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

If you only need internet radio then a simple fix is an Apple TV which has internet radio built in, is wireless, and can be controlled by an iPhone. The big plus with one is you can then AirPlay either from your computer or, again, an iDevice which then allows you to stream any music service from whatever you are using.

The Apple TV has an optical digital/analog out which you can use to hook up to your dac.

Oh, and it's $100.
