I think Geoff is trying to say that since your experience lies outside of (an outlier) than what he believes is typical, it should be discounted. At least by anyone else. It's a way of dismissing a data point that is at variance with your hypothesis without having to explain the divergent data. It could be the result of an equipment failure, operator error, or a faulty hypothesis. In the case of something as subjective as hearing a difference between line fuses, I'm not sure where it gets you. If the listener thinks the fuses improve his experience and wants to use "audiophile grade" fuses, or magic dots, or little pieces of tin foil on his CDs, god bless.
