Streaming from a TV

I am setting up a nice system in an audio/video room.  I am trying to think thru how I'm going to play movies and music thru a TV with a nice DAC.  I will probable stream music through a streamer when I am listening to music but I would like to take advantage of my nice equipment when watching movies.   Is there any streamers that I can run the toslink from my TV thru that will clean the  signal and maybe change the input to the DAC like a DDC.  I know I can run straight to a DAC if it has Toslink but it won't sound as good.  How good would the Denafrips Gaia be if I just streamed from a laptop and ran the TV and laptop thru it?  Would I need this if I get a really high end DAC?  II know there are plenty of people doing this same thing so let me know what you are doing in your setup.
