Cartridge Demagnetization

I will repeat:
Do NOT de-magnetize any cartridge.
People are in doubt of the reliability of my statement because I'm the first to state so on page 1.
That's typical on any HiFi forum.
TobascoKid did a well explained post of why NOT to de-magnetize cartridges, supporting my statement.
No reason whatsoever to shortcut the wires either.
Don't start using a Zerostat gun on your cartridge either.
Don't put your loudspeaker in the laundry machine.
Don't dry your dog in the microwave.

Cartridge Dema...
Hi
I'm with niklasthedol on this one. Never owned a demag device and I don't intend to either. Surely, somewhere in the literature that came with the cart, it would have recommended demag if and as required?
Btw, I have found all kinds of the most unlikely substances are attracted by a strong magnet if the attractee is of sufficiently small mass. 6N copper of 47awg curl any which way if you hold two ends together as the 'poles' repell eachother. Hell, even slivers of hardened superglue are attracted by a strong neodymium magnet. Vinyl discs are magnetic too as they 'grab' iron particles from dust in the air and re-deposits them on the underside of your cartridge.
I fail to understand the logic behind demagging a cart as they NEED a magnet to work.

I DO have a de-fluxer as the unit for de-magnetizing also is called.
Or I have several as a matter of fact.
But that is for use on my Cassette and R2R decks solely and has to used in a certain way not to cause damage.
Her we go, even if it's off topic here.
Quotation of myself in thread with a debate of using wand type or cassette type de-fluxer:
"The de-fluxer in cassette shell is not recommendable.
The wand type is the one to get.
You can damage your deck if you de-mag with wrong procedure.
Clean your deck first.
Get tapes away from within several meters from the area you are using the de-fluxer.
Make sure the de-fluxer's tip is covered with rubber or plastic.
Turn off your deck.
Make the tape path accessible.
Position some magnetic material approximately 1 - 1½ meter from the deck.
Turn your de-fluxer on at the point of the magnetic material you put 1-1½ meters away from deck.
Slowly move the de-fluxer closer to the deck.
When at the deck, very slowly let the de-fluxer demagnetize all metal parts in the tape path.
Do not let the de-fluxer touch any parts on the deck.
After passing the last point of the tape path, slowly drag the de-fluxer away in the same tempo in which you approached the deck before.
When the de-fluxer is back at the magnetic material at 1-1½ meters away from the deck you can turn it off again.
Get the magnetic material far away from your gear now.
The basement, some shelter in the garden or throw it over the living fence in to the neighbour.
;-)
Done this way, no harm is done to your deck and it will be properly de-magnetized.
The reason for avoiding those de-fluxers build into a cassette shell is that the machine has to run to activate the device.
Having the machine on when de-magnetizing can or might severely damage it.
I question how to de-magnetize other parts in the tape path with the cassette type de-fluxer unless you take it apart and activate it manualy while the coil is handheld.
On the wand type de-fluxer of mine, the instruction clearly states: "Langsamdie Löschdrossel auf 0,5-1 meter entfernenund dann erst durch Herausziehen des Steckers ausschalten"
This is translated that you have to take de-fluxer 0,5-1 meter away from the tape path that you just demagnetized before you pull the plugg on the device.
How will you do that with a cassette type de-fluxer?
So conclusion is:
Use the wand type when de-magnetizing.
I am not saying the Radio Shack Cassette type De-Fluxer did any damage.
It might have, though."
Quote end.
And don't demagnetize anything but the described.

****, now you tell me.....
Very simple:
A MM, Moving Magnet, cartridge contains a Magnet that has and is supposed to remain magnetic.
If you try to demagnetize this, and you succeed in this, the magnetism in the cartridge will decrease, and the output created by the magnet in conjunction with a steady coil, will fall.

That didnt answer my question. Im asking about mounting hardware Dolph, not if I should demagnatize or not.

How bout putting a magnetizer and a demagnetizer in opposite corners and let them fight it out?
Can the dog go in the laundry? Arf.
I'm getting tired of the "new ways to improve your life through audio" gimmicks. At some point, as I have recommended before, it's time to listen to the music instead of the equipment. A system doesn't need to be in the six-digit price range to be good.

i also have the Aesthetix demagnetizer, and i use it on all my MC cartridges:...
Denon DL-103
Denon DL-110
Sumiko Talisman-S
and vinyl1 is correct....you only demagnetize an MC cartridge....never a MM cartridge.
one last thing.....if you're in the DO NOT DEMAGNETIZE corner, fine, but don't trash those who believe demagnetizing is beneficial. if demagnetizers were such a bad idea or somehow bad for the cartridge, they would be summarily shunned.
I did what the guy in the video showed. I just wish I would have had someone here who could have done a blind test. Over the years, having heard just about every sales reps' tales of how great things are and why, I have made every effort to be as objective as possible before passing judgment. If I hear something that seem ridiculous, I'll either ask someone who's deeply into electronics or physics. I don't just haul off and condemn something immediately. I have heard differences in cabling, tubes, caps, speakers, room treatments, etc. I'm all for things that make a system sound or look better (video quality) but if a stylus has an assembly that can become magnetized, it strikes me as a design that doesn't address all of the details. Is it possible that the output could decrease because of doing this? Maybe. A coil with an iron core has different magnetic characteristics than one with a non-ferrous core and I have to wonder why they would use a material that can become magnetized in the first place. I was genuinely curious to find out if this would work and in my system, I didn't notice anything but as I mentioned, I would like to have been able to do it blind. Also, before anyone tells me that my system may not be adequate for revealing the difference or that my ears are shot, I wear ear plugs in loud places and always have a set with me, I have been tested and have better than average high frequency acuity (sometimes very annoying) and my speakers reveal a lot of things about recordings that I would sometimes prefer they couldn't. It could well be that the cable I used to replace the ones original to the turntable aren't as good as described but since I also have a Denon 103d (is your an older or newer one?), I think I should have heard something afterward.
As far as recommendations that are bad ideas or bad for the equipment- I have seen and heard many recommendations in my 30+ years in the audio business that were either, or both of these. That's why I prefer to remain as objective as possible. If I hear a difference, great. If I don't, that's OK, too.
Nope.
They just degrade output level.................one day, maybe, there's no more signal.
Whatever?
