Geoff’s statement above is correct. See the first of my posts dated 10-28-2016 in the long running "Synergistic Red Fuse" thread, in which I quote posts that have been made here by Ralph and several other designers of well regarded audio electronics on the subject of fuse directionality. I quoted Ralph’s comment (which had originally appeared in another fuse-related thread) as follows:
Ralph Karsten of Atma-Sphere:
"… Fuses are inherently incapable of having directionality in any way whatsoever.
… I joined this thread recently with some results on testing. Those results are that the directionality appears out of coincidence and that actually greater improvement can be had by rotating the fuse in the holder for best contact…. Reversal is improving the contact area because fuse and holder are not dimensionally perfect and the fuse might sit better in the holder in one direction. By rotating the fuse in the holder without reversing it gets the same effect only more profoundly."
>>>>Whoa! What? If fuses are incapable of having directionality in any way whatsoever why do almost all users of aftermarket fuses in the past 15 years report better sound when the fuse is in the correct direction? talk about ignoring evidence. Do you guys really think there’s some sort of audiophile conspiracy? Do you actually believe that it’s group hypnosis? The placebo effect? Expectation bias?
Ralph’s hypothesis of the fuse holder accounting for the improvement when fuses are flipped doesn’t hold water since if were true that fuses are not directional and the fuse holder was the key, then flipping the fuse and rotating it would lead to worse sound in many cases, not better sound. That is IF the fuse holder contact area differences were even AUDIBLE which I actually don’t think they are. Talk about grasping for straws. You might as well use the time honored naysayer argument that it's the oxide on the surface of the fuse holder being removed whilst flipping the fuse that accounts for the change in sound.
"Rotating affects the sound more profoundly than reversing it? Huh? I thought you guys didn't think there was any effect from reversing the fuse. How could something be more profound? Give me a break. Besides, the whole fuse directionality issue is rather moot in light of the fact were already know ALL WIRE is directional. We’ve known it for At least 25 years. So of course fuses - ALL FUSES - are directional. Hel-loo! This is all just a case where some folks didn’t get the memo and refuse to believe there ever was a memo. Who knows why.
In view of the overwhelming evidence in favor of fuse directionality AND wire directionality in general - not the least of which is the comprehensive data contained on the HiFi Tuning website. perhaps it’s best to put the fuse holder hypothesis to bed. Don’t let the bedbugs bite.
