The debate rages on. Toslink fans claim said cable is more accurate because it relies on light transmission, which has less resistance and is usually more affordable. Coax supporters argue their cable is better protected with its thicker jacket and offers a tighter connection. Interestingly, high quality RCA video interconnects have been substituted for digital coaxial with similar results since video interconnects fit the same specifications used for digital audio. However, do not use a standard RCA audio cable in place of a digital coaxial cable. In the end, your ears are the final judge over which way to go.
