HiFI Fuses ?

Benie, I always thought that looking for explanations on how or why things work was called curiousity or having an open mind. Simply stating that one doesn't care about 'why one hears a difference' or stating that why or how something works isn't important, shows a bit of closed-mindedness to me. But then, marketers just love those supposedly open-minded people.

Ah yes the directionality feature, which might make sense IF the current always flowed in the same direction. Unfortunately AC current changes direction 60 times a second and makes the direction that a so-called 'direction oriented' fuse a moot point.
Its the same principle for speaker cables, the current is AC and therefore direction of cables (except for the grounding or shielding point) does not exist.

Which misinformation? So AC current does not change direction? Ground and neutral are not necessarily the same. Even if the 'directional' fuse were a partial diode, it would act as such in either direction installed since the current reverses as many times as the frequency indicates. Grounding doesn't come into play here.
The last time that I looked at the amplifier output connections to the speaker I saw the voltage swing from positive to negative, therefore the current varying as such. When directionality is shown on cables it is to indicate where the connection for the shield should be, usually at the preamp, not the direction of the current or signal.

TBG, I need more than apocrophal evidence that direction matters, since I don't even detect any difference in even 'ordinary' fuses let alone 'directional' ones.
By the way, what is directional about these fuses, besides the arrow (I presume) marked on them?
As for speaker wires not having anything to do with this, - well, I use them as an illustration of why directionality has no effect on circuits or wiring when they deal with AC currents, grounded or not. Perhaps you object to my use of that example because you have no evidence that I am incorrect about that.
Remember that a fuse is just a short piece of wire with the added property of melting at a given temperature, the heat being caused by the current through the wire, changing direction continuously.
