On December 21, we’re releasing an update for dCS Mosaic – our custom platform which allows dCS customers to access a wide range of digital music and control the settings on their dCS device.

Mosaic 1.1.1 will include a host of improvements and new features available to all dCS owners, as well as a new innovation, dCS Expanse, designed specifically for owners of our Bartók Headphone DAC.

Expanse is a custom-built processing platform, designed to deliver an enhanced headphone experience on the Bartók Headphone DAC.

Developed by dCS, it was created to address a growing imbalance in the way that sound is monitored during the recording process and how it’s experienced during playback. With most recordings still monitored on loudspeakers, and more people than ever now listening to music on headphones, we felt there was a need for a platform that could bring the headphone experience closer to the sound that artists and engineers hear when listening to a performance or mix in the studio.

Various technologies have been developed to address this imbalance over the past few decades – most of which focus on using cross feed to move a perceived sound source out of a listener’s head and into the room in front of them, mirroring the effect of listening to music on loudspeakers.

Yet after studying existing methods of cross feed and headphone optimisation, we discovered that none of them were able to optimise sound while also preserving the original reverberation in a recording. Most instead relied on adding artificial reverberation – a technique we didn’t feel was appropriate for dCS products.

So, after extensive research, our R&D team used their expertise to develop an alternative approach that allows us to externalise sound, without loss or damage to the original reverberation.

This unique method allows us to deliver a more immersive experience – one that captures not just the fine details in a musical performance, but the overall sense of space and depth, something that is often lost when sound is translated for headphone listening.

With Expanse, listeners can enjoy all of the hallmarks of dCS playback – clarity, precision and an engaging sound – and a unique experience that remains faithful to the music.

You can find out more about Expanse here.

We’ve also put together a playlist featuring some featuring some recommended reference tracks to help you discover the platform’s potential, which you can access here.

What else is new?

 Expanse is just one of several new features and updated included in Mosaic 1.1.1

Other additions include TIDAL My Mix, which provides added support for TIDAL’s autogenerated playlists, an update to our play queue feature, which allows listeners to add more tracks to a play queue or playlist, and improvements to media browsing, playback and control functions.

Mosaic 1.1.1. is available to download from 10am GMT on Monday, December 21. Further information will be shared via our website and social media pages, and on our forum,

If you have any questions regarding Expanse or Mosaic 1.1.1, please do not hesitate to contact me.

If you require an offline update, please contact us and provide your unit serial number. We will provide you with an update image that will only install on that unit, so it is critical that the serial number be correct. Installation instructions will be provided with the update image. This service will be available from 4th January 2021.


dCS announces its new Vivaldi 2.0 series – bringing a comprehensive package of improvements to what many regard as the best digital music source in the world.

The original Vivaldi was launched in late 2012 to widespread critical acclaim. Music industry professionals and audiophiles alike declared it to be the finest sounding digital front end on sale.

Comprising the Vivaldi Transport, Vivaldi DAC, Vivaldi Upsampler and Vivaldi Master Clock, this cost-no-object, flagship system pushed the boundaries of what was then possible with digital replay. Vivaldi processed practically every digital format and offered a vast array of input and output configurations. At its heart was the dCS Ring DAC™, a unique, bespoke-designed digital converter that offers superlative sound quality and technical performance.

As with every dCS product, subsequent firmware updates have improved its functionality and performance. Now though, dCS has made a number of landmark hardware and software improvements to the system, warranting the 2.0 suffix. The changes are designed to make Vivaldi easier to use, more flexible and even better sounding.

The disc transport in the new dCS Rossini Player does not support the Super Audio Compact Disc format, although it does play the standard CD layer of hybrid SACDs in 16/44.1 PCM Red Book quality. Read more in the attached brieifing.

dCS is proud to announce its new Rossini series – designed to make superb sounding digital music from any source more easily accessible.

A premium-priced complete digital front end that replaces Puccini in the dCS range, it comes in two versions – the £15,000 Rossini DAC and £18,000 Rossini Player; setting the new performance standard for single-box digital systems.

Rossini DAC features an array of digital audio inputs and is able to stream music from NAS drives and streaming services such as TIDAL™, Spotify™ and Deezer™ over Ethernet, from Apple devices via Airplay™, and audio via industry-standard USB, AES and S/PDIF digital inputs. Rossini Player adds an integral, high quality Compact Disc transport for silver disc playback.

In an industry where most high end manufacturers adopt a build-by-numbers approach, using generic technology lightly repackaged to suit commercial needs, there are few companies that go their own way. Data Conversion Systems (dCS) is one. This specialist British brand stands apart because all the elements of its digital audio playback systems are designed, developed and assembled in the United Kingdom using unique proprietary technologies, accrued from twenty five years at the cutting edge of digital audio recording and playback. So, what does a dCS system sound like and why are they so remarkable?

At dCS’s facility just outside Cambridge a small team of highly skilled technicians builds a limited number of units each month. Every dCS product – whether it be a Digital Audio Converter (DAC), CD/SACD Transport, Digital to Digital Converter or Master Clock – is individually hand-assembled in a process that takes two full weeks. During that time it is subjected to a battery of extremely rigorous and demanding tests to ensure that by the time it leaves the company’s premises every single parameter of its measured performance is guaranteed to be within the very fine tolerances demanded by the company and that there is not a single blemish anywhere to spoil its beautiful finish and elegant appearance.

Ten things about Britain’s greatest purveyor of premium digital music playback sources…

dCS’s culture of cutting-edge engineering, that is the result of its twin heritage in both defence systems and professional audio, led to a number of ‘world firsts’ in the audio field.  The company pioneered high resolution audio, developing converters capable of supporting 24/192, DSD* and DXD* audio formats. Not only were the world’s first high resolution (24/88.2) and surround Super Audio CD (SACD) recordings created using dCS technology, but the company was the first to develop outboard upsamplers and master clocks, demonstrating to music lovers worldwide the importance of these technologies and how they could get listeners much closer to the original musical performance.

dCS celebrates its twenty-fifth anniversary in 2014. It has been a remarkable quarter of a century for the Cambridge company, during which time it has changed the face of digital audio recording and playback around the world. In its twenty-fifth anniversary year, dCS is looking back at its legacy, celebrating its tradition of innovation and engineering excellence, and reviewing its many technological milestones along the way.
