iFi Audio Zen DAC 3 noir

The Zen DAC 3 is the third generation of the compact digital-to-analog converter developed by iFi Audio. This model incorporates the experience gained from previous versions and uses selected audiophile components to ensure seamless connection between digital sources and an audio system.

A concentration of technology in a refined casing

The Zen DAC 3 abandons the monochrome sobriety of its predecessors in favor of a sophisticated two-tone aesthetic. Its thick aluminum chassis now sports a bluish “gunmetal” finish on its lower section, while the upper half of the front panel features a dark gray leather-like texture dotted with points. The Power Match and XBass+ buttons, as well as the central volume knob, are adorned in a golden bronze hue (“Sunlit Bronze”) that lends the unit a distinctly premium look.

This visual evolution in no way compromises the legendary robustness of the Zen series. The compact dimensions (158 × 115 × 35 mm) and modest weight (456 g) allow for seamless integration on any desk, while preserving the distinctive curved shape that defines the range’s identity. The all-metal construction ensures exemplary durability and natural heat dissipation — the device remains perfectly cool even after hours of intensive use.

Internal architecture: the pursuit of sonic purity

At the heart of the Zen DAC 3 beats a Burr-Brown DAC customized by iFi Audio, the fruit of decades of expertise in digital conversion. This chip, stemming from the historic collaboration between Burr-Brown and Texas Instruments, benefits from a four-channel True Native architecture that preserves signal integrity, whether PCM or DSD. Each format follows its own processing path, ensuring “bit-perfect” conversion all the way to the analog output.

The latest-generation 16-core XMOS processor (2000 MIPS with 512 KB of internal memory) orchestrates decoding with minimal latency. This processing power allows the Zen DAC 3 to handle the most demanding formats with ease: PCM up to 768 kHz at 32-bit, native DSD512, and DXD up to 768 kHz. The GMT (Global Master Timing) clock, improved for this third generation, drastically reduces jitter, those micro timing variations that can affect playback accuracy.

Technical features and innovations

The move to USB-C marks an important step in the evolution of the Zen DAC. This modern interface not only provides better bandwidth for high-resolution audio signals but also integrated surge protection — a first at this price point. The USB-C port handles both power and data transfer simultaneously, greatly simplifying cabling.

The rear panel offers comprehensive connectivity with unbalanced RCA line outputs and a balanced 4.4 mm Pentaconn output. A switch lets you toggle between fixed mode (for connection to an amplifier) and variable mode (for active speakers), turning the Zen DAC 3 into a quality preamplifier. This flexibility goes well beyond that of competing converters like the AudioQuest DragonFly Cobalt, which is limited to a single headphone output.

Headphone amplification: power and finesse

The integrated amplification stage delivers up to 390 mW into 64 ohms in balanced mode (4.4 mm output) and 210 mW into 32 ohms in unbalanced mode (6.35 mm output). These figures may seem modest on paper, but the remarkably low output impedance (≤ 1 Ω) ensures optimal control across a wide range of headphones, from sensitive in-ears to 600-ohm over-ear models.

The PowerMatch function, inherited from previous generations, adjusts gain for more demanding headphones. This analog approach avoids digital artifacts while preserving signal dynamics. The 109 dB signal-to-noise ratio and total harmonic distortion below 0.005% in balanced mode attest to a meticulous design where each stage has been optimized to minimize noise and coloration.

XBass+: iFi’s sonic signature reinvented

The shift from TrueBass to XBass+ is one of the major improvements in this third generation. This purely analog circuit restores low frequencies often attenuated by open-back headphones, without resorting to digital signal processing. The result? A remarkably natural bass extension that enriches listening without distorting tonal balance.

The XBass+ implementation in the Zen DAC 3 is more pronounced than on other iFi products like the Gryphon or the Hip-DAC. This generosity can be appealing for party listening or recordings lacking body, though some users may prefer to disable it for critical sessions. The beauty lies in the instant choice available via a simple front-panel button.

Sound performance: between musicality and precision

The Zen DAC 3 perpetuates iFi Audio’s sonic philosophy: a slightly warm presentation that prioritizes listening pleasure without sacrificing resolution. This subtle coloration, characteristic of Burr-Brown converters, manifests as an especially expressive midrange where female vocals gain emotional presence and acoustic guitars gain texture.

The soundstage impresses with its spatial organization. While intimate in absolute width and depth, it offers precise instrument separation and remarkably stable stereo imaging. Ambient microphones are clearly locatable, and the natural reverberations of concert halls are faithfully reproduced. This ability to create a coherent sonic bubble turns headphone listening into a truly immersive experience.

Broad compatibility and versatile use

The Zen DAC 3 excels with an impressive variety of transducers. Open-back headphones like the Sennheiser HD650 or the HiFiMAN Edition XS reveal the converter’s full harmonic richness, while sensitive in-ears benefit from the particularly low noise floor. Even the Beyerdynamic DT770 Pro 250-ohm, known to be hard to drive, sound authoritative and controlled.

The absence of a power on/off switch may initially be surprising, but this “always-on” design has advantages: instant availability, no power-on transients, and negligible power consumption (0.5 W at idle). For purists wishing to further optimize performance, adding an external iFi iPower2 power supply (sold separately) allows complete decoupling of power from the USB signal, further reducing the already exemplary background noise.
