cartridge demagnetization


Are there any telltale signs that your phono cartridge [especially MC] needs to be demagnetized, or is this just a preventative maintenance issue?

Hi

I use this method every 100 or so hours with my Benz Wood SL and it works great.

I have done demags on well over 100 cartridges without any problems. It has always worked. I did once accidentally demag a MM cartridge and it completely ruined it, so be careful.

The tell-tale signs that it needs to be done is a loss of high frequencies, soft, flat overall sound with a lack of dynamics. No sparkle. Demaging will usually bring all of this back.
Thanks for all the input; Czbbcl: I did watch that video on UTube. Does anyone not agree that method is safe and effective?
In that YouTube video, it really isn't a demag, it's a deflux. Not the same thing, but I'm sure it won't harm anything and could be worth a try.

If it was a real demag, the MM cartridges he claims also benefit from this treatment, would be ruined.
