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?

Everyone should decide for themselves what sounds best in their system. Leaving it to others is like doing art, by committee. The final result won't please anyone.

roberjerman, fuses can have a dramatic affect on sound quality.  i just recently replace the fuse in my Parasound Halo Integrated, and it made more difference than any upgrade to my system in fifty years.  To think they can't improve (or sometimes degrade sound?) is to be blind and naive. Because of the improvement I heard, I replaced the fuse in my Cocktail Audio X45 Pro.  Although not as dramatic of an improvement, it still was very noticeable. 
Fuses are used to prop up the egos of some super human beings on this site who pretend they can hear the difference they make to the sound :-)

In the real world however, they will be very thoroughly investigated by your insurance company if and when you have a fire which may be caused by faulty equipment.

Why the put downs? If he heard nothing so what. It is his money and his experience. If you heard a huge improvement then good for you. Leave it there.
You have to know the motives of Geoffy the fuse troll. He is all about defending his science fiction fuse empire, and his feeble attempts to try to make fun of legit members is how he does it.
