Our Verdict

Sonos Arc

Sony HT-A9

The Sonos Arc is better than the Sony HT-A9. These setups have very different designs, as the Sonos is a long standalone bar while the Sony is a small box with four satellites. The Sonos reproduces a slightly more extended low-bass and has a better center channel performance. However, the Sony has a better soundstage. You can also upgrade both of these setups with subwoofers.
