What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Sonos Arc Ultra
Verified two whitelisted hands-on reviews (Engadget, SoundGuys); all six quotes were re-confirmed verbatim on their pages and both cover the exact Sonos Arc Ultra model. Neither source published lab-measured values with units, so no measured-value cross-check was possible. Both praise the sound and bass performance while flagging the steep $999 price and the cost of expanding to a full surround setup. A previously listed 'sleek low-profile design' praise point was dropped as unsupported by any verified quote. (2 sourced reviews, 2 lab-tested.)
Praised: Genuine sound and bass upgrade over the original Arc, with clean spatial detail and dialogue that stays clear.
Flagged: Expensive at $999, and expanding the system (sub/rears) gets pricey fast; A single bar still does not fully replicate a true rear-channel surround setup.
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.
