thus delivers a new level of sound quality from any source. For all your
to drive higher quality headphones effortlessly. In addition, the DA-10
connection needs, USB-A, USB-B micro and AUX input are integrated.
Personalized Listening
While portable audio players, smartphones and tablets can easily power ordinary ear buds, their analogue audio output stages
typically can’t handle higher impedance headphone types, and
the quality of their internal D/A conversion isn’t up to the standard that serious music listeners desire. That’s where the DA-10
changes the game and takes over. With its advanced audio technologies engineered by Denon audio expert the DA-10 brings all
the details, all the bass, all the excitement back to life. This is not
only noticeable by high price audiophile headphones, but also
easily noticeable with standard, yes even ordinary in ear buds.
Just get more punch, more finesse and just play it louder and
with more dynamic.
Universal audiophile playback of digital music files and
streaming audio
The USB-B input enables computer stored music files or streaming audio from internet music, video and film services to be
processed and played via the DA-10 for the highest possible
sound quality. The computer recognises the DA-10 as an external soundcard, completely bypassing its own lower quality audio
• High definition, portable headphone amplifier with D/A Converter
• USB Audio and Micro USB-B inputs
• Analogue input and output
• Universal bit-transparent, asynchronous playback of digital
audio file formats and streaming audio from computers
via Micro USB-B; up to 24 bit, 192 kHz and DSD 2.8MHz
and 5.6MHz native support
• Headphone amplifier stage, for superb listening with all kinds of headphones or in ears

electronics. Any digital audio format that can be played from the
computer’s own media player can be processed by the DA-10 –
including MP3/MP4, AAC, ALAC, WAV and FLAC HD (up to 24 bit,
192 kHz) and DSD (in 2.8MHz and 5.6MHz resolution). Transmission of the digital audio stream from the computer to the DA-10
is in bit-transparent, asynchronous mode, to ensure a bit-perfect
datastream for high definition Advanced AL32 Processing and
High- Precision 32 bit, 192 kHz digital to analogue conversion.
High definition signal processing and D to A conversion
Denon’s Advanced AL32 Processing and High-Precision 32 bit,
192 kHz digital to analogue conversion delivers audio quality far
in advance of usual high definition, wide bandwidth conversion
techniques. Just as advanced Blu-ray players can deliver full HD
video from standard definition DVD, the Advanced AL32 processor up-converts and up-samples all input signals to a 32 bit,
192 kHz high definition datastream, which is interpolated, using
a highly advanced proprietary algorithm, to provide a full scale,
accurate reproduction of the original sound recording. The Advanced AL32 processor is matched with an High-Precision 32 bit,
192 kHz D to A conversion (DAC) circuit to fully exploit the
• High quality audio components for rich, open, detailed sound
• Denon Advanced AL32 Processing and High-Precision
32 bit, 192 kHz digital to analogue conversion for exceptional
high definition audio quality
• DAC master clock design for distortion free, fully transparent sound stage
• Independent master clock crystals (44.1kHz and 48kHz)
accurately clock incoming signals at any sample frequency
• Discrete Current Buffer for Headphone Output
• Audiophile analogue output stage matched to fully exploit
high definition 32 bit, 192 kHz D to A signal conversion for the
same astounding sound quality as Denon’s top of the range
CD / SACD players
Advanced AL32 high definition processing. Quantization noise,
inherent in standard resolution digital audio conversion, is rendered inaudible and digital processing and filtering artifacts are
moved far beyond the range of human hearing, so as to reproduce the purist, highest possible quality analogue output signal.
DAC Master Clock design
A master clock design of exceptionally accuracy been placed
immediately next to the DAC circuit, to provide the greatest accuracy in the D to A signal conversion and reduce to the absolute
minimum timing anomalies in the conversion process – known
as jitter – that are a significant source of distortion. The design
features a low jitter oscillator to generate the clock signals. Two
crystals – at 44.1 and 48 kHz – are incorporated, to generate the
most accurate clock for incoming signals of any sample frequency (incoming signal sample frequencies being a multiple of one
or other of the crystals – e.g. 192 kHz = 4 x 48 kHz; 88.2 kHz x
44.1 kHz). The effect is to ensure reproduction of a fully realistic
and transparent stereo sound stage, with accurate localization of
instruments and performers.
