How to measure Cable Sonic Differences

For those who think they can measure:

"There are a lot of people who know enough to know they are right, but not enough to know they are wrong"

It's nice to know somebody knows something about transient measurement.  Those who still stuck in the stone age ... errrrrr... I meant getting stuck in frequency distortion measurement., something to learn.
