What direction should Hi Fi tune fuse be installed

So so I'm still waiting for someone to expand the scientific and engineering knowledge base and offer up any advise or theory to help answer the original OPs question.

If the answer is that there is no answer other than trial and error, I'm fine with that. Maybe the mysteries of HiFI tuning fuses will be answered by science someday.

Or even better, if the vendor could provide the answer, that would make it pretty easy for anyone concerned to validate it or not.

Alternatively, there is a lot to be said for the old motto "if it ain't broke, don't fix it". There is always something out there worthy of one's attention at any given time. Fuse direction probably ranks pretty low on teh grand scale of things I would wager, even when one is easily affected by "audiophilia".

And what if the expanded scientific and engineering knowledge base maintains that there is no directional difference? At what point, if at all, would you (we) accept that any perceived differences are imaginary?

Hardline subjectivists seem to maintain that if there is no scientific explanation for perceived phenomena, it just hasn't been found yet. It's intellectually sloppy to not balance that perspective with the possibility that the perceived phenomenon may be bogus, don't you think?

Mapman, if I can be so bold can I suggest you do your due diligence? While we've undoubtedly covered this before somewhere ( I can see you wracking your brain) I suspect you might get some of the answers you seek by going to the HiFi Tuning web site and taking a gander at the technical data sheets that show, among other things, differences in resistance according to direction of fuse, differences in resistance according to fuse conductor and end cap metal type, differences in resistance according to cryo and non-cryo treatment. Things of that nature.

When someone says a thing is almost impossible what that actually means is that it is possible. - Old audiophile saying

Item number 2 in my Get Rich Quick scheme: A unidirectional fuse! That's right...along with my previously mentioned "Deconfuser" testing apparatus, I plan to market a fuse to the confused that can be used in either direction with less chance for fuse abusing. I'll put little arrows on 'em going in BOTH directions declaring once and for all that bi-directional fuse useage can unconfuse users, leading to peace and harmony for all.

Drubin, balance, as usual, is where the truth lies. What you say is true, but
it would also be intellectually sloppy to not balance one's perspective with
the probability that the scientific explanation has, indeed, not been found
yet. When one considers how much we are still learning about our
universe, that perspective is not unrealistic at all.

Now, why exactly, is it so important for the skeptics to want to "set the
record straight"? Why does it matter so much that some are
convinced that the perceived reasons are real? Many seem to take on the
role of "protectors of the naive". Please! Here's what I do know;
and without a doubt:

- None of this is essential for the enjoyment of music. That fact is the great
"balancer". It's great fun (for some) and can certainly add to the
enjoyment. It can also take away, if one is not careful; but, the true music
lover doesn't have to worry about that. If one can let obsession over tweaks
distract from enjoyment of the music, then I would question just how
important the music is to the listener.

- I don't have experience with "high-end" fuses, but being both a
musician and audiophile I can say that the parallels between the tweaking
that musicians and audiophiles do are many. The differences in sound that
many musicians concern themselves which are a result of tweaks to their
instrument are usually much more subtle than those that audiophiles
experience via tweaks; and, these differences are very real. Sound, being
both the exciter and the victim of resonances is affected by just about ANY
change that one makes to that which is creating the sound. How this
happens in the electrical domain I will leave to the more technically astute,
but it does not seem much of a stretch to me to assume that the
phenomenon is real. You think that it's weird that fuse direction might affect
perceived sound? What if I pointed out (as but one example) that some
very fine and successful saxophone players feel that wether the little screw
that secures the saxophone's neck in place is gold plated or is silver plated
makes an appreciable difference in the response and sound of the
instrument? To the player, anyway.

- The problem is when a musician who needs much more attention paid to
his intonation or other rudiment obsesses over the tiny changes to his
sound by having the little screw gold plated. I think the parallel to
audiophiles is obvious.

- Not everyone has the same hearing acuity or interest in hearing small
differences in sound like the ones being discussed.
