I thought a fuse was a sacrificial safety device that melts during an
overcurrent condition to protect an electrical circuit. So isn’t the
role of a fuse to melt if there is too much current in order to protect
an electrical circuit/device?
Correct. And you must have missed my earlier post explaining this. Ordinary fuses are designed to one spec, the current rating at which they melt and blow. They are not designed to perform perfectly linear or in any way at all really, at anything less than this. They are made to blow and nothing else.
All wires, the more current the hotter they get. The hotter they get the more resistance increases. This is in effect a volume control, one where every dynamic peak increases current draw, which increases resistance, which turns down the volume. Ordinary fuses are in effect turning down the volume on transient peaks all the time. When you hear people saying the audiophile fuse sounds cleaner clearer more extended and dynamic this is all very easy to understand once you know about wires and resistance.
Because unlike cheap fuses designed only to blow audiophile fuses are designed to perform with high sound quality all the way up to blowing.
Pretty easy to understand, right?
