i can hear huge difference when im changing pads
i can hear tiny difference when im switching cups (left from TH600 or THx00 and keep red right cup from th900)
i CAN'T hear ANY difference when im changing wires
so probably im not that sensitive to silver ions vs copper ions ))
Sounds like you haven't tried the $300 to $500 USB cables yet!
