CStooner,
You could the $14K Dartzeel "Danalogue" that is about to be release. Its the LHC-208 and its an Ethernet Dac (to 384PCM (DXD) and DSD128) and 200 wpc Integrated amp in one. For darTZeel, that is very "cheap".
Otherwise, just get a Sonore Signature Rendu for $3k (Streamer) and that will take Internet input and output in RCA Spdif or HDMI (i2S - PS Audio standard). What makes this special is that John Swenson consulted on this one and it has a reworked power distribution network on the input and isolates the transport from polluting the Dac, especially via i2S (I think he uses giant magneto resitives).
An extract of his burb here:
"On isolation, I have been including full isolation between digital sections and mixed signal sections for many many years. I do not use optical isolators, I do not like them at all, I prefer the GMR (Giant Magneto Resistive) isolators made by NVE. I think they work way better than opto isolators."

Finally I think Steve is planning Ethernet input in his latest Dac
