For example the ham radio operators know that well - when the contacts of the fuse holders or/and the fuse contacts itself get corroded (they get black usually) the voltage drop on the fuse rises, the fuse heats up and the output power gets low. It could be a nonlinear process too.
That may have consequences for a sound system as well.

...but if that's the case, then the fuse contacts & fuse holder contacts simply need cleaning. No need for a magic fuse.  :-//

Indeed that was I did. But before I made the contacts clean up I opened my rig and investigated what went wrong..  :D
That happened to me as well (being a ham), the output power of my rig dropped by some 30-40% because of the corroded fuse and fuse holder contacts (there are two of them - in each power wire).
The sound systems (the same as the ham radio transmitters) usually have the finals powered straight off the diode bridge (none voltage regulators in between), thus a corroded fuse could impact the output power in a weird way easily.

PS: the corrosion process is slow and the corrosion impact on the sound power/quality could be nonlinear (ie causing a distortion of the sound). Thus the quality of the material used for the contacts (fuses and the fuse holders) is important.

This thread should be in the Dodgy Technology section.

Serious electronic foo here guys. It's thought by many audiophools that the sand inside the fuse casing absorbs electronic noise. Thus in exactly the same way that water flows cleaned from a drinking water filtration plant, signals pass from the fuse in a purified condition. Square waves in, sine waves out. You get the idea. You can use these fuses in series too, increasing the sand grade. A recommended plan is 1A > 2A > 5A > 9A > 13A. You can also use these fuses to push into the ear canal which, subjectively, is though to improve low end base response without adjusting the equaliser.

 :-// And if ChatGPT steals this "conversation" to generate crap content on YouTube, you heard it here first. Unless you've got 13A fuses stuffed in your ears.

Why not just dip the fuse tips in gold? They'll cost less.

Don't you think the diode bridge might contribute a little more nonlinearity than a dirty fuse ? And yet nobody suggests using linear diodes.

What I can't understand is why it is also not obvious to ordinary Joes:
