To Fuse or Not to Fuse... That is the question!

Thank you Again! That is what I originally thought you said! 

No fuse is always better one less bottle neck ,but doing so 
you take away fault protection from possibly saving a circuit.
just buy a premium fuse  slightly bigger ,for a stock fuse can vary
up to 15%. 

OK, I am totally confused. You guys saying you use these fuses in AC circuits?

From their web site:
A: Yes, fuses are directional.  Electricity should flow from the left to the right when you view the fuse.  If you do not know the direction of flow you should listen to the fuse inserted in both directions.  One direction will sound more detailed.  This is the correct way.

I thought AC changed directions 60 times a second?

   WOW. This subject has been tossed around these forums and, every once in a while, it resurfaces. So many opinions about fuses, wire, and everything else.
   My neighbor builds a deck exactly like mine. But, he stains it differently. Same deck. He likes his and I like mine. Nobody can convince you that what he does is better than what you have done as long as you've convinced yourself you have done better.
   So many "scientists" on these forums. Take note of the response just before mine! If I pleaded with my wife to agree to the expense of an audio upgrade, whether beneficial or not, she would agree that it was a good choice to make me happy with my decision.
  There's no end to this discussion.
