The Volumio Preciso DAC is a high-performance device designed for audiophiles seeking the purest and most precise sound reproduction. The model uses two SABRE ESS9039Q2M DAC chips in a true dual mono configuration, which eliminates crosstalk and provides a wider, deeper and more natural soundstage. Thanks to its hyper-symmetrical architecture and precise channel isolation, the Preciso achieves exceptional detail and realistic imaging.
The device features an integrated hardware gain control that allows fine-tuning of the signal from 0.0 dB to -99.0 dB in 0.5 dB steps, eliminating the need for an external preamp when used with a fixed-gain amplifier. Dual internal linear power supplies with separate regulation for the analog and digital subsystems reduce interference, lower noise floor and improve dynamic range. Preciso uses a dedicated USB ASIC controller for flawless, ultra-low jitter data transfer and supports Non-Over Sampling Mode (NOS mode) for raw, authentic audio signal.
Precision starts with a single high-precision MEMS clock that drives both DAC chips for flawless synchronization and coherence. The hyper-symmetrical design features perfectly matched circuit paths for each channel, with carefully selected SMD components and C0G capacitors for stable, distortion-free operation. With a THD+n of -122.5 dB, the device pushes the limits of modern audio test equipment for truly transparent sound.
