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 have a SMSL Bluetooth amp on my back porch that I use with in ceiling speakers.  When I sold my Thiel speakers last winter, I set them up in my shop with that SMSL amp.  Thiels have the reputation of being hard to drive so I was kinda wondering if that little amp might burst into flames when I turned it on.  It was fine although I started with the volume turned down really low.

So I’m playing songs through my iPhone with Bluetooth to my Thiel speakers and I was amazed at how good they sounded at first.  Really shocked.  I turned up the volume a little and then I could tell that the sound was lacking.  But without the experience of hearing a good hifi rig, I can see how someone would be satisfied with the sound of these amps and not feel the need to spend more money- at least until they bring home a $2000 amp to try.

You get the 20-20k range with any amp but more money brings better bass, smoother highs, timber, 3d holographic sound, imaging, space, blacker background, etc.

The coolest experience with my rig these days is to play a Chorale piece.  The singers go wall to wall and up to the ceiling.  I can make out each individual voice in the choir vs. being just a cloud of sound.  It’s not for everyone but that gives me a thrill.

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.
