We Need A Separate Forum for Fuses


LOL, I'll bet I gotcha on that Title! ;)  BTW, I put this thread under "Tech Talk" category as it involves the system physically, not tangentially. 

More seriously, two question survey:

1. Do you think designer fuses are A) a Gift to audiophiles, or B) Snake Oil 

2. Have you ever tried them?  Yes or No

In the tradition of such questions on Agon, I'll weigh in as we go along... 
Feel free to discuss and rant all you wish, but I would like to see clear answers to the questions. :)

I, personally would never bother to upgrade the OEM fuse in any actual electronic equipment. Digging around to find them, then the correct rating.. Too much bother.
However my speakers (Magnepan) have fuses in the signal path for midrange and tweeter.
In those locations I have used aftermarket fuses. I have also bypassed them to achieve even better results.
I have no ax to grind for those who do like to swap fuses in electronics.

Geoff.and perhaps Al... I wonder if part of the directionality of fuses is caused by subtle magnetic fields around each particular application?
Folks talk about the resistance, impedance and inductance of wire.

But one factor not mentioned is the always present magnetic fields.
So I wonder if anyone has done some research on them. There are a few IC which play with magnets, but I would think a lot more could be done.
Also trying to degauss Fuse clips?
Anyway, this thought has been in my mind since my new 20.7 Magnepan Tweeter problem happened.
(in which one channel tweeter wiring was reversed, causing that tweeter to barely make any sound. Until the physical tweeter was inverted. Then it played, However Magnepan is going to replace the speakers The odd thing is the directionality. Why, And I can only account for it by saying the long magnetic field of the tweeter somehow has a polarity,even with AC music waveform. And no it is not the interaction with the midrange, which had the midrange fuse pulled anyway.) I also wonder if the near silent tweeter was getting hotter, The music energy had to be dissipated somehow, but I do not have a digital thermometer.
Also two separate tweeter elements were tried, both behave the same way when sonnected wrong. (the magnepan tweeter is a long strip full of magnets, one terminal at each end, connecting the mylar and foil tweeter ribbon which is surrounded by the magnetic field.)
So I suddenly have been thinking what else could be affected by magnetic fields in my stereo?

Also I have to say a fellow emailed me about my tweeter, and it got me interested. so any credit has to go to some other person who thought it was more than a simple thing.
Anyway, your thoughts?
(I was too late to be able to add to my prior post so...)
An additional though about the subtle ways magnetism affects audiophile sound is the de-magnification of LPs and CDs. Folks find improvements in the sound from this process. So there seem to be plenty of room for experimentation in the area of magnetic fields and audio affects.
I still own a pencil Tape head demagnitizer, and plan on buying some horseshoe magnets to magnetize the fuse holders, then demagnetize and switch the field to see if I an notice any effects on the sound for my fuses in the speakers. (though I am going to wait since the speakers are still going to need breaking it.
(so anyone wanting to do some experiments I have no problem you beating me to any discoveries!)
Contact enhancers would thus also make an improvement on a fuse. Creating a greater area of contact.
(I do not own a meter with sensitive enough readings to tell me when a fuse would be rotated to the lowest resistance..)
I like Caig Pro Gold myself. Though the caveat about leaving only a trace to do the job is important to not have the connection degrade over time due to the 'more is NOT better' truth.
I have never tried some of the 'wonder' sorts of contact enhancers.

I would agree with the contact being a part of the equation. Though I would not say it in any way rules out other aspects.
Though some folks would want it to, it really does not negate any other claims. Only points out one side of the problem.

And it leaves nothing for the facts of the way the Magnepan tweeter behaved. Which is IMO still a great mystery...
(I would hope some other brave Magnepan owner would try reversing a 5 ft long tweeter element and report back. Seems folks just do not believe one lone report on it.)
"Worldview and unspoken priorities/principles"
Yes. I would agree the 'preconceived notions' rules many of the attack comments.
When folks Worldview is being challenged, plenty of folks would rather attack, or insult, rather than question their own beliefs. And even become adamant about it, As if arguing harder props up their own shaky ground.
The most telling about that attitude is all the folks who USED TO be 'non-believers' in wires and fuses etc. Who, after finally hearing the difference, revised their views. Plenty of them, including me.
(though I would be hard pressed to buy more than the minimum aftermarket expensive powercords or duplex!)
Good thing I keep most of my equipment on 24/7/365.
My amp which is now 8 years old has been cycled off back to on at most a few dozen times..
No worry about those fuses going bad.
