其實簡單一句，唔想大家買錯野，唔會玩獨立供電，亦自然無需要雙頭線，因為平日響舖頭實在太多人問我點解雙 ...

其實我諗問你雙頭無網上講咁好果D人, 好應該買一條過的... 因為佢地唔識用雙頭線, 或者好似史力加咁講, 唔想知點用. (http://www.hiendy.com/hififorum/ ... 867&pid=1630042)

或者如果你有賣雙頭線, 你賣之前買好等買果個知道點用先買, 唔係買左出唔到應有表現, 以為你呃佢錢.

呢個就係同雙頭線默認嘅 system config 有關，因為其實個 connection 實際唔係要個 +5V，而係要個地。

基本上Wilmer大師設計的USB線+地盒...是我目前為止見到最完整的解決方案,先落地去雜訊的實踐很優。讚!
我在想Zonotone那頂級的USB線也有外接地,但看結構好像沒有和USB內部的GND相連,不知效果好不好?太貴不太想試試。但我會用你的idea做一條USB線並從GND連出來的小Y插線直插DAC機殼,看效果有沒有比一般USB線來的好。
此外,若DAC內部供電是否就不用再外接一個5V(whatever,電池或LPS)?

咁樣另外接地未必 work，要試，因為有可能引起 ground loop，到時仲大干擾

係，只要係 DAC 內供電，就唔洗再比電

小弟有小小意見

今次的測試並不能/不是反映單頭,雙頭Usb cable的優劣.
先撇開主角black cat cable,只睇中間兩條分別為單頭blue jacket,雙頭metal head.
當日測試上的結果係各有千秋,只計點數兩者可以話係同分.
所以我對單頭一定好的講法會有所保留

sorry,  may be my explanation is NOT long enough.

I use the dual head (Y Shape) cable with both head connect the USB controller card,  and the Adnaco system is connect to Linear PSU only. the USB controller is powered with Linear PSU purely.  The Adnaco master side (the Mother board,  CPU and SSD is powered by Linear PSUs separately normally.

so,  the USB cable (no matter dual head or single head) ,  they will ONLY connect to Linear PSU.

When I tried Y shape USB cable last year,  I already using Adnaco Pcie extension system with Linear PSU for the Adnaco client side.

For Y shape USB cable,  I tried to use battery power and compare with Adnaco with Linear PSU last year also , Battery (japan brand or Hong kong brand one). The Battery powered config is EVEN worse than connect to my Adnaco client system with linear system,  the treble does not sound lively and when I hear orchestra base music,  the battery powered sound stage is narrowed than connected to my PSU.

So,  we did not try to use battery power this time with Y shape cable ,  as in the Adnaco system with Linear PSU,  Y Shape USB cable is powered with Linear PSU already , so do single head one.

Therefore,  for both Single head USB or Y Shape USB cable,  they are both connected with the same Linear PSU's 5VDC output.  No one got advantage over power supply.

This is how we test all the above cables this time.  and here is the background informaton ,  if any of you need to ask for more informaton, just let me know .  I can explain as detail I can.

For Adnaco PCIe extension system,  we can visit www.adnaco.com .

Regards,
Blau

你誤會左，冇人要求亦冇人講過咩爆料唔爆料，前面講係 sales 點去 present 件產品，有冇比客人先清楚了解件產品，完全同你講嘅咩有讚冇彈就要爆料毫不相關
