這隻提到這點
high-speed photocouplers for Galvanic and magnetic isolation between Digital stage and Analog DAC ground以光耦合傳導訊號避開地線雜訊,這就對啦~
Jitter free digital interface AQlink (I2S protocol)嗯...I2S與jitter free沒啥關係,該說,若以DAC IC為clock master,那I2S就不會吃到由前端來的jitter。
Transformer current / voltage conversion這不知道有啥好處...若是以體積來看,線路越大,越容易受干擾,額外引入的RLC也越多...
Zero S/PDIF Jitter design, digital receiver stage PLL (phase locked loop) technology這又不知是用哪種手法,Lavry那招?
MOSFET Virtual battery circuit for analog anode supply這不知是啥...
Regulated DC filament supplies嘿嘿...老一輩可是有一堆人堅持要AC點燈絲啊...
Fully discrete analog stage, not even a single Op-Amp is used哈哈,這個踢了Asus的屁股
主電源(右上角那群電容)看來還好,並不特別強;
右下角最上面那片該是USB介面板,二個銀色的石英震盪子旁邊很單薄,嗯...
左邊類比電路的電源倒是充足很多,嗯...又是類比派的...
四顆DAC IC不知在何處,似乎是右下最下面...左邊那二個銀色的鐵盒或許是變壓器,I/V轉換在這做?那photocoupler在哪呢?訊號怎麼走的?
