What are fuses used for?


I have, I’m sure to many, a very dumb question. I keep reading about fuses.  I have a fairly sophisticated system and have never come across the need for a fuse.
Can someone tell me where these fuses go and what they’re used for?

The naysayers must be studying the script of 12 Angry Men. “You can’t prove it!” “But you said we can forget about all the other stuff.” “How can be be so sure?! “I’m telling you, some of you people in here must be out of your minds.” “Don't give me that. I'm sick and tired of facts! You can twist 'em anyway you like, you know what I mean?”

I was merely pointing out that if audiophile fuses do anything at all the effects would be super easy to measure at the fuse itself.

>>>>Isn’t it nice to think so, Eric? The name is Geoff, by the way, not George. It’s probably best if you don’t do the test after all. 😀
Great idea. Why don’t you do it and report your findings? Are you waiting for someone else to do it?
Glubson, just curious, did you forget to take your smart pills this morning?
Did somebody forget to set out the roach motels last over the holiday? 🏨
Oh, they got their PhD in two years? Wow! They must have very large heads.
What I glean from your post is that fourth grade was a watershed year in your development. 👦
Wolf, we all know acoustic engineering school is a scam. They don’t teach anything to prepare you for high end audio. They don’t even teach engineering. Give me a break. They teach you how to be a knob turner and wire puller. Though, on the plus side, being all thumbs might actually be good for knob turning. You should run down with great haste to whatever two-year podunk school you went to and demand your money back. No offense.
Whoa! What? Why the put downs? Hey, phillyb, no offense but I’m afraid you’re not following. Wolfie is claiming everyone who hears the fuse is crazy. And he’s the only sane one because he can’t hear the fuse. Capish? If that ain’t a freakin Catch 22 I don’t know what is!
OK, Wolfie, I’ll give you that - they didn’t work for you. So it’s what, you against 40,000? The smart money is on the 40,000, not some pro audio layabout. 
I almost forgot. Fuses are also used to torture naysayers. That’s the most fun feature of fuses as we have seen.  Fun for everyone! 
Fuses can be used to change or control the sound just like speaker cables, interconnects, capacitors, power cords or any wire or cable. Capacitors serve a function just like fuses. Yet capacitors are also directional due to the wire running through them. Since all wire is directional, including the teeny tiny fuse element, all cables, capacitors, fuses sound better in one direction vs the other direction. In one direction, that usually cannot be predicted by the user, the sound will be relatively more coherent, more natural and more musical than the other direction.

This proposition regarding directional can be illustrated most easily by reversing the direction of interconnects and evaluating which direction sounds better. Voila! I’m not referring to shielded interconnects, since they have their own independent issue regarding direction.
