Update 2 : still no change after burn in. Now im using the usb cable in my headphone setup. In my headphone setup (centrance dacmini - wooaudio wa2 - beyer t1), the usb cables makes 0 difference to the standard usb. However, in my main system, the usb brings negative impact to the sound compared to the standard usb.
In conclusion, in "my" system, and imho, 1) usb can make a difference 2) usb burn in is bollocks.
Cheers all
When USB cables make a sound difference, this is only a mask of the real issue, which is both that the source is noisy—quite normal with computers—, and that the DAC doesn't provide the necessary isolation.
In my opinion Nad doesn't do the best USB implementations. Many people seem to use the M51 with USB-to-SPDIF converters to work around this.
