Our Verdict
Sonos Arc with Sub + One SL Speakers
Vizio M Series M51a-H6
The Sonos Arc with Sub + One SL Speakers is better than the Vizio M Series M51a-H6 for most uses. The Sonos is better built, with better soundstage, surround, and Atmos performances. Unlike the Vizio, it has room correction and built-in voice assistant support. Some listeners may prefer the Vizio's more neutral sound profile out-of-the-box. The Vizio also has a Full HDMI In port that supports high-quality passthrough, unlike the Sonos.
