[Home Theater Network HDAV.com.cn] Regardless of actual or theoretical analysis, audio must have a good sound, audio wire is the key link in the system. Hifi speakers, amplifiers and audio sources of different price points have better technology, amplitude frequency indicators and the ability to balance sound volume. There are no technical indicators for all audio cables. The matching of audio wires and equipment is more blind. This sticker only discusses the distortion of the wire in the system from the perspective of the balance of sound volume.
The distortion of the sound of the sound wire mainly has the following four aspects:
1. The audio system is lost or unbalanced by the wire, which weakens the information in the sound spectrum. For example, the intermediate frequency of the sound is less, the sound of the instrument resonance box is less, and the vocal resonance is less. The overall evaluation is that the sound IF thickness is a little less, and the sound can still be barely accepted. For example, the low frequency and high frequency of the audio are less, and the intermediate frequency is good. Low-frequency sound is imaginary, lacks density, detail and texture. High-frequency sound lacks detail and texture, and the extension is less. In this way, the sound is still very nice. Wires of this phenomenon are more common.
2, the sound of which frequency band feels more, the sound of this band will be tight and hard. At high frequencies, it will be sharp and thorny. This kind of sound is unacceptable. There are very few wires for this phenomenon.
3. The distortion caused by the inductance and capacitance of the audio wire. Inductors and capacitors are inevitable and more or less in the production of wires. How to use the self-inductance of the wire in the acoustic wire is a very important topic in wire design. There is little relationship between the resistance value of the wire and the frequency. The resistance is the basic data for the design of the acoustic wire. The effect of the inductance and capacitance of the wire on the sound is "the effect of the high frequency extension of the sound on the speed and transient of the sound".
4, audio wire material distortion, material purity, material crystal structure, oxygen-free body and single crystal. The material of the anaerobic body has grain boundary distortion, and the impurity is not high and there is impurity distortion. Nowadays, the materials used by audio wire manufacturers are generally high purity of several N, and the material purity distortion is very small. The grain boundary distortion is compared with other parts of the sound system, such as the inner line of the machine and the inner line of the box. There is a world-priced wire rod, which is made of silver-plated oxygen-free copper.
Conclusion: The wire structure data is the key to the design of the sound wire with a balanced sound. The material is the basis. At present, most of the wire materials used by manufacturers are better. The research and development of wire structure data, because there is no unified theory, each family has their own tricks, the estimated reason for seldom announced is mainly independent intellectual property rights. Is it possible to draw the conclusion that for different sound systems, there are very few wires that can really match the system to achieve sound balance. Most audiophiles like their own audio equipment and sound like their own children, this is really a fever. This is probably the reason why enthusiasts have a relatively large difference in audio sound evaluation. More force Mr. Liu said that enthusiasts develop toward the golden ear, first study the structure of the sound, almost every enthusiast can become a golden ear. If there is something wrong, please enlighten the enthusiast.
