What is the science behind audiophile fuses?


There were many threads on the topic of "audiophile fuses" on this forum, and I sure don't want to open old wounds and trench warfare. The fuse on my preamp blew suddenly two days ago, which prompted me to search for a replacement. That's when I came across the term "audiophile fuse" and the fact that they demand far-out prices. Deeper curiosity brought me to several other fora, where users posted glowing praises about their Zero fuses and other exotica. Now I am a scientist, but not a physicist or electrical engineer: so please enlighten me! How can a fuse have an audible influence on the signal, when the signal does not even pass through it? How can a fuse be "directional" when it deals with alternate current? I mean, if I recall my university physics, a fuse is basically a safety valve and nothing more. Am I completely missing an important point here? My scientific field is drug discovery, and because of this background I am thoroughly familiar with the power and reality of the placebo effect. I that's what I am seeing here, or is it real physics? I need objective facts and not opinions, please. I really appreciate your help!

Here's a fun trick. Wrap a few turns of masking tape or PTFE tape around the glass part of a fuse making sure not to touch the end caps. Leave say, a 1mm space. 

Do a before and after test. 

@johnfritter Interesting. I can't really imagine that combination of parts sounding good at all. 

@reimarc The power supply doesn’t merely allow proper operation, it is that which is the source of the actual music. Simply put, the amplifier circuitry modulates the flow of that power through the speakers. Ceteris paribus, the better the power supply, the better the sound.

not the signal circuit itself but the part that supplies the power for proper operation.

@1extreme Think that's bad? I heard of folks who believe that some invisible deity controls the entire universe. And if you don't talk to it in your mind, you may burn forever. 

...who will look me in the eye and tell me they believe the earth is only 6,000 years old.

So, anti-vibration damping? 2c for $49?
