a great way to get started is with an EVM kit from Texas Instruments -- here's the homepage for their development board site -- you'll probably find a DAC which requires external power. the PAK modules come with a CD-ROM, cables and a mother-board.

My project that I'm working on meets a lot of your requirements:

http://www.head-fi.org/forums/f6/jambo-dac-288159/

Uses WM8740 DACs which may or may not reach your quality specs. Schematics are in that thread, take what you need for your design or I can sort you out with a kit soon.
