Audio Magic Ultimate Premier Beeswax SHD Fuse

OMFG! You just had to know Paul would weigh in on this one!

I've listened to many after market fuses. They will change the sound because they are not constructed like a fuse. I've taken a few apart.
There are some pretty creative people out there. I found that a standard busman fuse on startup will heave and flex considerably and
it takes up to 45 minutes for that tiny wire to cool back down if it ever does without a shut down. Every time I've HEARD a difference
that was the case after paying a little closer attention.

When I bypass the fuse I accomplished the same thing. There is no recovery time for that little piece of shit to recover from.
I honestly think that most of the warm up time on equipment is because that fuse needs to cool down from a cold start. NO STANDBY.

That is the only way for me to be able to tell a difference after I thought I heard a difference. I retested over and over and found
as long as the fuse temp stays close to ambient there is no effect that cleaning the fuse holder wouldn't have accomplished.

I know that swapping a worn out fuses in speakers was the number one reason for poor performance in Infinity speakers.
100s were sold that needed nothing more than a saging fuse change and a fuse holder cleaned. Speaker cabling is the same way
it is as good as it is maintained. Green gunk is never good and cable that is constructed now vs 40 years ago are quite different.

Because I'm a old wore out nosy mechanic, I do what I do. I don't trust anyone or anything other than the dog, the rabbit and the chickens.

I suggest looking inside some of these construction marvels. The way the filament is tapered at one end and then attached to the
end caps without solder. The number of wraps for a slow blow and the tapered shaft is kind of interesting. They fill the barrel with
a heat dissipation fluid or a very fine dry medium. BOTH act a dampening fluid and a heat transfer medium. The barrel is not
a standard glass tube. Some have a sub strata wire coiled top to bottom over a ???? tube then shrink wrapped with ????

That goop on the end of the caps is usually a thick paste full of 2 or 3000 psi fine graphite. There is a reason for that. I first saw that
in the drilling equipment along with dampened fuses. It's a simple contact enhancer but it has a vibration quality that keeps the
fuse seated while using heavy fast top hammers. The wiring and fuses take a beating like nothing I've ever seen. I worked on some
serious vibration issues through the years. As my eastern EU peers would say "we need different gummy puffers"

Fuses in general work as intended. To protect the piece of gear. It has nothing to do with fires. If that were the case my vacuum cleaner
would have one. Not to mention my blender. Come to think of it my smaller Shark does have a thermal shut down. LOL

I have watched people install fuses that have all this fancy tech only to realize that putting a piece of 5N forged silver wire and the same with
forged copper 5N copper gave that same effect for 5 bucks. If I can justify 5 bucks in my Cary valve amps and NEVER had a problem. It's worth
it to me. I hate fuses and breakers until I smell Romex. That is what insurance is for. Oops did I say that?

Every piece of gear I use has 2 breakers and stick fuses or circuit breaker # 3. If it gets any safer it won't turn on without a combination.

Your guesses and intuitions about how a fuse can impact music have absolutely noting to do with science, or engineering.

Couldn't they at least use human earwax? Then you could say it sounded like you had a new set of ears......

… harvested from golden ears.

Please explain how one listens to a fuse... you serious?

And cant afford anythjng but a $500 dac and thinks it’s a Reference piece

Choose your words very carefully on this... I could purchase a $50K DAC if I wanted to, but that would be idiocy.

Oh, come on. Everyone knows this : You hold it close to your ear, and strike it with an exquisitely honed ingot of quantum field unobtanium.

And how idiots come by so much spare cash.

Likely inheritance or lottery winnings.

I have a box of fuses on my desk and they are silent. How does one listen to a fuse?

Ya put it in yer amp & listen through it, hey?

Now look! I literally answered this two posts before yours.

I thought maybe it was like candling.

Do these fuses have an UL or CE approvals? Any data on time-to-blow vs. overcurrent? I'm not sure I'd want a flammable substance around a device that likely creates quite an arc when it operates to protect the equipment it is in.

Re fuse only $100. Will not Re fuse your money. Guaranteed
No refunds

I should have known ,kids that don’t even know what tweaks are
And cant afford anythjng but a $500 dac and thinks it’s a Reference piece

Uh huh.

Count me me out .

Done.

I'm sure the manufacturer has dropped everything to get right on that.

/Uh huh

All their fuses are tested, right? That means any fuse I buy from them is pre-blown and known to work!

 

[fpitas]

I understand if you just send them money, your setup will still sound better.

Most people have no idea how little time the AC fuse conducts current in a power supply.

It conducts heavily for the short time the AC voltage peak is higher than what the reservoir caps are charged up to. I'm ignoring rectifier diode drops here. Draw more DC current out of the supply, and the conduction time gets longer. Still, overall, it's only a small portion of the AC cycle time.

Yes, in a properly designed linear PSU, we are talking maybe 5% of the cycle.
