USB, coaxial 定係 optical 最好聲?

alexkcso

I think V-Link is a special case - MF recommends to use toslink in order to totally separate CAS from Amp.  Some web reviews suggested that V-Link output does not has its own pulse generation, that's why.

Anyway, in general, most reviews recommend coaxial over toslink.  My own experience of using V-Link is toslink sounds less "dynamic" than coaxial, and V-Link does make M1DAC sounds more "stable" (comparing with USB input)

    Not sure about Hong Kong, but it's definitely available in the US and the UK...

從數據傳輸上，點解會有分別呢? 如果音質上有分別，即係話數據傳送上有遺失，令到個dac處理上出現問題? 有冇方法可以做到測試?

其實點解光纖差過同軸線呢，主要因為有關光既傳送，當光傳送既時候，會造成反射同折射，如果光由訊源可以100%全反射至接收，就最PERFECT勒，但有時因為種種因素，例如: 線材裡面既反射物料, 線材屈曲等，而做成折射，即係話佢係線材裡面反射一次，可能只有70%左右反射，而30%係LOST左，而一條接近100%全內反射既線材係好貴既，市面上一千幾百個d，算把啦，買條同軸線好過啦..................

    Thanks! 不過都覺得有點奇怪，如果data loss係失真的理由，點解咁多間廠商做部機時唔做多個verification功能，確保無數據遺失?雖然好多網上說法都講數據會遺失，但我始終找不到較為科學性的測試報告，令我較難相信，因為在電腦上，用條最cheap的cable,傳送100mb的數據，接收一定係100mb,最簡單係用zip file做測試有數據遺失應該解壓唔到，同埋實在太多話數據遺失的說法在音響上出現，其他媒體又唔係太見，如果線材會影響數據，按理金融界應該會用最貴的線做傳送，我實在太多疑團，好想找出答案，唔想去到影音店，胡亂相信sales的吹嘘。

Andycgankk兄，我都有你同一個疑問。data is digital - only 0/1, that means right or wrong. If data loss by transmit, file must be damage. Like image file, if data missing/damage, file cannot be opened.
