Ultra-Lightweight Hi-Res Audio DAC & Headphone Amplifier Designed for Phones and Laptops

The ifi Audio Go Link 2 is an ultra-portable USB DAC/amp launched by ifi Audio, featuring the award-winning ESS Sabre DAC chip and supporting Hi-Res Audio formats up to 384kHz PCM and DSD256. Its core design aims to bypass the ordinary sound chips built into phones, tablets, and laptops, providing clean, powerful, and detailed audio output for your 3.5mm headphones through independent digital-to-analog conversion and amplification circuits. It is the most direct solution for improving phone audio quality.

Compared to most similar portable DACs on the market that only offer basic decoding, the Go Link 2 incorporates ifi's exclusive S-Balanced® balanced circuit technology and Dynamic Range Enhancement. This not only significantly reduces channel crosstalk in single-ended output but also noticeably boosts the music's dynamics and tension, delivering an immersive listening experience that belies its size. Weighing only 7.8 grams, it is the lightest ifi DAC product ever.
