Internet Radio as digital source

To make it clear , I wish to add internet Radio "TUNER " as a digital source to my 2 ch audio system. I don't know if there exists such a gear as  internet Radio TUNER or not. . I I am not lookiy for simple internet Radio with analog output with built-in amplifier and speakers. 
Can any one help  me here ? 

Check out Tunein on the web.  You can use that through your computer into your DAC.  I use it through a streamer and love it.

I agree that Tunein is a great option for listening to Internet radio stations.  Please see:
