iFi audio expands its GO series of ultra-portable DAC/headphone amps with the GO link – a headphone dongle that delivers supercharged sound when connected to smartphones, tablets, PCs and Macs via a USB port.
GO link's purpose is twofold, says iFi. First, to enable corded headphones and earphones to connect to digital devices that don’t have a 3.5mm headphone output. Second, even if a device does have a headphone socket, the GO link delivers a big sonic upgrade. Even for a company renowned for producing class-leading audio devices at affordable prices, the GO link’s price is remarkable – with an RRP of just £59/€59/$59, it’s the most affordable DAC/headphone amp iFi has ever made.
At one end of the GO link is a USB-C connector, at the other is the DAC and headphone amp circuitry, both housed in robust yet lightweight magnesium alloy enclosures. In between is a 6cm length of flexible cable – this aids practicality, allowing the DAC/amp section to be angled towards the listener and reducing stress on the USB port to which the GO link is connected. iFi hasn’t skimped on the quality of the cable, which uses silver-plated copper conductors with individual polymer insulation in a twisted pair configuration. This rotational twist helps to optimize inductance and capacitance and, also, aids noise rejection, ensuring the GO link’s sound isn’t affected by electromagnetic interference picked up from nearby electrical sources. The GO link features a 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 iFi’s dedicated clock circuitry utilizing a specialized crystal oscillator, to deliver ultra-low distortion, excellent clarity and impressive dynamic range. The GO link’ supports PCM audio data up to 32-bit/384kHz, alongside DSD up to 11.2MHz (DSD256).
The GO link’s headphone amp feeds a gold-plated 3.5mm socket incorporating iFi’s noise-reducing S-Balanced configuration, easily outclassing the headphone outputs built into phones, tablets and computers. This delivers a power output of 70mW/1.5V into 32 ohms, rising to 2V with higher impedance headphones. As well as powering headphones, the 3.5mm analogue output can be used to connect a preamp or integrated amp, or powered speakers.
