The dCS Bartók APEX is a high end DAC, Music Streamer, Upsampler, Pre-amp, and (optional) Headphone Amplifier, the Bartók APEX offers a singular experience for headphone and stereo listeners. The new APEX Ring DAC is dCS next-generation DAC hardware, who have redefined the state-of-the-art sound for digital audio. This upgrade takes the Bartók world-leading performance to a new level that provides an even more immersive musical experience.

'The performance of the Bartók is nothing short of breathtaking'

The Bartók APEX retains the original's powerful, dynamic and detailed soundscape and adds elements of resolution and refinement previously only achievable with the Rossini or Vivaldi APEX. dCS engineered Bartók APEX to inform and inspire.

APEX sets a new benchmark for transparency. It organically resolves the finest details and uncovers textures and subtleties that most systems overlook. From the broadest dynamic swings in volume to the subtlest shifts in tone, Bartók APEX reveals each aspect of a recording with a sense of effortless refinement and control.

Designed and hand-assembled at our headquarters in Cambridgeshire, England, Bartók APEX is born from meticulous craft, exhaustive development, and obsessive attention to detail—a relentless pursuit of musical purity that has inspired us to reimagine the limits of sound reproduction. 

Sharing the same electronics as our Vivaldi and Rossini systems, it features the latest generations of our pioneering Ring DAC™ APEXclocking architecture, and digital processing platform —a unique combination of hardware and software unrivalled in its sonic and technical performance.

Bartók APEX combines precision engineering with an elegant and timeless aesthetic. Standard-setting build quality means Bartók APEX withstands even the most intensive use and reliably delivers superb sound quality at all volume settings and outputs. With flexible and upgradable software and hardware, Bartók can grow and evolve, providing a state-of-the-art listening experience for years to come.


APEX is a new, enhanced version of the dCS Ring DAC: the Digital to Analogue conversion system found inside all dCS DACs. First developed for our professional audio products, this unique system has been subject to continuous development and refinement over the past three decades, and remains renowned for its technical and sonic performance.

With APEX, we've reconfigured the Ring DAC's circuit board and developed a new analogue output stage. This has allowed us to further reduce distortion, and increase linearity, resulting in a range of measured and sonic improvements - including an even greater sense of dynamic drive, detail, finesse and vitality.

High-performance streamer

Designed for ease of use and superior sound, the Bartók APEX can flex to serve whatever mood or music you ask it to. With its wide range of inputs and outputs, high-performance UPnP streamer, and extensive choice of filters, it offers limitless capabilities and an effortless listening experience.

Streaming Services

Compatible with all major file formats, it provides instant access to music from a wide range of streaming services, including Roon, TIDAL, Spotify, Qobuz, Deezer and Internet Radio. It also plays files direct from personal devices or storage drives via USB, AES or S/PDIF inputs, and from Apple devices using Apple Airplay.


Its streaming interface supports all major lossless codecs, plus DSD in native and DoP formats, and ensures true 24-bit resolution audio when streaming via Ethernet. Playback is easily managed via our Mosaic app, which allows you to access music from multiple sources and adjust the settings on your system through a single, intuitive interface.

Mosaic APP

Available on all Android and iOS devices, the Mosaic control app is supported by a powerful processing platform that runs on custom code developed by dCS. This software-driven design means its performance can be upgraded and enhanced over time, allowing us to add new streaming functionalities as platforms and services develop.
