If one was to run a fuse, any of the types of fuses here in this thread being speculated on..any fuse of that size/type...under complex loads, through a complex set of distortion measurements on a audio precision system , lets say, an SYS-2722...and run a whole plethora of tests, on a hundred different fuses..a pattern of distortion measurements would be the result.
high order odd harmonic distortions.
The human ear is VERY sensitive to odd order harmonic distortion.
Again, this is the distortion pattern a fuse exhibits under the highly dynamic load that a piece of audio equipment puts the fuse under.
It is so well known, so well documented in the realm of expected fuse behavior... that an engineer of fuses and an engineer of audio equipment would look at you like you had three illiterate heads if you asked a question of it being measurable or noticeable in it’s effect on an audio amplifier.
Fuses, under dynamic loading conditions, exhibit high order odd harmonic distortion in how they deal with the current and voltage load.
the end.
High end audio fuses, do their best to eliminate or negate those expected distortions as much as is possible, so they are less audible.
I don’t buy high end fuses myself, I go for long time lag fuses (10kA flash break point), non magnetic ones with ceramic bodies, and that is as close as I can get to an expensive audiophile fuse with a custom designed filament, but... for about $3-5 each. This is the most linear distorting fuse you can get to without going ’audiophile’ and expensive. I’d even wager that the fuses that are cheap in the audio world, might just be made by these given companies like cooper-bussman, schurter (germany), SOC of Japan, and so on.
I can do this myself, but don’t recommend that others do it without research, as you can’t just stick any fuse in a socket, as you can easily invalidate the warranty and the safety of the device. No random fuse changes, just cause it sounds better.
