LAIV Harmony uDAC

The Harmony µDAC compact audio converter employs a fully balanced discrete R2R architecture, using carefully arranged individual resistors held to a tolerance of 0.05%. This resistor ladder DAC technology eliminates the measurement compromises introduced by chip-based conversion, delivering clear, accurate sound reproduction with stable stereo imaging and a tonal character that feels true to the original recording. For listeners who prioritize authenticity, the discrete R2R DAC design provides an immersive listening experience with exceptional detail and fidelity, in a form factor that belies its performance.
