My understanding is that much tv or movie video content these days is multichannel and using a 2 channel stereo for sound is not the best approach to be able to properly discern voices and such because the sound is mixed for that format.
So I ended up with a Samsung and I went with a multichannel soundbar designed for the task as an experiment rather than defer to a 2 channel stereo by default. I think was a good choice. It even does a decent job with music but not on par with the 2 channel stereo it shares space with.
This was a midrange Samsung. My understanding is that some new Sonys actually use a technology where the screen surface is used as a speaker essentially and reviews seem to indicate that approach actually works quite well to deliver high quality fuller range sound.
