If you are going to do a soundbar, do it properly - get a Sonos Arc, the Sonos Sub, two Play 1's, and you'll have a wireless DTS-ready 5.1 setup. It's not ever going to sound as good as an AVR, but it will be infinitely better than just going and buying some bullshit soundbar from Amazon.
But, really, a proper AVR 5.1/7.1 setup is what you should aiming for. HT amplifier, floorstanding left and right, center, and two rears, with Atmos speakers added.
For extra dick swinging, I run a two-amplifier setup, with a second stereo amplifier dedicated just to powering the front speakers, via pre-outs from my Denon.
The sound like like magma rising up from the bowels of hell. Sublime.
