Neotech Premium Oxygen Free Copper and Ultra-Pure Ohno Continious Casting Cables.
Unidirectional UPOCC, being free from impurity (up to 99.99998% pure copper) has no 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 the state-of-the art conductor materials for the audiophile cable industry.
