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 350 ranks #6 and costs $749, 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 350: RTINGS measured it getting pretty loud with lossless streaming support from platforms like Roon, Tidal and Spotify, and found its Alexa voice assistant support outstanding, with hands-free far-field mics built directly into the speaker. The tradeoff: RTINGS measured a slightly boomy sound profile out of the box and disappointing directivity, so the sound changes noticeably off to the side of the cabinet, plus compression artifacts as it nears max volume.
Buy the Amazon Echo Studio 2nd Gen. It ranks higher for sound quality than the Denon Home 350 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 350: $749 each Amazon eBay
Pros: RTINGS measured it getting pretty loud with lossless streaming support from platforms like Roon, Tidal and Spotify, and found its Alexa voice assistant support outstanding, with hands-free far-field mics built directly into the speaker. Two 0.75-inch tweeters, two 2-inch midrange drivers and two 6.5-inch woofers are each driven by their own Class D amp, six in total, and the companion app adds bass and treble sliders for room-to-room tuning.
Cons: RTINGS measured a slightly boomy sound profile out of the box and disappointing directivity, so the sound changes noticeably off to the side of the cabinet, plus compression artifacts as it nears max volume. Bluetooth latency measured extremely high on both iOS and Android, making it a poor match for watching video over Bluetooth, and there’s no battery, so it’s an indoor, mains-powered speaker only.
