Short answer: the Amazon Echo Studio 2nd Gen. It ranks #2 of 10 powered desktop speakers by sound quality at $219.99; the Denon Home 150 ranks #4 and costs $249, which makes this an easy call rather than a real tradeoff.
The case for the Amazon Echo Studio 2nd Gen: SoundGuys called it the best-sounding Amazon speaker they have tested, scoring it 7.8 of 10. 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 mono smart speaker with a 1-inch tweeter and a 3.5-inch mid/bass driver that Tom’s Guide called great-sounding, with bass performance that belies its size. 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 ranks higher for sound quality than the Denon Home 150 and costs less, so there is no real case for the other one.

The Two Speakers In Full
Amazon Echo Studio 2nd Gen: $219.99 each Amazon eBay
Pros: SoundGuys called it the best-sounding Amazon speaker they have tested, scoring it 7.8 of 10. A 3.75-inch high-excursion woofer and three 2.25-inch full-range drivers fire left, right and upward, giving a real sense of width and instrument separation from a single enclosure, with vocals sitting forward and clean cymbals even at moderate volume. It supports Dolby Atmos and spatial audio on compatible content, stays distortion-free up to about 70% volume, and includes a built-in Zigbee, Matter and Thread smart home hub plus a 3-band EQ with a Dolby Virtualizer toggle.
Cons: 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. There are no wired audio inputs of any kind and no battery, so it must stay plugged in, and Bluetooth is limited to the SBC codec. Voice recognition wasn’t perfectly reliable in testing, occasionally playing the wrong track for a specific artist-title request.

Denon Home 150: $249 each Amazon eBay
Pros: A compact mono smart speaker with a 1-inch tweeter and a 3.5-inch mid/bass driver that Tom’s Guide called great-sounding, with bass performance that belies its size. The touch controls light up via a proximity sensor for quick-select presets, Wi-Fi setup through the HEOS app is straightforward, and Amazon Alexa is built directly into the speaker rather than relayed from another device. A second Home 150 can be paired for stereo.
Cons: 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. It’s a single small driver plus tweeter, so it won’t fill a large room or go especially deep without pairing a Denon subwoofer.
