So done with audiophile fuses

The journey started with a medium priced ($50) fuse in my power supply.  A failed rectifier tube blew that one out.  Not a fuse problem.  Next up was a blue fuse in my pre amp.  It blew and was not caused by a pre amp problem.  Apparently they sometimes are more sensitive and it was replaced by an orange fuse two values higher.  Things were going along fine.  I replaced the pre amp with a newer version of the pre amp and it has the same fuse value.  Five months latter (today) I turn on the pre amp and nothing.  it's a five month old pre amp so I suspected that it was the fuse.  Sure enough, I replaced it with a ceramic Littelfuse of the lower correct value it works fine.  No more wasting my money on unstable fuses for me.

Let's get this straight. Pure and simple; a fuse is there to stop drawing more current that is desirable.

How can a fuse ever be better than the wire into the holder and and the wire out? It's a physical impossibility and it's all in the mind y'know.

Even when the fuse holder is soldered onto a circuit board, it can't be better than the material used for PCB. It's a physical impossibility and it's all in the mind y'know.
