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!

I don’t know the deep darkest secrets of quantum mechanics and how that effects the covalent bonds of the alloys that make up my car. I am not even sure that is a totally logical statement. I expect the engineers that designed it don’t either. I am quite certain that my capable mechanic knows even less. Whether I or they have this knowledge has no effect on the 0-60 time. Whether I or they have this knowledge will have no effect on measuring the 0-60 time. If I drop a heavy lead ball, it will fall to the ground in a very predictable manner, that I could calculate to a high accuracy if I knew the local gravity coefficient. Well to be honest, I couldn’t calculate it, but I am sure there are others who could. I don’t keep up on the latest research on gravity, but the last time I checked, we didn’t know how gravity works. Imagine that, not knowing how gravity works, but being able to calculate its effects to high precision. Heck I go through my day doing a great number of things correctly without knowing exactly how some things work. No problem though because I know the what. If I do this, I know what will happen. The how is inconsequential. The consequential is what. When someone can take all that how and turn it into a what that matters, I am all ears, literally and figuratively. @reimarc question is looking for a what. All the potential hows in the world don’t make a single what.

@britamerican -

         Better actually READ the original question.

                             EVEN, the TITLE:

What is the SCIENCE behind audiophile fuses?

       Apparently: you've overlooked the fact that the OP didn't change the question*, from 'HOW' to 'WHAT', until the second page (08-22-2022).

       I've very seldom tried to present definitive answers to anything, when it comes to our cables, fuses, interconnects, lifters, but: there exists a plethora of possibilities, presented by the experimentation, theories and developments in the sciences/fields of QED, Physics and electromagnetism.

 * My original question should have been more focused perhaps: "Can anyone in this esteemed forum share  experiences - good or bad - with so-called audiophile fuses?" 

                                To which I also replied.

 

 last time I checked, we didn’t know how gravity works.

I suggest you check again...
