Fuses that matter.

On Page 4 of the Hi Fi Tuning data sheets, the following comment is made.

"The measurements done so far showed some measurable differences between fuse(s), but didn ́t explain completely the sonic differences between fuses."

Thus, there's no reason (for a skeptic) to hang his hat on either the resistance data or the noise data. It is actually a strawman argument, a logical fallacy, to protest that very low differences in noise and resistance proves, or is evidence that, differences in fuses and fuse directionality are not audible.

Hi Bryon,

A diode will conduct current when the voltage at the terminal FROM which the arrow is pointing is greater (i.e., more positive, or less negative relative to some reference point) than the voltage at the terminal TO which the arrow is pointing. (And with most diodes that difference in voltage has to be at least several tenths of a volt before significant current will flow).

What makes it confusing, though, is that when conduction occurs the direction of electron flow is opposite to the direction of the arrow. That is because by convention the direction of current flow is defined as if positive charges were conducting the current (from + to -), even though electricity in metallic conductors is conducted by electrons which are negatively charged (flowing from - to +).

I have no idea, though, what HiFi-Tuning intends the arrow to signify, if anything.

Best,

All that I am convinced of with the HiFi Tuning fuses is that the logo is always in the same direction. Of course, we really don't know which direction the arrow should go. If the hot lead goes into the circuit and the neutral comes out, presumably the arrow should go from the hot IEC lead into the component.

Mapman, yes data hopefully suggests that the null hypothesis is rejectable and thus that something is going on between the variables. The hypothesis is tentatively supported.

I don't think we are near to stating a hypothesis much less testing it properly. Rather we are not even engaged in assessing a hypothesis, we are dealing in an anecdotal world, such as wine tastes, etc. All that am saying is that it is ridiculous to a priori reject that any variable can be found that contributes to the sound of a fuse.

"All that am saying is that it is ridiculous to a priori reject that any variable can be found that contributes to the sound of a fuse."

I would agree if reworded slightly.

"All that am saying is that it is ridiculous to a priori reject that any variable that might be found contributes to the sound of a fuse."

That would include the user thinking he heard a difference, not just factors with the electronic equipment. That can clearly be a factor.

Bryon, you and Al think there are NON-QUALITATIVE reasons to believe fuses/direction can have audible effects? That's very interesting. Do you mean psychological reasons? Please expand.
