Best value I have seen is plex on Amazon fire tv box. Box costs less than 100 and supports high res audio and video via toslink and hdmi. Plex app to run on it is $5. Does not require Amazon prime to run plex. You can run plex on smart phones or tablets and "cast" to Amazon fire tv plex to use those as controllers. Use standard hdmi to any tv for display.
Plex runs on many platforms costs virtually nothing and sounds and looks great.
