Is cartridge Demagnetizing Necessary?

• "You’re not fooling anyone by the way. Your system sounds so incredible because of the gate and mats and gray goo slathered all over the place. Which I know because, same here. Heh."

Correcto Mundo, Mi Amigo. For those who didn't get on that train, too bad for you. :-)

NO never.

Just don’t demagnetize a moving magnet cartridge, or you will have no magnet and no cartridge. The rest of it is up to you. I would never use a demagnetizer per se. I occasionally use the tracks on the Cardas test record which are specifically for demagnetizing.

Ironically, there is a business centered around routing the audio signal thru cables surrounded by powerful magnets. Go figure.

This is completely mistaken.
MM cartridges can be safely demagnetized - see the instruction manual for details. The Sumiko Fluxbuster manual specifically cautions against demagnetizing MM cartridges until the stylus assembly is removed first.

OK. Everyone should read the Sumiko Fluxbuster manual, because after all they have no agenda in the debate.  Bust all the flux you want.
