Fuses fuses fuses


Ok, this is about fuses

1- a standard Bussman fuse is UL approved. Are any "high end" fuses UL approved?

2- do any component manufacturers supply their gear with any of the usual suspects of high end fuses as opposed to a standard Bussman?

3- let's say fuses do make a difference. Given incoming power is AC, why could fuses be directional? 

Not meaning to light any fires here- 

thanks in advance

"Terry9 I can tell you that the upgrade fuses are clearly effective in my system. However you’d likely remain skeptical based on your own inherent bias and preformed opinion."

Please re-read my earlier post, "I think it is possible that exotic fuses sound different" (2017/070/09/6:15 PM).

"OK, so if it would be "very easy to test" how come none of you guys ever bother to test it? Talk is cheap."

Because I'm not making an assertion which goes against established physics. You are. The onus of proof is on you.

>>>I'll be the judge of that.

The onus of proof is on you.

>>>No, it's not. That's a very common misconception.


While stuck in traffic on the LIE this morning, I was wondering if there is any material or compound you could use to insure complete contact between a fuse and fuse holder? 
I guess you could solder it in, but reversing it would be a hassle.
