Hey everyone
I've got a few digital sources hooked up to my system and I'm frequently comparing DACs. I'm looking for a better way to switch between them. Right now, I'm using a cheap external switch box, but it's not ideal and adds another cable going to the DAC.
What I'd really like is a professionally made switch built right into my DAC's case, so I don't need any extra cables. What's the best approach for switching coaxial and S/PDIF inputs?
I'm thinking a basic rotary switch probably isn't the right way to go, am I right?

I would just use a plain old rotary switch, probably with gold plated contacts to be sure it won't oxidize, and use 75 ohm lines for the connections to and from the switch. The switch itself is bound to be electrically very small at the frequencies used for S/PDIF, so I don't see any reason to use a fancy RF switch.
