10 Audio Cable Myths and Facts
In a sea of audio cable industry snake oil, we’re sure you’re wondering, What really matters when buying cables?Save your money by avoiding overpriced cables with outlandish claims. Below are some common myths to look out for and some important things to consider when buying audio cables.
CABLE MYTHS1. Conductor skin effect
In some applications like power transmission lines, an electric signal tends to travel through the surface of a conductor and avoids traveling through the center of the conductor. Many cable companies claim that their design limits the skin effect and measurably improves your sound.
The TruthWhile skin effect is a very real issue for large scale power transmission, audio signals are in such a low-frequency range that the skin effect is negligible at best. The skin effect is only an issue in high-frequency applications. 20kHz is the highest frequency that humans can hear. If we calculate the skin effect on a 12 AWG speaker cable like Gene from Audioholics does in this article, we find that the skin effect results in a loss of only -.014dB. Your speakers, room acoustics, and the human ear have a much larger effect on your sound than the skin effect.2. Cable break-in
Don’t be fooled - any company that claims this thinks they can trick you into hearing better sound after a month or two. “Break-in” is a commonly used term throughout the industry. It is the idea that the dielectric of a cable changes and aligns itself to the electromagnetic field of the signal traveling through the conductors.
The Truth
There is no scientific evidence to support the idea of cable break-in, but there are still those who claim it improves sonic qualities. We’re not against optimism. We’re just not full of crap. Don’t drink the audio industry kool-aid and save your money for legitimate cables.
Cryogenic treatment is the process of freezing cables to -320 degrees Fahrenheit before use. The claim is that freezing the conductors of the cable at ultra low temperatures aligns the crystalline grain structure of them resulting in desirable improvements.
The Truth
Again there is no scientific data to support this notion. Cryogenic treatment can improve the durability of certain metals, usually steel, by stabilizing impurities. For example, the process is used to create strong tools or car parts.
But, steel is a terrible metal to use for audio cables. It is one of the least conductive metals out there! Copper and silver are the best conductors of electricity and the preferred metals for audio cables.
4. Cable signal direction
You might hear this phrase tossed around quite a bit. It’s the notion that a cable has an established signal direction, the direction in which it was initially used, and that this signal direction should not be reversed.
The Truth
The reality is, assuming the connector ends and terminals are the same, the cable will work in both directions and the performance will be equivalent.
5. Cable elevators, risers, or lifts
The claim is that the cables’ magnetic field can interfere with the surface it is laying on. Essentially, the magnetic field can “reflect” from the surface back into the cable and cause distortions.
The Truth
There is no evidence to support these claims, and these unnecessary devices are merely for looks. They are in no way proven to improve cable performance.
In the modern age, wireless signals are all around us all the time. The rapid growth and spread of technology means that these wireless signals will become more widespread and more likely to cause unwanted interference. Cellphones, wifi, and Bluetooth signals can enter your cables, but shielding can block these signals and preserve your sound quality.
No matter how well a cable is designed, cable length will always impact performance. As the length of a cable goes up, so does the risk of unwanted interference and signal loss. We always recommend keeping your cables as short as possible, but we understand that is not always possible. A well constructed and shielded cable will help combat this issue.
The best conductors to use for audio cables are pure silver or pure copper. Both are valued for their high conductivity, but copper is more widely used due to the high price of silver. Additionally, some variations are constructed with silver-plated copper. However, because the metals have different conductivities, the sound is more likely to travel through only the silver plating and not the copper.
The purity of the conductor will affect performance more than anything. Look for Oxygen-Free High Conductivity (OFHC) conductors. This means that a significant percentage of oxygen and other impurities have been removed from the conductor resulting in high purity.
4. Wire gauge should not be overlookedThe amount of wattage your system is using will determine the total gauge size needed for safe and optimal performance. The standard is 14 gauge wire minimum for the transmission of 250 watts of power. Many electronic devices use much less than this, but some speakers and listening setups may be using more. If your system uses more than 250 Watts, we recommend a higher total gauge cable.
5. Quality connectors matterTruly, the best connectors are no connectors at all. But, if you can’t hardwire your system, gold plated connectors are the industry standard. Gold plating exhibits great corrosion resistance when exposed to oxygen and has good conductive properties. Connectors range from basic to extremely high end and flashy.
The bottom line is:
Choose connectors based on your personal needs and the type of connection being made. Overall, always choose quality connectors.
We hope these myths and facts will help you choose quality, reasonably priced cables to complete your listening room, studio, or whatever your setup may be.

“When you can measure what you are speaking about,
and express it in numbers, you know something about it, when you cannot
express it in numbers, your knowledge is of a meager and unsatisfactory
kind; it may be the beginning of knowledge, but you have scarely, in
your thoughts advanced to the stage of science.”
Lord Kelvin I read that article Bigkidz posted from the Audio Note website. However, no NUMBER are given other than for purity of copper. Resistance, capacitance, inductance, all of these can be expressed in numbers. If they provided numbers for these parameters and show that there are indeed differences from one type on interconnect to another, then I can at least accept they know something about this. In the absence of such numbers, as Lord Kelvin said their knowledge is very limited about the subject. |

"As a newbie to this arena, I utilize sites like this to learn from the elder, more experienced, more knowledgeable in the craft. As an engineer I truly enjoy the science behind each and every detail and yet enjoy the discovery of sound when the ear is the sole compass. But what I don’t understand is the cannibalistic nature of many members on sites like this. What is it about this topic or this hobby that creates such divisiveness instead of an accepted brotherhood?" It's hard to have an "accepted brotherhhood" no matter what the arena when there are views that are totally opposite. It's like being for or against abortion. The one's 'against' literally call the ones 'for' murderers and worse. It's kind of the same with this subject. The one's that believe that science proves their side literally call the other side idiots, morons, fools and all kinds of other derisive terms. It's hard to respond in a brotherly manner. Besides, since you're a self-proclaimed newbie, maybe you don't know that this has been beat into the ground for the past 30 or 40 years already and most people are sick of it. |
