I've done something very similar, if not exactly, to what you are contemplating. I, too, use Music Match. I store all my digitized music on a dedicated external hard drive on my PC. With the use of an Audiotron (from Turtle Beach), my audio system accesses the MP3 or WAV files off the computer via an Ethernet network. Though the Audiotron does have analog outputs, I would recommend using its toslink jack to output a digital signal to an external DAC.
The beauty of the Audiotron is that it allows the user to control it from either its front panel (like any other component in your system), or from the computer itself. Any computer, actually, that is on the network. I have a wireless LAN at home, and with the Audiotron's thin net version of the software interface for PDA's, I'm able to control the music from anywhere! Not only that, but if you have multiple Audiotrons (for multiple rooms) the PDA or computer can centrally control them all, independently.
Hope this helps.
