Bartók APEX is a distillation of our past, present, and future—30 years of innovation in a single beautiful, flexible, and futureproof chassis embodying the essence of dCS. Combining a DAC, Music Streamer, Upsampler, Pre-amp, and (optional) Headphone Amplifier, the Bartók APEX offers a singular experience for headphone and stereo listeners. Now with the APEX Ring DAC, our next-generation DAC hardware, we’ve once again redefined the state-of-the-art for digital audio. This upgrade allows us to take Bartók world-leading measured performance to a new level—technology that provides an even more immersive musical experience.
APEX is a new, enhanced version of the dCS Ring DAC: the Digital 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. It remains renowned for its technical and sonic performance.
We’ve reconfigured the Ring DAC’s circuit board with APEX 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.
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.
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 directly 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.
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.
The Bartók APEX custom headphone amplifier is the embodiment of our uncompromising approach to design. Starting with the dCS analogue output stage, benchmark performance is maintained with true Class A operation through its balanced and unbalanced outputs.
Engineered to deliver a spectacular experience on both high and low impedance headphones, in balanced and unbalanced formats, it can handle a vast range of headphone models regardless of efficiency or impedance.
Its design also features dedicated power supplies for analogue and digital processing, which are isolated from the DAC section of the system for enhanced precision with minimal crosstalk and noise.
This unique architecture allows us to deliver a powerful and transparent performance that uncovers the unique character and potential of your chosen headphones.
Headphone use is simple: just plug in your chosen pair, switch the line output and adjust volume levels using the volume dial or our Mosaic control app (no need for a separate preamp). With a choice of four adjustable gain settings, you can adjust its performance to suit your setup, ensuring optimal sound across a vast range of systems.
Along with its groundbreaking amplifier, the Bartók APEX Headphone DAC features a unique processing platform that reimagines how sound is optimised for headphones. Expanse is an optional feature that can be engaged with a wide range of stereo recordings to provide a heightened sense of realism, and a greater sense of space and depth.
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™ APEX, clocking 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.
