## What reviewers say

**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.)

**Sony Bravia Theatre Bar 9** — Only one whitelisted tester (What Hi-Fi) yielded a verifiable review body for this exact model (Sony Bravia Theatre Bar 9 / HT-A9000). What Hi-Fi rates it a five-star Award winner: a clear upgrade on the three-time Award-winning HT-A7000, with superb clarity, detail and dynamics, and the most convincing Atmos it has heard from a standalone soundbar. Trade-offs are a slightly clinical voicing with less warmth than the predecessor, occasionally over-pronounced deep bass at high volume, no display, and only one HDMI input. No lab measurements were published. (1 sourced review.)
