MC demagnetizer, how many use one, any concerns?

To all who have answered thanks very much. I appreciate both points of view. I plan on trying it but recognize that this is not something that is likely to lend itself to any sort of a/b comparison. Since it will take several days for the cartridge to settle in again it will be impossible to remember what it sounded like prior but I will give it a go, and for what its worth leave my impressions. If possible I will do so with a few friends. One final question is do you hook it up through your phono cable or directly to the arm output. Again thanks a lot this has been a lot of help

I think there will likely be conflicting comments on this but would make a few points having begun this thread. First, I have noticed quite a bit of improvement in my cartridge since using the demagnetizer. The sound muddies a bit for a few lps and is then quite a bit more focused but very natural. Second, I don't use it weekly but probably every few months as part of regular turntable maintennance. Third, I wonder about the damage it can do to a mc cartridge given that the manufacturer of my cartridge recommends it (though you could say cynically that way they sell more). Fourth, of all the people I have talked to that have used them none have noted any problems. Finally, if I'm not mistaken a number of very high end phono stages, I believe the boulder and the rhea, include demagnetizers. I doubt they would include something that would worsen the sound in their opinion. Having said that if you have worries don't use it just enjoy your music.
