Samsung Q Series HW-Q900A 7.1.2 Channel True Dolby Atmos Soundbar
Cheaper than Samsung Promotion.
Got the same last week from JB using Coles Ultimate Gift Cards. Works perfectly for me with Apple TV 4K and Sony 9300E. Output both Dolby Atmos and Dolby Vision.
If you have a TV that supports eARC, could be even better.
This soundbar has 1 x eARC/ARC output (HDMI 2.1) and 2 x HDMI 2.0 Inputs
