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

good fuse-holders are generally copper alloy, silver plated in many cases, are available.

Non magnetic direct plating, in some. (no magnetic intermediary plating, ie nickel based)

Eaton and Littlefuse makes some beryllium copper silver plated fuseholders. Just a quick search away..at digikey, for example.

Acme Audio fuse holders, which I used to have back when I had fuses, are not only silver plated but cryo’d. Fuses should also be cryo’d for best results. Everything should be cryo’d. Almost all high end cable manufacturers routinely Cryo their cables. You have to if you want to compete in the marketplace.
