Should we upgrade high end fuses?

So, the more fuses one changes the more knowledgeable one is? I have changed fuses often on my power amp since I switch from 240v to 120v often and the only difference that I hear is none, let alone an "improvement". I guess I do know something, however, about changing fuses, that is!
I am still waiting for the explanation of direction of current on Alternating Current which makes the direct of the fuse important and audible.

In all honesty, I can't detect any difference either with respect to directionality. But the gold fuses -- in my case, the German "Hi-Fi Tuning" ones -- made quite a difference in my system, despite my initial skepticism. So did simply removing the old ones, cleaning their contact areas, then using Walker SST (silver-bearing grease) on them and replacing them. Dave

Thanks for giving me the benefit of the doubt but I thought this forum was for learning? I may not be as expericenced as some in the world of changing fuses but I would not say I know nothing. All I wanted to know is how can changing a $5 fuse with a $100 fuse make a difference? I'm sure I could have said it better but I must admit that I didn't expect the response I got.

I have a pair of tube amps. I also own a pair of Acoustat X electrostatic speakers. Fuses have burned out on two of these four amps.....saved my house. Don't bypass.

Edkoz, it will make a 95$ difference, maybe less if you happen to install them in the correct direction.
