    Abstract: A two conductor audio cable having no delay from end to end as a function of the frequency of audio signals conducted therethrough. There are a pair of conductor assemblies each comprising an elongated cylindrical core member of a flexible insulating material extending between the ends of the cable. A plurality of strands of an electrical conducting material are longitudinally disposed between the ends of the cable along the outer surface of the core member to define a cylindrical conductor which is, in essence, all "skin". The strands are electrically insulated from one another. A cylindrical support tube of a flexible insulating material is disposed over the core member and extends between the ends of the cable and is supported concentrically about and spaced from the core member by a helically wrapped support tube.
