The Accuphase Oxygen-Free Copper Series cables use a densely braided outer conductor of oxygen-free copper, reliably shielding the two twisted internal conductors also made of highly pure copper. The result is a high-quality cable with negligible transfer losses and excellent resistance to induced noise. The superb performance of these cables ensures that the sonic character of top-quality audio components connected in a system is fully preserved. Listeners can enjoy utterly natural, well-balanced sound that gives free expression to the full musical spectrum.

• Center conductor core wires are a combination of highly pure oxygen-free copper wires and silver-plated soft copper wires, providing excellent transfer characteristics.
• Center conductors are formed by a combination of two types of highly pure oxygen-free copper wires of different diameter and a silver-plated soft copper wire type with low resistance. The insulation layer consists of polyethylene with high dielectric resistance and foamed polyethylene, resulting in a triple layer configuration, implemented in a dual-core design. Transfer losses as well as DC resistance are minimal.
• Shielding is provided by 192 ultra-fine 0.1 mm high-purity copper wires braided to a high density, plus a layer of aluminum foil tape. This dual approach results in low capacitance and gives extra protection against any form of externally induced noise.
