That’s preposterous. Why on Earth would you believe cables can be directional but not fuses?Because as I’ve said numerous times in numerous fuse-related threads in which you’ve participated:
If Geoff’s comments about all wires being significantly directional are to be believed, then these differences [referring to the almost infinitesimal direction-related differences in fuse resistance that are reported in the HiFi Tuning paper which you continue to cite] would be totally swamped by BOTH the resistances and the alleged direction-related resistance differences of the vastly longer associated wiring. In the case of mains fuses, that would include the power transformer and the power wiring in the component, as well as the power cord and the AC wiring in and outside of the house.Those having an understanding of how resistances or other electrical quantities that are in series combine, as well as an understanding of the fact that most cable parameters and cable effects are proportional to length, will understand that. Or, more precisely, **almost** all of them will. There are always a few outliers, as you would say.
You may disagree, and for that matter I’d expect that you will find some way to disagree. But I wouldn’t be so quick to characterize my contention as "preposterous."
