How often do you demagnitize your MC cartridge?

Do not do it. Cross-ground them and play them for 30 sec. It WILL accomplishe all clearly auditable benefits and you will be all set to go for another couple weeks.

YA! What he said, sstark@carolina.rr.com, it's very important to be done immediately, but that would be the only time necessary.

I demagnetize my Lyra Helikon, occasionally (every 6 months or so). The improvements are noticeable. It is also recommended by the manufacturer.

For those who have not tried it, how can you be so certain that it will have negative effects? I have demagnetized many MC cartridges over the years without any negative side effects.

G morris What do you use? how is that sweep LP any good?
you da man

Rockinroni:

I am using the Audioquest battery operated demagnetizer (it was about $70). I have not used the sweep LP, so I cannot provide any first hand information.
