What is the result of testing whether you can listen and split out a terribly high audio LAN cable?

ByFlattop 341

In order to listen to music with good sound, you need to care about various sources such as sound source, equipment and environment. Especially, high-end equipment of acoustic equipment is known for its value to be extremely high, and as it begins to settle down, there is no end "Audio swampIt is also expressed. One such equipment is the Ethernet cable "Ethernet Vodka" for ultra high-end audio that costs more than 40,000 yen at 1.5 m,Disassemble and thoroughly check the contentsI did a test whether Ars Technica who did it really can distinguish whether the sound will change if I use this cable.

"Ethernet Vodka" is a high-end audio cable makerAudioQuestLAN cable for audio, which is sold. It is used for connection between computer and NAS. Features are bundled with multiple conductorsStranded wireIn the case of a structure, the signal disturbance is caused by the interaction of the magnetic field, so as to use a single wire conductor (solid core conductor), arrange the cable so as not to cause magnetic disturbance, as much insulation material with no distortion characteristics as much as possible It is said that it is being made sticking anyway, where it contains air of.


In the verification, Ars Technica challenges the ecashma, such as "Challenge one million dollars (about 120 million yen) to superpowers who could prove scientifically" super power " NPO organization that is doing ·James Randy Education Foundation (JREF)I chose a partner.

Test content is "Ethernet Vodka" and listen to music through cheap cables bought at Amazon. The sound source used was Bon Ivel's "Bon Iver"To" Holocene ", Tianie Sutton's"I'm With the Band"I Get a Kick Out of You", Daft Punk's "Random Access Memories'Contact', Miles Davis ''Kind of Blue"All Blues", each was used for 30 seconds each. These are not random, and the subjects select the music they want to listen from "male vocals", "female vocals", "electronica" and "jazz and instrumental."

Subjects are listened to music without knowing which cable they are in the order of cable A and cable B. At this time, half of the subjects are listening to the sounds in the order of Ethernet Vodka → cheap cable, half by cheap cable → Ethernet Vodka, and ask them in which order to hear after the end. Finally, listen to the sound through "Cable X" and apply which cable it is. There were no answers to subjects, "I did not understand", "I did not know the difference" was also accepted, and these were all counted as mistakes (incorrect answers).

In the test, if 15 or more subjects answer correctly, "There is a difference in the cable", if more than six people are incorrect, it means "There is no significant difference". The possibility that "more than 15 people will happen by chance" is 2%. As I tried it,6 people failed to distinguish between cable differencesThat is the end result. Five of these six people did not know the difference in sound when using two cables in the first place. Ethernet Vodka points out that there are problems that there are people who can not distinguish themselves, despite the fact that they are sold as "it makes a distinct difference".

By the way, when Sony announced "high quality microSD card" in February 2015, "Trusting the "ears" of engineers in the sound business department rather than frequency analysis, determine the final sound qualityIn the Phile-web article, as a result of actually hearing the sound, "The difference in sound quality is clearBecause it wrote "Such things may be unknown to those who do not understand, but maybe it is understood by those who understand."

Speaking of which, there is a thing called "Copy at the power station," as a copy of the stereotyped audio, but what about the actual place ...?
