The audio cable series, LUXMAN10000, is a high-grade audio cable that is designed to enhance sound quality that we have consistently pursued in the process of manufacturing products to a higher level. Minimization of inductance has been achieved by the non-twisted structure, and high-purity transmission has been achieved by introduction of high-purity conductor and gold-plating terminal. We have also achieved high-grade signal transmission using plenty of our original techniques such as prevention of high-frequency component mixing using electromagnetic wave absorbing coat and the outer sheath structure that minimizes a loop area.
