From desktop to destination

The xDuoo Link2 Bal Max is a DAC/Amp you can take anywhere, whether that's your workdesk or an exotic destination. Its true balance design puts out loads of power while keeping crosstalk and noise as low as a dedicated desktop rig. And with a USB Type-C port, it can be used with next-gen tablets and the Nintendo Switch. 

What’s new in the Max?

The xDuoo Link 2 Bal Max is the successor of the Link 2 Bal. In this version, xDuoo introduces better signal-to-noise ratio, more single-ended output power, and better crosstalk performance. The result is a portable DAC/Amp that’s closer than ever to giving a desktop rig a run for its money. 

True balanced decoding

Each audio channel is separately decoded with its own Cirrus CS43131 D/A chip, providing higher resolution, greater signal-to-noise ratio, and less crosstalk than non-balanced decoding architectures. 

Music, movies, gaming, and more

Listen to hi-res music from a laptop, take movie night to the next level with hi-fi sound, or up the Nintendo Switch’s audio game. The Link2 Bal Max’s USB Type-C port has you covered in every situation. 

Seamless chassis 

With 2.5D double-sided glass and full-body CNC processed aluminum, the Link 2 Bal Max has a singular chassis with no seams or screws. 

Be sure of your sound

The Link2 Bal Max’s LED light will change colors with the sample rate of the song: red for CD-quality PCM, blue for super-CD quality PCM, and green for DSD.
