The effects of magnetic particulates in old carts makes one wonder if there is a...
We haven't established that there are any magnetic particulates. In fact, my conclusion is that it's unlikely. I've learned that cartridges get dusty, just like everything else. Over time, static charge plus moisture in the air or whatever, and those dust particles get stuck to the cartridge or cantilever. So, a little cleaning is in order (just like under the couch and on our records) to keep things tidy.
I definitely don't draw the conclusion that we should now replace cartridges regularly because metal is being stripped from the vinyl and attaching itself magnetically to the cartridge and cantilever.
Moonglum, I think you are trolling here. You've implied that the production of vinyl rubs metal particles off the "Tungsten steel grinder blades", which are then deposited in the non-virgin vinyl, which is then rubbed by the diamond needle, which pulls the metal out of the vinyl. And then, the "super strong magnet" in the cartridge sucks these particles to itself, like an electromagnet. And in the process, the cantilever grows to the point that it cannot move any longer. I assume you are also implying that the diamond is harder than the vinyl, even though the vinyl is strong enough to abrade Tungsten steel?
Next, I suppose you will tell me I need to lift the speaker cable off the floor to prevent static electricity from "smearing" the sound, and that some unnamed world-renowned genius thinks we should sprinkle diamond dust over tubes to make them sound more sparkly. JK... I don't wish to go there. Sarcastic humor.
This train is well off the tracks now...
