HiFI Fuses ?

I'm with Bob P. on this one. I've yet to read a reasonable explanation for a fuses directional aspect, within any part of an audio cicuit. I'm open to explanations, though.

inpep---, so the neutral does no duty relative to serving as a ground often for the circuit and the chassis? Also stop switching the discussion to speaker-wires. They have nothing to do with this thread.

All that I can say to both you and Metro is that you should listen first and consider afterwards whether your understanding of circuit design can cope with what you hear. I know you hold desperately to the predilection that fuse direction cannot matter and want no evidence that you are wrong.

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.
Salut, Bob P.

Inpep___, I have no need to provide you with evidence any more than you have to provide it that ac within components is the same as in speaker wires and phono wires. If you have personal experience that you can hear no difference in fuse direction that should be satisfactory for you, but don't pretend that those who hear a difference cannot be given your expertise in understanding electronics.

I have no idea how a direction is established with the IsoCleans or holds on other fuses. I did ask the IsoClean people at CES, but they just smiled. I do know, however, that when I put them in counter to the correct direction with the hot wire toward the transformers, they do not sound as good as the other way around.

Tbg - Might you steer Bob and myself to some technical articles able to explain how these directional fuses work over conventional variations? I can't speak for Bob, but with over three decades of electronics background, I'm unable to grasp how a "directional" fuse could perform better in one dirrection over another, in any AC circuit, of which Bob has already mentioned some audio-related examples. Does ANYBODY have technical info able to explain?

People provide endless personal testimonials for a vast assortment of products (some "questionable"), but to a large percentage of audiophiles, this isn't "proof" of positive performance. I'm sure there are numerous products that even YOU scoff at without trying (clocks, pebbles, etc).

Surely we can keep this civil.
