What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Samsung HW-Q990D
One whitelisted tester source survived verification: Engadget, a genuine hands-on review of the exact model (HW-Q990D, correct 'D' suffix). Both quoted sentences were re-confirmed verbatim on the page. RTINGS and TechRadar candidate pages returned no usable body text and were excluded, so this consensus rests on a single source. Engadget praises boomy, immersive all-in-one 11.1.4 Atmos sound with new HDMI 2.1 conveniences, but flags only a minor generational upgrade over the Q990C at a $2,000 list price. (1 sourced review, 1 lab-tested.)
Praised: Boomy, immersive all-in-one 11.1.4 Atmos sound with modern conveniences (HDMI 2.1).
Flagged: Only a small upgrade over the previous Q990C model at a high $2,000 list price.
