Hi, yes, sure, as long as you have set up an Upnp server on your NAS. I have music from iTunes stored on the server and some records in FLAC, which can be streamed without problems.

There is simply no way to feed in data via cable. I had not even thought of wireless possibilities when I made my statement above. Sorry.

I did not think in my answer that the NAS could send the files via WiFi. There is simply no data input via digit.cable.

No. The unit cannot receive files either.
