Determining current flow to install "audiophile" fuses.

"Well I guess if one is a theoretical physicist one can propose pretty much anything they want. After all it’s all, you know, theoretical. Some might even buy into the theory. Funny how these things work.

Also so I feel slighted a bit in that I don’t expect others won’t hear something just because I didn’t yet some expect most all will because they and others think they do. All that despite the fact that even the most knowledgeable EEs on this sight have clearly expressed their views which normally get a lot of traction..."

Actually the whole directionality thing is probably more of a physics issue than a EE issue, which is probably why we cannot seem to get any explanations from EEs. I have been involved with the atomic physics of crystals for eons. One need look no further than my Brillaint Pebbles, the first comprehensive application of mineral crystals to high end audio and I won’t get into the paper I presented in school at the national AIAA conference on the design of a low thrust rocket engine for interplanetary travel that employed metal crystals bombarded by high energy Xenon ions to develop a net thrust from atoms sputtered from the metal surface. Ergo, for the metal conductor of cables, you know, what with the crystal lattice strictest that get deformed when the wire is drawn through the final die, and of fuses, the directionality they exhibit is acually a physics issue more than a EE one.

George’s latest input duly noted. I appreciate all the angst nevertheless, guys.

I installed 4 synergistic research red fuses in my Odyssey Khartago
extreme and the results were awesome. Each fuse cost about $90.00. This
has been the most cost effective modification I have ever made without having to use my soldering iron. It is my intention to call Klaus and tell him to offer these fuses as on option on new units. He should also put them in demo units at shows so that everyone can hear the true potential of his amps. Synergistic research has recently started selling black fuses (with
even better sound) for $120 each and I will be be upgrading to these black fuses soon.  Have a look at "synergistic red fuse" in the Amp and Preamp forum. I have no connection with Synergistic research and the only reason I am making this post is that I am a fan of Odyssey power amps.
Good luck

Wow!  Well hot dog those must be some truly brilliant pebbles even if you must say so yourself! 💥

Fuse directionality is not something exclusive to only high-end fuses. I found that even cheaper fuses have a preferred direction. One way to find out is to look at the cap ends with a magnifying glass. I found that the majority will have the power rating stamped on one end, and the other will usually have an assortment of symbols. Yes, I found the OEM fuses even sound better in one direction, but not the same as the high-end ones. I have the Hi-Fi Supreme fuses.   Before plunging, I tried ceramic fuses of the same rating as the OEM. They sounded a bit smoother than the OEM. I simply diagrammed on a paper the direction using the cap's indicators. So far, its been consistent for each fuse. They key is, one direction will sound smoother in comparison.

What you are most likely hearing is the warm-up of the unit after its been powered down in order to replace the fuse. I think you will find that this is repeatable, regardless of which direction the fuse is installed. This is an excellent example of expectation bias.

No, actually it can’t be expectation bias or warming up of the component, inadvertently scraping off the dirt or oxide from the fuse holder or even placebo effect. We’ve already been over that. You can easily eliminate those possibilities through careful testing.  It’s due to the non-symmetrical orientation of the crystals in the conductor. I can provide a paragraph describing the Backfire Effect if anyone is interested. No strings attached. Ironically the reverse expectation bias might actually explain why some people can’t hear directionality.
