i have seen similar warnings on Van Den Hul site. I have never used one but since a cartridge is an electrical generator using a magnet, i do not know why you would want to "demagnetize" it

I used to have one of those Aesthetix units and stopped using it when I heard that it could be doing damage. So my new cartridge has never seen it. I also never really heard any improvement when I used it on my old cartridge.
Now I degauss my system by playing the Cardas Frequency Sweep LP once a week. That does make a noticeable and substantial improvement.
Cartridge demagnetizers have been around for decades. I remember the first time I used my old Sumiko Fluxbuster on a Dynavector 23R that had never been demagged. Really unbelievable improvement. AJ is well known for opposing the use of these things, so I wouldn't use it on his carts, but I've never seen others reporting damage -- that they could confirm from actual personal experience -- from it. IMHO, YMMV and all that.
