(Its still being studied, from what I can tell.). Thats not of question, at least to me. But subtle degrees of audio performance are not the only consideration when putting together an audio system. This is a thread about power cables - imaginary perceived difference vs no measurable difference. Others are dramatically profound and sometimes surprising in their behavior. They don't show: 1. Our philosophy is to create a product that is a faithful musical component as opposed to striving for excellence in any single performance area. So power does not pour into the component at all. Some have pointed out that, of course the Shunyata presentation doesn't tell you they chose what seems to be a smaller 18ga stock AC cable to test against the higher 14ga Shunyata cable. Feb 3, 2021 I DON'T IMAGINE WiFi HiFi Publisher John Thomson realized he was setting off a firestorm when he posed the question "Do Cables Matter?" in his weekly newsletter. In every single one of the five comparisons, one sample was recorded over a coathanger cable, and the other was recorded with a high-end cable. It's really easy and glib to just pat everybody on the head and tell them that what they observe is all in their head and not real. It's almost impossible to design a power supply that is so poor that it *doesn't* already do what these filtering cables do. In that light, Im going to be chucking the coathanger cables (rather than continue to use them) once this article is finished. Electromagnetic energy can be transformed or redirected to lessen their effects. I was a bit low on funds and ended up buying the MIT Z used. Some leads are of flimsy construction, and may reduce the available power for sustained loud passages, however, the difference will rarely exceed 1dB in most cases. Apart from being flexible, it's also very lightweight. The samples were recorded at a distance of 6 away, on-axis, and repeated five times per cable. Then, using a razor blade or an X-Acto knife, very carefully MAKE A CIRCULAR CUT ALL THE WAY AROUND EACH CABLES JACKET as close to the RCA connector at each end of the cable as you can. Sometimes seeming excesses in audio really are excesses: you dont always need to indulge that upsell at the counter. On a personal note I would like to say that I was an audiophile long before I was a manufacturer of audio products. Have they controlled for well-known variables such as sighted bias? Alas, two other factors conspire to make this non-news: 1.
Do DC power cables make a difference - Audio Chews The device Samuelsen is usingthe noise makertakes broadband A/C noise and makes it audible. We also didnt prove that you can stick just any old piece of metal into your speakers or audio equipment and itll work perfectly. But, what you do is up to you, not me. Capacitance, attenuation, velocity of propagation or impedance metrics would give nothing away to their competitors but a metric by which a customer can verify that the product delivers what promises. So why don't we ever see from Shunyata or other manufacturers comparisons of of the AUDIO output (e.g. I'd like to see examples of where the noise element of an audio system has been measured and published when multiple desired tones are used as stimulation and the test gear has not been optimized for displaying minimum noise. True! The transition between the various metals used in a power cable and its connectors can cause electromagnetic reflections and diode-like rectification of the noise impulses as they propagate away from the power supply. Additionally, you dont want to be responsible for screwing up your equipment or house if you mess up somewhere and short something. for $400-$500 I would expect to have polished copper plugs. a) They make a difference. Editors note: This article was updated on January 4, 2023 to clarify language, and add FAQ. So, obviously whatever expectation bias I have is non-functional. (With its orange color, this power cord is intended for the medical industry, but the same cable in a different colorblueis available for your hi-fi. Electrons cannot be contaminated. Especially, when somebody makes actual measurements of physical conditions - like noise on a power line - that conflicts with your own belief system. On the other hand, the shielding may induce re-radiated fields onto the cable or component that it is being used in. Shunyata does have tests proving audible noise has been removed from an audio system, as well as removing mains noise from hospital equipment, where the application is many times more important. The coathanger cable before soldering to its TS termination. Answer: "The power cord is not the last 6 feet, it is the first 6 feet from the perspective of the component. Someone COULD be hearing a difference between cable A and B - that's not ruled out a priori. ]]>MAKE THIS CUT ON BOTH CABLES. Hi-Fi mains cables only make a slight difference in amp output and noise, but the difference isn't large enough to cause an audible change in sound quality. And, although I'm not a fanboy of Shunyata, at least they're trying to measure what they can. We then tested three hypotheses against all the results, and came up with the following: The only hypothesis we were able to confirm was that fewer people would choose the high end cable over the coathangerand we were unable to confirm the original hypothesis that few people would be reliably able to tell the difference between the two (we should have logged how many people were correct all three times). Everything is relative and the designer must weigh the sonic value of each part when designing a product. I could be wrong, of course. The first question is do power cords make any difference at all? Do power cables make a difference to sound quality? "Some power cords use capacitors, inductors, or ferrites in an attempt to control the electromagnetic fields around the audio component. Your test cables are now ready, and will allow you to critically evaluate TWO VERSIONS OF THE SAME CABLE, that are of exactly the same materials; the same length; the same (except for the jackets) construction; the same resistance; the same capacitance; the same inductance; the same characteristic impedance; and even the same connectors, to determine if any differences can be heard. But, generally their view of flaws in electronic systems are pretty simplistic and focus on first order effects. But, don't you wonder why this is? Learn more. OK, only just a bit. Or: "I expected the cable to sound better, but it actually sounded worse, therefore the effect couldn't have been due to expectation bias (which is then mixed up with sighted bias generally). I'm considering a purchase (about $1000) that will include a power distribution box and a couple of very good cables to service my power amp and subwoofer.. For those who have upgraded power cables, how you would describe the sound quality difference in your system? But one did *seem* to alter the sound of my system. The power cord made a significant difference in performance of the Linn, I don't know if it was because of the amp being digital or what but that was the best $75.00 I think I've ever spent. Who's right? To start, first find a set of the freebie interconnect cables that many manufacturers of cheap electronics include in the package when you buy their equipment. Although capacitance is of a bigger concern for data and not so much for audio, you can somewhat correlate the conductor's quality to capacitance. The device under test is also connected to other typical components (in other words, a source, a preamp, and an amplifier) with the other products plugged into the AC mains and powered up. Just use as much wire as you need, which is always good advice for cabling. I reviewed what I wrote and didnt once suggest that you, or anybody, should accept any claims of any kind. Reprinted from WiFiHiFi Magazine - Over the next few days, John's inbox filled up with messages weighing in on both sides of the debate. January 4, 2023 We often harp on the fact that nobody needs audiophile-grade anything around these parts, but where we make our name is proving it. But at the same time, if we really want to warrant confidence in certain claims, we can't pretend our biases are magically exempt just in our pet hobbies. I hypothesize that the power levels needed to transmit a signal to modern audio equipment far exceed the level where the difference in cables would matter, provided the gauge of the wire is sufficient to satisfy the requirements of the given system. The 25 Ultimate Audiophile Speakers of All Time, We picked the 25 absolute best audiophile speakers over $5,000., Ideal Room Size Dimensions and Ratios for Audiophile, Dennis Foley discusses the idea of ideal room dimensions --, The 10 Best Audiophile SACDs Ever Many Are, Audiophile music, particularly the high resolution disc format, can be, Paul Wilson wonders about the plethora of musical genres in, Can Power Cords Have an Effect on an Audio. My day job is in the telecommunications equipment biz. The cables make no difference crowd, which exists in large numbers here at AVS, is a kind of secular religion, IMO. As an Amazon Associate we may earn from qualifying purchases. I think it's a bunch of baloney. Really, just consider the utterly astounding number of dubious things people have become convinced they felt, experienced, heard, saw etc (attend a New Age Fair and you will find honest testimonies to the effects of every single wild device or nostrum sold. Power = Current x Resistance = 32 x 8 = 1024 x 8 = 8192 max peak watts of power. We usually call these other frequencies noise or Electromagnetic Interference (EMI). Were also not going to entertain endless questions about what equipment we used, or opposing experiences. How is this not perfectly reasonable to ask? Then you suggest that maybe the lack of measurable results is due to the fact it's too hard to measure those results. This should be true on low-power line outputs, high-power speaker outputs, and even two-channel cables. If you dont have any or cant find them, any cheap set of interconnects will work just fine.

But it's entirely sensible to recognize the variables involved, in trying to tease out reliable conclusions. marvda1 Posts: 4,533 November 2021 I know it's youtube but see if you can hear a difference. If you need a cable like this, it means that the engineers who designed your products were not worthy of the title.
Subwoofer cables - Big difference or rip-off? | Audioholics Home I also wasn't expecting that it would be better or worse. Sometimes the cure may be worse than the illness. Plus, A/B tests don't confirm the perceived gains some users report, and companies don't usually publish factual data to justify their claims. I did a blind test between a stock power cable and that Shunyata AC cable to help control for sighted bias. Think of the fun youre going to have. For the speaker cables, we took two more coathangers and bent them straight just like the last ones. I do have the testing equipment to measure cable and fiber properties and as far as I can tell the Shunyata V10NR and V12NR wires have the same properties of any cable I can buy at the hardware store. The same exact poll was posted with the same exact samples, and things got a little wonky with a different audience. If youve ever shopped at a commission-based big box retailer, youve probably had someone try to upsell you on expensive cables, gold-plated interconnects, or even specialty power cables. We will let them address the issue if they desire.
In order to determine if people could hear the difference between a coathanger and a cable, we posted a poll in an earlier version of this article. And of course the reason we have standards for producing competent cables, and power supplies etc is because they were developed through long histories of testing electrical theory! The Red Dawn Power Cord employs high-speed, low-loss, heavy gauge 3 x 14 AWG Micro Mono-Filament conductors sheathed in FEP insulation. Perhaps you want to give it a try for yourself. 2) Stiff power cords are also common and can be a nuisance. Mistrustful? But "theoretical performance of a power supply is different from actual?" Previously, I'd observed some power cords being superior, at least to me. Do power cables make a difference to sound quality?
Audiophile power cables: do they make a difference? - AudioReview Tinkering Douglas_Henning (Douglas Henning) May 13, 2022, 9:31am #1359 Graeme_Finlayson: But hey, we're talking about personal tastes in relation to measureable differences with tubes. These devices belong in the component or in a dedicated power conditioner. That's the way we are, a minefield of cognitive errors and biases. Well: let's find out! Some contend the number is 3dB for music, but as it is with everything regarding human perception: that number is a moving target. This is a good comment--thanks for the reply. And, most certainly, an awful lot of the explanations are plain hogwash. Esthetics is also important especially when the system is located in a beautiful home. Wire thats thick enough can satisfy the power requirements of the components (impedance issues), Passive speakers need a lot of juice to drive properly, and therefore any small attenuations from using imperfect conductors wouldnt make much of a difference, A cable made of coat hangers with TS terminations, A collection of oxygen-free copper (OFC) speaker cables, Coathangers stripped and prepped for use as a regular speaker wire, 122 listeners chose both sound equally as good (41.7%), 86 listeners preferred the coathanger (29.5%), 1,456 preferred the coathanger (45.5% with first comparison, 36.2% without), 1,049 preferred the cable (32.8% with first comparison, 37.7% without), 694 chose both are the same (21.7% with first comparison, 26.1% without).
