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

With regard to fuse direction I believe the 50% ... 50% ... 98% rule applies ... simply stated when ever an audiophile has a 50 / 50 chance of installing a fuse in the correct orientation ... 98% of the time he will select the wrong direction .. how else can you explain that anytime an audiophile installs a fuse and then reverses it ... there is always an improvement

I also think the test is flawed ... has anyone ever reversed the fuse an heard an improvement only to back test it by reversing the fuse again to see if the improvement is lost .. you know a simple ABA test ... never seen anyone post about that

@charles1dad , 
"out of phase"was a spot on analogy about fuse direction. Lots of things can sound right when out of phase and yet something is amiss with other parameters. They are different, for sure, and I must stress that for me, the differences are of an amount significant enough to point to the better of the two choices.

There is some theory that I can't remember concerning distortion and other anomalies in hearing thresholds that was a cornerstone of sorts until some people were tested and found to have hearing acuity 10x greater than the limits originally thought. That was some 5-10 years ago.

Our ears are some fairly sophisticated devices that are, at present, unmeasurable with current testing devices when it comes to detecting false signals, cues and the like. Science has to take a long and serious look to see those differences with technology unavailable to the general population.

All the best,

The placement of the fuses regarding direction  is random.  In my DAC and Line Stage the initial placement was better than when I subsequently reversed them. With my mono block amplifiers reversing the initial placement led to an improved sound.  The point is that it's truly random choice and both directions need to be heard.

When I read "out of phase" I think back to the old Shure test LPs. I have a hard time reconciling that a fuse in one direction sounds good and in a different orientation sounds out of phase in the manner presented by the Shure LP.
