DCS Vivaldi APEX DAC
The digital heart of the Vivaldi system, our world-famous DAC decodes audio with astonishing focus. With its proprietary hardware and software, it delivers a performance unmatched in its depth, realism and emotion
Vivaldi DAC uses the latest groundbreaking dCS technology including ‘next generation’ versions of the dCS Ring DAC™, Digital Processing Platform and Clocking System so that, as the hub of a digital audio system, an array of features guarantees superlative performance from any digital source.
Vivaldi DAC features standard AES3, Dual AES, SDIF-2 and S/PDIF inputs in addition to an asynchronous USB 2.0 interface. The enhanced digital volume control allows direct connection to a power amplifier so that in the majority of systems there is no need for a separate preamplifier. Maximum output can be set any one of four levels to suit different amplifier and speaker combinations.
The unique design of the legendary dCS Ring DAC™ combines exceptional linearity with very high speed operation enabling it to deliver true 24-bit performance even at low signal levels. The latest generation of our proprietary Ring DAC™ incorporates a number of important technical advances that have resulted in enhanced dynamic range, reduced jitter, improved channel separation and greatly improved musical realism. The new double-speed mapping feature adds even more delicacy, emotion and presence to this award-winning design.
The powerful digital processing platform of Vivaldi DAC is based around Field Programmable Gate Array (FPGA) chips, Digital Signal Processing (DSP) chips and a microcontroller system. All use code developed and maintained in the UK by dCS. Offering twice the logic capacity of previous generations, Vivaldi DAC is the current state-of-the-art in digital audio, delivering unmatched sonic and measured performance.
dCS pioneered the use of external clocks in digital audio systems, and the redesigned multi-stage Phase-Locked-Loop (PLL) system used in Vivaldi DAC sets world-beating standards for accuracy and control of troublesome jitter from the incoming audio stream.
Featuring a completely new interface designed to handle all high resolution musical formats up to DXD (24-bit data at 352.8 and 384kS/s) plus DSD/64 or DSD/128, the optimised DSP filters available to Vivaldi DAC owners will ensure you can extract every last nuance of musical detail and emotion by tuning the system to suit your personal preference.
The dCS ‘soft’ approach to programmable logic makes it extremely easy for users to update Vivaldi DAC software, whether adding new features, installing performance upgrades or adapting to changes in digital formats.
Used as a standalone DAC or as part of a complete Vivaldi digital audio playback system Vivaldi DAC gives a performance of effortless realism each and every time.
Designed for the ultimate listening experience, the Vivaldi represents the pinnacle of our uncompromising approach to audio engineering. With a dedicated DAC, Upsampler, Clock and CD/SACD Transport, it separates the core aspects of the playback process to deliver a performance that is both technically precise and musically profound
With total precision and composure, the Vivaldi unravels even the most complex recordings with ease, projecting a sound that feels utterly natural and beautifully complete. Under its delicate hand and invisible touch, music comes alive, with each note unfolding to reveal an arresting performance and a panoramic view of a recording or mix.
There is an assured confidence that flows from Vivaldi. From the smallest inflections to the swiftest shifts in tempo and tone, it captures it all with a sense of perfect rhythm and flow. With its wide and far-reaching gaze, it uncovers not just the fine details in a recording, but the silences and spaces in between – the tension, drama and emotions that lie beneath.
Crafted for the purest musical expression, the Vivaldi is designed to disappear, leaving you absorbed in sound and immersed in the world that an artist creates. Its pioneering architecture builds on three decades of innovation to present our most ambitious product yet: a four-box system that offers unmatched processing power, almost limitless potential and absolute integrity.
With the Vivaldi’s launch, we set out to devise a blueprint for a new generation of digital playback systems. Through exhaustive research and development, we reimagined our core technologies – including our Ring DAC, clocking architecture and digital processing platform – developing a technical DNA that has shaped the creation of each dCS product since.
The unique technologies at the heart of Vivaldi allow us to deliver an unrivalled sonic and technical performance, and a listening experience that is unmatched in its musical expression and ability to communicate with you, the listener. A product of visionary thinking and fearless engineering, it redefines state-of-the-art and brings a new level of realism to digital playback.
Vivaldi has received huge critical acclaim the world over, winning numerous global awards for its sonic performance and ground-breaking flexible architecture. It remains the most revealing and lowest distortion playback system available, and as its design is flexible, we can continue to refine and enhance its performance over time via simple software upgrades.
Compatible with all high-resolution music formats, the Vivaldi is a system that can flex to serve whatever mood or music you ask it to. Whether you’re streaming or spinning discs, it offers superlative sound and an effortless listening experience. And with its wide range of settings and filters, its performance can be tailored to suit your music collection and audio setup.
The Vivaldi DAC features AES3, Dual AES, SDIF-2 and S/PDIF inputs, along with an asynchronous USB 2.0 interface. Its enhanced digital volume control allows direct connection to a power amplifier, removing the need for a separate preamp, and its maximum output can be set to one of four levels to suit a range of amplifier and speaker combinations.
Thanks to its high-performance UPnP streamer, the Vivaldi upsampler provides instant access to audio from a wide range of streaming services, including Roon, TIDAL, Spotify, Qobuz, Deezer and Internet Radio, as well as external devices and storage drives. Add a CD/SACD Transport and you have a system that delivers extraordinary sound from any digital source.
Playback is easily managed via our Mosaic platform, which allows you to browse music from multiple libraries and adjust the settings on your dCS system through a single mobile app. Available on all Android and iOS devices, it provides endless choice and complete control over your listening experience through a simple, intuitive interface.C

DAC Key Features
- Utilises the latest generation dCS Digital Processing Platform for state-of-the-art measured performance and unrivalled fidelity
- Designed for maximum flexibility by accepting audio data from a variety of digital sources
- Flexible output configuration can be optimised in systems with or without preamplifiers
- Comprehensive clocking architecture plus an auto-clocking mode used in the Vivaldi range improves ease-of-use and minimises jitter
- USB interface allows easy connection to a computer, accepting PCM data at up to 24/384 and DoP (DSD/64 or DSD/128 over PCM)
- The interface runs in asynchronous USB mode, making the DAC immune to jitter from noisy computer master clocks
