Funny you should mention the Ortofon cartridge

I have an Ortofon MC2000, the vintage MC with vanishingly low output. I was lowering it down on the platter of one of my DD turntables when it suddenly got sucked down flat onto the platter mat. Fortunately, the suspension took the hit and seems to be OK. I was using an LP-sized piece of TI Shield under the platter mat, to block EMI from the motor from causing issues with induced noise. Turns out TI Shield is partly ferrous and its ferrous layer was being magnetized by the underlying rotor of the DD motor. That was too close to the magnets of the Ortofon, and the two tried to kiss each other. This had never happened before with any other (non-Ortofon) cartridge. Later on, an Ortofon guru told me that they tend to place the magnet near the bottom of the cartridge body which makes it susceptible to this sort of accident. Maybe your problem with your Orto is of a similar nature. When I removed the TI Shield, the problem went away entirely.
