ODAC Output Switcher

Yangorang's ODAC Output Switcher album on Photobucket
I wanted to use my ODAC as my central PC audio device so I needed it to be able to output to either 3.5mm (to headphone amplifier) or RCA jacks (to active monitor speakers), but I didn't want it outputting to both at the same time to prevent unnecessary loading. I ended up implementing a tiny little board that simply routes the audio signals through a 3PDT switch to either output jack. You can see what it looks like in the image gallery above. It doesn't exactly look elegant as I more or less just glued the board to the top of the ODAC case, but it gets the job done.
