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.

"accept files via ethernet, or only by streaming. I would prefer the wired connection."

Streaming is either by ethernet or wireless. Both original and 2nd generation Apple TV's stream music via both wired (ethernet) and wireless. Not sure what you mean by "accept."

The original Apple TV had a hard drive that allowed you to physically move files like music or video onto and play directly. The current 2nd generation Apple TV does not have a hard drive so streaming music from another source, such as a computer on the same network is the only way the 2nd gen Apple TV plays music.

I have not heard an audible difference between playing files directly from the hard drive on my original Apple TV, streaming them to my original Apple TV or streaming them to my 2nd gen Apple TV.
I do not have a wireless network and connect my 1st gen ATV via ethernet to download.
It is my understanding that once HDMI is connected on the AppleTV the digital out signal is nul -
