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

Almarg, Roger appears to be just another outspoken but deluded amp manufacturer. Do you have a better example? 😬 Besides, you should know better than to use an Appeal to Authority. Does that work in court?
Geoff, I wasn’t using an appeal to authority in my previous post (although I would consider such an appeal to simply be inconclusive, rather than being illogical as you’ve often asserted). I was referring to specific technical points and analyses that have been presented here, which stand on their own regardless of who has presented them. And as it happens some of them were presented by me, as I mentioned.

For just a couple of examples, among many that could be cited:

I’m bound to regret this, but just can’t resist. So, on one side we have Ralph Karsten and Roger Modjeski (as well as almarg and other posters here)---two of the best living audio engineers in the world (I obviously place value in "authority"), and on the other side those who claim fuses are directional. And the explanation for Ralph and Roger (and perhaps Al, etc.) disputing the even possibility of fuses being directional (AC being what it is) is that they are "deluded amp manufacturer(s)"? Ay carumba! Very fitting in these Trumpian days.

I guess the designs of those two engineers sounding as good as they do it just plain ol' fortuitous luck. not because they know and understand what factors in electronic design lead to good sound. Thankfully we have some non-deluded audiophiles, not blinded to empirical findings by their knowledge and "beliefs", to keep hi-fi progress moving in the right direction.

@bdp24  don't resist the need to voice your concerns and beliefs. This is what forums are for. 

Trumpian?

Totally agree. They refuse to defuse but choose to infuse an effusive obfuscation instead. Obfusely everyone knows a fuse when flipped around is an esuf which sounds different. Now you can't argue that
