Ended up getting a Sony HT-A7000 soundbar and SA SW5 subwoofer combo. The sound is good to very good and I prefer it for watching movies over the existing Roksan pre/power amp feeding Monitor Audio Studio 20s with a MA Radius 360 subwoofer. Dialog is clearer and there's better dynamics along with some nice spatial effects. Very impressed with the simplicity of setup of the Sonys. I attached the supplied HDMI cable from the soundbar to the TV then plugged in the soundbar and subwoofer. Three cables total and the auto setup synced everything and calibrated the room within 10 minutes. And that's with me actually reading parts of the manual. The build quality and design are high quality, but there's a lot of tech built-in to the soundbar so if anything goes wrong years from now it might not be repairable.
Under no circumstances mistake the Sony combo for an ultimate home theater audio system. It's more of a lifestyle product that addresses a specific consumer type. Someone who values quality sound, but only wants a limited number of boxes, speakers and cables in the room. Additionally, I can stream TV with only one remote (Roku). That's a big deal for me.
