Next time you are with your friend, have him point out the sonic differences between a pair of cables. It's a learning process to recognize / observe the differences that can exist.
There's often much discussion that cables do not and can not make a difference. I find that as a system becomes more resolving, many cables out there can cause serious destruction of the system's magical capabilities. But this comes years after learning the subtle differences that once you become familiar with, are no longer subtle.
