Volumio Preciso Digital to Analogue Converter

Ultra-precise, high-performance DAC. Featuring dual mono SABRE DACs, dual linear power supply, and MEMS clock for ultimate audio purity.
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.

Hyper-Symmetrical Dual Mono DAC’s
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 analogue 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.

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 analogue performance.

Precision DAC & Rivo+ Compatibility
Preciso features a dual internal linear power supply with separate regulation for the analogue and digital sub-systems, reducing interference and enhancing dynamic range. Shared with Rivo+, its dedicated USB ASIC ensures pristine data transfer, precise clocking, and optimal analogue performance. Paired with Rivo+, Rivo, or any dedicated transport, Preciso completes a fully optimized digital chain.
It can also be used as a preamp 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.

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.

Turnaround

Orders will usually dispatched within 2 working days of receiving cleared payment.

Shipping Rates

We calculate your shipping rate based on the total weight of your items and your delivery address. Standard shipping to the UK Mainland (excludes Northern Ireland, Isle of Man, Channel Islands) is free, except where specifically indicated. Don't worry, you'll always see the final shipping charge displayed before you reach the payment step (on the checkout page).

Carriers

We despatch the bulk of our UK mainland items on a 24 hour service.  Non-Mainland locations – Isle of Man, Isle of Wight, the Scilly Isles, the Scottish highlands and Islands, the Channel Islands and Northern Ireland may take a day or so longer. Smaller items are delivered using Royal Mail 24 or special delivery. Larger items are delivered using a courier service such as UPS and occasionally by a Pallet service.

Order Tracking

If a tracking # is provided by the carrier, we will update your order with the tracking information. Please note that some orders will not have tracking numbers.
