Will there be any 'Arrow' mark in a Fuse holder?


Hi Everybody, I am new to this Forum. Please clarify that,

Will there be any 'Arrow' mark in a fuse holder to show

the direction to fix a fuse? Will all type of fuses have

'Arrow' mark? I need the advices to upgrade the fuses.

In one of a forum, I read the following 'Message'as follows:-

"The fuse has to be parallel to the overall direction of the sine waves coming from the wall socket and into you audio gear. If they enter at an unusually steep angle, the top (or bottom) peaks and throughs will get clipped off or attenuated and you will get jagged or almost square waves in you signal. The resulting SQ will be harsh and grating to the ears. Prolonged usage may damage the speaker coils as well."

So, friends,please give me a clear picture to replace a

'fuse' in my Preamp and DAC. Thank you.

Regards,

Rhapsodi.

Is there really anyone here that believes the direction of the fuse is going make their system more musically satisfying?

It would seem so, yes.

I don't know how some stick with the limited understanding of EE so close-mindly.

It's fine to be open-minded, but not so open-minded your brains end up sloshing out onto the floor. And that's the sort of open-mindedness fuse directionality demands.

TGB, this presumes the resistors were line up properly prior to the paint application?

Or that the cores were lined up properly before the end caps were attached. :)

No, Simply_q, yours is the close-mindedness I am talking about. Just try it, if you hear nothing, I will apologize and add this to my list of things like music absolute phase that some just don't hear.

What has my trying it have to do with anything? My trying it would bring absolutely nothing new to the table.

By the way, it's absolute polarity, not absolute phase.

The point of trying? If you haven't heard it, or tried it, YOU HAVE NO OPINION.

Nonsense.

When someone makes claims with the implication that there is actually something physical behind it, I don't need to have "heard it" or "tried it" to have a valid opinion on the matter, nor would my having "heard it" or "tried it" bring anything new to the table.

It's amazing how so many, that know so little, find so much to type about.

So where are those who know so much more? Who might be able to actually expand our knowledge on the issue? They seem to be conspicuously absent.

How about you?

Obviously you would have to know so much more in order to rightfully claim that I know so little.

What enlightenment and expansion of our knowledge do you have to offer on the subject?

OH- and FYI, "absolute phase" is also a correct term: (www.omegamikro)

No, it's not.

Phase is a relative term, relating to one or more waveforms with respect to time. The issue at hand has nothing to do with time. It's about compression versus rarefaction, or positive versus negative. It is decidedly an issue of polarity, not of phase.

The proper term is "absolute polarity," not "absolute phase." It was first coined by Clark Johnsen in his 1988 book, The Wood Effect. It has since been perverted into "absolute phase" by those who don't know what they're talking about.

Simply_q, it is irrational to refuse scientific observation...

Scientific observation? Exactly what scientific observation is that?

You are right that it really is absolute polarity, but many call it phase.

Then they should call it what it really is.

Tbg

Simply_q, simply put, you don't know what you are talking about.

Then instead of saying "you don't know what you're talking about" set me straight. Offer up something to expand one's knowledge on the underlying phenomenon.

You say, "there is actually something physical behind it." This is just nonsense. How would you know there is nothing "physical" behind it?

Why don't you quote the entirety of what I said? Which was:

"When someone makes claims with the implication that there is actually something physical behind it, I don't need to have "heard it" or "tried it" to have a valid opinion on the matter..."

The only opinion I expressed on the matter was that for one to accept prima facie that fuses are directional is to have one's mind so open as to allow their brains to slosh out on the floor.

I feel that's a quite sound and rational opinion.

How would you know there is nothing "physical" behind it?

That's not what I said.

Essentially what I said was that there's no obvious reason for that to be the case and so far no one has offered up even a plausible theory for it to be the case and to believe that it is the case is to go beyond being open-minded.

Try a little education(though I doubt you're interested), and read the fourth section of this article(relating to harmonics): (www.arbiter) (en.wikipedia) (www.gcaudio) (www.sweetwater) OH, THAT'S RIGHT: None of those people know what they're talking about(ROTF/LMAO).

The first article is irrelevant as it has nothing to do with absolute polarity in the context being discussed here, i.e. acoustic polarity. The part on harmonics is just as irrelevant.

The Wikipedia article isn't referring to absolute polarity, nor is the Sweetwater article.

Absolute polarity refers to the acoustic polarity of the acoustic waves produced at the original acoustical event. There is no "phase" to this. It is compression vs. rarefaction. Which is polarity, not phase. Again, phase is relative. There's nothing relative about the original acoustical event. It is the reference itself.

Simply, let me see what does observation mean? Watching, listening, measuring, ie. using ones senses. What does scientific mean? Being as objective, seeking scientifically transmissible data, measuring with valid instrumentation, ie. being as open to what one is focusing on as possible.

Great.

So now where does the "scientific" part factor in here with regard to directional fuses and your claim of "scientific observation"?

If all you're doing is listening, then by definition you're not being objective. Listening on its own is a decidedly subjective matter.

I repeat my earlier statement. You are close-minded and apparently fearful that you will hear something, although the nocebo complex, hearing nothing because you believe you won't may affect you.

Not at all.

You're not getting it.

Even if I tried it and did perceive a difference (please note I did not say "hear"), it would prove nothing one way or the other.

Why?

Because I'm a human being. And like all other human beings, I'm just as susceptible to perceiving differences even when none exist in any actual physical sense.

And until that ambiguity can be adequately controlled for (and it can't be controlled for by way of vanity and ego), my trying it for myself is pointless.
