>>The only small differences in "RCA" cables is a "video" cable uses the shielding path as a signal return and is 75ohm coaxial cable, whereas an audio cable may use separate conductors (and be shielded or unshielded) and doesn't necessarily have to have the drain connected at both ends

Are you talking about balanced cables yere ? You pro audio guys do like your fancy-schmancy two-pin connectors
