What material to do the sound line no matter how good
It is best to use superconducting materials, no resistance, but now also can not do
The third is the silver line, or too expensive Due to the high frequency band of the skin effect, high-grade line with gold-plated line, or silver-plated line Or expensive In general, the number of copper wires inside the sound cable is better and better, the finer the finer the better, the larger the total cross-sectional area, the better, in order to reduce the parasitic parameters of the impact of some The sound line made of flat, the middle plus isolation or thick round cable type and so on In order to easily distinguish the polarity, the sound line is usually printed on the unilateral side of the text, or add color, and some audio lines of the unilateral core is copper tin, look at this sound line feel a white one Red two colors Now the soaring copper prices, and some audio lines cut corners are made of iron core, this sound line is available magnet sucked
The second is gold, but too expensive
