Product Information

Smartly dressed in petrol blue with a touch of copper, the go-anywhere hip-dac is designed to slip discreetly into a pocket and offers an extensive hi-res specification that belies its eminently affordable $149 price tag. The hip-dac replaces the inferior DAC (Digital-to-Analogue Converter) and amp circuitry in smartphones, tablets, PCs, and Macs to vastly improve headphone sound.

Its design and performance set it apart from other DAC/headphone amps in its class – connect your playback device via USB, plug in your favorite corded headphones or in-ear monitors and the hip-dac delivers a sound brimming with bold dynamism and fluid refinement, effortlessly engaging the listener with all manner of music. In the home, in the office, on a train or plane – the hip-dac is the music lover’s inseparable friend.


  • Enjoy mind-blowing music at your fingertips quickly and easily with the user-friendly, compact hip-dac
  • Connect the hip-dac via USB between your smart device, laptop, and corded headphones while out and about
  • Hook it up to your PC or Mac at home or in the office
  • The hip-dac delivers hi-res, 'bit perfect' PCM and DXD up to 384kHz and up to DSD256 DSD256 as well as MQA
  • Make the most of your balanced headphones wherever you are with the hip-dac’s 4.4mm sockets
  • Reap the benefits of balanced even with normal headphones as the 3.5mm single-ended socket uses a unique S-Balanced technology to cut crosstalk and distortion in half
  • The analogue output stage of the hip-dac is a balanced (differential) design which means less interference and crosstalk
  • Tailor the sound of the hip-dac to your playback priorities with additional, exclusive iFi firmware
  • Benefit from PowerMatch – switchable gain – to cater for headphone sensitivity
  • Turn on XBass to add the missing base to open-backed headphones or IEMs

True Native

The DAC section of the hip-dac is based around a Burr-Brown DAC chip that is used extensively in iFi's products, selected for its fluid, highly 'musical' sound quality and True Native architecture.


The Burr-Brown chip, combined with a custom iFi circuitry, enables the hip-dac to deliver excellent sound quality across all manner of digital audio formats, including bit-perfect PCM, native DSD, and MQA ­– the hi-res streaming codec, as used by Tidal’s 'Masters' tier.

Hi-res audio

Hi-res PCM and DXD audio data are supported at sampling rates up to 384kHz, alongside DSD from 2.8MHz to 12.4MHz (DSD64, 128, and 256). Either side of the rotary volume control resides a pair of LEDs that change color to indicate the format and sampling rate of the digital audio being played.


Extensive clock-locking eradicates jitter (digital distortion), using a GMT Femto-precision clocking system to maintain the integrity of the digital signal until conversion to analog. The hip-dac’s USB input handles audio data up to 32-bit/384kHz and supports the 'SuperSpeed' USB 3.0 standard, as well as USB 2.0 for backward compatibility. It is asynchronous, meaning that the data rate is regulated solely by the hip-dac’s specialized audio clock circuitry for accurate, jitter-free data transfer from the source device.

Exclusive firmware

The XMOS chip used in the hip-dac, which processes audio data received at the USB input, is programmed in-house. Off-the-shelf firmware is not typically optimized for audiophile-grade sound, so iFi programs their own bespoke firmware to enhance audio processing. The hip-dac can also be tailored to your playback priorities by downloading and installing different versions of iFi exclusive firmware. Experiment with different digital filters including the GTO filter from our high-end Pro iDSD.

Balanced circuitry

The hip-dac’s amp circuitry is of balanced (differential) design. The circuitry incorporates a range of high-quality components, carefully selected for their performance in an audio context, including a custom iFi OV op-amp, TDK C0G class 1 ceramic capacitor, a precision low-noise power supply IC from Texas Instruments and a high-quality analog volume pot. The headphone amp delivers 660mW of power from the balanced output (520mW from the single-ended output) into a 32-ohm load – impressive when compared to the hip-dac’s peers, ensuring compatibility with a wide range of headphone and earphone types. With a rating of 200mW from the balanced output into a 300- ohm load, it drives most power-hungry headphones with ease.
