What is the science behind audiophile fuses?


There were many threads on the topic of "audiophile fuses" on this forum, and I sure don't want to open old wounds and trench warfare. The fuse on my preamp blew suddenly two days ago, which prompted me to search for a replacement. That's when I came across the term "audiophile fuse" and the fact that they demand far-out prices. Deeper curiosity brought me to several other fora, where users posted glowing praises about their Zero fuses and other exotica. Now I am a scientist, but not a physicist or electrical engineer: so please enlighten me! How can a fuse have an audible influence on the signal, when the signal does not even pass through it? How can a fuse be "directional" when it deals with alternate current? I mean, if I recall my university physics, a fuse is basically a safety valve and nothing more. Am I completely missing an important point here? My scientific field is drug discovery, and because of this background I am thoroughly familiar with the power and reality of the placebo effect. I that's what I am seeing here, or is it real physics? I need objective facts and not opinions, please. I really appreciate your help!

I am looking forward in reading about your impressions /thoughts on the HiFi Tuning Fuse.  I have one (Silver) in my Marantz CD/SACD player that was switched out by the prior owner.

 

Happy Listening!

If we apply that same rule, why do 90% of the owners of amplifiers such as Boulder, Pass, Soulution, etc. buy a power cable, when the device already comes with one as standard.

Probably because they can.

Perhaps those that buy those amps are more susceptible to suggestions surrounding why they made that purchase in the first place?

Everyone jumping on the bandwagon is rarely a good argument.

Either way, does not answer the ops question. 

Just about 10 days have passed since this thread started.

Nothing has been established-just as expected.

Littlefuse=couple of bucks for a handful

Audiophool fuse= MANY dollars for 1

SQ end result-whatever your brain convinces the ears.

“Nothing has been established-just as expected.”

Sure, from your dogmatic, inexperienced in things hifi point of view nothing is established.  The prose, these words written here have given you no great revelation.  You came in with the “Audiophool” attitude so why would you expect anything different?

Just as I wrote earlier, these types of discussions were much less common when audio stores were more prevalent.  People could hear for themselves the sound of different brands and levels of components.  Now days, we have so many, “armchair audiophiles” with little to no experience in things hifi, who have not heard some great hifi systems in person and therefore believe or want to believe that anything more than they are willing to spend on Amazon for gear is a waste of money. 

Don’t even get me started on people who review systems they hear on YouTube.  Just like TV commercials in the 1970s showing us how their TV has a better picture than the TV we are watching the commercial on.

Whatever your brain convinces the ears ! ?

I've experienced listening to a fuse shootout on a guitar amp using a glass fuse , a Littlefuse ( or Bussmann ) , a cryro'd ceramic and a gold plated ceramic .  Yes I heard differences ( small but discernable ) the end result the My brain convinced My ears that  the Littlefuse sounded best , does that make the other fuses inferior ? No I liked the sound of the plain ceramic fuse .

Now  , my amp has 7 fuses 1 main and 6 on the board so I went to our local electronics supply and was able to purchase the 3 different values of  generic ceramic fuses replacing the glass ones .  A few months later no sound out of one channel so lifting the 56 lb. amp on to the bench and testing the fuses I found one of the four 6 am fuses blown . This pissed me off ( my own fault for using generic fuses , so I ordered Bussmann fuses and Wow just changing from the generic fuses made a sonic difference/ improvement .  $2.00 each verse 50 cents , OK so how o\would a HiFi Tuning , a Synergistic Research or some other Audiophile fuse sound ?  I considered the HiFi Tuning because they were the least expensive but   when a Furutech showed up at 1/2 price $35.00 I had to try it on the mains input only .  Does it sound better ?  Well My brain convinced my ears that is does  BUT when doing a back and forth with the Bussmann and the Furtech my wallet said yes the Furutech sounded a little bit better but not nearly enough to even consider replacing the other 6 fuses on the amp .  I have replaced all glass fuses in my system with Bussmann or Littlefuse ceramic ones . But if I win the Lottery then maybe ?
