Directionality in fuses???

[Vovk Z]

for ac current the solution is obviously just like using back to back electrolytic capacitors. Just put two fuses in series, with opposite directions.

This also should help reduce any coloration caused by fuse directionality. Of course one must carefully match the fuses' strengths of directionality for cancellation to be optimal.

It can also be derived from the practice of putting smaller, high quality capacitors in parallel with larger capacitors, that one should put high quality lower current fuses in parallel with higher current ones.

I must quote it. New great knowledge about fuses.

A large fuse has large parasitic parameters so we have to divide it by using parallel smaller ones.
And, of cause, if we can't use two fuses in series with opposite directions then we have to direct our one fuse from amp output right to the listener.

Nothing to make a "fuse" about.

 

[Vovk Z]

Therefore, it is clear that, even if the resistance (impedance with AC) is not the same in both directions, the errors will cancel out, resulting in a smoothed average waveform on the downstream side of the fuse."

No, I can't agree. If the impedance is different in both directions (as in diode) - that means it is non-linear element, so there is non-linearity, and it can't cancel out.
"It is clear" that " a smoothed average waveform " means a smoother sound. We don't need that. And mirlo has presented yet a great decision for this.

On a side note, AC current or AC signal is not really symmetric. There's element of it that is directional.

If fuses make an audible difference in your hardware, throw the hardware out.

I would then imagine the copper traces to and from the holder are also directional?

 

[mchambin]

BS is directional as well.
Fun to throw, no so to get.

..and on that note it's time to go. Nothing new is being added and this thread has run its course.
