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

Someone, Anyone, tell me what to measure with an VOM or LCR meter or any other way to know what direction to drop these fuses in.... I really don’t want to listen to them a week each way to figure it out... If it is that obvious, someone should have figured this out... So

There is no way, it’s all voodoo.

The minuscule amount, (millionths of ohms) that claim to have been measured can be attributed to all sorts of things as Almarg explained numerous times.
And let just say there was a millionths of ohms difference, do you think a regulator that sits next in line in the circuit would care one iota!!!!!!! this is all BS and so are the people that claim it to be so. what about the dirty plug wiper contacts in your power point.

What people are hearing is are fuses that have seen too many turn on cycles which sags and carbons/corrodes them up, just replace for the same $1 fuse and your good to go.
Here is the same fuse that has seen too many turn on surges, over time left to right.

Am I getting this right - those who don’t believe in fuse directionality do believe in cable directionality? No, I’m not talking about shielded cables or other special cases. Is it because fuses are so small? 😀

George, take it easy, dude. You might consider cutting back on the Joe.

Sidebar: How small can something be and still make a noticeable improvement? I gather most objections to the proposition that fuses can’t make a difference and that fuses can’t be directional have to do with the idea that fuses are just too small to make any significant difference. The fuse size is too small, the wire is too small. Which leads to my question. How many things can you think of that are very small and yet improve the sound? We can start off with tiny little bowls the diameter of which are around 7/8" or 1" and the PWB Silver Holographic Foil that is a mere 1/8" by 0.75" and Marigo VTS dots that are as small as 1/16" diameter.
Can a fuse sound better than no fuse, as if it was bypassed, and if so, how? Does it somehow filter or organise the electron into a certain orientation?

No.

A fuse has a voltage drop and in the case of fast blow fuses, one that can be pretty variable as current varies through the device. This usually has an adverse effect on the sound if nothing is done in the circuit to deal with the phenomena.

Eliminating it is usually not an option as the equipment can become a shock and fire hazard and may do things like blow up amps and speakers if something goes wrong.
