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. 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. Balanced OUT – Provides high-fidelity audio output with improved noise rejection and superior sound quality. Optical IN – Used to connect devices or media players that output digital audio via optical cable. USB – Used to connect a computer or USB transport to the DAC for high-resolution audio streaming and playback. Trigger IN – Used to remotely power on or activate the DAC from another device (e.g. a streamer or a transport) via a 12V trigger signal. Trigger OUT – Used to pass the trigger signal to other equipment, such as turning on an external amplifier in sync with the DAC. Power IN – Connect the provided Power Supply Unit. I2S IN – Used to connect high-quality digital sources with direct signal transmission and support for DSD and high-res PCM. Coaxial IN – Used to receive digital audio signals from CD players, streamers, or other digital sources via coaxial cable. Unbalanced OUT – Standard analog output for easy integration with traditional audio systems. 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.
