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?

The Cardas Sweep Record is the cheapest method; once a month or so, and yes, you will hear the difference. On a moving coil cartridge;more silent background is noticed. I actually alternate with a Fluxbuster.
Aesthetix Demagnitizer works wonders. It should be done about once every other month and with the arm in the play position so that there is weight on the stylus--this should center the coil (MC). I've heard that using this while playing the cardas sweep record is even better. Haven't tried it yet, but I intend to.
Thanks, guys. I am familiar with the Aesthetix and while I have heard of the Cardas sweep record I have no idea how it works. Sounds like doing both would be just the right amount of "overkill" for me. Most Benz Micro cartridges have been backordered from their distributor but they are supposed to get a shipment this week. I'm hoping to have my new/old Oracle set up soon. I guess I can wait a few weeks to get de-magnatized. Thanks again.
