Fuses that matter.

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.

My statement of Al's views in my previous post was based on the same information you have access to -- what Al has said in this thread. So I cannot speak for him beyond what I already have.

Speaking for myself, the answer to your question is no, I wasn't talking about "psychological reasons" when I used the phrase "non-quantitative" (not "non-qualitative," as you wrote). I was simply talking about ANECDOTAL evidence, which is typically non-quantitative.

But we've been through all this already. On 4/28, you wrote...

B C - not sure why you use the word intuition, that appears to be your way of saying this whole thing is psychological.

To which I replied...

As far as my own view, I made it clear that I DON'T believe that fancy fuses are nonsense, though I acknowledge that it is a possibility. So you could put me down as a Tentative Believer. That is a far cry from saying the whole thing is psychological.

My view has not changed since then.

Bryon

Geoff, I would put it that all of the technical rationale, technical data, and technical speculation that I have seen offered to explain the claimed benefits of expensive fuses, and Bryon has done a particularly noteworthy job of unearthing much of that, has been shot down on technical grounds by me, Roger, and others.

What remains is anecdotal evidence. What I have said regarding that is that I suspect that SOME (but not all) of that evidence is the result of either failure to recognize and control extraneous variables, or system dependent effects that in other systems may make either no difference or a negative difference, or misperception.

The reader can (and will) make his or her own decision as to how to proceed.
