The capability of digital broadcast is excellent, but the TVs' sound are a complete joke.
I take the optical out SPDIF from our Samsung panel into a Rotel RDP-980 D/A converter and a Rotel integrated RA-970BX running some floor standing Mordaunt Short three-ways. We cannot listen to TV anymore without decent audio.
For all other audio visual sources, a Dell Zino HD410 (via wifi to the NAS) does duty to the panel via HDMI. The Samsung is set to convert DD etc broadcasts/movies/DVDs/Blurays etc to 16/48 PCM via the optical out. We love it. No surround crap, been there, done that.
