Is de-magnetizing the cartridge too often damaging?

Loop4fun and I have been chatting about a question I have. Is running a de-magnetizer every quarter or so (or at all) damaging to the cartridge (immediately or over time?) It seems I read somewhere that it could be but have nothing definitive on the subject. I have a Sumiko demagnetizer and a Sumiko Blackbird cartridge for reference. Thanks. Larry:S
 
Wow...almost afraid to answer...LOL

If its a MM cart...you will ruin it.

For MC carts, some say every 1000 hours, some say often. There is a paper that says because of the realignment of the magnetism, the more you do, the more you have to, so don't do it...

I would say (opinion) leave it alone...read up VanDe Hul
 
We used this at Bobs (rhapsody NYC) . Listened to a song then demagnetized the cartridge and then listened to the same song. There was an obvious difference. It definitely does work.
About 5 of us were there and all were surprised at how good it worked . I wouldn't even think about it for like a year on a new cart.

Here some dialog from J. Carr of Lyra from 2001 http://www.audioasylum.com/audio/vinyl/messages/61192.html..... If you do some digging around you'll find mixed opinions from the various manufactures......I fall into the camp of not doing it.

That's the one I always refer too also :)

I always suggest contacting the manufacturer. Some such as AJ van den Hul don't like demagging and a friend of mine swears demagging did in his Shelter. I've always demagged my Lyras and a few others without any issue using the old Audio Physics device thar Allen Perkins used to carry. Way better than the old Sumiko Fluxbuster.
 
I may have to sell my TT WEIGHTS outer ring.
On the Verdier table, it seems that it gets magnetized and passes it to the carts. This creates a hum / buzz with a length of about 5 secondes and coming back every 3 seconds, like if someone would blow on it !
I spent weeks thinking about a bad tube in my phono stage !
Never thought about demagnetizing carts until now.

I am with Jeff...funny, one of my test records has a track that you play 10 times and not only tests but demagnetizes due to the frequency..

its this one
Ultimate Analogue Test LP

Side 2
Track 2 Pink noise lateral
Track 3 Pink noise vertical
Used for cartridge “demagnetizing”
You can also use this track to loosen up the cantilever’s suspension to help break in a new cartridge. Play these tracks five to ten times after every 300 hours of normal LP playback.

Playing that track ten times would sway me to spin a cd :)

What do you think so far Larry?
