Short answer: the Bowers & Wilkins Zeppelin Pro. It ranks #1 of 10 powered desktop speakers by sound quality, rated 4.4/5, at $899. The Sonos Era 300 ranks #6, rated 4.0/5, at $499, $400 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Zeppelin Pro is the better stereo speaker. A 150mm woofer, two 90mm midranges and two titanium tweeters on 240W give wide stereo and deep bass for one box, with aptX Adaptive, AirPlay and Dynamic EQ. Its customizable light is a nice touch. It has no room correction, no battery and no water resistance.
The Era 300 is built for spatial audio and the Sonos ecosystem. Side and upward-firing tweeters add Dolby Atmos height, Trueplay room correction tunes it to the room, and it pairs with Sonos soundbars for home theater. Out of the box it leans bass-heavy enough to cover vocals until Trueplay corrects it, and it compresses at full volume.
Buy the Bowers & Wilkins Zeppelin Pro. It is rated higher for sound quality, and the $400 saving on the Sonos Era 300 is not enough to make up the difference.
