Demagnatizing Phono Cartridges


I'm curious as to how many of the analogisti demagnatize their cartridges. What do you use and how often to you do it? Is this really essential -- is the magnetism a cumulative thing that palpably degrades sound?

I have an interesting question. If the coil wire is, say, copper, how does it get magnetized? Same with silver. I thought these metals to be non-magnetic.
Good point, Woodrow...

In any case, I have periodically demagnetized my cartridges using an Audioquest demagnetizer, most recently a Glider, and have to admit that I heard very little, if any, difference in the sound.
I have owned several Lyra cartridges, including my present favourite the Helikon. Scan Tech recommends frequent Demag for best performance. Presumably, it remains a matter of opinion.
