Short answer: the Amazon Echo Studio 2nd Gen. It ranks #2 of 15 powered desktop speakers by sound quality (rated 3.8/5) at $219.99 and is still sold new; the Denon Home 150 ranks #6 (rated 3.5/5) and is discontinued, so it is only an option used. The Denon Home 150’s replacement, the Denon Home 200, is rated 3.6/5 at $399.
The case for the Amazon Echo Studio 2nd Gen: A great sounding Amazon smart speaker, with wide sound from one box, Dolby Atmos and a built in smart home hub. It has an adjustable EQ, which the Denon Home 150 lacks. The tradeoff: SoundGuys still marked it down on Value (4.0 of 10) given the $219.99 list price, and it is explicitly not true left-right stereo from one cabinet, so a stereo pair is needed for real width in a larger room.
The case for the Denon Home 150: A compact smart speaker with built in Alexa, easy HEOS setup and stereo pairing with a second unit. It keeps a wired aux input, which the Amazon Echo Studio 2nd Gen lacks. The tradeoff: Tom’s Guide’s own complaints are that it costs more than the Sonos One and has no automatic room tuning to correct for placement.
Buy the Amazon Echo Studio 2nd Gen. It is rated higher for sound quality; the Denon Home 150 is no longer sold new.
