USB-C to 3.5mm DAC Dongle
iFi - GO link
The headphone dongle linking you with your musicThe iFi Audio GO link is the missing link in your listening experience. It allows corded headphones and earphones to connect to digital devices that don’t have a 3.5mm headphone output. Even if your device does have a headphone socket, the GO link offers a big sonic upgrade. Thanks to its sophisticated DAC (Digital-to-Analogue Converter) and headphone amp circuitry, you get superior audio technology contained within smart devices and computers.
At one end of the GO link is a USB-C connector, and 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 minimize stress on the USB port where the GO link is connected.
Amazing Features
• Ultra-res PCM up to 32-bit/384kHz via USB
• DSD to 11.2MHz (DSD256)
• Full MQA decoding
High-Performance
power-efficientAt the core of the GO link is 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, along with dedicated clock circuitry utilising a specialised crystal oscillator, to deliver ultra-low distortion, excellent clarity and outstanding dynamic range. 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.
Optimised Inductance & Capacitance
individual polymer insulationThe cable that links 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
Superior ResolutionDifferent to other headphone dongles, the GO link doesn’t count on the software-based volume controls in connected digital devices, which 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 audio performance.
Headphone Heaven
reduced noise and crosstalkThe GO link’s headphone amp feeds a gold-plated 3.5mm socket, incorporating a S-Balanced configuration to minimize noise and crosstalk.
It delivers a power output of 70mW into 32 ohms, and a 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 outshines the headphone outputs built into smart devices and computers.
DRE - Dynamic Range Enhancement
improved listeningIn music production, dynamic range means the difference between the loudest and quietest sounds. It’s measured in decibels, or dB for short. In a single audio track, dynamic range means the dB difference between the loudest and quietest moment in the audio file.
You can think of the dynamic range in a system as the space between the noise floor and the clipping point. When a sound goes below the noise floor you cant tell the difference between the signal and the system noise of the medium. When a sound goes beyond the clipping point, the tops of its waveform will get abruptly cut off, causing harshness and distortion. iFi’s proprietary technology extends the Dynamic Range by 6 dB or more, for an improved listening experience.
Premium Components
Extensive jitter-eradicationExtensive jitter-eradication technologies are applied to the digital stage, including our GMT (Global Master Timing) femto-precision clock and intelligent memory buffer. This represents a total ‘out-of-the-box’ systematic digital solution that solves jitter once and for all.
Hi-Res True NativeHi-Res True Native® playback of all music formats from MP3 to DSD256, PCM384 and DXD384.
ESS Sabre Hyperstream DACDiscrete ESS Sabre Hyperstream DAC chipset with time domain jitter eliminator, discrete oscillator and 112dB dynamic range for discerning listeners.
S-Balanced circuitiFi’s exclusive S-Balanced® circuit delivers maximum performance from single-ended and balanced headphones alike.
TDK CapacitorsTDK C0G (Class 1 ceramic) capacitors offer high stability and low losses for resonant circuit applications. Getting ever closer to the theoretical ideal of pure, frequency-constant capacitance, these capacitors reduce capacitor-induced distortion to vanishingly low levels.
