iFi Audio Hip-Dac 3

Shooting from the hip

With its sleek, robust aluminium enclosure measuring 10.2x7x1.4cm, the go-anywhere hip-dac 3 is designed to slip discretely into a pocket or bag. It replaces the inferior DAC (digital-to-analogue converter) and amp circuitry in phones, 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 digital device via USB, plug in your favourite corded headphones or IEMs and the hip-dac 3 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 3 is a music lover’s inseparable friend.

DAC’s the way to do it

The DAC section is based around a Burr-Brown chipset that iFi uses extensively, selected for its natural-sounding ‘musicality’ and True Native architecture. Its design allows DSD and PCM audio data to take separate pathways, thereby remaining ‘bit-perfect’ in their native form right through to analogue conversion. This, combined with custom iFi circuitry, enables the hip-dac 3 to deliver excellent sound quality across all manner of digital audio formats.

iFi’s experience with the Burr-Brown chipset means it knows how to make the most of it; but whilst intrinsic to the resulting sound, the creation of an exemplary DAC stage involves much more than the selection of a particular DAC chip. One such critical component is the XMOS chip that iFi uses to process audio data received over the digital inputs. The hip-dac 3 incorporates a 16-core XMOS microcontroller, its processing power utilised by iFi to optimise sound quality and unlock the full potential of the Burr-Brown DAC chip.

Balance of power

The hip-dac 3’s analogue amplification stage benefits from a true balanced (differential) circuit design – unusual in a DAC/headphone amp anywhere near this price point. This topology helps to reduce signal distortion, which in turn leads to purer, more engaging sound.

The circuitry incorporates a range of high-quality components selected for their performance in an audio context, including a custom iFi OV op-amp, a precision low-noise power supply IC from Texas Instruments and a high-quality analogue volume pot. (Many portable DAC/headphone amps use digital volume controls, which can be detrimental to sound quality.) The amp stage can deliver up to 400mW into a 32-ohm headphone load, ensuring compatibility with a wide range of headphone and earphone types with power to spare. Even high impedance headphones are handled with ease thanks to output voltage of 6.3V into 600 ohms (from the balanced output).
