De dCS
Bartók Apex DAC is in twee uitvoeringen leverbaar,
met of zonder hoofdtelefoon
versterker.
The Modernist
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.
Arresting sound, ingenious design
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.
The Ring DAC APEX
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.
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
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.
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.
