OK, I've been following this thread for months, wondering what you guys have been yammering on about. I am so in love with my 4K/HDR projector, I couldn't imagine my theater getting better.
Then last night, my installer hooked up four little (well, 6.5 inch...

) round speakers in my ceiling.
O.M.G. Watched a scene from John Wick 2, a scene from Baby Driver, and my daughter's favorite scene in the entire library, the Groundhog driving scene in Groudhog Day. (Not too bad for a quadruped!)
I get it now. Please issue me my torch and pitchfork so that I might join the brigade marching in the streets whenever we get a title without Atmos. The difference in the experience is unbelievable, immeasurable, unthinkable.
People, if you don't currently have Atmos speakers... get them. Now.
