MC Cartridge Degaussing Demagnetizing


An old topic that I would like to re-visit and would appreciate Jonathan Carr weighing in on.

What does LYRA use and/or recommend to degauss their (MC) cartridges?

What happened to the Audio Physic demagnetizer?
Immedia seems to have dropped them.

Since many companies/manufacturers of phono carts will NOT discuss degaussing their carts and/or the material of the armature is it OK to use the Cardas or Analogue Productions LPs instead?

How EXACTLY do these sweep records degauss a cartridge?

Is it OK to assume that IF a sweep record helps a cartridge sound better then a degausser or demagnetizer is appropriate?

Assuming no DC content and a very low level voltage and current... How EXACTLY can an AC rising and then falling signal fed into the cartridge cause the cartridge to fail prematurely?

Thanks! :^)

I have a Fluxbuster (old) and use it about every month or so. It DOES make a difference on my Benz Ebony LP. Some cartridge manufacturers don't approve of it because they use wire that connects the pins to the coil that is so thin and delicate, that they are fearful that they can melt or be burned by the demagging device. I know that Benz recommends it for their cartridges. Check with the manufacturer of yours for clarity.
Regarding Fluxbusting.... When you turn on the device, it does its job and then stops. The end of cycle is the actual turning off the unit and then switching to the other half of the cartridge to demag that. What I do is disconnect the unit from the cartridge when it stops demaging and THEN turn it to the other half after disconnecting it...that way I do not get the "metalic sound" you describe.
