[Home Theater Network HDAV.com.cn] In audio equipment, the wire is often a part that is easily overlooked. For most users, the sound quality depends mainly on the device itself. For example, speakers, headphones, audio sources and other equipment is the key to determining the sound quality. As for what wires to use, people may not care much, as long as it is not too cheap.
Let’s listen to how much the impact of the wire on the sound quality is.
It is often said that only those enthusiasts will study the influence of wire on sound quality, because it is a metaphysics. If someone buys a speaker cable/headphone cable for several hundred dollars, you will definitely think that this person has a brain. I am sick or have money to spend. In fact, the author has always had this question in his heart. "How big is the influence of wire on sound quality? Is it really metaphysical?"
With these two questions, the author decided to find the answer through experiments. The object of this experiment is the instrument line. The author bought 3 guitar lines (prices of 15 yuan, 120 yuan and 300 yuan respectively) from Taobao. These 3 lines represent the low end and the middle end of the guitar line respectively. High-end level.
Next is the performance and recording, the author will upload the recording files of the three wires to everyone, this is the time to test your hearing, test whether you can hear the difference in the sound quality of the three wires (the answer will be Revealed on the last page of this article). What is the impact of wire on sound quality? Today may give you an answer.
15 yuan miscellaneous musical instrument line:
First of all, I will introduce the wire and equipment used by the author. A Taobao price of 15 yuan (not even the brand), this line is generally given with the instrument, the wire is very soft, poor workmanship, and not durable. I have been using this line in my student days.

120 yuan mid-end instrument line:
The mid-end wire uses the 120-yuan "Colin" instrument line. This wire has a much better workmanship. It uses a weaving process. It is stylish, durable, and the core can be manually soldered. It also has noise reduction function and signal. Transmission efficiency is also better.

300 yuan high-end musical instrument line:
The high-end wire uses the American audio wire “Evidence Audio†which costs 300 yuan. This wire is very well-made, has excellent anti-interference and noise reduction effects, and can be used as a professional instrument line. Many musicians also use it when recording. I like to use this kind of wire.

Equipment introduction:
The speaker uses the Wangs VT-10 tube speaker (Taobao is priced at around RMB 1,300). It is a very classic entry-level full-tube speaker with clear and full sound, which is very popular among users. The guitar uses the "Fender American Standard" electric guitar (Taobao is priced at around 9,000 yuan). For any guitar enthusiast, this piano is full of temptation like a sports car.
Equipment: Wangs VT-10 tube speaker + Fender American standard electric guitar
SONYM10 recording pen
After the wire and equipment are assembled, it is played and recorded (the recorder uses SONY M10). I used three wires to play and record separately, and selected two modes: unvoiced (the speaker does not add any sound effect) and overload (the speaker with a little distortion effect), and finally uploaded the 6-segment recording file to everyone. The next step is to test your hearing. Can you hear the difference in sound quality of the three wires? The answer will be announced on the last page.
All recording files are in WAV format, and each song is within 1 minute. It will affect the sound quality due to compression and transcoding after uploading the video website. Therefore, the author attaches the download link to the original file of each track for everyone to listen to and compare. Next, please wear headphones to listen to it~
Please download and listen
Tip: Please listen to the above 3 paragraphs of unvoiced recording, then listen to the following 3 distortion recordings (the effect is more obvious when wearing headphones).
If you can listen to these 6 recordings carefully, maybe you already have an answer in your heart. Of course, you may not have heard the difference in sound quality of these recordings. Then the author does not sell a lawsuit here, and quickly announce the answer for everyone!
First, let's reveal the answer: (Are you guessing a few?)
Unvoiced _01 recording" "" 15 yuan instrument line distortion _01 recording" "" 15 yuan instrument line
Unvoiced _02 recording "" 120 yuan instrument line distortion _02 recording" "120 yuan instrument line
Unvoiced _03 recording" "300 yuan instrument line distortion _03 recording" "300 yuan musical instrument line
I don't know if you have heard the difference in sound quality between these recordings. Take the unvoiced recording as an example. The spectrum of the three recordings is as follows. From the perspective of graphic changes, there is no significant difference in the spectrum of the three-segment recording. However, if you look closely, the spectrum of the unvoiced _01 is somewhat loose, while the spectrum of the unvoiced _03 is denser, which is expressed in the sound quality. Going up will be more full and the details will be more abundant.
Interestingly, the author randomly found three colleagues. After listening to the recording, they even guessed the instrument line corresponding to the three-stage unvoiced recording. However, after listening to the other three recordings with distortion effects, they can hardly hear the difference. They think that after adding the distortion effect (the sound will become cloudy), it is difficult to distinguish the sound quality.
Written at the end:
In fact, when playing with these three musical instrument lines, there is almost no difference in the sound, and even the sound of the 15 yuan and 300 yuan musical instrument lines is the same. However, when wearing headphones to listen to the recording file, the difference in sound quality appears, especially in the unvoiced state, the 15-yuan instrument line obviously has no clear sound of 300 yuan instrument line, and the details are not rich enough. Therefore, the influence of the wire on the sound is not a metaphysics. It is said that the price is one point, otherwise the musicians do not need to use hundreds or even thousands of instruments when recording.
