Yulong has many years of experience in ESS9018 design By using audio analyzer and spectrum analyzer for signal
integrity, electromagnetic compatibility and audio performance tests, in combination of newly designed controlling software,
Yulong developed flexible operating, fully functional high performance DAC - SABRE DA8.
The main focus is on adjusting timbre of SABRE DA8. The process of tuning was completed by Yulong's acoustic team
(Based on few experienced audiophiles). The DA8 not only provide large dynamic, but also delicate details. The mid-low is full
and majestic, whereas the mid-high is soft and delicate. Overall, its natural and balanced sound is suitable for various style of
music.
DA8 includes ESS9018 as DAC chip, AD797*5 for voltage reference and low pass filter. OPA1632*2 for buffer and
preamplifier output. Headphone amplifier is base on diamond buffer circuit. ON audio transistor pair output. Also DA8 includes
short circuit protection. The Canadian Plitron high quality transformer, LT1129/LT3021 and WIMA capacitor provide pure power
supply for ESS9018. For analog circuit power supply, Panasonic FC VISHAY BC046 WIMA MKS2 NPO capacitors were
selected to provide outstanding performance and natural listening experience.
USB input uses customized Combo384 chip which co-designed by Italian Amanero and Yulong. It supports DSD and PCM
for formats up to 32Bit/384KHz under Mac OS X, Linux and Windows.
All functions are controlled by software operating system. 2.4 inch color LED display shows the status. Dimming is enabled
after 5 seconds with no operation. The unit automatic saves user settings. User friendly interface provides control for 5 different
filter mode and inverse phase to produce different styles. 80 steps volume adjustment for pre amplifier output to connect to
powered speakers. Under pure DAC mode direct connect to power amplifier provides even better quality sounds. It bypasses
the volume control circuit and turns off the power supply to headphone amplifier to work as a pure DAC.
Multi-stage digital buffer and shaping circuit can optimize the quality of digital signal. Low phase-noise high-precision crystal
oscillator as master clock, bandwidth-auto-set DPLL, switchable jitter eliminator are used to lock and optimized bad signal
before decoding. Signals of high quality can be by-passed to obtain better performance.
Stretch forming aluminum case, thicken material, small size design (250*200*60mm) detailed surface processing. (Size
matches Yulong SABRED series products, e.g. SABREA18 headphone amplifier and SABRE A10 amplifier). Refined aluminum
volume knob, push button and shock absorber feet give smoother fee.
