Q. Are digital coax cables capable of hi res audio?

Answer:

Ordinary 75 ohm coaxial cable has been used for years as TV aerial cable with frequencies in the UHF band 470 MHz and beyond so 24/384 at 18 Mb/s would be no problem for a cable like this. However with digital coaxial outputs, like all such S/PDIF outputs, they have a limit of 24/192kHz because that is the way they are designed. If you'd like to use this output on your hi res network streamer, then the Reference Digital 40 cable is the perfect choice. It exhibits lower jitter than any other S/PDIF cable because it has plugs that more nearly match the 75 ohm characteristic impedance and therefore insertion loss and jitter are reduced.
