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!

@macg19 ....Ah, but trench warfare is So back in fashion...

...and opening old wounds does allow for the search of infection,and its' byproduct..

Rot. ; )

Objective facts just spoil the mysticism of audioligion....the worship of the bottles filled with fire, the magical wires that lash the boxes of the faithful to the oracles that speak the volumes of the desire to be transported to the isles of Elsewhere.

The 'How' is trampled by the 'Ends'....the 'Means'?

Once again, as so many times before....subject to the Needs....*sigh*

Easily ignored...cost be damned, brushed aside, don't logic me, 'peasant'..
Accompanied by "....if you only knew the Truth, your idylls would fall like the ash of 

Wishbones....*humph*...."

...at the risk of being judged 'harsh'....but, wt....

...but I have a preference for 10' poles.....hard to use as a bat.....and easier to 

Break....

A quote from Sting/Police,

Another suburban family morning
Grandmother screaming at the wall
We have to shout above the din of our Rice Krispies
We can’t hear anything at all
Mother chants her litany of boredom and frustration
But we know all her suicides are fake
 
Threads like this are why I don’t post much on audio forums. They are all the same. The person screaming the loudest is invariably the one with the least knowledge. Words, lots of words. Never shall a salient point be made. A discussion requires addressing specific points and bringing up new salient points. I guess when you only have one tool in your belt, you will use it all the time whether it works or not.
 
Here is a picture of a very cute kitten. It is as relevant to this discussion as most of the links posted. However, it has the advantage that it may make some people smile and it will induce calm.
