Zune Player

I would like to connect my Zune player to my audio system. What is the best way to do this. Most of the time I wouldn't be doing this but I have a lot of music I enjoy on the player.
I don't know of any docking stations for the Zune that can pull a dgital output from the player. One could use one of the various minijack to RCA adapters, but sound quality would probably not be the best. You might be able to get a digital signal from the player using the USB synch cable and a USB adapter cable if you have a DAC with a USB input. It wouldn't cost that much to find out.
