Resolution Audio Cantata
The handsome Resolution Audio Cantata ($6,495) is about as close as you can get to an Ethernet DAC. The UPnP-enabled Ethernet input allows you to connect to a NAS via the Resolution Pont Neuf and you can control playback with the Cantata app for iOS devices. There's also a cleverly concealed slot-loading CD drive for spinning discs when the feeling moves you. The Cantata can handle up to 24/192 playback via asynchronous USB, AES/EBU, Coax, and Toslink and there are fixed and variable RCA and XLR outputs.
