Unfortunately, the numbers you cite don’t - by themselves support - HiFi Tuning’s contention in their Interpretation of Measurements section that the differences are around 5%, or in the range of 5%, whatever. Those 4 relatively high numbers are OUTLIERS and can be thrown out. In fact, HIFI TUNING cautions AGAINST using glass fuses, IIRC. Most differences on the data sheets are, by far, an order of magnitude lower than 5%. End of argument. It should also be pointed out we ALREADY KNOW that directionality is only ONE VARIABLE involved with fuses sounding the way they do. Which is why folks often report aftermarket fuses sounding better than stock fuses right away, even when NOT installed in the right direction. Shall we review all the fuse variables?
Of course, the real interesting thing in the fuse measurements was that listening tests correlated to measurements, i.e., the best sounding directional was ALWAYS the direction with least resistance. It’s NOT random. Also note fuse holders were NOT used in the fuse measurements per se but their resistance measurements appears separately. So, we can dispense with the fuse holder argument.
This is all starting to look like a case of not seeing the forest for the trees.
If the glove doesn’t fit you must acquit.
