Digital cable v. standard interconnects


This may sound somewhat naive, but what is the difference between a "digital coax cable" and standard RCA-type interconnects? Is it truly necessary to connect a digital source with a digital cable, or will any decent IC work as well?

Ezmeralda is correct but all cable impedances are "nominal". In other words, they can vary with frequency.

You can actually use any interconnect as a "digital" cable. Since "digital" is basically an RF based signal, i would recommend something that is shielded. A simple twisted pair WILL work but it is also leaking ( more like "spraying" ) signal around the room. You will notice a difference in sound between cables when doing this if your system and hearing are up to the task. Sean
