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!

Well, I have not auditioned or replaced any fuses in any of my systems. I have, however, tried and attest to the positive effects of many of the high-end tweaks out there including some of the products from Synergistic Research. As such, why would well respected companies want to put their reputation on the line if there was nothing to it?

My guess is that there really is something to it, but the explanation is hard to come by. How about trust your ears, we do that with virtually everything else.

@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.

Science can’t prove the earth is older than 6000 years.  You only believe it can.  To think otherwise makes you uncomfortable, I bet.  So many look to science for comfort that dying is an escape from misery, grief and boredom.  So not true.

I have some friends who are fundamentalist Christians ... don’t try to convince them otherwise with science because I know they are happier with their beliefs even though I know it is complete nonsense.

It looks like some of the measurementalists in this group are especially intolerant of religions that are not their own. That is a very bad look.
