Fuses that matter.

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.

Hi Mapman - It seems like there's a growing consensus that IF fuses and/or fuse direction have audible effects, it must be as a result of fuse parameters that are either unmeasured or unmeasurable. If that's true, then the only "evidence" available for deciding whether fuses have audible effects is personal experience and anecdotal reports.

Recently I joined the ranks of those who believe they've heard differences among fuses (but, in my case, not fuse direction). By the end of this week, I will have fuses from each of the major manufacturers - Isoclean, Furutech, and Hifi Tuning. So I should have more to report by the weekend, FWIW.

Headed deeper and deeper down the rabbit hole. I hope I can find my way back.

Bryon,

You are a brave man!

Will look forward to your findings.

Remember that the primary function of a fuse is to provide protection against current surges. If a fuse sounds great but fails to blow when it should, that would be a no go for me.

Also I would be interested in value proposition as I am with all audio gear. IE is the cost justified? Is the cost of "audiophile fuses" justified compared to similar fuses sold for general use?

Also how can you determine if the same fuse will produce similar results in different designs, or at least reliably positive results in all cases?

THose are my questions. I don't expect you to answer them all for free, but might as well get them out there.
