iFi Audio has released the GO link 2 Max, a compact USB-C audio converter and amplifier. This $85 device utilizes dual ESS Sabre chips for high-fidelity sound on mobile and desktop platforms.
The $85 dual-mono architecture
The GO link 2 Max distinguishes itself in the budget category by employing a dual-mono arrangement. As the report says, this configuration dedicates one ESS Sabre chip to the left audio channel and another to the right, a design choice intended to lower the noise floor and reduce crosstalk. This architecture allows the device to provide up to 241mW of output power, making it capable of driving a wide variety of headphones and in-ear monitors.
To accommodate different listener preferences, iFi Audio included both a 4.4mm fully balanced output and a 3.5mm S-Balanced single-ended output. the S-Balanced circuitry is particularly noteworthy, as it applies balanced design principles to the standard 3.5mm jack to cut channel crosstalk by approximately half compared to traditional single-ended connections.
Boosting dynamic range by 6dB via proprietary tweaks
Beyond the hardware layout, iFi Audio has applied custom software and hardware refinements to the ESS Sabre chipset. one of the most significant features is Dynamic Range Enhancement, which the source claims adds up to 6dB of extra dynamic range between a track's quietest and loudest passages. This is paired with Quad DAC+ technology and a Time Domain Jitter Eliminator to ensure high-fidelity playback.
The device also incorporates iFi's GMT clock circuitry and a dedicated crystal oscillator to improve timing and reduce distortion . These technical layers support high-resolution formats,including PCM playback up to 384kHz and native DSD256. this makes the GO link 2 Max a viable tool for listeners using high-fideliity streaming services such as Tidal or Qobuz.
A low-power solution for mobile audiophiles
The rise of the "dongle DAC" represents a broader shift in the audio industry, where users increasingly seek to upgrade mobile audio without the bulk of a dedicated Digital Audio Player (DAP).. The GO link 2 Max fits this trend by prioritizing power efficiency. The choice of ESS Sabre chips was driven in part by their low power draw, ensuring that the device does not rapidly deplete the battery of a connected smartphone or laptop.
To further protect signal integrity, the included cable uses silver-plated copper conductors. These are arranged in a twisted-pair configuration with individual polymer insulation to reduce inductance and capacitance. According to the report, this specific construction helps the device reject electrical interference from nearby electronic sources, which is critical for a device intended for mobile, on-the-go use.
The Android-centric iFi Nexis app ecosystem
Despite the hardware's versatility, the current software ecosystem presents a potential limitation for some consumers. The iFi Nexis app, which is required for over-the-air firmware updates and the customization of digital filter profiles,is currently only available for Android devices. This leaves a significant question for the massive iPhone user base: will iFi Audio release an iOS version of the Nexis app to allow for full customization?
Furthermore, while the device is marketed as being able to drive demanding high-impedance models, the source does not provide specific impedance ratings or a list of tested headphones.. It remains to be seen how the 241mW of power will perform against the most power-hungry audiophile headphones on the market.
