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, let me give you a little logic lesson if I can be so bold. Just because there are a lot of variables doesn’t mean that fuses are not directional. Capish? If you guys were really interested in the truth rather than arguing til you’re blue in the face you’d have done the experiment yourselves a long time ago. The other variables can be controlled. Like the placebo effect, whatever. Don’t you know that?

Note to self: Why do naysayers, the uber skeptics , the practitioners of uber careful pseudo logic always demand that believers must be the ones testing for fuse directionality? Why don’t naysayers test for themselves? Wouldn’t that be uh, more convincing for them? I mean, why would these uber skeptic’s even believe any test by a True Believer? It doesn’t make sense. Yet the demands for tests, especially the silly double blind ones. Give me a break! Tests are for sissies. My guess is the pseu-pseu-pseudo scientists don’t want to be found wrong and be the laughing stock of all the other self-appointed shepards of the pseudo audiophile flock. This whole anti fuse directionality movement is really a big nothing burger. 🍔
Geoff,

Don't waste your time or energy on these irrational people. It's typical of this generation to think they're right whether they tried things out for themselves or not. It's like my son-in-law who thinks everything he reads on the internet is gospel. I just sit back and watch him make a fool of himself. As the old saying goes 'experience is the best teacher'.
It is placebo effect IMHO, but there is nothing wrong with it - the result is what counts.  If it improves the sound, then why not?!  Trying to convince believers is wrong, as wrong would be to tell the truth to a person who gets headache relief from placebo pills.
A placebo effect wouldn't compel me to defeat the tone controls of my integrated to offset the now, too high treble boost. Nor would it extend the soundstage permanently, instead of occasionally, beyond my speakers. Nor would it alleviate the upper mid bass emphasis (which I thought was a permanent feature due to rear porting and close front wall placement). I could go on but the naysayers would write it off as a sort of delusion, which is pure and unadulterated crap. 

One of the main tenets of scientific study is that it is repeatable, by OTHERS. So, get off your butts and try it for yourself, and stop quoting the bits of "science" that gives you the warm and fuzzies but amounts to nothing more than another dose of "weak tea" reasoning.

All the best, really,

It is always good to remember that ’objectivity’ in all derivations of the word and it’s attached vectors and meanings..... exists solely at the will, whim, desires, aims, and projected stance - of an exclusively subjective reality. Objectivity is a projection. All forms of science attached to the leading edges, defining standards, fundamental concepts and historical backdrop of all human endeavor state this point unequivocally.

Except for the technical aspects of engineering and the nature of it's schooling and collective methodologies.

Such proponents, adherents, and mental leanings of a specific sort of mind of those who lean in that direction... they are taught that objective reality exists, or that it is implied within such a given collective envelope... that objective reality somehow -exists.

It does not.
