The guru on fuses:

Fuses do affect performance.
When you replace an unstable resonant device a dangle dong contained  in a glass straw (description of a fuse) with a stable solid directional device, a magnet the increase in performance is incredible. Make your own comparison if you choose. Tom

please take my advice and find a corner wall. It will really help your condition :)

See what I mean?

replace an unstable resonant device a dangle dong contained in a glass straw (description of an AC fuse) with a stable solid directional device

Really!! to which "device" are you referring to, that is "directional" < > in an AC mains voltage path?? A diode?

Cheers George

A magnet has directionality built in and can follow the signal path in a circuit providing another enhancement. Tom

The old Fuse chestnut looms large agin--ha!

I tend to agree with George--the Bussmans/ Littlefuse etc do the job admirably .

The downside to the so called "Audiophile Fuses " that I"ve tried I gather most are Ceramic/composite filled, is they cannot accept the surges from some turn ons even at the correct rating.

Ones I've tried and they've failed more than once 

Synergistic Research--100 % fail rate especially with PSU's worst performers

AMR. Ditto above but easier on the wallet!

Hi Fi Tuning Supreme--50 % Fail rate

Furutech glory be!--100% OK-so far so good anyway.

Yes I feel we psych ourselves up to hear where our dosh has gone
when listening to the "Fuse"

Ah well we maybe are nutters!

Well George, you know I like you, right.. You haven't figured that VAC is doing the Cha Cha Cha, in a direction towards the source and then to a drain or ground. I'm no genius, as you can tell, but isn't that little friggin wire pretty important. Geez.. Think about that. 

It's not just "A"... it's a WHOLE lot more, Everything starts there and it CAN'T start without it... Right?

NO 150.00 is total BS, but as I said, there are some good 6-30.00 fuses that the stupid little wire filament, isn't made out of recycled Bear cans.. OK!!

64 VW vs 2021 VW ok.. different.. better...You got to quit being so friggen hard headed.. The earth is not flat...

I've been to Australia, the earth is round.. :-) Worked right on the Great Barrier Reef in 79.. Plane crash, cleanup.. Boom recovery ships, mechanics mate..1st class

All your answers prove you are delusional about ac mains fuses, especially them being "directional" in an ac mains flow, that "changes it’s direction" 60 x a second (60hz in the US and 50hz in Au) THAT"S WHY IT"S CALLED ALTERNATING CURRENT!!
You would have to pull the fuse in and out at the same rate (60 x a second) and not breaking ac <> flow to hear if were directional, that’s just how delusional you are.

On the boards George where they are directional. Tom

In the ac line where they are less resonant and have a much greater conductive surface area. Also a sonic benefit. Tom

Only one thing left for you

When they build an amp. or pre amp or what ever, aren’t better components, BETTER?. Look at the copper foil resistors, I thought WIMA caps were the reason for the great but reasonable cost of HIGH quality sound... It’s not, it the resistors.. AND they do make a huge difference in SQ..

SO WHY are you so resistant to a damn fuse... Beyond me.. I don’t get it..

Every time I use this fuel my car does this.. OK, do you like what it does?
NO, pings like a pong! Sounds like it’s gonna blow up... Answer. don’t use that fuel. BUT I use this other fuel and it runs even better, same octane. What do I do.. REALLY? oh by all means use the crap fuel...

I dunno... maybe I’m just too emotional.. about the whole thing...LOL
Go hug my speakers... They know they get the best...

Regards..

Knot Cuckoo vs Ignorant..Tom

Never had one fail.

I had my ARC Sp10 fail in 1989 when it caught on fire before the fuse blew I was able to unplug it..
Tom

Why oldhvy because for all the bs about an amp just modulating the power supply, the reality is what makes for a stable supply and the properties assigned to audiophile fuses are not the same. It's all a smoke screen of ignorance.  Fuses feed into 10s or more feet of wire in a transformer and high inductance. Conveniently forgotten. A fuse that increases in resistance as it heats up (more current) would make for a more stable supply voltage. Yet people go gaga over low resistance. That is what happens when people who don't understand amps and power supplies make conclusions based on suggestion.

Same for speakers and low current draw dacs....right?? Tom

I just like the way it sound, nothing to do with anything, Scientific. LOL

Mercy

That last part of your statement, lends it’s self to a previous comment about a twisty flat 99.99 copper flat ribbon, with .0X increase per meter resistance. It is not just R, C, and end load, is it?

That silly little filament, yea buy the cheap one, by all means
Recycled German cars make better fuses than recycled Korean cars.. That’s all I’m saying.. :-)

I’ll stick with my 6-30.00 fuses and my FREE SR fuses..
YES I use Busman where it sounds no different.

I sure would have liked to work with some of you fellas’.
I personally like breakers, or bypass the fuse all together in stereo gear, or speakers (they always go, speaker fuses)

I’ve NEVER had a problem. BUT I've had GREAT success with speakers and shi$s fuses in the path. Infinitys ALL OF THEM. I've owned  LOT of them.

YET I did a speaker cable drop that blew up all kinds of stuff. The 20 amp main breaker blew, but not the 5 amp slow blow in the VTL or the Mac 275. The stupid class d, never missed a beat.
Two months after that, the Mac C2500 Pre lost a right channel.

A cable drop... The ONLY one I’ve ever had, 15K if I would have just replaced the components.

The busman did not blow...in ANY of the pieces, all failed. SAFTY??? 3 right channels!!
That is the exact reason I tried SR fuses, I though what the heck, I was using ACME, and Tuners. They sounded better in my (Samra) C20. I used a FREE SR FUSE.. LOL

BTW want to buy a pair of 300 Deluxe VTLs, perfect except the signal caps are burnt off circuit board.. Busman fuses, ay? Safety?

Nothing safe about them as far a equipment. Especially slow blows. Friggin’ junk. Mechanic NEVER use them EVER... Breakers ONLY,  or standard fuses, some fast blows.. (Computer fuses).

Like I’ve always said, "Stereo equipment is NOT rocket science", it is really kind of simple, compared to a modern day piece of equipment. EVEN a friggn lawn mower is more sophisticated by design.. WAY MORE or mower. LOL

I used magnets only for test bench purposes and never in my permanent rig installed at home or around other living beings.  Tom

@georgelofi,  Wow, interesting business model you have there conning your customers. Do you sleep well at night?  We all know you can't hear the difference so why oh why do you need to waste our time with your insulting negativity.

Fuses feed into 10s or more feet of wire in a transformer and high inductance. Conveniently forgotten.

So do power cords and anyone with a working set of ears can hear the differences they make.

All this wire after the fuse is just another variation on the old, all those miles of wire before it gets to your outlet BS: another red herring.

All the best,
Nonoise

We all know you can’t hear the difference so why oh why do you need to waste our time with your insulting negativity.

To counter the snake oil, voodoo, BS told here by shilling fusers.

Seeing it's the Chinese New Year of the Ox, everything needs the real Yang told to any BS’ing Ying.

I did the fuse and magnet demo for my they don't care daughters and 2 grandsons.
They couldnt understand why others denied hearing any difference when it was so huge to the 4 of them. The 9 year old grandson described those that say they couldn't hear a difference like that of him trying speak to his 91 yr.old  grandmother standing at her face and speaking very loudly..nearly deaf. Tom

I made this comparison on my work bench system only. 

The difference was so great that .....


I like this new audiophile joke. Good twist on not using the wife for once. That was getting tired.

Nonoise that is a silly position to take. The fuse literally just an extension of all the wire in the transformer. There is no node in between. This is much different from the "miles of wire" before the amp argument as all there is a node where all the units connect together as well as a case grounding node and the potential for ground / neutral interaction.  A fuse is just an extension of the wire in a linear supply transformer and perhaps some resistance in front of a switch mode (rarely a bad thing).


Attempting to equate these two things only shows your lack of knowledge and proves my point about who advocates for fuses.

So 2 design are you say I am lying ?
Rod magnets are about as cheap as the wine you drink, 2 bucks each. 
Set up your own demo and listen in the room or close the door and go into an adjacent room and listen or go to the bath room you will be able to hear the difference over those noises also. Well in your case maybe not.

Tom

Attempting to equate these two things only shows your lack of knowledge and proves my point about who advocates for fuses.

He's probably the dumbest of all the fusers here, as he "tries to justify" his stupidity.
Cheers George

Nonoise that is a silly position to take.

And yet you took it and are still running with it.
 
You're new schtick of the old "I'm rubber and you're glue" is a pleasure to behold.

All the best,
Nonoise

Nonoise you are only justifying george's statement about you. You made the comparison. It was a really bad one. Own it.

audio2design, now you're down there with good ol' Georgie, in that rarified mud. Your two can be bunkmates. Feels like home, doesn't it?

All the best,
Nonoise

A danger 2audio..you and George
are afraid to make my fuse comparison. Tom

02-13-2021 5:12pmSo tweak, was that a ceramic magnet? Neodymium? Nickel coated? Stainless steel coated? 5*25? 1/4x1-1/4? But more importantly why do you hate children so much? Mom! Grandpa’s making us do weird stuff again!!! Do we have to go?

Neo n45..nickle plated ..gold plated would be better because of its lower shear velocity..you guys should study up on material science and how shear velocity is a major part of all material sounds.
Good luck. Tom

Shear is in all shapes and materials just look around. You are blind to sound even when its in front of you. Think of that ugly reflection in your mirror and how that surface feeds back sound. Electronics can not overcome poor choices of material shapes and boundaries. Better choices come first.

Only the magnets are plated. For 1 of my patents I remove material to add more reactive materials to make the device operate at its prime resonance point of contact. So by broad definition, the contents of the device are plated over. Shallow plating applies to your imagination. Tom

You pretty much just proved my point. When you only tool is a hammer, every problem is a nail.  From another discussion I am not even sure you know what shear velocity is.

Thanks for bringing up the point because that geometry is a part of one of my patents. Go Fish. Tom 

I am guessing not awarded patents.

@georgelofi : you state,

"He's probably the dumbest of all the fusers here, as he "tries to justify" his stupidity".

Good one georgie boy, advocating for displaying stupidity with reckless abandon.

What you need to strive for is 'wreck-less' regarding the damage you do to a thread!

@danvignau - thanks for the link to the article, I've not seen that before.

The fuse he was talking about was in the speaker circuit, not the power circuit.

+1 @audio2design. 

The text on page 6 refers to protection of the amplifier outputs i.e. the signal that goes to the loudspeakers. There needs to be protection at this point in case a fault in the amplifier sends DC to the loudspeaker drivers, which can result in quite spectacular failure. Loudspeaker protection needs to be very fast (milliseconds) which means any fuse would need to be rated very close to the maximum operating current of the outputs and it would heat up in normal use creating distortion.
Most (if not all) amplifier manufacturers use alternative methods to protect the output... I use relays, others use transistors etc.

The fuses that most people in this thread are referring to are power supply fuses which will not heat up in normal operation and can be rated with comfortable headroom above the normal operating current. These do not form part of the discussion in the article.

Thanks.  I had not considered that people are discussing inline speaker fuses.  I still wonder if most people are.  I did use fuses to protect my stacked Advents from my Phase Linear 400.  A dropped tonearm always blew them. 

danger2audio you are as wrong as usual. Tom

I am curiously noting that you're not providing any links :-)

I already have. Tom

Sorry can't find a link you provided anywhere. Saw you mention a design patent but that is not a functional patent (for what it does) only what it looks like.

 I have more than 1 type of patent. A design patent is functional when it obviously works. You can see that with the illustrations.
Tom

That is not how design patents work. You either have a design patent, a utility patent or both. You said design patent and again I found no links. Design patents don't protect the function:

From USPTO

In general terms, a "utility patent" protects the way an article is used and works (35 U.S.C. 101), while a "design patent" protects the way an article looks (35 U.S.C. 171). ... Both design and utility patents may be obtained on an article if invention resides both in its utility and ornamental appearance.

I have utility and design patents.
And I know how both offer protection. happy valentine..Tom

Still no links.

He's full of it, typical fuser crap.
Cheers George
