iFi Zen Air Phonochat_bubble_outlineFrom real comments

It sounds noticeably better than built-in preamps. Multiple owners comparing it directly to a turntable's onboard preamp heard clearer highs, better separation, and a wider soundstage, even through modest gear like phone speakers or earbuds. Several called the difference subtle but real, and simple setups with the AT-LP60X or LP70X reportedly benefited. One reviewer who bought based on this comparison said it's right up their alley for good sound at a good price.

It's remarkably quiet, especially with tube amps. Several users running the unit through tube amplifiers (Eico ST-70) with arm setups described it as 'dead quiet' or 'magnificent,' with the 3-D imaging staying intact. One person used a blind test to compare vocal and instrument placement and preferred it to a Schiit Mani 2 for its near-zero noise floor, calling the experience wondrous and its 40dB gain sufficient even where hum was previously an issue.

Its plastic looks and power setup split opinion. Several buyers flagged the plastic casing and fingerprint-attracting front panel as letdowns for an otherwise appealing unit, and a couple called its shape and '1950s'/Jetsons-style design odd or ugly enough to give them pause. On the power side, one user noted it needs an exact 5V source with no matched brick included, unlike the standard Zen Phono, making them wary of pairing it with a cheap supply.
