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!

@mapman ”…device whose job is in fact to burn up and destroy itself when needed…”.

 

Well, yeah, but, in my fifty years of being an audiophile I have never had a fuse blow. I would imagine that is not an unusual experience.

Same here but not 50 years… never had a power plug outlet fuse blow.  Risk is very low and not really needed…give me those Sluggo’s instead and save 💰

I got a refund for the fuses.

You know, what mapman says about fuses could also be said for vacuum tubes or even a fine meal.  Anyone see the cost of WE 300b tubes these days?  

The front end of my stereo system has a total of 22 tubes.  I’m not bragging, I’m just pointing out that the nature of this hobby is expense- both the upfront costs, the depreciation and the recurring costs (electricity, tube replacement, subscription costs, repairs, etc) must be considered.  To denigrate the use of expensive, handmade fuses is saying that the entire hobby is futile. 

When I was a kid I remember people putting pennies in their fuse boxes....

I remember my parents doing that
