About the iFi Audio ZEN DAC

Solidly built DAC/amp that fits into small spaces

My home office is not exactly spacious or private — but I make it work. And thanks to the iFi Audio ZEN DAC, I'm still able to enjoy premium sound through a nice set of headphones. This compact yet heavy-duty device connects between your computer and headphones for two reasons: to bypass your computer's lousy soundcard, and to provide your headphones with enough power to make them sound their best.

My home office is a little cramped, but the iFi ZEN DAC took up little space and drove premium headphones of all shapes and sizes.

Solidly built DAC/amp that fits into small spaces

My home office is not exactly spacious or private — but I make it work. And thanks to the iFi Audio ZEN DAC, I'm still able to enjoy premium sound through a nice set of headphones. This compact yet heavy-duty device connects between your computer and headphones for two reasons: to bypass your computer's lousy soundcard, and to provide your headphones with enough power to make them sound their best.

And you have to love that old-school volume dial sitting right in the center of the front panel — it's the first thing you see! It was really satisfying to adjust the volume that way. I got that nice, tactile feel you just don't get from clicking a mouse to turn the volume up and down.   

Connects to your computer and comes to life

The ZEN DAC has sort of a grab-and-go design, but I can't call it portable. There is no built-in battery. But it will draw power from your computer, so you don't have to connect to an AC outlet. In fact, the AC adapter is sold separately. 

I connected the ZEN DAC to my work laptop using the included USB cable (with a Type A USB male on one end and Type A USB female on other end). I auditioned several pairs of headphones, including some superhigh-end models, and the ZEN DAC was powerful enough to drive them all. This unit also doubles as a stereo preamplifier, with RCA outputs for connecting directly to an amplifier. 

Makes all your digital music sound better

The ZEN DAC features a high-grade Burr-Brown DAC chip that can squeeze out more musical detail from Spotify®, Apple Music®, YouTube, and other digital audio sources. This DAC will decode high-resolution music files up to 32-bit/384Hz resolution, and DSD files up to 11.2 MHz. So I primarily streamed lossless high-res tracks via Qobuz. (It also offers full MQA support if you use Tidal Masters.) 

Listening impressions with a few different headphones

I made one really clutch move back in mid-March. On my way out of the office, I grabbed the Audio-Technica ATH-AWKT over-ear headphones. These premium audiophile cans have large, handmade earcups made of rare Japanese kokutan striped ebony wood.

I've been driving them with the ZEN DAC. It is a super-nice combo that delivers an enormous soundstage with incredible depth and detail. And iFi's “Truebass” boost button provides some extra oomph that really rounds the sound out. On "Grandma's Hands" by Bill Withers, his moving, familiar opening riff and vocals seemed to leap out as the wood earcups lent a realistic, refreshing timbre.

Another combo I really enjoyed was the ZEN DAC and the open-back Audeze LCD-1 planar magnetic heaphones. These two together give you a lot of bang for your buck. They complement each other well, and I would put them up there with some headphone/DAC/amp systems that cost thousands of dollars.

S-balanced headphone amp

On the front panel, there is a 1/4" stereo headphone jack along with a balanced 4.4mm headphone output. The latter is the new industry standard balanced connection that helps cuts down on signal noise and distortion. A growing list of headphones from multiple brands use it.

Either way you connect takes advantage of what iFi calls "S-balanced" headphone amp technology. Their dual-mono circuitry keeps the left and right audio channels separate for as long as possible to avoid cross-talk and distortion.

Product Research


Overview: The ZEN DAC is a stylish, compact desktop DAC (digital-to-analog converter) and headphone amplifier. Like it's cousin, the ZEN Blue, ZEN DAC is housed in a blue aluminum enclosure with brushed aluminum front and rear panels. It has a USB 3.0 Type B input, with RCA stereo and 4.4mm Pentaconn line outputs on the back, and 3.5mm unbalanced and 4.4mm balanced headphone jacks on the front. USB (3.0) and RCA cables are included.

Digital-to-Analog Conversion: ZEN DAC plays Hi-Res audio in the original format, including DSD (up to 256 MHz), DXD (up to 384 kHz), and PCM (up to 384 kHz). You can also listen to MQA (Master Quality Authenticated) audio. It uses a Burr-Brown "True Native" chipset which sends PCM and DSD signals down separate pathways so each format remains "bit-perfect" all the way to its conversion to analog. The ZEN DAC is compatible with the following audio formats:

  • DSD: 256, 128, 64 MHz
  • DXD: 384, 352.8 kHz
  • PCM: 384, 352.8, 192, 176.4, 96, 88.2, 48, 44.1 kHz
  • MQA

MQA (Master Quality Authenticated): The ZEN DAC includes MQA rendering technology, which enables you to play back MQA files and stream MQA audio from sites such as Tidal Masters. MQA delivers the sound of the original master recording, so you'll hear the music exactly the way the artist intended.

LED Indicator: The ZEN DAC's analog volume control is backlit by an LED that indicates the sampling frequency received from the source. The LED color scheme is as follows:

  • Green: PCM 44.1 / 48 / 88 / 96 kHz
  • Yellow: PCM 176 / 192 / 353 / 384 kHz
  • Cyan: DSD 64 / DSD 128
  • Blue: DSD 256
  • Magenta: MQA

Headphone Amplifier: The iFi ZEN DAC's headphone amplifier can drive most headphones and in-ear monitors rated at 16 to 600 ohms. The balanced 4.4mm Pentaconn headphone output uses inverse positive/negative electrical paths to deliver equal and opposite audio signals to each side of the headphone driver voice coil. The balanced output offers double the voltage output for driving bigger and more difficult-to-drive headphones. It also produces reduced THD distortion and crosstalk, compared to unbalanced, single-ended outputs. The ZEN DAC also features a single-ended 1/4" (6.3mm) unbalanced headphone output with iFi's S-Balanced circuit topography, which is specially suited for IEMs (in-ear monitors). S-Balanced features a dedicated negative wire for each channel, and supports both TRS and TRRS headphones. For headphones with a 3.5mm plug, you can use the included 3.5mm-to-1/4" plug adapter.

PowerMatch: The headphone output is equipped with iFi's PowerMatch technology. You can turn PowerMatch on or off as needed to match the level of the drive to the load presented by the headphones. When switched on, PowerMatch adjusts the input sensitivity and signal strength, which works best for less sensitive large headphones. Leaving PowerMatch off works best for the more sensitive IEMs.

TrueBass: The iFi ZEN DAC features iFi's switchable analog TrueBass circuitry that adds back the lost bass response to give you a more accurate reproduction of the original music. TrueBass' High Setting works well for many IEMs and open-back headphone designs, while the Low Setting should be adequate for most closed-back over-ear headphones.

USB Input: The ZEN DAC has a Type B USB 3.0 input that connects to your computer audio source. The input supports the "SuperSpeed" USB 3.0 standard, and is also compatible with USB 2.0. It also supplies power to the unit.

Analog Outputs: The rear panel offers both balanced and unbalanced analog outputs. The balanced output has a 4.4mm Pentaconn jack, which can be used with 4.4mm-to-XLR or other balanced interconnects. This output can be used for an active speaker or amplifier. The unbalanced output is an RCA stereo pair.

Variable/Fixed Output: ZEN DAC offers switchable variable or fixed line outputs. If you wish to use the unit's analog rotary volume control on the front panel, you should set the Variable-Fixed switch to the "Variable" position. This is recommended for connecting ZEN DAC to a power amplifier or active speakers. If you are connecting ZEN DAC to a receiver, integrated amplifier, or other device with a volume control, setting the switch to "Fixed" will provide the best results. This switch does not affect the front panel headphone outputs.

5.0V DC Power Input: A 5-volt DC input is provided for a DC power supply (not supplied). ZEN DAC can be powered by either a DC power supply or via the USB 3.0 input.

How do I connect this to an iphone?
[ R  Aug 26, 2021 ]
3 answers
Are you using both the ZenDac and ZenCan? Or just the one Zen Dac/Amp as a combo unit? Sorry it's hard to explain because they have multiple units old and new. You hooking up to a pc or laptop or stand alone?
[ DAVID  Aug 26, 2021 ]
The blue cable that came with the dac is a USB input "A/B" cable and is the only way to for the unit to receive an audio signal. The smaller connector end is the USB B connector which plugs into the back of the dac, the wider end of the cable is the USB A connector which connects to your source - in your case the iphone. However, the iphone does not have a USB A port and you will need to get a cable that has a USB A on one side, and I assume a lightening connector on the other. I'm more familiar with Android as they use inexpensive OTG cables for this. Suggest checking with Apple for the proper cable. Once connected you can listen to headphones plugged into the headphone jack on the front (set the slider switch on the back to variable) and use the dac's volume control, or you can use the iphone as a music source for your hifi (set the slider switch on the back to fixed) by using standard RCA cables from the analogue output on the back of the dac to any of the line inputs of your amp/receiver. Either way the sound quality of this DAC is excellent. Good luck!
[ Charles  Aug 26, 2021 ]
You MUST have the USB-to-Lightning adapter. Without this, the iPhone will not send out the digital signal. see ifi website
[ A  Aug 26, 2021 ]
Will this work to stream 320 AAC?

Is it running without power cord?
[ Steven  May 20, 2020 ]
5 answers
Yes this unit will function without a power brick. Although I personally found that even adding a cheapo had slight benefits to the sound. It's difficult to describe succinctly, but I would just have to call it.. "better." And by cheapo, I'm talkin about like.. a 16usd brick. I have heard others say that the ifi one sounds better, but I have not yet tested this.
[ Warren  May 22, 2020 ]
Yes. Power is provided via usb cable
[ Bernardo  May 21, 2020 ]
it can. It uses USB power or power cord.
[ joshua  May 20, 2020 ]
Yes, will run of USB bus power, that is how I have mine setup.
[ Mathew  May 20, 2020 ]
Yes it uses the usb from your pc to power the device
[ tlaren4  May 20, 2020 ]
Does the volume nob only work for headphones or does work on the rca output as well?
[ Bernardo  May 04, 2020 ]
4 answers
The volume pot/knob will in fact throttle the 6.4mm or 4.4mm headphone sockets like normal with any other amp. On the back of the unit there is a little switch that can be slid from left to right to allow you to not only use the pot's throw to control the output volume over the 4.4mm and the RCAs. It will also allow you to use the high or low gain stages, and also make use of the unit's truebass function. I find it pairs quite... quite well with the Erish amp from Geshelli Labs over balanced and the Koss ESP95X over RCA. Quite fun indeed.
[ Warren  May 22, 2020 ]
It works on both.
[ joshua  May 20, 2020 ]
The volume knob works for the rca output as well if the switch on the back is set to variable.
[ Tyler  May 04, 2020 ]
Yes it works for the RCA output as well. I required volume control on output as the last DAC I purchased, Cambridge DacMagic 100, overloaded my powered speakers. This works great at about "1:00" on the dial for my Kanto YU6 speakers. Anything past "3:00" distorts on my Kantos. I recommend anyone with powered speakers to only purchase a DAC with output control.
