P.S. it needs one week to produced and tested after purchase
Yulong Sabre D8 is an upgrade version of DA8. They shares similar design and with these upgrades: Two 50W toroidal transformers supply clean powers to Digital and Analogue circuits separately; Full size case which is matching A8 fully balanced headphone amplifier; and lots of through hole components that increased the freedom of sound directed part selection.
Initially we built this machine trying to achieve best possible quality of ess9018 for our own use, so we measured, we listened, we compared, and we tuned it for many years. As result, music flows from this unit effortlessly.
The DA chip is ESS9018, and AD797*5 are used for IV conversion and LPF, then OPA1632*2 for buffer and preamp. Two Nuvotem toroidal transformers supplies the power into LT1129/LT3021 regulations, and quality film caps from Wima, Vishay, Ero and TPC are applied for filtering and decoupling.
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 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.
There is an upgrade available for a even more precise clock and clock power. Please contact before buy should you need this option.
