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 are able to enjoy utterly natural, well balanced sound that gives free expression to the full musical spectrum.
