Some say "the mark around his nipples is exactly the same shape as the nurburgring"
Meaning, I have never paid for an "upgraded" usb cable (but I'm sure some people will be shouting out to educate me) but the power supply definitely helped. Amazon search Pyramid PS3KX 3amp power supply.
In my opinion, I wouldn't upgrade the usb cable, Power supply and interconnects deserve priority if you are looking to upgrade the signal path to and from your Dac.
