Digital Cables and Analog...interchangable?

Stereo interconnects are usually 75 ohm and digital audio interconnects are usually 60 ohm, so there is a difference.

Digital are 60 ohm and analog stereo 75? Here I've been thinking proper impedance for digital interconnects was 75 ohm, at least for SP/DIF.

I guess I always thought digital was 75 ohm. I know Rick Shultz at Virtual Dynamics says you can interchange them and they are exactly the same. I have a virtual digital revelation signature and have thought of getting another digital rev signature to get a pair for analog rca interconnects.

why not just try the analog interconnect as a digital cable and hear the affect on the sound of your stereo system ?
