Only problem with the ipod route is that you have to walk across the room to see the tiny little menu screen on the ipod if you want to change the music. I would prefer to use an external drive hooked up to my laptop via usb, and then use the apartment's wireless internet network to beam the signal across the room to the dac. Several folks re-clock the signal coming out of an apple airport express for this, to great success. other products create their own wireless network, like the audioengine product. i don't believe this one has fixed outputs, but you can use the optical output to connect to the DAC of your choice at your audio rack. Be careful not to use a dac that transmits wirelessly using blutooth, sound quality might suffer.
Also note, most high end USB audio solutions are not wireless, at least not that i have heard.
