The xDuoo Link3 is a battery-free USB DAC/amp with dual ES9039Q2M DACs, an XMOS XU316 USB chip and dual SGM8262 amps, rated up to 1000mW at 32Ω balanced when its second USB-C port has external power. It suits phone and laptop listeners who want high output power, a color screen and microSD playback in a 70g unit.
Who the xDuoo Link3 is for
Power-hungry headphones: With external power, Super Power Mode is rated 1000mW at 32Ω balanced and 500mW single-ended; on USB bus power alone it is rated 700mW and 360mW.
Phone listeners: The second USB-C port (PD 3.0) powers the Link3, switches on Super Power Mode and charges the phone at the same time.
Big libraries on small phones: In HUB mode, a microSD card up to 2TB (FAT32 or exFAT) shows up on the phone or computer, which plays its files through the Link3; xDuoo suggests external power for HUB mode on phones.
Consoles and movies: A UAC 1.0 mode (up to 16-bit/48kHz) covers Switch and PlayStation consoles, and EQ presets include Music, Movie and Game.
Skip it if: you want a stick-size dongle; it measures 10.7 × 3.8 × 1.5cm and weighs 70g, needs a second power source for its full 1000mW, and needs external power on Lightning iPhones.
