Fuses that matter.

Roger makes a compelling case. When I hear things like that, it erodes my confidence in my (already tentative) belief that fuses have audible effects. Having said that, I conducted a second experiment (I use that term loosely) that corroborated (I use that term loosely as well) my initial impression that fuses do in fact have audible effects.

In my first experiment about a week ago, I A/B'd the stock fuse in my amp with a Hifi Tuning fuse. I swapped back and forth about 15 or 20 times. Each time, I heard a difference (or to put it less controversially, I BELIEVE I heard a difference). What surprised me almost as much was the fact that I preferred the sound of the amp with the stock fuse (15¢) rather than the fancy fuse ($50).

The day before yesterday I conducted a similar experiment with my preamp. Again, I swapped fuses maybe 15 or 20 times. Again, I heard (or believe I heard) a difference. Again, I preferred the sound of the stock fuse.

In both the amp and the preamp, the Hifi Tuning fuses had a strange phasiness, lack of pitch definition in the bass, and imprecise imaging. None of that was audible with the stock fuses.

Possible interpretations of the data...

1. Fuses have audible effects.
2. I am crazy.
3. A butterfly is trapped somewhere in the house.
4. All of the above.

Which of these is true remains unclear. So I've done the only thing a sane, rational, and sensible person could do.

I've ordered a Furutech fuse.

Bryon, Roger talks about any detectable change in sound while we discuss here if "major difference in my sound" that Tbg experienced can be repeated and benefit others.

The assumption that differences in resistance are (solely) responsible for fuse directionality is most likely a false assumption, a strawman argument as it were. As would the assumption that differences in capacitance, if any are measurable, are (solely) responsible for differences in sound. These are precisely the same strawman arguments that skeptics of cable differences have put forth for more than thirty years - I.e., cables that measure the same must sound the same. Of course, any yutz with ears knows that's not the case.

"These are precisely the same strawman arguments that skeptics of cable differences have put forth for more than thirty years - I.e., cables that measure the same must sound the same. Of course, any yutz with ears knows that's not the case. "

One could argue that with a the right set of complete and relevent measurements, cables with similar characteristics,including things like solid/braided construction, shielded/nonshielded, etc., in addition to the usual common electrical/ratio data type measurements, will tend to sound similar.

Mapman, that's true but if you take into consideration things like purity of metal, resistance, inductance, capacitance, dielectric constant and absorption it will be all multiplied by hundreds in power cable simply because of the length not to mention things that don't even apply like shielding. I'm only skeptical about "major difference in sound" in my system.
