I'd think that might be characterized as good ol' critical thinking, eh? Do power cables make a difference to sound quality? 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. note: 99 times out of 100, its the room and the air around the speakers). If you dont have any or cant find them, any cheap set of interconnects will work just fine. Then PUT THE JACKETS BACK ON BOTH OF THEM, JUST AS YOU TOOK THEM OFF, Do this (take the jackets off and put them back on again) two or three times, until its easy to strip or replace the jackets and you can do it in just a few seconds, (NOTE: To make sure that you always put the same jacket back on the same end of the same cable you took it off of, its a good idea to mark the jackets and the connectors of your cables before the first time you take the jackets off). The device Samuelsen is usingthe noise makertakes broadband A/C noise and makes it audible. Thats pretty damning. The difference in sound is not related to conductivity capacity because we adjusted the sizes during testing to account for this. We used a loopback on an audio interface in order to measure the response, so theres no measurement data that could have been altered or affected by the room. Sometime back in the last decade, I purchased a Shunyata power cable from Music Direct, who was having an overstock sale. Which is of course why Shunyata wants to show you measurements sometimes. (I'm no electrical engineer btw. 1: Length and diameter of the power cord The length of your power cord should be chosen based on the distance between your television or hi-fi and your wall socket. This is not always the case. Crazy. So why don't we ever see from Shunyata or other manufacturers comparisons of of the AUDIO output (e.g. Especially, when somebody makes actual measurements of physical conditions - like noise on a power line - that conflicts with your own belief system. 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. It's why science goes to great pains to reduce those variables. Aside from my wife, who is a musician and gets an emotional rush from reading sheet music (not a lot of help), I don't need to impress anybody else. Its a lot less effort to just buy a product thats going to be a lot more easy to use and durable from the get go. 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. Personally, I think being honest with myself is fundamental to doing things. I'm channeling responses I've seen from electrical engineers and various technically knowledgeable people who I have seen take on the claim of Shunyata and other cable makers). Im not familiar with this model, but Im relatively confident that 15,000.00 is a bit much to be spending on anything audio-related unless youre setting up a concert in a stadium! The price is around $350.). Saves money, time, product size and weight, and so on. We will let them address the issue if they desire. (This is to connect the common mode current paths typically found in an actual home audio system.). Everyone agrees that speakers sound different. If you want something with interconnects and shielding that a tank couldnt bust: thats also great! Introduction: There are a lot of misconceptions about power transmission and power quality that make it difficult for some people to understand why a power cord makes a sonic difference. What method have they used to determine the measurable difference is audible? The reason I used a wire coathanger here is to illustrate that the improvements in performance are minimal at best, imperceptibly small at worst. Theoretical performance of a power supply is very different from actual. In the first case, a single test instrument, imperfect as she or he might be, is observing the performance over a variety of conditions. In any case, all of the other questions fall roughly into line with what we expected to see. "Since a power cord is composed of a hot and neutral wire that the component sits between, a change in the length of the cord will increase the size of the "buffer" around the component. Coils and chokes are necessary in most components and I prefer "single layer wound" types such as the foil designs. Do Audiophile Cables and Power Conditioners make a Difference? Can Power Cords Have an Effect on an Audio System's Sound? If you have the absolute worst case scenario, you may hear a difference. Power Cable upgrade - do they make a difference | AVS Forum The lower the capacitance the better the cable performance. Especially, when somebody makes actual measurements of physical conditions - like noise on a power line - that conflicts with your own belief system. Sub woofers (speakers too) operate at what are considered to be very low frequencies. Plus, I don't review gear, so I can choose whatever criteria for evaluation I want. (Horrors!). The misconception goes: "I wasn't expecting to hear a difference, but I heard one, therefore it wasn't due to expectation bias (hence any sighted bias).". That way, we can achieve results that will be representative of what youd encounter in real life as well as in a perfect anechoic chamber. Not like filtering water twice. It is between two power hoses and the current is oscillating back and forth. Which is a straw man characterization. What do you think happens during a hearing test? On the second comparison, the high-end cable very narrowly edged out the coathanger 39.8% to 36.8%. Nothing.

The success of such an approach is completely dependent upon the specific design and the reactance of the power supply of the component to which the power cable is attached. Listening for differences tends to get you concentrating in a way you don't normally concentrate and the mere act of changing your concentration around can influence the outcome. Heres a very simple experiment that anyone can do at home that should prove to most peoples satisfaction whether cables actually influence the sound of a system and whether or not factors other than just resistance, capacitance, and inductance can influence the sound of a cable. Anything the Shunyata does can - and will - be re-done by the power supply by definition. (Its still being studied, from what I can tell.). Cables, Roger Skoff proposes the ultimate do-it-yourself test to prove that cables do sound different and its all about the dialectric. The object is to cut all the way through the plastic jacket WITHOUT cutting (or even nicking) the braided (or served) shield under it. Some others weren't as good. Consequently, you should probably just stick with Monoprice, Mogami, or AmazonBasics for your audio cable needs if you dont care about how they look. Good on them! You've got to be kidding. Shunyata's plugs would very likely nullify any noise reduction they achieve. But one did *seem* to alter the sound of my system. We often harp on the fact that nobody needs audiophile-grade anything around these parts, but where we make our name is proving it. Then I took it out and put the previous cable back in place. It is also proven in listening. Even a cheaper DAC like Behringer shows that such sensitivity is due to poor DAC design than anything to do with USB cables. Power = Current x Resistance = 32 x 8 = 1024 x 8 = 8192 max peak watts of power. What I find unfortunate about this is that people who fall for these demos are theoretically insulting themselves by insulting their choice of equipment. Theres absolutely no reason to sit at home and solder up your own network of coathanger cables, because theyre just too unwieldy to use. "A speaker cable conducts an audio signal from the power amplifier to the speaker. Giving good reasons for skepticism isn't dogma; it's the opposite. Please point me to a published test of an amplification or source component's noise floor where: 1. And doesn't it make sense to withhold a conclusion until it's been satisfactorily demonstrated? As best I can tell, very few - maybe no - manufacturers of audio equipment ever measure the effects of these noise currents on audio systems using their equipment. As I said I hold no a priori belief that AC cables can not make a sonic difference. Do power supply units/cables make a difference in sound quality? Excluded are . We got a hair under 3,500 responses for our comparisons, and the results were interesting. That's a high-end Shunyata cordthis one costs around $1500, far less than the most expensive cords on the market--coiled up like a snake or a slinky. Theres a reason the normal cable designs havent changed in the better part of a century. For example, buying a more expensive cable will sometimes net you a lifetime warranty, reinforced terminations, or even being able to be bent (unlike rigid coathangers). I take it none of you have actually listened to a system (or tested one) with Shunyata power cables in place. 3. 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). Let's look at the factors you should always consider when selecting a power cable to power your devices. It just means that it hasn't been satisfactorily proven or explained yet. 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. While many skeptics claim that power cables are nothing more than a placebo, there are a number of audiophiles who swear by their positive impact on the sound. That certainly sounds like a bias to me. In general, I would not recommend a power cord that is shorter than 3 feet or 1 meter in length.
