The best smart speakers for music fans

If you're a music fan, the first wave of smart speakers was probably a disappointment. While Alexa and Google Assistant have definitively proven they have a place in the home, the first Echo and Google Home devices were unimpressive when it came to actually playing music. They did the job in a pinch, and being able to command Spotify with your voice is a killer feature, but many longed for better-quality audio. Fortunately, that call has been answered. In the past six months, Sonos, Google and Apple have all released music-first speakers with voice assistants built in. If you value audio quality above all else (and have about $400 to spend), what's the right smart speaker for you?
