ccscho hing,
sorry for late reply. I am using HK$20 grade USB2.0 cable, the sound is neutral and got no compatibility problem at all.
Yes, USB2.0 specification maximum speed is 480mbps , normally, when we use a external SSD harddisk and connect it to USB2.0 port , it is NOT easy to transfer data at 50~ 60MB/sec , if we can transfer data at USB2.0 at 480Mbps , 1GByte will takes around 20 second for transfer.
Many computer machine terminated cable can support up to 80% of its specification in maximum, the usb 2.0 cable need to be around 105 Ohm to 110 Ohm in impedance.
cheers!
