hello. this discussion has brought me to a question. if i was to purchase a 976, i'd only plan on hooking a tv, samsung un60f8000, to it as i use the internal apps and an antenna. well, i have a chromecast too. for this set up i've been told not to use the hdmi arc ("professional installers never use arc", whatever that means) and to just use the digital audio out on the tv to something like the 976. so my question is: hdmi arc or digital audio out/toslink from tv to something like the 976? in case it might be helpful. i only have 3 large speakers (b&w 803's, htm 1), fronts and center and don't plan to expand beyond that for the time being. appreciate any thoughts. thank you.
