iFi Audio GO link 2｜Portable high-resolution USB DAC headphone amplifier, supporting a 32-bit float-level high-resolution playback experience

Pocket-sized USB DAC headphone amplifier, bringing high-resolution headphone driving power to phones and computers

iFi Audio GO link 2 is a USB DAC headphone amplifier from iFi Audio. It uses USB-C computer connection and a high-resolution digital audio decoding architecture, supports PCM 32-bit/384kHz and DSD256, and delivers up to 79mW of headphone output power. Weighing only 7.8g, with a 3.5mm headphone output and bus-powered design, it is especially suitable for users who need a portable DAC, phone headphone amp, and high-resolution music playback.

Compared with the built-in audio output of traditional phones or laptops, iFi Audio GO link 2 uses S-Balanced technology and Dynamic Range Enhancement to achieve lower crosstalk, lower distortion, and clearer sonic layering; compared with entry-level portable DAC/amps in the same price range, GO link 2 stands out with higher decoding specifications, extremely low output impedance, and the ability to further adjust digital filtering via the iFi Nexis App.

Users who already own a mid-to-high-end desktop DAC and a separate headphone amp, and do not need another portable decoding device
People who mainly use Bluetooth headphones and rarely connect wired headphones, as they cannot fully realize the value of GO link 2

iFi Audio GO link 2 core technologies and features

High-resolution audio decoding: Supports up to PCM 32-bit / 384kHz and native DSD256, meeting the needs of high-resolution music files, upgraded streaming audio, and detail-focused listening.
S-Balanced technology: Introduces the advantages of balanced circuitry into a single 3.5mm headphone output, significantly reducing crosstalk and distortion for better left-right channel separation and background cleanliness.
Dynamic Range Enhancement: Enhances the contrast between loud and soft passages, making subtle tonal changes, spatial depth, and musical dynamics easier to hear.
Ultra-low output impedance design: Headphone output impedance is below 0.4 ohms, enabling more stable driving of most in-ear and portable headphones while reducing frequency response deviation.
Portable lightweight body: Measuring only 137 x 12 x 7.6 mm and weighing just 7.8g, it fits easily in a pocket, bag, or daily use with phones and laptops.
USB-C mobile compatibility: Uses a USB-C connector and works with computers and compatible Android and iOS mobile devices for straightforward mobile high-quality playback.
iFi Nexis App tuning support: Two digital filter modes, hybrid and linear, can be used via the iFi Nexis App to fine-tune the sound to personal preference.
Bus-powered: No extra battery or external adapter required; powered directly by USB for less carrying burden and greater convenience.
Practical headphone output power: Delivers 79mW @ 32 ohms and 14mW @ 300 ohms, providing useful driving performance for most portable headphones and some high-impedance headphones.
Low distortion, high signal-to-noise ratio: THD+N as low as ≤ 0.0015%, with a signal-to-noise ratio of ≥ 125 dBA, helping maintain a clean background and clear imaging.

S-Balanced single-ended balanced output technology

Although GO link 2 uses a 3.5mm headphone output, S-Balanced technology brings the advantages of balanced circuitry into a single-ended output architecture.
This design effectively reduces crosstalk and distortion, benefiting vocal positioning, instrument separation, and left-right channel clarity.

PCM 384kHz and DSD256 high-resolution playback capability

Supports decoding up to 384kHz PCM and 11.2MHz DSD, meeting the needs of common high-resolution music files and high-quality streaming.
For headphone users who value detail, airiness, extension, and low noise floor, it is clearly superior to the built-in digital audio output of ordinary phones.

Dynamic Range Enhancement

The built-in Dynamic Range Enhancement increases the contrast between loud and soft passages, making musical expression more vivid.
For classical, jazz, acoustic performances, and film scores that emphasize dynamic changes, it delivers a more three-dimensional listening experience.

iFi Nexis App digital filter adjustment

Use the iFi Nexis App to enable hybrid and linear digital filter modes and adjust the sound profile according to music type and personal preference.
This makes GO link 2 more than just a passive playback device; it also offers a degree of personalized tuning flexibility.

Ultra-light portable use and cross-platform compatibility

At just 7.8g with a slim cable design, it is ideal for everyday pocket carry, commuting, and listening on the go with a phone.
Supports macOS, Windows, Android, and iOS; compared with larger DACs that require external power, it is better suited to mobile high-quality audio needs.
