Apple TV ethernet wired server

i tried asking this question to Apple Product support but I didn't receive a satisfactory answer. Perhaps someone here can help.
I've been impressed by the functionality of this device in my multichannel system and have been wondering about using it as a server when I digitalize the mass of my music collection in my two channel system.
My plan is to use the HDMI output of the ATV to a small flat screen and the digital output into my PSAudio Digital Link 3. music files stored on a Minimac or various MacBooks which would conected via ethernet, as will the ATV.
My question is whether the ATV will accept the music files via ethernet, or only by streaming. I would prefer the wired connection.
