Congratulations on deciding on the new Macbook Pro. It actually comes with an optical digital I/O, which I believe is one of the mini connectors just like in your Airport express.
This does limit your choice of DAC to ones with optical input. Otherwise a USB to S/PDIF coax converter would be ideal as menitoned above. Take a look at
Hagermann USB Converter
Empirical Audio ;)
No association with either company, not even a customer yet. I heard good things about the Hagerman and it would probably be the one I would consider, especially for the price.
Enjoy!
