Sonos Arc Ultra
KEF XIO
The KEF XIO is a much more expensive soundbar than the Sonos Arc Ultra, and for most people, that extra outlay probably isn't worth it. The KEF's physical design is certainly more arresting, with a stylish, industrial-like look, making a welcome change from the all-black-bars that most soundbars take. But performance-wise, the Sonos offers a more accurate frequency response and wider-feeling soundstage. That said, the KEF does make Atmos content seem a bit more immersive, although since both bars lack dedicated satellites, there's only so much immersion you can expect from either setup. The KEF does have Optical built in, while the Sonos needs an adapter to support Optical, which uses up an eARC port. But for most people who just want a good-sounding bar, the Sonos is a better value.
