In this article, I review the iFi ZEN DAC 3. This 3rd generation of the widely acclaimed Zen DAC ups the ante with support for higher sample rates and Improved DC offset and USB-C input overvoltage protection. It’s priced at $229.

Design & Features
The familiar lines and curves of the iFi ZEN DAC 3’s chassis remain unchanged from the original ZEN DAC and ZEN DAC V2. Thankfully, this latest version boasts the same thick aluminium casing seen on the aforementioned models and not the thermoplastic polymer (plastic) used on the iFi ZEN Air DAC.
The front panel layout is similar again but now looks more premium thanks to a two-tone design accompanied by the ‘Sunlit Bronze’ coloured buttons and volume knob. It’s a somewhat divisive aesthetic but I appreciate the departure from the countless ‘black box’ designs flooding the market.
We find the same features as the previous models – namely the Power Match, which is essentially a gain switch that’s useful for more demanding headphones and speakers. Then there’s the xBass+ which does exactly what you’d expect – it’s an analogue bass boost that adds power and body to the low frequencies. This is especially useful for brighter headphones or ones that lack the desired bass response.
6.35mm and 4.4mm headphone outputs are located on the front panel. The headphone power output level remains unchanged from previous models: 210mW @ 32Ω from the 6.35mm and 390mW @ 64Ω from the 4.4mm balanced output.
There’s a 4.4mm balanced output on the rear panel and single-ended RCA outputs. The line out level can be either Variable or Fixed and is set via a switch on the rear panel. It should be noted that the ZEN DAC 3 simultaneously outputs to all line outs and headphone outputs at the same time so you might need to unplug or switch cables when swapping between them.
The unit is powered by a single USB-C cable, which helps reduce wire clutter and saves space. For a cleaner, more refined sound, you have the option to use an external 5V power supply (not included), though you’ll need to use one you already have or buy it separately. There’s no power ON/OFF switch so the unit is in an always-on state. Thankfully, this isn’t a problem because it never gets hot or even warm to the touch. However, if you prefer not to leave devices powered on, you’ll need to unplug the USB cable manually.
Internally, ZEN DAC 3 features iFi’s usual Burr-Brown bit-perfect DAC chip. It has been upgraded to now support up to 768kHz and DSD512. Furthermore, a significant reduction in DC offset has been achieved to minimize clicks when adjusting settings.
Sound
I tested the iFi ZEN DAC 3 with some of my usual headphones and IEMs including the Sennheiser HD650, I/O Audio Volare and Spiral Ear Se6 Nebula. The DAC retains its smooth and slightly warm tonality from the previous models. It’s more colourful than some of the ultra-neutral DACs released recently, resulting in a musical and engaging presentation.
It’s dynamic but slightly warm, with rich vocals and a full-bodied presentation. I find this kind of character immersive and compelling and can easily get lost in the music. But the best part? It’s colourful yet technically impressive, even more so than older models, thanks to iFi Audio’s continual improvements in internal circuitry. It finds the perfect balance between expressiveness and precision.
Listening to Rossini’s Le siége de Corinthe with the Sennheiser HD650 (high gain), the ZEN DAC 3 handles the composition with finesse. It showcases impressive dynamics and layering, contrasting the swelling horns at centre stage with the subtle rattle of the snare off to the far right. It’s easy to picture the orchestra spread across a wide stage and to pinpoint instrument locations with precision. The strings strike the right balance of vibrancy and body, with enough resonance to feel rich and full, yet maintain a lively, articulate presence.
Next up was the haunting Challenger Part 1 by We Lost the Sea. For this track, I chose to pair the iFi ZEN DAC 3 with the I/O Audio Volare IEMs (low gain). Super detailed sound with excellent sub-bass extension and punchy mid-bass. I tried this with xBass+ turned on and it was a lot of fun but ultimately, I preferred the cleaner and more nuanced character when it was turned off. When things heat up towards the end of the song, the electric guitars sound gritty and texture yet still distinctly separated from the voice recordings. The left-to-right stereo separation is excellent and despite its musical character, the ZEN DAC 3 doesn’t miss any of the nuances or micro-details in the track. During the crescendo, the iFi and IEMs hold everything together with ease, both handling the complexities and maintaining instrument separation. I even discovered some intricacies that I hadn’t heard previously with other setups, which is always a treat.
Finally, it was time to connect the Spiral Ear Se6 Nebula. These IEMs are ultra-resolving and very sensitive, so they’re great for testing DACs. Firing up Katie Melua’s A Love Like That, the ZEN DAC 3’s midrange clarity and vocal presentation shine. Melua’s delicate vocals are reproduced with exceptional detail, showcasing the DACs ability to capture the nuances of her voice. The acoustic guitar accompaniment is rendered with warmth and realism, creating a beautifully intimate presentation.
Comparisons
Topping DX3 Pro+ ($199)
The Topping DX3 Pro+ (review here) features an ES9038Q2M DAC chip and Bluetooth with LDAC and aptX HD support. It also supports dual coaxial and optical inputs. However, the iFi ZEN DAC 3 has a 4.4mm headphone output, making it more versatile when it comes to headphones.
The DX3 Pro+ has good build quality but it pales compared to the ZEN DAC 3’s stylish and robust aluminium frame. The Topping has a digital volume control (and a remote) while the iFi boasts an analogue volume control. One more thing worth noting is the DX3 Pro+ has a relatively massive 1800mW x2 @32Ω output power from its 3.5mm headphone out whereas the ZEN DAC 3 only manages a meager 390mW from its balanced output.
The DX3 Pro+’s sound signature is more neutral and transparent whereas the ZEN DAC 3 is more musical or coloured. Which presentation is better will depend on your personal preferences, as will the I/O options and features.
SMSL RAW-MDA 1 ($246)
The SMSL RAW-MDA 1 (review here) features dual ES9039Q2M DAC chips, Hi-Res Bluetooth connectivity and a multitude of input and output options. Feature-wise, the SMSL handily beats the iFi ZEN DAC 3. But it’s important to keep in mind that some users want a minimal setup and in that case, the iFi will surely appeal.
The RAW-MDA 1 delivers an impressive 1700mW of output power, making it ideal for driving power-hungry headphones. It’s also a better choice for those seeking neutrality, because of its uncoloured and neutral sound signature. The SMSL is a great choice for those seeking a more detailed and analytical presentation whereas the ZEN DAC 3 will appeal to people looking for a simpler setup and a warmer tonality.
Verdict
The iFi ZEN DAC 3 continues the ZEN DAC legacy of straightforward and uncomplicated desktop DACs with its musical yet technically proficient character. I found it an especially good partner for leaner or drier headphones/IEMs, where its subtle touch of colour really brought them to life. In addition, the xBass+ is a feature that many listeners will appreciate, whether they be bassheads or those who crave more body in their music.
If you already own the V2, I’d hesitate to recommend this as an upgrade, unless you feel like you need the 32-bit/768kHz support. Otherwise, it’s impossible not to appreciate the value of the ZEN DAC 3. Recommended!
