Internet Radio - help please


Hello,
My friend just spent about $700 for a reconditioned Marantz - model???. I'm very impressed with the volume of stations and sound quality. It has an internal DAC and once set up gets free internet radio from all over the world. I do have an external DAC with RCA & USB inputs. So, hoping to make use of the DAC with another ??? device.
I'm considering an external device, not a laptop, that I could hook up to my external DAC that will accommodate internet radio via ethernet connection. Hoping to spend less than $300.
Any suggestions?
Thanks and have a great day

The Logitechs have both optical (Toslink) and coax (RCA) digital outputs.

I use mine into a EE MiniMax DAC via the RCA (coax) digital out.
My cd playback is through a modded Jolida JD100 with Mullard tubes. I'm happy with this player but did acquire an external DAC a few years ago for a secondary system that I have since disbanded.

The AUNE DAC/Headphone amp shipped direct from China for about $175. The DAC performs very respectably, especially considering the cost. It does have a COAX input so I should be all set.

I appreciate the feedback and will likely purchase the Duet very soon.
I use a Logitech Touch, and run the coaxial SPDIF output into my Meridian G68 and the sound quality is really good, (much better than I expected). The Touch connects to the WWW via Wi-Fi through an AT&T U-Verse high speed gateway.

I recently acquired a DaySequerra MultiMerge 1 which goes between the Touch and the Meridian G68 to decode DTS Neural webcasts. It connects to the Touch via its coaxial SPDIF output, and to the Meridian via the 3 MHR links. The number of 5.1 DTS Neural encoded programs, particularly APM-sourced classical programs, is surprising, and provides really great sound - much better than stereo.
I just bought a Touch via Amazon for $239 shipped for internet radio only to use with an external DAC. It took me 5 minutes to setup. If you get the free squeezenetwork account, you don't a computer but just an internet wireless or ethernet connection.
