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!

Did not notice one bit of sound improvement

This has been my experience, however the swiss digital fuse box was a different story.

I tried 2 different fuses; I won’t name the brand but it was a waste of $300 however I did think the fuse is a bottle neck to a high quality power cable which is why I was willing to try them.

Last week I bought the Swiss Digital Fuse Box. Why? Because the week before I bought the Puron plug in line conditioner (both from Mark at Verfiaudio).

I was so impressed with the Puron and Mark, I trusted his word, and because the solution made sense; replace the thread of wire in the fuse with a solid tube of copper. The SD Fuse Box should kill the “audiophile” fuse business. 

@oddiofyl Give the Swiss Digital Fuse Box a try, but confirm with Mark if he offers no questions asked returns on it...I know he does on the Puron.

I bet you won't return it.

and I sure don’t want to open old wounds and trench warfare.

Then don’t question audiophile ________:)

I need objective facts and not opinions, please.

Wrong forum. Objective facts are tough to come by, because so many questions (and responses) are related to the subjective perception of sound quality.

So, as a scientist, after wading through this thread, I’m curious what your conclusion is, anecdotally of course:)

+1 on the SD fuse box, mine has been in for a week along with the Puron AC conditioner that VeraFi distributes...they work and trying them has zero risk other than shipping fees.
