cartridge demagnetization


Are there any telltale signs that your phono cartridge [especially MC] needs to be demagnetized, or is this just a preventative maintenance issue?

Lyra carts such as the Delos use a paramagnetic grade of iron for the coil formers, i.e. will "conduct" magnetism but resist storing it, so residual magnetism should be minimal anyway?

I think you mean "soft magnetic" instead of paramagnetic.

Thanks for the constructive comment, Intactaudio.
I was looking for a word that described the properties of "soft" material but turns out paramagnetic wasn't it ;^)
Cheers,
