UP--OFC事实那种无氧铜 几N的 |
UP-OFC是Ultra Pure OFC，万隆没有给出UP-OFC的具体纯度，但万隆给出了UP-OCC和UP-OCC silver的纯度是7N,
UP-OFC又肯定比普通OFC纯度高，所以会是5N或6N。
The unidirectional UPOCC, being free from impurity (up to 99.99998% pure copper and silver) has electric resistance and practically no crystal boundaries. Accordingly, it is able to transmit electrical signals faster, and with less distortion than ordinary OFC and silver wires. All of these features make the pure OCC copper and silver the state-of-the art conductor materials for the audiophile cable industry.
