Amazon Echo (4th Gen) review: The more things change, the more they stay the same

The fourth generation of Amazon's Echo smart speaker marks a radical departure in industrial design, ditching the familiar columnar form factor of previous iterations for something that looks for all the world like a child's bowling ball. Two things haven't changed: The Echo (and Alexa) remain our favorite tools for smart home control, and the company still trails Sonos in terms of building smart speakers that sound great. The recent introduction of the Nest Audio leaves Amazon in third place behind Google in terms of audio performance (don't forget the powerful Google Home Max). Amazon continues to make strides in terms of audio quality, and the fourth-gen Echo sounds very good, especially if you like your tunes leavened with bass. But in a three-way comparison with the Nest Audio and the Sonos One (which, I should note, costs twice as much as either of its competitors), the Echo comes up just a wee bit short, as I'll discuss a bit later.
