I worked with a guy who was crazy rich and wanted to build a great stereo. He went to a super high-end stereo shop and persuaded them to lend him a bunch of different speaker cables to "try out in his apartment". He was a phd engineer though, so rather than just listening to them he decided to do an experiment. He got some thick pure copper wire as a reference (got it from a hardware store because it's used to wire up domestic ovens and that kind of thing) and took his oscilloscope and measured the frequency response across all the cables. He found (as he expected) that the pure copper cable gave the best response so that's what he used to wire up his speakers. He did measure the acoustics in the room and put his speakers on metal pins on concrete blocks[1] to minimize mechanical interface between the speakers and the floor so the floor wouldn't clamp the bottom of the speakers. His stereo sounded great and he was super smug about it, including taking the super expensive audiophile cables back and telling the shop they weren't as good as plain thick copper wire.

The shops know this. High-end hifi is full of grift. It literally relies on people with more money than sense who can be persuaded to spend a fortune on components and extras that either make no difference to the sound or make it objectively less accurate. Which is why you get nonsense like directional cables, cable supports to keep cables off the floor, cables with magic insulation, magic rocks that go on top of components, magic knobs, magic creams, "quantum" anything, grounding boxes full of pebbles that don't ground anything, and so on. Also, most of the people who can afford this hobby are rich old boomers who often can't hear much above 7k on a good day.

Replace "hifi" with any other product and the sentiment remains the same. High-end houses, high-end cars, high-end clothes, high-end food, high-end technology... the ostensible quality of the product is entirely divorced from the price, because the actual product isn't the speaker or the handbag or the smartphone or etc; the real product is social signaling via conspicuous consumption.
  - rdlw 3y ago
    To be fair, with most of those, you're paying for a piece of art to some extent. I don't think anyone buying $500 cables thinks the cables themselves are worth that, they're buying them because they expect some tiny increase in sound quality which measurably and provably doesn't exist. Someone buying a $10k sweater isn't buying it for the engineering in the material, but for the perceived artistic value. Of course, there's also a grift involved here, where fashion brands can pass things off as having great artistic value just because they're associated with the brand. But at least the perceived value is subjective and not coming from something that can be measured not to exist.

  I had previously toyed with the idea of marketing "organic" audiophile speaker cables. The ad copy would have been that the cables were harvested from veins of copper dragons that lived in faraway mountains. That the sound would be warmer and richer than ordinary, industrially produced artificial speaker cables, which tend to sound harsh.

  - faustin 3y ago
    Out of all the ridiculous things, this one is actually not completely ridiculous. For low temperature physics applications, Oxygen-Free High Conductivity (OFHC) Copper is the only material that is sufficiently thermally conductive at low temperatures. I’m not an audio person, but I have a hard time imagining it would make much of a difference at room temperature; maybe similar performance with a slightly thinner cable?

- ThinkingGuy 3y ago
  I had a friend in college who worked part-time at a shop that sold and installed audiophile gear. He was a music engineering major, so he was aware of how much of what they sold was snake oil. Example: a 3-foot RCA cable that sold for several thousand dollars. The jacks were gold-plated. Not just with ordinary gold, but "special" gold. From a particular mine in South Africa. He told me once "If I ever sell that cable, I don't know how I'll live with myself." One time he and another guy had just completed an installation in a very wealthy customer's home. Hundreds of thousands of dollars on an ultra-high-end amplifier, CD player, speakers, etc. He started playing one of the customer's CDs on the systems. The customer went on and on, lavishing praise at how "warm" and "crisp" his music sounded on the new system. Suddenly my friend's co-worker leaned over and whispered, "Do you hear that?..." My friend knew exactly what he was referring to: they had accidently wired the speakers out of phase.

    My favourite variant of this is high-end digital audio cables.[1] Presumably the ones are really spiky and the zeros are really round when you use such a cable. [1] yes this really does actually exist as a thing.
    - paulmd 3y ago
      If USB-C has taught me anything it’s that higher signal integrity in more expensive cables is actually really a thing. I have usb-c devices which are so temperamental (razer kiyo pro) that they won’t run stable without actual thunderbolt cables. Even high-end fasgear 10gbps/100w cables aren’t good enough signal integrity or the camera will eventually freeze and crash. The extra thunderbolt shielding/better termination really does make a difference even if the pairs are not being used. Hdmi and DP cables also have a range of shielding and termination quality, and pushing more data through them will show the difference, especially in longer lengths that are at the limit of the spec. Everything looks good when you are only doing 1080p30, try doing 2160p120 on a tv or UWQHD 160 hz on a pc, with a max-length (2m) cable and tell me every cable is just as good. Even every DisplayPort 1.4 cable or hdmi 2.1 cable is not “as good” let alone a rando lower-tier cable with the older shielding. Oculink folks know damn well that not every cable is just as good either. Copper oculink cables are a fucking mess. I’m not saying Monster wasn’t ripping you off for some gold-plated connectors, especially back in 2000 when hdmi stated with 1.x in the name. But the reality is that if nothing else we have manifested the world where digital cable quality matters. And really the “hurr durr digital signals” thing has always been a little bit of an oversimplification, even as someone who’s said it before too. There isn’t a correlation with price in the high end, going from a $30 cable to a $150 cable doesn’t get you anything, but going from a $5 cable to a $30 cable you certainly do get better shielded cable and better termination if nothing else, and yes, it does make a difference when you are actually pushing the spec to the limit. You will definitely find out that not even all 10gbps usb-c or hdmi 2.1 UHBR cables are created equal let alone ye olde hdmi 1.3 bullshit cable.

  The age factor is so real. Once you're in your 40s, there's just no point, your ears are probably the limiting factor. The positive is that you can just embrace the convenience of 'good enough' compressed audio and wireless headphones.
  - schrijver 3y ago
    Not so sure about that, mixing engineers have to do very precise manipulation of sound and there’s plenty of them working well into their 40ies and beyond. While of course aspects of your hearing deteriorate, it should still be pretty simple to pick out the artefacts of compressed audio if you’ve gotten attuned to them at a younger age… At least for heavier compression, something like a 320kbps MP3 or 256 AAC is hard to distinguish from lossless but that’s also true for young folks.
  - Baeocystin 3y ago
    When I was a kid, the whine of CRTs was genuinely annoying, and those 'keep pests away' things hurt when they went off. I was looking forward to not having to experience that as I got older. Now that I'm middle-aged, I can tell there's a little loss around the vocal frequencies... but damn if those old tubes and pest devices aren't as annoying as ever. Ears are weird.
    - dekhn 3y ago
      I had a magic skill when I was in high school: I could walk into any computer lab and tell you exactly which monitors were on (when the computer was off). I believe this is around 15K. it looks my hearing drops off between 13k (noticeably quiet compared to 12k) to 14k (can't hear it at all).

        Hah reminded me of when I was a kid walking into the living room with a few people around many times and turning off the TV (crt of course) that was just showing a black screen. It was so loud and obvious to me. Now all the TVs seem to have bizarre screensavers
- seanhunter 3y ago
  Yup. When I used to do studio recordings as a musician, most studios have A/B/C speakers for mixing. They have the nice speakers usually on concrete breeze blocks which is what you do your first mix on, and those are equivalent to entry-level-ish audiophile speakers but not super-expensive, then they have the B speakers which are a bit worse and then they have the depressing C speakers which represent what people usually have at home. Even super-expensive studios that will happily drop 10s of thousands on a valve preamp or Neumann mic don't use any kind of fancy cable or unobtanium plugs or anything. Just regular hard-wearing well-shielded audio/speaker/whatever[1] cables depending on application. [1] There are some differences based on whether the cable is going to carry just audio or audio+phantom power and also whether it's line level or speaker level or whatever it's called. It's been a while.

      It wasn't a meme, it was a real product. A matt green paint pen. In my foolishness I bought such a pen. It was a fun thing to try with friends for maybe £10. Freezing CDs was another one. We tried that too. We were probably mildly stoned for that. This was the early nineties. It was an interesting time in Hifi. 1-bits DACs and other fun marketing blurb. I listen to CDs almost daily, on the same amplifier I had back then. I still have the CD player but it needs a new laser and controller board. I laugh to myself every time I pull out a CD with a green edge. It's a lovely reminder of my young self and my friends in our late teens.
      - hedgehog 3y ago
        Ah yes, DirectStream Digital. I think the math behind that was solid but there wasn't really any point because PCM was totally sufficient. The company I was working for made AD and DA converters for recording studios and film so we were adjacent to all the insane HiFi stuff but didn't really interact with it. We did get bug reports that were real but effectively not visible, I learned a lot about debugging from watching my boss work on those.

  - amelius 3y ago

rsync 3y ago
Just some food for thought… If you are doing long speaker cable runs and are using 12 gauge wire anyway… At some point it occurs to you, why not just use Romex ? And, in fact, it’s a very good choice. 12/3 romex - typically used in three Way lighting circuits - gives you two speaker pair in one nice package. Two downsides: First, it can be confusing for future electricians, etc., who do not expect romex in the wall to be used for low voltage. Second, stereo terminal connectors are not typically designed for solid copper and that can get a little frustrating and complicated. … but then you think about it a little more and it occurs to you: why not just build terminal blocks and make connections with WAGO lever nuts ?
- jeffbee 3y ago
  Romex is grand at audio frequencies but what's even better is just sticking the amplifier in the speaker. What you get from vanilla integrated speakers today is something that would have cost tens of thousands in the 90s and would not have been available in the 70s: dedicated amplifiers for each speaker element, with electronic crossovers and, if you want it, room correction.
  - amluto 3y ago
    If you stick the amplifier in the speaker, then you have much lower voltages and currents in the cable to the speaker, so you are, perversely, much more sensitive to noise that couples into your wiring. As a silly and dramatic experiment, touch a wire connected to a passive speaker (without power applied — don’t zap yourself!). You won’t hear anything. Now touch the center pin of an RCA wire leading to a powered-on speaker with appreciable low frequency response, e.g. a subwoofer. Bzzzzzzzzz!
    - jeffbee 3y ago
      No I have a digital connection to the speaker, because I am modern and rational.
    - mschulkind 3y ago
      This is why balanced cables exist.
auxym 3y ago
Here's a frequency response test pitting a coathanger against premium audio cable: https://www.soundguys.com/cable-myths-reviving-the-coathanger-test-23553/ https://www.soundguys.com/cable-myths-reviving-the-coathange... Spoiler: the difference between the coathanger and the premium cable is probably inaudible, and the difference between anything better than a coathanger (ie, literally any sort of copper wire) and the premium cable is certainly inaudible.
- kenhwang 3y ago
  I had the same thought when I was building out my home theater system. Cables are cables, they're all just copper runs with gold plated ends, I'll just get whatever. Well, I was dead wrong. Cheap cables hiss and hum like crazy when there's no signal. Turns what you're paying for with expensive cables is better shielding around the copper. Unless you have perfectly air gapped cables that don't touch anything electrically conductive, they'll pick up some static charge and interference over a long enough run, and it's very audible. So yeah, get half decent shielded cables for long unbalanced runs to passive speakers. Or just use balanced cables with active speakers.

        Applejinx 3y ago
        Speaker cables are literally balanced, unless you're grounding them at the speaker. I grant you that if you're grounding them at the amp it's 'fake balanced', but if you're running an amp with an output transformer then it's literally balanced.
CommieBobDole 3y ago
I seem to remember an article some years back that determined that CAT5 network cable made excellent speaker wire; though very thin, the wires were entirely capable of carrying the electrical signal, and the twists prevented interference from nearby electrical fields.
- searealist 3y ago
  Interference isn't a problem in speaker cables because it is an amplified signal, so any added noise is too little to be audible.
  - LoganDark 3y ago
    > any added noise is too little to be audible One would think so...

      https://youtu.be/TVCmPrDthlE https://youtu.be/TVCmPrDthlE
      - LoganDark 3y ago
        Whether it's "too little to be audible" depends on how sensitive your speaker driver is and what the noise floor of the room is.
        searealist 3y ago
        In the video I linked, he was unable to induce any noise into the speaker wires greater than -130db at 60hz. The threshold for human hearing in absolutely ideal circumstances is about -115db. Anything less than that is provably inaudible for all frequencies, and for 60hz the threshold is much higher than -115db. The noise floor of the room only raises that further. For perspective, the very best state of the art DACs can only keep noise levels to -123db and just a few years ago the number was significantly worse.
ridgeguy 3y ago
Piker. A rich, truly obsessive audiophile wouldn't use copper, but rather 6nines annealed silver wire for those speakers.
dtgriscom 3y ago
At MIT, I had a friend who wired his speakers with flat ribbon cable, alternating conductors so as to minimize impedance. Me, I used 150 foot 18-gage twisted pair when I put my speakers down in the courtyard. I can't say the sound was perfect, but it was at least pretty good, which tells me 20 feet of the same would be plenty good inside a room. (Yes, IANAaudiophile...)

Just some food for thought… If you are doing long speaker cable runs and are using 12 gauge wire anyway… At some point it occurs to you, why not just use Romex ? And, in fact, it’s a very good choice. 12/3 romex - typically used in three Way lighting circuits - gives you two speaker pair in one nice package. Two downsides: First, it can be confusing for future electricians, etc., who do not expect romex in the wall to be used for low voltage. Second, stereo terminal connectors are not typically designed for solid copper and that can get a little frustrating and complicated. … but then you think about it a little more and it occurs to you: why not just build terminal blocks and make connections with WAGO lever nuts ?

Romex is grand at audio frequencies but what's even better is just sticking the amplifier in the speaker. What you get from vanilla integrated speakers today is something that would have cost tens of thousands in the 90s and would not have been available in the 70s: dedicated amplifiers for each speaker element, with electronic crossovers and, if you want it, room correction.

  If you stick the amplifier in the speaker, then you have much lower voltages and currents in the cable to the speaker, so you are, perversely, much more sensitive to noise that couples into your wiring. As a silly and dramatic experiment, touch a wire connected to a passive speaker (without power applied — don’t zap yourself!). You won’t hear anything. Now touch the center pin of an RCA wire leading to a powered-on speaker with appreciable low frequency response, e.g. a subwoofer. Bzzzzzzzzz!

    No I have a digital connection to the speaker, because I am modern and rational.

    This is why balanced cables exist.

Here's a frequency response test pitting a coathanger against premium audio cable: https://www.soundguys.com/cable-myths-reviving-the-coathanger-test-23553/ https://www.soundguys.com/cable-myths-reviving-the-coathange... Spoiler: the difference between the coathanger and the premium cable is probably inaudible, and the difference between anything better than a coathanger (ie, literally any sort of copper wire) and the premium cable is certainly inaudible.

I had the same thought when I was building out my home theater system. Cables are cables, they're all just copper runs with gold plated ends, I'll just get whatever. Well, I was dead wrong. Cheap cables hiss and hum like crazy when there's no signal. Turns what you're paying for with expensive cables is better shielding around the copper. Unless you have perfectly air gapped cables that don't touch anything electrically conductive, they'll pick up some static charge and interference over a long enough run, and it's very audible. So yeah, get half decent shielded cables for long unbalanced runs to passive speakers. Or just use balanced cables with active speakers.

  I mean you could just snap some toroids on there too

      Speakers can't be driven with balanced cables.

        Speaker cables are literally balanced, unless you're grounding them at the speaker. I grant you that if you're grounding them at the amp it's 'fake balanced', but if you're running an amp with an output transformer then it's literally balanced.

I seem to remember an article some years back that determined that CAT5 network cable made excellent speaker wire; though very thin, the wires were entirely capable of carrying the electrical signal, and the twists prevented interference from nearby electrical fields.

Interference isn't a problem in speaker cables because it is an amplified signal, so any added noise is too little to be audible.

  > any added noise is too little to be audible One would think so...

      Whether it's "too little to be audible" depends on how sensitive your speaker driver is and what the noise floor of the room is.

        In the video I linked, he was unable to induce any noise into the speaker wires greater than -130db at 60hz. The threshold for human hearing in absolutely ideal circumstances is about -115db. Anything less than that is provably inaudible for all frequencies, and for 60hz the threshold is much higher than -115db. The noise floor of the room only raises that further. For perspective, the very best state of the art DACs can only keep noise levels to -123db and just a few years ago the number was significantly worse.

Piker. A rich, truly obsessive audiophile wouldn't use copper, but rather 6nines annealed silver wire for those speakers.

At MIT, I had a friend who wired his speakers with flat ribbon cable, alternating conductors so as to minimize impedance. Me, I used 150 foot 18-gage twisted pair when I put my speakers down in the courtyard. I can't say the sound was perfect, but it was at least pretty good, which tells me 20 feet of the same would be plenty good inside a room. (Yes, IANAaudiophile...)
