whathifi verdict:
The XIO is supremely easy to listen to, creating an impressively wide sense of space for a soundbar while maintaining balance and expressiveness.
With a comprehensive app and plenty of streaming connectivity, it also works as an excellent sound system for music alone.
KEF says that it wants the soundbar to effectively act as a hi-fi package wrapped up in one product, and it has achieved that. Put simply, it is one of the best soundbars we have heard.
