1. HDMI native DSD interface
HDMI interface could support both 1080p video and 8-
channel high definition digital audio with bandwidth as high
as 18Gbps. The Native 12S and DSD digital audio internal
bus are built in the main internal bus of the HDMI interface,
making audio transport without any format conversion. It
could transmit 8-channel of PCM audio with 24bit 192Khz
directly and DSD native audio stream with 1bit 5.6Mbps.
The decoding process is that HDMI native DSD bus
interface could transport the DSD original format audio
stream received from the output of SACD or blue ray SACD
HDMI interface to DSD internal bus of ESS9018 chip
without any format conversion process, which realizes an
authentic DSD native data decoding directly and ensures
the 100% realistic reproduction of music.
2.Based on the Latest Xmos DSD Solution
Another biggest feature is that the latest Xmos is equipped
with built-in DCA , which not only supports Native DSD data
transportation provided by USB Audio Class 2.0 but also be
compatible with the current common DSD mode of Dop
mode. The Xmos USB core technology could input Native
D S D d a t a w h i c h i s u p t o 3 2 - b i t / 3 8 4 k H z P C M ,
DSD64/2.8Mhz, DSD128/5.6Mhz and DSD256/11.2Mhz to
the USB audio interface. Except for the traditional PCM
digital stream, it supports all popular PC digital audio
format but also the decoding for the native stream of DXD
and DSD.
3. Dual ESS9018 DAC design with 8-channel parallel
mono output mode
Audio decoding is powered by 2 groups of ESSSabre
ESS9018 chip with patented technology of 32 bit”Time
Domain”eliminate jitter clock, and digital audio data is
c o m p l e t e l y a v a i l a b l e f o r P C M u p t o
32bit/384kHz,DSD64/DSD128 and DSD256 by Xmos USB
interface. As a result, it could be compatible with those high
resolution format without any further upgrade. At the same
t i m e , i t i s e q u i p p e d w i t h a T C X O ( Te m p e r a t u r e
Compensated Crystal Oscillato) with ultra high accuracy as
little as 1ppm so that the high dynamic high contrast
characteristic of high resolution digital audio could be
perfectly remain. You could enjoy an unprecedented
experience even though playing the compressed audio like
MP3.
4.Pure analogue power design
The power system of digital circuits and analogue circuits
are separated that ensures the pure and accurate
reproduction. Digital part is totally isolated from analogue
parts from power to circuit board, and the internal cables
are as less as possible so as to reduce the interfere with the
sound. The circuit board design use the quality sound as a
starting point with sophisticated materials.
The apparatus has a built-in authentic hi-end analogue
preamplifier featuring with a finely tuned DAC which could
set a proper level balanced XLR output to amplifier. The
preamplifier part has a built-in Pre out output interface so
as to connect the external audio equipment. The output of
single-ended signal is provided by high quality bandwidth
and ultra CMRR transformer, being completely consistent
with the sound from the XLR output and providing a more
suitable sound for the audiophile within the sound
characteristic of big dynamic, high density and vigorous.
5. Floating design
The floating designed DAC has a instrument level single-
ended output module(audio coupling transformer) with
CMRR up to 90dB and bandwidth up to 22Mhz. It could
provide large dynamic and wide bandwidth audio single-
ended output with reduction rate of 100% symmetric
int erf a ce, m aki n g t h e sou nd m ore l i ste nab l e a n d
interesting. Audiophiles could enjoy the high quality sound
from symmetric interface by the single-ended output.
Product description
6.Ultra-low distortion with high precision balanced
analog volume potentiometer
The output volume from the traditional DAC decoder
which supports high level pre amplifier output is adjusted
by DAC chip digital attenuator, however, we chose
balanced analog amplified volume attenuation system
modules , as a result, linear regulation could be accurate to
0.5db per step, making the volume control more smoothly
without any distortion and noise from the traditional
potentiometer.
Model one could be used as a preamplifier as the DAC
symmetric output level could be up to 2.7v rms and the non
symmetric one could be up to 1.2v rms. A pure analog
symmetric high precision potentiometer is designed at the
output, which could control the output volume level more
precise with 0.5db per step from 90db to 0db. The analogue
symmetric audio signal outputs directly via symmetric level
adjustment so as to realize the control to the preamplifier
output volume which is convenient for connecting dual
amplifier or high quality active subwoofer.
7. The heavy weight double sandwich chassis design
The ultra-thick combined sandwich chassis is made by
mixed material with a design of unique suspension and
shock-absorbing technology. The customized shock-
absorbing material is sandwiched between steel casing and
thick aluminum alloy chassis base, which could eliminate
the bad effect of vibration to the sound subtly with the large
bronze spikes and realize a perfect suspension. The effect
of perfectly isolating from the interference of the external
vibration and eliminating the mechanical resonance itself is
far more than a common so-called heavy weight materials
designed with single material.
The internal circuit boards and components are all coated
by shock abortion material, which could completely
eliminate the effects of subtle vibrations due to the voltage
and current that generated by working component to the
sound, as a result it could significantly increased the
cleanliness and fluency of the sound. All the electronic
components are working in exactly the same temperature
due to the hermetic chassis, which prevents the component
and circuits from being corroded by dust and moisture, thus
increasing the service life.
8. Fully balanced high-speed analog amplifier circuit
The available bandwidth of the apparatus could reach to
650 kHz in (-3dB) and ensure the flat of the frequency
response within listening range, which can perfectly
reproduce the high resolution files and the essence of high-
contrast and high bandwidth for the new generation
recording. Not only ensures the available wide bandwidth
but it also allows the rotation rate to reach to excellent as
85Vus(p-p), and the result is that the reproduction details
will not be dragged and fuzzy, like accurately focusing a
high resolution pictures. Thanks to the selective transistor,
the High power could coexist with low distortion, and there
is absolutely no roughness like the normal transistor. The
paired transistors are working in the environment of the
same temperature and low vibration due to the built-in non
reso n a nce the r m al d e s ign and fur t h er t h e m u sic
reproduction perfectly .The key to make the music alive and
rich is that the full range has a very low distortion while full
power output.
