Fuses that matter.

Hifitimme, all of what you say maybe true, but it may be that it is "significant." Why do fuses sound different? That is the real question with which you should focus. As they sound different, what is wrong with people buying what they prefer? Would you argue that all wines differ insignificantly and that people should buy the lowest price ones?

There is nothing wrong with people buying what they want but surely nobody can object to getting the facts straight as well?

Hifitime, you make some excellent points regarding the measured resistance of the fuses. The same arguments can apply to be made to the measured noise as presented in the HI FI Tuning data. But I think this was really the point of the data - to show that the electrical characteristics, at least the two obvious ones they measured, of a fuse are not symmetrical (i.e., they are directional) and that the (very small) measured differences are NOT stufficient to account for the difference in sound, as Hi Fi Tuning is careful to point out. Essentially, you are agreeing with Hi Fi Tuning.

Next up for consideration, Things that are Too Small to have any impact on the sound. That should be fun!

Twilight Zone!

Where's Rod Serling to explain these things when you need him?

Seems to me the two possibilities (not mutually exclusive) are the differences in fuses do make a noticeable difference in sound or the listeners think they heard a difference that they attributed to the fuse but in fact they were mistaken.

So based on the measured data provided, I'm still leaning towards that the electrical effect of the fuse is in general too insignificant to matter.

Maybe someone else will come up with some new measured data to contradict? I will not discount hearsay as data categorically but it will take a lot of that from a lot of people that I trust to sway my opinion.
