以下摘自Audionet主页关于此机的介绍：
The creation of the DNA (Digital Network Amplifier) began with a single aim:
to build the best sounding and most versatile integrated amp possible, capable
of interacting with all current music reproduction sources. R&D was allowed to
operate with uncompromising rigor and dedication at all phases, leading to the
DNA’s astonishing powerful performance, innovative digital and analogue
signal processing and circuit design. The Audionet DNA is therefore more than
a stellar integrated amplifier – it is a universal interface for digital
music, and an audiophile’s power station. Reading from computers, servers,
iPods, HDD, USB sticks and streaming from the internet - via cable or
wireless - the Audionet DNA will turn any digital music data into a
captivating and emotionally fulfilling musical experience.
Audionet’s DNA, considered a premium choice among elite integrated
amplifiers, allows an ease of use that is uncommon in the high-end audio
world. With intuitive and powerful apps, it interfaces with all tablet PCs and
smart phones, including all members of the Android and iOS operating systems
(Audionet aMM – Audionet Music Manager for Android, Audionet iMM - Audionet
Music Manager for iOS). The Audionet DNA is the first network client, Digital
to Analog converter and power amplifier able to be fully integrated into a
network and operated entirely by a PC or Mac. Our in-house developed software
RCP (Audionet Remote Control Point) allows the user to organize complex
functions and settings effortlessly through a GUI (graphic user interface).The
RS-232 interface allows in addition for professional integration into home
automation systems. At long last it can also be controlled in the classic way
with the Audionet System Remote Control.

The Audionet DNA allows near unlimited options to adjust the music
reproduction, setting a new standard in high quality customizable music
reproduction systems. To accomplish this, we have further enhanced our proven
and acclaimed digital filter technology and integrated it into the DNA. As a
result, the Audionet DNA is the very first stereo power amp that is equipped
with an ultra precise delay, bass, and equalization management, allowing for
very nuanced balance adjustment while preserving the coherence of the music. A
pair of subwoofers may be integrated, which are separately adjustable in all
parameters. Room influences and tonal challenges and problems can be
efficiently corrected. Speaker arrangements can be optimized for every
possible listening situation. Joined with Audionet’s room analysis software,
CARMA, which captures and analyzes the acoustical behavior and properties of
the room, the DNA is now able to perform professional grade room compensation
and correction for the passionate amateur and expert.
Our design goal was to equip the DNA with every conceivable option that real
life applications could ask for, making it the most versatile integrated
amplifier ever built. The DNA is capable of receiving its data from the
Internet- and FM radio, USB Audio interfaces, iPods, HDD, USB-sticks, analogue
sources and can be fitted with a first-class phono preamp. It offers an
excellent A/D converter to digitalise any analogue sources on a high level.
The DNA’s optical link output allows for remote switching of other Audionet
components and it offers a network phase detector and the possibility to be
supplemented with an external power supply.
The Audionet DNA offers universal connectivity. For digital signals we have
provided 10 inputs altogether, from WLAN, LAN to USB and USB Audio to
electrical and optical S/PDIF. For the analogue signals it offers 3 pairs of
gold-plated RCA and 1 pair of gold-plated XLR inputs.

Combining innovative construction and circuit structure solutions with our
experience and knowledge in digital and analogue audio technology, the DNA
utilizes more than 4,000 parts for highest accuracy digital and analogue
signal processing.
Over eighteen years of research and development into improvement of our
components, proprietary software and the feedback of audiophiles at all stages
allow the DNA to feature a sound that is rarely experienced in an integrated
amplifier.

The DNA’s double precision bass management uses 48-bit resolution at all
sampling frequencies, enabling the most accurate reproduction of even the
lowest frequencies. The bass manager offers freely selectable cutoff
frequencies, filter Q factors, and subwoofer phases; thus enabling integration
of up to two subwoofers into the network, and are configurable into multi-room
outputs.

The digital parametric equalizer uses 5 Minimum Phase Equalizers (MPE), for
main channel and subwoofer outputs. Each MPE is configurable in filter type,
frequency, gain, and Q factor within an unusually wide adjustment range,
allowing the effective optimization of all parameters and compensation of less
than ideal room characteristics or acoustical problems. The delay manager
allows for a range of up to 7 meters, automatically calculating delay times in
relationship to the setup and speaker distances while allowing phase control
of each subwoofer.

In order to optimize the D/A conversion, Audionet’s engineers pursued the
uncompromising reduction and elimination of jitter, resulting in a highly
exact, musical and solid sound image, stage and depth. To this end, we have
developed Audionet’s Intelligent Sampling Technology, which performs with
stellar results the analogue signal recovery from the digital bit stream.
Audio data is routed through a two-stage filtering and decoupling procedure.
First, the input data is filtered with Audionet’s proprietary software using
a powerful signal processor and up sampled synchronously, through filters
designed for optimal transient and frequency response. At the next stage, the
optimized data is then resolved through an asynchronous up sampling procedure
at 192kHz/24bit, allowing the complete isolation from any potential jitter
originating from the input clock. The resulting audio data is then passed to
two high-performance converters, which are clocked by dedicated ultra high
precision quartz crystals and individually processed per channel into analogue
signals. This method ensures that jitter faults are eliminated – completely
lossless - in the analogue signal to the highest degree, resulting in
unmatched clarity, room depth, and stage imaging. In addition, power flux
interferences are avoided by powering the digital section of the DNA entirely
separately from the analogue section.

Neither did we make any compromises with the analogue signal processing of the
Audionet DNA. In a lavish research and development phase every detail has been
reconsidered and tested. The circuit design and the construction are designed
for maximum performance.

The DNA’s analogue power amplifier represents the latest version of Audionet’
s state-of-the-art Ultra Linear Amplifier (ULA) technology. This highly
complex circuit topology, designed initially for use in medical engineering
and applications, thus requiring highest precision standards, delivers results
at the limits of physical laws. Even with the most severe strain or amplifier
stress situations, signal impurities are virtually unnoticeable, and high
return loss guarantees that demanding loudspeakers will play to their full
potential.

The amplifier section of the DNA has been designed as a dual mono power
amplifier. This helps to reduce the feedback of magnetic fields and
interference radiation and largely blocks interaction be-tween the amplifier
channels and also the input, correction and power stages. Each channel has its
own power supply with a separate 700 VA transformer and 72,000 µF of filter
capacitance. An ex-tremely fast, local correction stage prevents the emergence
of distortions in realtime. For the analogue biasing voltages we have added
another separate power supply with its own 50 VA transformer.
Audionet researches, pursues and acquires exclusively only highest quality
components worldwide, requiring in many cases custom design and production.
For example, filter caps are designed to our specifications using Japanese
silk dielectrics, custom mica caps, and selected high-current foil caps from
Germany, manufactured for an ultra low loss angle. Internal wiring is done
with top-grade silver/gold alloy, and the best available connection systems
from our colleagues at WTB in Essen, Germany. As part of our quest to use only
the highest-grade components available, Audionet manufactures the DNA’s
operational amplifiers in house. Each Audionet op-amp contains more than 86
discrete components, and is characterized as a unique gain-bandwidth product.

To optimize the high frequency capabilities, the circuits have been
miniaturized, and signal paths minimized. The signal path is clear of passive,
sound effecting components, like coils, inductors, or capacitors. Noise,
distortion, and crosstalk are all but eliminated, for the highest level of
energy, dynamics, and purity of sound. A microprocessor unit regulates all
functions and measurements, including DC, high frequency, overload, and
temperature.
The Audionet DNA’s sound has a strong foundation, is powerful yet spacious
and full of contour, natural and refined, turning bits and bytes into an
unprecedented and vibrant musical experience.
