THE ULTIMATE EXPRESSION OF PRECISION
Preciso is Volumio’s ultimate expression of what a DAC can and should be. It is the result of obsessive engineering, relentless refinement, and a singular goal: to deliver the purest, most precise audio signal without breaking the bank. Preciso is the ultimate expression of everything we've learned at Volumio in crafting award-winning digital audio players.
WHY PRECISO?
  Named after the Italian word for precise, Preciso lives up to its name through uncompromising engineering and sonic accuracy. It features dual SABRE ESS ES9039Q2M DACs in a true dual mono design, eliminating crosstalk for a wider, deeper, and more natural soundstage. Its hyper-symmetrical architecture ensures precise channel isolation and lifelike imaging, while a THD+n of -122.5 dB reaches the limits of modern audio test equipment for truly transparent sound. Enhancing its versatility, Preciso also includes an integrated Hardware Gain Control, eliminating the need for an external pre-amplifier when paired with a fixed-gain power amp. This gain control allows fine-tuned signal adjustment from 0.0 dB to -99.0 dB in precise 0.5 dB steps, offering both convenience and high-fidelity performance in a single, streamlined solution.
BUILT ON THREE CORE DESIGN PILLARS
HYPER-SYMMETRICAL DUAL MONO DACS Dual ESS ES9039Q2M in perfectly mirrored, isolated circuits for absolute channel separation, lowest crosstalk and extreme optimization of the DACs signal path.  
DUAL LINEAR POWER ARCHITECTURE Independent power regulation for analog and digital paths ensures a noise-free signal.
BEST IN CLASS WHERE IT COUNTS Carefully selected components like a precision MEMS clock, premium OPAMPs, and an ASIC USB interface ensure clean, stable performance, while built-in Hardware Gain Control offers precise 0.5 dB step adjustment, removing the need for an external preamp.
HIGH-PRECISION DAC ARCHITECTURE WITH RIVO+ COMPATIBILITY
Preciso features a dual internal linear power supply, with separate regulation for the analog and digital sub-system. This complete isolation reduces interference, lowers the noise floor, and enhances dynamic range.When paired with RIVO+ , Rivo or any dedicated transport, Preciso becomes part of a fully optimized digital chain. Preciso uses the same dedicated USB ASIC found inside RIVO+. This ensures pristine data transfer, precise clocking, and optimal analog performance. Preciso can be also used as a Pre-Amp with hardware gain control for direct integration with power amplifiers.
NOS MODE NOW AVAILABLE
Preciso now supports Non-Over Sampling Mode ( NOS mode), a highly requested feature for the most discerning audiophiles. When enabled, NOS mode disables oversampling to deliver a raw, unprocessed audio signal closer to how the music was originally recorded.
DIGITAL THAT DELIVERS
Preciso combines a dedicated ASIC USB controller for bit-perfect, ultra-low jitter transfer with the highest-grade operational amplifiers for exceptional analog performance.
OUTSTANDING PERFORMANCE INDICATORS
With a THD+N of -122.5 dB, Preciso operates at the measurement threshold of today's most sensitive audio test equipment, delivering exceptionally clean and accurate sound reproduction.

PRECISION CLOCKING AND SYMMETRICAL DESIGN
  Preciso’s precision starts with a single high-accuracy MEMS clock driving both DACs for impeccable timing and coherence. Its hyper-symmetrical design features perfectly matched circuit paths for each channel, with carefully selected SMD components chosen not only for compactness but also for superior electrical performance, and C0G capacitors that ensure stable, distortion-free performance over time and varying temperatures.
