iFi Audio GO link - Portable Hi-Res Headphone Amplifier & USB-C DAC - 3.5mm

1 review

HIGHLY ADVANCED DAC
Rarely implemented high-end features such as adjustable analogue gain with DRE (Dynamic Range Enhancement) plus technologies to minimise THD (Total Harmonic Distortion) and crosstalk are possible due to the DAC chip’s advanced specification.

DAC’S THE TICKET
At the heart of the GO link lies a power-efficient, high-performance DAC chip from ESS Technology’s Sabre HiFi series – the ES9219MQ/Q – benefiting from 32-bit HyperStream III architecture. This combines with Quad DAC+ and Time Domain Jitter Eliminator technologies, plus our dedicated clock circuitry utilising a specialised crystal oscillator, to deliver ultra-low distortion, excellent clarity and impressive dynamic range.

DO THE TWIST
The cable linking both sections together uses silver-plated copper conductors with individual polymer insulation in a ‘twisted pair’ configuration. This rotational twist helps to optimise inductance and capacitance and also aids noise rejection. The GO link’s sound isn’t affected by electromagnetic interference picked up from nearby electrical sources.

MOVE WITH THE MUSIC
Unlike other headphone dongles, the GO link doesn’t rely on the software-based volume controls in connected digital devices. This can adversely affect audio resolution. Instead, adjusting the volume on the connected device controls the volume level in the GO link’s DAC, not in the phone, tablet or computer. This hardware-based volume control is another feature that helps to deliver the GO link’s superior sonic performance.

HEADPHONE HEAVEN
The GO link’s headphone amp feeds a gold-plated 3.5mm socket, incorporating our S-Balanced configuration to reduce noise and crosstalk. It delivers a power output of 70mW into 32 ohms, and a maximum voltage output of 2.05V into 600 ohms. This gives it plenty of oomph to drive the kind of headphones and earphones likely to be used with the GO link and easily outclasses the headphone outputs built into smart devices and computers.

HI-RES IN GLORIOUS COLOUR
The GO link’s hi-res audio credentials are highly impressive given its diminutive size and price tag. An LED changes colour to indicate the incoming audio format – PCM, DSD or MQA – and the PCM/DSD sample rate (PCM to 32-bit/384kHz, DSD to 11.2MHz (DSD256) and MQA).
