The DAC solution of the SABRE D18 we used is the 32-bit audio DAC
ESS9018 which represents the highest performace in the world.(With ESS patented
32-bit HyperstreamTM DAC architecture and Time Domain Jitter Eliminator, the
SABRE32 Reference Stereo DAC delivers an unprecedented DNR of up to 135dB and
THD+N of -120dB, the industry’s highest performance level that will satisfy the
most demanding audio enthusiasts.)
After a long time of the R&D
regardless of the investment cost,Yulong Audio worked out the product with high
performace and good sense of hearing which uses the ESS9018 as the main controll
The SABRE D18 uses the high-performance transformer with low
magnetic flux leakage whose brand is PLITRON from Canada as the driving force.
The DAC digital signal circuit uses the extremly low-noise power through the
multiple groups of the secondary voltage-stabilizing.The DAC analog circuit uses
the high-speed and precise servo voltage-stabilized source.The IV conversion
uses the expensive,precise and high-performance op-amp AD8620.The filter
processing of LPF uses the expensive,precise and high-performance op-amp
AD797.The precise risistances with military specification use the DALE.The film
capacitors with multipe specifications use the WIMA.They are selected to match
to be used in the LPF.The TPC film capacitor is used as the decoupling and the
Panasonic FC electrolytic capacitor is used as the power filtering.
benchmark source crystal that is used to eliminate the clok jitter is customized
by the crystals manufacturer and its phase noise is very low.In order to achieve
the best performance and good sense of hearing,the PCB has been tested for many
times to optimize the layout.For example,to obtain the best signal quality,the
layout of the digital signal transmission is not directly placed in the PCB, the
transmission line of the SMA interface is used as the transmission.
SABRE D18 has a small size(250*190*50mm).The shell of the SABRE D18 uses the
aluminium alloy mould to stretch the forming and the thicken material.It uses
the fine surface treatment technology.(The volume of the SABRE D18 is suitable
and compatible with the other SABRED products made by Yulong Audio,such as the
headphone amplifier SABRED A18 and the power amplifier SABRED A10.)
material selected is nothing but an assurance of the quality,the debugging and
designment of the circuit can finally represent the essential of the high
quality.The designment of the SABRE D18 is based on our rich experience of the
DAC development. With the help of the digital audio analyzer,Universal
Table,Spectrum Analyzer,Broadband oscilloscope,and the other equipments,we can
analyze the basic performance index of the SABRE D18,debug the reference voltage
,analyze the digital signal and measure the electromagnetic compatibility .After
a long time of debugging,we believe that the SABRE D18 can play close to the
limit performance of the ESS9018.
The data is just data, it comes from a
soulless machine which has no idea on music In order to move from the cold solid
data to touching music playback, we must make acoustical adjustment through
hearing test, using the sense of our experience.
Yulong Audio has its own
acoustical tuning team that is made up of acoustic engineers, senior audio
fanciers and experienced music lovers. With their extensive listening tests and
fine tunes, the SABRE D18 is able to play back music with rich emotional
elements and graceful charm, give an elegant listening
Although the SABRE D18 has an extremely extended high
frequency response, the voice is no where from harsh but soft and delicate.
Combine with it’s full and vivid mid range, and well managed bass, the playback
is well-balanced, natural and smooth, it gives the evidence that SABRE D18 is a
high-performance DAC with an extreme pleasure of listening.
Please make sure the voltage selector is set to proper position that can match
the actual power supply voltage. Otherwise this DAC might be permanently
damaged! Under such circumstance, the warranty is void.
