Fuses


I’ve read of views on whether amp fuses impart any sound quality or coloring. I had a recent experience that has made me re-think my views (fuses do not affect sound) and wondered if others had a similar experience. 
I have a Line Magnetic integrated amp. After heavy regular use for over 5 years, one day it just wouldn’t power up. After checking the power supply, I assumed it must be a blown fuse. I recalled that Line Magnetic sent with the amp two replacement fuses of the same type/quality that was pre-installed. I dug out one of them from storage, replaced the fuse and the amp powered up normally. 

What surprised and delighted me was the change in sound with the replacement fuse. Fuller bass, more detail and more warmth. I have rolled the tubes several times in the amp, and am attuned to the subtle changes that can make. Popping in a fresh fuse seems to have had a similar affect. And these appear to be cheap fuses, available for a few dollars at most. I don’t think I understand any of this.

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?

Thanks. I know I’m not the sharpest tool in the shed, but I am glad that reference wasn’t confusing just for me. 
Whatever you do, do not ever trust your own ears. Your ears and your brain are liars. Our auditory memory is so horribly awful that no one can ever remember how music sounds. I honestly don’t understand how professional musicians can play or sing the same songs perfectly from memory every single time. It must be voodoo.

I don’t disagree with you at all. My comment was directed to the post that assumes we don’t understand what a fuse does. To me it’s obvious that since the fuse is taking all the voltage then changing it would affect the component.

I honestly don’t understand the damn reference in relation to the fuse. The fuse isn’t holding back anything.
