标题: YULONG Audio 旗舰 D8解码
SABRE D8在电路结构和大受好评的DA8上大致相同,D8和DA8相比进一步加强了电源,使用两只50W的环牛对数字/模拟电路分开供电。全尺寸大体积的机箱可以和A8全分立平衡耳放搭配,使用大体积发烧元器件,经历数年反复的长时间聆听对比调试,D8拥有宽松自然流畅的听感。

SABRE D8使用ESS9018为解码芯片, AD797*5电压基准和低通滤波, OPA1632*2缓冲兼前级放大输出,两只Nuvotem环牛供电, LT1129/LT3021等精密稳压,Wima Vishay ERO TPC等大量薄膜电容做退耦和滤波。

USB输入使用和意大利Amanero合作开发的定制版Combo384,支持DSD和PCM 32Bit,384KHZ,支持Mac OSX Linux, windows操作系统,有良好系统兼容性.

功能的操作使用软件控制 , 2.4寸彩色液晶显示屏显示工作状态,5秒无操作时亮度降低80%,自动记忆用户设置, 简单易用的操作. 5种滤波器模式和正负相位可调能组合出各种不同风格的声音., 80级可调音量前级输出可以方便的连接专业有源音箱,纯解码模式下外接功放效果更好,它关闭音量控制,完全工作在纯解码状态.

多级的数字信号整型缓冲电路,能充分优化数字信号质量,使用低相位噪声高精度晶振做为主时钟, DPLL锁定带宽自动设置, 抖动消除器可以开关控制,让它既可以锁定劣质的音频信号优化后解码,也可以让高质量的信号直通输入得到更好的声音.

预留的可升级高精度晶振电源以及接口,方便升级晶振(详情请购买时咨询)
本机有30个额外购买的高精度时钟,时钟是限量的,用完以后就再没有了,需另加2000块钱,购买前请注明,使用高精度时钟模块前,需要热机20分钟等时钟到达稳定状态后再用


Saber 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.

Before using ,it's better to warm up for at least 20 minutes. precise clock needs to warm up stable
