线材与音质（Wire and sound quality） Wire and sound quality See the topic about wire in forum. My knowledge is limited, especially zhuanzhai teacher Tang Daoji AV technology book wire and sound a shared with DX. The effect of wire on sound was first proposed by the British sound magazine HI FI NEWS RECORD REVIEW in August 1977. It translated the CAN WE HEAR CONNECTING WIRES of French sound master J.HIRAGA (actually, can we hear the connecting wires?) One article. This paper makes a comprehensive study of the conductor and puts forward some new concepts. The mechanism of wires effect on sound has been recognized and studied, and the sound industry has created a new knowledge which has made many people devote a great deal of effort. The factors that affect the sound quality of wire rod mainly include the following aspects: 1. Shunt capacitor For high internal resistance signal source, the parallel capacitance of the signal line will cause high frequency attenuation. 2. Series inductance For some speakers, the series inductance of the speaker line causes subtle high-frequency attenuation. 3. Series resistance The series resistance of the speaker line affects the impedance and damping characteristics of the loudspeaker. The above 3 transmission based on the macro theory, because the audio wire length is limited, their impact on quality extremely. In materials science, silver is the best conductivity, copper second, but silver is much higher than copper, copper has become the main material. (playing very tired) 4. Wire purity Impurities in metallic materials affect their electrical conductivity, and copper materials of high purity may have a positive effect on the lattice structure. The purity of copper used the number of 9 (N) expressed as 5N (99.999%) is high purity copper, can make the conductive and higher quality, so the sound special wire generally at least is 4N, but the N number does not indicate sound quality. High purity copper above 4N is commonly known as oxygen fr
