Ultimate digital to digital solution

I am interested in creating a system which doesn't have the drawbacks of CD transports (i.e. wobble, etc). I am trying to find some software for PC which will allow me to transfer raw audio files (ripped to WAV from CDs) via firewire to a receiver or amp that has a firewire connection. Is this currently possible? I know it is easy to do using coax or optical, but I want the clock sync of firewire.
DS; there is a new interface out, that will work with your pc (and my Macs) that uses wifi to stream your ripped mp3's, wav's etc from your computer, to your HiFi. Forgot the name but it is in this months issue of Mac Addict.

Sounds interesting. How does the unit hook into the receiver? Via firewire or SPDIF?
