The xDuoo Link2 is a DAC/headphone amp that’s ready to usher in the age of micro audiophile gear. Weighing less than a AA battery, it supports 32bit/384kHz sample rates and can drive 150mW@32Ω. That’s huge power in a little bitty package. 

150mW output power

With 150mW@32Ω output to its name, the Link2 can drive IEMs, over-the-ear headphones, and even audiophile-grade cans like the Dan Clark Æon 2. 

Glass-like Transparency

With a signal-to-noise ratio (SNR) of 110dB, the Link2 vaults your music far above the noise floor, resulting in a streak-free clean sound. 

Bass Boost

Even neutral EQ lovers know that not every song is perfectly mastered. Sometimes the low-end requires a little pick-me-up. The Link2 has got you covered with its built-in +6db Bass Boost switch.
