Who wins on what

Ranked by what users actually praise

Overall Impression

Sound quality wins over nearly everyone who tries it. Reviewers and owners repeatedly describe the Zen One Signature as warm, natural, and highly resolving without sounding sterile or analytical. Several call it a 'giant killer' that beats more expensive DACs, integrated amp DACs, and even other iFi models like the Neo. It's praised as an easy, fatigue-free listen for hours, taming bright tweeters and outperforming DACs in equipment costing far more.

The shared coaxial/optical input is the DAC's most consistent flaw. Multiple owners independently flagged that the coaxial and optical SPDIF inputs share circuitry, meaning switching between a CD player and a streamer requires powering one off or resetting the unit. Users find this odd for a DAC marketed as 'the only DAC you'll ever need,' especially since much cheaper DACs handle both inputs simultaneously without issue.

Control and reliability niggles crop up for some buyers. A handful of owners experienced background noise or hiss through their amplifier, sudden unexplained volume jumps, or frustration that volume can't be adjusted from a phone app or remote, unlike competing streamers. These issues led at least two commenters to return their units and switch to alternatives like the Cambridge 200M or Bluesound Node X.
