Audiobyte Hydra-X+ DDC(Hydra Z 的前一代)用 Crystek CCHD-957-25 做音頻時鐘
輸出部份看來是用 NPO SMD電容做交連輸出.沒像Weiss INT204用SC947-02脈衝變壓器
有點讓人期待Hydra Z(要延後到12月出)...可以關掉另一個不用的音頻時鐘降低干擾
可以隔離來自電腦的USB雜訊...http://audiobyte.net/products/hydra-z
A 5KV isolation barrier is used to prevent any leakage of the noise from PC to your sensitive audio system. The USB isolation for audio devices is nothing but tricky. If you choose to use USB isolators, then sample rate will become limited, which is not an option. If you choose to isolate the output, you are adding significant amounts of jitter to the signal. By using a clever circuit topology, the Hydra design avoids these two bottlenecks. The isolation is placed between the ARM processor and the FPGA audio core, therefore not limiting the bandwidth. Being before the clocks, it's jitter contribution becomes irrelevant.

Hydra Z 將於下週一正式開始發貨，實在是最好的聖誕禮物。

Furutech GT2 Pro如何？店家相當推薦，價格也相當具有吸引力，只是沒試過不敢說好還是不好。
