Vivaldi One

Three decades of unrivalled dCS excellence in one superlative sounding, exquisitely finished, limited-edition box…

Thirty years ago, Data Conversion Systems began a long and memorable journey. It would take the company from designing world-beating aerospace technology, to manufacturing the very finest digital source components ever made. The flagship Vivaldi series encapsulates all the collective knowledge and experience amassed over these three decades, and delivers breathtaking sound from practically any digital music format and origin.

To celebrate this most special of anniversaries, dCS has created the limited-edition Vivaldi One. This brings together most of the functionality of the redoubtable four-piece Vivaldi system, into a single, beautiful case that is offered in a choice of three breathtaking finishes. Despite its exquisite appearance, no compromise whatsoever has been made to the sound quality of what is surely the world’s best ever one-box digital source component.

At the heart of Vivaldi One are ‘next generation’ versions of the unique dCS Ring DAC board, Digital Processing Platform and Clocking System. Together, these offer exceptional linearity and ultra-low distortion. Ring DAC 2.0 has lower jitter, greater dynamic range and superior channel separation, for an even more vibrant and musical sound. This is done by FPGA chips which are custom-coded by dCS, and firmware-upgradeable long into the future.

Vivaldi One sports the finest VRDS Neo™ SACD-capable transport, network streaming and DAC functionality across a vast range of inputs. Digital volume control gives direct connection to a power amplifier, removing the need for a preamp. Its aerospace-grade aluminium casework comes in a choice of three exquisite finishes – glass-smooth Gloss White and Piano Black versions finished by HQ Lacquer, or striking 24-carat gold plate by the world-renowned FH Lambert Ltd.

The finest single-box digital music source in the world

New generation dCS Digital Processing Platform gives state-of-the-art technical performance and unrivalled musicality

Superb quality Esoteric VRDS Neo™ SACD-capable transport built in, for the best possible sound from silver disc

Accepts digital audio from many sources; USB takes PCM data up to 24/384 and DoP (DSD64 or DSD128) over PCM

Switchable variable output means Vivaldi One can be configured to work as a source component or digital preamplifier

Advanced clocking architecture plus auto-clocking mode from Vivaldi range improves ease-of-use and minimises jitter

USB digital interface runs in asynchronous mode, making Vivaldi One immune to jitter from noisy computer master clocks

Improved power supplies give lower running temperature and superior tolerance to AC mains supply variations

Multi-stage power regulation ensures that sensitive analogue circuitry is unaffected by digital interference

Separate, discrete power circuits for digital and analogue sections further enhance the purity of the power supply

Aerospace-grade machined aluminium chassis with tuned acoustic damping panels reduces resonance and magnetic effects


Utilises the latest generation dCS Digital Processing Platform for state-of-the-art measured performance and unrivalled fidelity.


Piano Black, Gloss White, 24-Carat Gold, Silver.


444mm/17.5” x 435mm/17.2” x 151mm/6.0” high. Allow extra depth for cable connectors. Allow space for air flow around the unit.



Coverter Type

dCS proprietary Ring DAC™ topology, with a choice of 3MHz or 6MHz operation.

Analogue Outputs

Output Levels: 0.2V, 0.6V, 2V or 6V rms on all outputs for a full-scale input, set in the menu. Balanced Outputs: 1 stereo pair on 2x 3-pin male XLR connectors (pin 2 = hot, pin 3 = cold). These outputs are electronically balanced and floating, the signal balance ratio at 1kHz is better than 40dB, Output impedance is 3Ω, maximum load is 600Ω (a 10kΩ-100kΩ load is recommended). Unbalanced Outputs: 1 stereo pair on 2x RCA Phono connectors. Output impedance is 52Ω, maximum load is 600Ω (a 10kΩ-100kΩ load is recommended).

Digital Inputs

USB 2.0 interface on a type B connector. Operates in asynchronous mode, will accept PCM data up to 24 bits at 44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384 kS/s and DoP (DSD/64 or DSD/128 over PCM) in USB Audio Class 2 mode, can operate in Class 1. 4x AES/EBU on 3-pin female XLR connectors. Each will accept up to 24 bit PCM at 32, 44.1, 48, 88.2, 96, 176.4, 192kS/s & DoP/64 OR 2x Dual AES pairs at 88.2, 96, 176.4, 192, 352.8, 384kS/s & DoP/64, DoP/128 plus dCS encrypted DSD. 3x SPDIF on 2x RCA Phono and 1x BNC connectors. Each will accept up to 24 bit PCM at 32, 44.1, 48, 88.2, 96, 176.4, 192kS/s & DoP. 1x SPDIF optical on a Toslink connector, will accept up to 24 bit PCM at 32, 44.1, 48, 88.2 & 96kS/s. 1x SDIF-2 interface on 2x BNC connectors, will accept up to 24 bit PCM at 32, 44.1, 48, 88.2 & 96kS/s or SDIF-2 DSD (auto-selected). This interface requires a compatible Word Clock input, locked to the data rate.

Worldclock I/O

3x Word Clock inputs on 3x BNC connectors, accept standard Word Clock at 32, 44.1, 48, 88.2, 96, 176.4 or 192kHz. The data rate can be the same as the clock rate or an exact multiple (0.25x, 0.5x, 1x, 2x, 4x, 8x) of the clock rate. Sensitive to TTL levels.

Word Clock output on 1x BNC connector. In Master mode, a TTL-compatible 44.1kHz Word Clock is available. In Universal Master Mode a 38.4kHz Word Clock is available for use with the Vivaldi Upsampler.
