Quick Read

iFi ZEN DAC 3

The ZEN DAC 3 continues the line that made desktop hi-fi a $229 purchase: a third-generation compact DAC/amp decoding up to DSD512, outputting 390mW, now with USB-C and the improved XBass+ analog bass correction. Headfonics' verdict tracks the series' reputation: a great-sounding all-in-one that doesn't break the bank, with robust build and elegant design, and XBass+ a genuine improvement over the old TrueBass. The known limits are unchanged: 390mW won't move demanding headphones, the house tuning leans warm-smooth rather than reference-flat, and balanced output requires stepping up iFi's own line.

Questyle M18i

The M18i is Questyle's current flagship dongle, pairing an ESS Sabre DAC with the company's patented Current Mode Amplification in a fully balanced design, and, unusually for the class, adding wireless capability on top of USB duty. Approved coverage positions it as the refinement-first choice among premium dongles: Questyle's current-mode topology keeps distortion vanishingly low and transients clean, continuing the lineage that made the M15 a class reference. The recurring tradeoffs for the line remain: premium pricing, moderate output power relative to power-focused rivals, and a presentation that prioritizes precision and cleanliness over warmth or coloration.

Strengths

  • Warm, engaging all-in-one sound with genuinely useful XBass+ correction
  • Robust, elegant build that outclasses the $229 price
  • Modernized with USB-C and DSD512 support

Weaknesses

  • 390mW is IEM-and-easy-headphone territory only
  • Warm-smooth tilt is a flavor, not a reference
  • Power users outgrow it faster than pricier iFi siblings

Strengths

  • Patented Current Mode Amplification delivers ultra-clean, precise transients
  • Fully balanced flagship design with wireless flexibility uncommon in dongles
  • Continues Questyle's reputation for class-reference refinement

Weaknesses

  • Premium price for the dongle category
  • Output power trails power-first rivals like desktop-mode dongles
  • Clean, precise character offers little for warmth seekers
