad you can be quite happy with a 10 dollar one from china! So all of this to say: Thank you!

A is like a Flat no effects or reverb B it has reverb effect. U can see the difference in personal if sit in the sweetspot.

Thank you for your reasonable review.🙏 I think B was a better sounding cable. Wtaching from Sweden.

5:28, B is the $200 one, at least the better one, wider and clearer sound. A is muddy. Let's see. I want to this lot ago, great job:)

Even with Bluetooth headset using mp3 compression i was super skeptical i would hear ANY difference but just the cables going from my dac to my Bluetooth transmitter to my headphones its almost as if i got a pair of new cans, incredible!

Big difference! I didn't even know cable differences could be heard via youtube compression but you just showed that the differences are even bigger than comparing two phono cartridges of the same lineup from one brand. wow with that said, I prefer the cheap cable A! More natural

I listened through my rig and also with headphones and I would say the sound difference is almost imperceptible, but there is a slight difference and I felt that the 'B' cable sounded a little better, there seemed to be a slightly increased depth of sound with that cable. The 'A' cable seemed slightly more muffled. It would have been better if you played the exact same music in both cables rather than continuation of the same piece of music. I also paused your video after the music and returning to the time stamp where you started the test 4 times. I wrote my previous comment before continuing on in your video to the point where you identified them. So my assessment was honest based on listening the best I could. The more expensive cable is in fact better given what you presented.

Highend tires benefit a highend Ferrari, not a hyundai. In other words, audio rigs that don't show a difference is probably a hyundai.

Thanks for the good video I do not buy interconnects anymore. The 'good' ones are too expensive for what they are. Now I make mine out of 1mm 99% silver wire wrapped around teflon tubing with teflon tape between and over ('plumber's tape). You can run a ground down the centre from one end to achieve a near balanced state. Finish in simple braid. You can use good to high quality RCA jacks. Another KZfaqr uses furniture piping for the centre with calico wrapping. The look pretty impressive but I am OK with what I have.

So I hope your friend treated you to a nice dinner :-D I enjoy your channel and reviews. Keep up the great work!

Massive difference imo. Amazon Basics suiting me though. Shows that those "free" cables that come with some equipment are at least worth spending just 10 or 20 bucks replacing though.

Great content, great explanation, great personality, want more vids from you! Subscribed!!!

Thanks for making this video. Its a touchy subject which means its interesting. Agree, pay attention to signal path.

I'm not sure about power cables. But please do a A/B with a good affordable set of speaker cables, sub 100 dollar and maybe regular speaker wire that comes in a roll. You've made a believer of me, but now I wish to verify all hubbub about cables.

Try Blu Jeans LC-1 in the range around $30. They claim 12pF/ft capacitance and .17 uH/ft inductance. Also, Mogami in the $60 range

Significant difference, definitely ! Been using better grade cables ever since a demo of Monster Cable, back in the 70's.

@ 4:40, It seems obvious to me that Cable B is more extended in Bass and Treble than Cable. Cable A also Blurs notes especially Bass notes. Cable B Rings beautifully the guitar strings. I reckon the extra money buying Cable B is worth it.

Really good review for me. I listened with my eyes mostly closed, just opening from time to time to check/confirm the cable in use. Definitely to my ears cable B is what I prefer. Having just bought a pair of Q Acoustic 3030i speakers which are at the top of my (wife’s) reasonable investment limit (for my hobby), I’m going to test my $6 cables against some $2 cables. I’m fairly sure that I can see some new $10+ cables heading my way. Thanks, really helpful.

We're on the pro end, studio and live sound. Most people cannot hear a difference in short cables like these. With 20', 30' etc you're goinna instantly hear the difference. Sometimes we use 50' cables, "after" the signal has gone through a 150 snake. Thats 200'. If that 50' cable is unbalanced or not well insulated, you're going to get a ton of noise via EMI, microphonics, and build quality. Yes, cables make a Big difference, but that difference is not very audible in a 3' cable. Change those cables out to 30' cables and test it again, you"ll be amazed at what you find. We build our cables from quality component's, and then cover them with Tech Flex noise isolation and emi isolating sleeving. Dont spend $200 on a three foot cable, but dont buy the $3 one. Spend $25-$30. You'll not tell a difference between one of those and the $200 one at 3 ft.

Excellent. They were very different. Excellent to point out that if you measure two things looking for a difference and there is none, you are measuring what is the same about them. The difference is beyond the scope of the measurement being applied. Cables do matter! Could you do another test where the plugs on the cables are the same. Plug quality is important. The plugs differ in too many ways to be ignored.

I am currently (excuse the pun), wanting to buy an interconnect cable for lap top and speaker combination. The review was interesting. To my fussy ears, 'A' sounded more involving, a bit brighter with a better spatial sound stage. 'B' by comparison, was more refined, but tailored, and therefore less engaging.

Definitely A is better for me. A has a more open, airy, clear, and livelier sound. B sounds slower, thicker, and more veiled.

Awesome. Great way to deliver this controversial topic. Just in time. Ordered a hand made cable and ordered my own bits to make my own cables and see which ones I like better.

It was starkly apparent that the cables sounded quite different. To me cable b was easily smoother, less congested and harsh sounding than cable a.

Excellent review

I'm into car audio. The more expensive power ground is extremely important. Cheap cables make things HOT. Learned from experience melting fuse holders and terminal blocks. The more expensive rcas help keep alternator interference coming through speakers. Good speaker wire important too. No argument from me.

I thought the B had better tonality (less sharp). I notice this with IEM cables the cheaper ones produce a sharper sound. But with IEMs its not cost, you have find a great cable for cheap. But they do matter. I think Copper or silver plated is the level you want to get to (which isnt expensive). I dont believe pure silver is necessary
