CD players with coaxial S/PDIF output

Coaxial S/PDIF

— an electrical version of the S/PDIF interface that allows multi-channel audio (up to 8 channels) to be transmitted digitally. Do not confuse this interface with RCA (see the relevant paragraph) — although these outputs use the same connectors, they are fundamentally different in signal format. In addition, it is recommended to use a shielded cable for S/PDIF, otherwise there is a high possibility of interference. Speaking of interference, it is worth noting that the relatively weak resistance to them is the main disadvantage of coaxial S / P-DIF compared to optical; on the other hand, the coaxial cable is more reliable and withstands bending and pressure without any problems.
