Cartridge "demagging"

bman
I just got a VDH Black Beauty about 4 months ago. I've had Audioquest cart demagger and Gryphon system dmagger for years. I stopped demaggin the cartridge. Van den Hul explains why you shouldn't and a lot more on his web site, most of which is over my liberal arts educated head. Cartridges are enough black art without me second guessing someone with the experience of Mr. VDH.

We've heard significant improvements after playing the frequency sweeps on the Cardas test LP. They are meant to demag a system, and it seems unlikely to THIS liberal arts educated head that playing a frequency sweep could do any harm. Of course I also don't understand how playing a frequency sweep would demagnify anything, but I'll not second guess someone with the experience of Mr. Cardas!

In the interest of full disclosure, a friend of mine tried the Cardas sweeps on his sytem and heard no difference. Maybe I majored in voodoo?

a)risk to destroy
b)if not destroyed, still no difference could be heard.
c)cartridge should normally be magnetized wether it's MM or MC.
