假設個DAC 有USB,同軸2種INPUT
用XMOS異步USB數字界面同軸入DAC
定用iusbpower USB入DAC 會好D
iusbpower 有測試CHART  可以去到-140 DBV
XMOS異步USB數字界面 可以去到幾多?

有無人對比過
邊個出黎個背景靜D

I use ifi iusb > ifi ilink(xmos to coaxial) > dac

My dac is mytek which have usb connector.

I found most usb dac , usb chip will affect by internal power supply and fuse.

Although many people will say, it increase jitter.

But I found it is more analog.

要視乎個別 DAC 的設計。

如果個 USB DAC 係用自己o既電源，你加個 iUSBPower 都無用。
如果個 USB DAC 靠 USB 供電，咁個 iUSBPower 就會有用。
