Dear friends: I had bad/good experiences with active demagnetizing using the Sumiko Fluxbuster.
It works very well with the old Koetsu's and moving magnet cartridges. I use too with many others cartridges type and I can't perceive any better sound reproduction changes. But two of my cartridges were damaged for this demagnetizing: Clearaudio and Allaerts, what happen?: I do the demagnetizing cicle and the cartridge works for a week or two and suddenly one of their chanels go out of work: the coil wire was broken ( do to the demagnetizing ).
So be carefully about.
BTW, Ortofon told me this about demagnetizing: " remember that demagnetizing a cartridge with NON-MAGNETIC armature has NO SENSE.... ". Anyway, the best any can do about is to ask to the cartridge manufacturer.
Regards and enjoy the music.
Raul.
