LAIV Harmony µDAC

The LAIV Harmony µDAC, little brother of the LAIV Harmony DAC, is also a discrete, balanced R2R DAC. However, it features an ultra-compact form factor, similar to the brand’s LEXT interfaces. Like its big brother, it supports high-resolution sampling rates up to PCM 24bit 768kHz and DSD256. LAIV has equipped its device with audiophile components within a high-end design. The digital and analog stages are galvanically isolated, and it features an Altera Cyclone IV CPLD, Accusilicon AS318 Femtosecond oscillators and a Class A discrete output stage for the most authentic and accurate sound reproduction. The µDAC boasts full connectivity: USB-B input, Toslink optical input, coaxial SPDIF input, I2S clock input via HDMI and balanced XLR output.

The µDAC is based on the same discrete balanced R2R circuit as its big brother, with each resistor carrying a tolerance of 0.05% for superior and faithful sound quality. The Class A output buffer uses discrete components for precise impedance matching, ensuring constant linearity and low noise. The digital and analog circuits are galvanically isolated to avoid ground loops and guarantee a clean, interference-free path for the sound signal.
