根本同軸或光纖數碼線就冇可能傳輸到 DSD 訊號, HDMI 1.2 至開始能傳輸到 DSD....
另外少少 DSD 知資:   

The I2S and DSD are clocked data streams, ...

因為DSD係clocked data streams，所以如果部SACD機同部AV Amp機嘅鐘唔同，各有各行，出嚟嘅效果一定有好大影響，所以要兩個鐘永遠都同步一齊行，SACD機個鐘要跟著AV Amp機個鐘走，兩個鐘要手牽手，AV Amp機嗰個做主人(Master)而SACD機嗰個跟，就可同步走。



Sony嘅H.A.T.S.就係咁樣運作：  

HATS addresses the problems of simultaneously communicating six channels of digital data at 2.8224MHz, which would otherwise result in timing (jitter) errors.

HATS uses an algorithm that rejoices under the title of 'command-based rate control of isochronous data flow' and includes variable speed transmission from the player and a buffer memory in the receiver, an arrangement mediated by a command signal which controls transmission speed, so that jitter performance defaults to the inherent accuracy of the receiver and player master clocks.

No separate clock connection is required and HATS is unresponsive to the marginally different clock rates you can expect to find in the player and the receiver, which are typically a few tens of ppm (parts per million). An earlier version of HATS was available on the 9000, but using iLink rather than HDMI.

Even with HATS, the HDMI output is still compatible with the HDMI inputs on other equipment. But full-on DSD with HATS requires a compatible receiver/decoder, such as is fitted to the Sony STR-DA5500ES. The lower-end Sony STR-DA2400 decimates DSD to linear PCM which, if Sony's word is to be taken as read, must be at the cost of ultimate fidelity.
