There's another dock that extracts the digital output of iPods/iPhones/etc. it's the Pure something or other (can't remember model number). It's about $100 vs the much more expensive Wadia itransport.
Another method is the HRT iStreamer. It's $200 and has its own internal DAC. doesn't have digital outputs though. I'm pretty tempted to try it out for a headphone system I'm putting together to keep things very simple and minimize boxes.
