Synergistic Red Fuse ...

I’m wondering if any of those who have experimented with fuse directionality have tried simply removing a fuse and then reinserting it in the same direction, but such that it is rotated through a significant angle (such as perhaps 180 degrees or so) about the axis corresponding to its length. Or perhaps simply removing it and then reinserting it without any apparent rotation.

The point to that experiment being to determine if the differences that are perceived may simply be due to minute differences in the physical contact between the fuse and the contacts on the holder. While that may seem to be an unlikely explanation for differences that may be perceived and attributed (or misattributed) to directionality, from a technical standpoint it strikes me as nevertheless being a less unlikely explanation than the essentially infinitesimal differences in various parameters that have been reported to have been measured between the two directions in a couple of papers that have been published, for example, by HiFi Tuning.

Of course, even that kind of experiment would not rule out the possibility that other effects might be in play, such as sonic differences that are sometimes reported to result from simply turning a component off and then on a few minutes later.

I’m not sure we don’t already have an answer to the whole wire and fuse directionality issue. In fact we hd the nswersgoes about 25 or 30 years ago when cable mnufacturers first began putting arrows on their interconnects and other cables. And how do they know which way the arrows go? They know because they have done the experiments and found that one direction - as the wire comes off the final die - or as the wire comes off the big spool - sounds better than the other. It’s not really all that subtle. Anyway, once you find out the orientation of the wire as it comes off the spool that sounds best as a manufacturer you simply keep track of the manufacturing process of all future wire, even the wire for fuses. If you are not manufacturing the fuse yourself as the manufacturer but modifying a stock fuse you simply don’t put arrows on the fuse and let the customer do the listening test. For interconnects and other cables or even hook up wire it’s ridiculously simple to keep everything straight. It’s also rather easy to eliminate the contact issue from the equation. Not that the conract surface isn’t an issue. Any old fuse is directional, even stock fuses respond well to flipping them.

Fascinating Fuse thread.

The problem I have is I can change nothing and things may still sound subtly different to me day by day, listening session by listening session for reasons unknown.

But the differences are subtle and seldom ever affect my end enjoyment. I suspect my own mood and perhaps mindset of the hour to be a factor especially when it comes to any emotional response to what I hear.  "Dammit Spock,  I’m a person not a listening machine." Probably a good thing.

I do not have time to dabble with fuse directions normally. If there was a problem to start with and I thought it might be that, I probably would. but I can’t even account for how things that vary regularly out of my control like weather, air pressure, humidity electricity etc. are affecting what I hear exactly at any particular time versus another.

Or how can I even assume my gear always works consistently and that there is not some natural audible variation over time? There is a lot of complex technology in these toys.

So I just throw in the towel and be happy I like it as much as I do regularly. Not the "audiophile" way of thinking I’m sure.

I guess if you flip or change fuses enough with enough a/b tests the results become obvious.

On the Subject of Fuse Direction.

The synergistic Research Fuses are Quantum tunneled in one direction-
from the "S" of the word Synergistic  towards the "h" in the word Research. So at least this corresponds to the arrow of some other fuses. You want Current to flow from the capital "S" towards the other end of the fuse where the last letter "h" is.  
So on some fuse holders ( like the tray type holder next to power cord connectors) , it is easy to figure out the "hot" side and the "neutral" side and put the fuse in in the optimum position on the first try. The other spots one has to experiment for optimum results.

I hope this helps.
