xDuoo LINK3 USB DAC & Headphone Amplifier

Dual ES9039Q2M flagship decoding in a pocket-sized dongle—the LINK3 delivers 3.5mm single-ended and 4.4mm balanced output with PCM 384kHz and DSD256 support, no drivers required.

The xDuoo LINK3 is a compact yet uncompromising USB DAC and headphone amplifier engineered for audiophiles who demand flagship-grade performance from a portable dongle.

Key Features

  • Dual ES9039Q2M DAC Chips — Flagship-Grade Decoding: The LINK3 employs two ESS ES9039Q2M chips in a dual-mono configuration, delivering an ultra-low noise floor, exceptional channel separation, and a precise, immersive soundstage. This is the same chip family found in high-end desktop DACs, now in a dongle form factor.
  • 3.5mm Single-Ended + 4.4mm Balanced Output: Full output flexibility for both standard and balanced IEMs and headphones. The 4.4mm balanced stage delivers up to 240mW @ 32Ω—significantly higher than the single-ended output—with lower crosstalk and improved dynamics for demanding loads.
  • PCM 384kHz / 32Bit & DSD256 Support: Handles virtually every high-resolution audio format with ease, from standard FLAC and WAV to native DSD64, DSD128, and DSD256 files. MQA passthrough is also supported for compatible DACs downstream.
  • Ultra-Low Noise Floor — SNR ≥120dB, THD+N ≤0.0003%: Flagship-level measured performance ensures that even the most sensitive IEMs are driven with a pitch-black background, free from hiss, hum, or coloration.
  • Plug & Play — No Driver Required: Compatible with iOS (USB-C), Android, Windows, and macOS out of the box. No software installation or driver setup needed—simply connect and listen. An OTG adapter may be required for some Android devices.
  • Compact & Portable Dongle Design: Lightweight and pocket-sized, the LINK3 is the ideal portable source upgrade. Whether commuting, traveling, or at the desk, it transforms any USB-C device into a high-fidelity audio source.
