I dunno... two channel is sufficient for me, with my Klipsch Heresy IV speakers which project the sound out through the room. I also had excellent results with an old pair of Pinnacle AC850, and with my trusty Epi 100. I also think a high quality soundbar would be fine with me.
I used to have surround, but actually got tired of it. My enjoyment of movies has not diminished since I've gone to two-channel (plus a modest sub) for watching.
I'm at a large expensive house right now, where I'm taking care of it for a business associate and touring northern Nevada while I'm at it. He has an 85" TV in his big living room, with a Sonos Beam and no sub. I am impressed; it works very well. I'm sure the Sonos Arc is even better. And, one can add wireless Sonos One surrounds if one wishes, and even a wireless sub, to either model. I think such a system would be a good compromise, as the TV sound source. Easy partner factor as well: turn on the TV and the sound engages immediately, without fussing with any other components.
That way I save my nice amp, etc., for music, while the partner - who has little interest in ultimate surround sound experience and prefers simplicity - can just turn on the TV and be good to go. I'm more and more leaning towards simplicity as well.
