What is the science behind audiophile fuses?

@tonywinga Picked up an Amazon 3/8” (5mm) x 12” 99.9 pure copper rod a few days ago. Cut to 20 mm lengths, cleaned them up and took the plunge. Wow is all I have say…every aspect of the music Is improved over my audio fuses. Risk yes but low in my mind.  I have never had a component fuse blow. All components plugged into protected power conditioners.  I Make sure they are only powered up when I am using and I unplug them during any rare power outages as a backup.  Waiting for a higher grade conductivity copper slug to compare with these once it arrives.  🤞🤞 SD fuse box does seem like a nice insurance for more expensive or rare components which doesn’t really apply to me. 🤔

@thyname thanks for the shout out as the original "we don't need no stinking fuses" guy.

I have tested the Swiss Digital Fuse Box and recommend it over any fuse.

My impression was that it wasn't as good as the "large gauge piece of metal" (high conductivity copper) but not a lot of difference.  If you feel you need/want electrical protection, I recommend the SDFB.

I think some people are confused about the configuration of the SDFB.  It provides better protection than a fuse.  Generally a magnetic current monitoring circuit will trip much faster than a slow blo fuse.

Of course we've all had experience where a compoent failed and the fuse didn't protect it.  that's just the nature of electronics  the fuse protects against upstream disturbances more than downstream failures.

No way!  I’m ordering the copper slug.  Wait.  What if the copper slug does more for the sound than upgraded fuses?  Then I’ll be torn between protecting my amps vs better sound.  Or worse, I have to spend more money and get the SDFB’s.  The saying is so true:  “Ignorance is bliss.”

A corollary to Murphy’s Law:  A $10 transistor will blow to protect a $0.10 fuse.

Is everyone familiar with Murphy’s Law? It states that if something can go wrong it will.
Corollary 1: When left to themselves, things go from bad to worse.

My favorite: in order for something to become clean, something else must become dirty, but everything can become dirty without anything becoming clean.

HI, I see the issue of fuses like so many other things in the world of audio and that revolves around why it is worth buying a power cable, or any audio component from certain famous and expensive brands. A class D power amp can be had for less than $1000 and can play music from 20hz to 20khz. However, there are people who buy $100,000 power amps that also play 20hz to 20khz music. Those who can afford it will say that this purchase is because subjectively the music sounds better with that amplifier than with another one at a much lower cost. Spending $600 on a penny-priced fuse is one of those situations. I am not satisfied with the statements that a HIFI fuse has no effect on the sound of a device, based on the fact that the manufacturer would put it as standard if that improvement in sound was true. 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. I don't know many people who keep their black power cords in their high-end appliances.
