Pure Silver Wire is your good choice.The transmission of copper wire to high, medium and low frequency is relatively uniform, but there are many common copper magazines, so it is not suitable to make audio signal transmission lines. Japan used oxygen-free copper OFC more than 20 years ago. Due to the reduction of impurities, the sound tends to be clear and transparent, but it is not good for low frequencies. Therefore, with the improvement of smelting and annealing methods, large-crystal oxygen-free copper LCOCC and single-crystal oxygen-free copper PCOCC have appeared, making the sound more balanced. The sound of silver wire, because of its low impedance to high frequency, is better than copper for high frequency transmission, but sometimes it is excessive, and low frequency performance is average. The theoretical basis of the silver-plated wire is the skin effect and the best conductivity of silver, but the electrons may not all go to the surface of the conductor, and the conductivity of the electrons may deteriorate when they pass through the interface of silver and copper. High, it is not as good as pure copper wire. The deterioration of the performance of the metal signal wire is caused by chemical reaction, so the wire made by electroless silver plating method is not good, and the copper wire is covered with silver wire mechanically.Pure Silver Wire is your good choice.
