I have had my MC cartridge for about 5 years. I haven't kept a proper log but I would guess about 7-800 hrs. How can I tell BY LISTENING that it is worn enough to replace or retip? Does it get edgy or shrill or....? I suspect that the change would be so gradual that it might be hard to tell, as the ear slowly accomodates. Of course I should remove the cartridge and view under a microscope but un mounting and remounting is a perilous business that I would like to avoid.
Dear @don_c55 : "
I have old records played many times on cheap old MM cartridges from the early 70’s that sound "mint" with expensive properly setup MC cartridges of today. "
in those old times cartridge stylus tip was conical that let the deep information recorded in the grooves " untouchable " , so are as " new " and with line contact shapes that information comes alive for the very first time. Yes, LP surface is resistent to the stylus tip very hard friction. Now, that for whatever reasons we are not aware either the stylus tip wear levels or LP surface damages does not means is happening each time we use that cartridge and any LP. My take is to try stay " always " in a safe umbral.
Btw, @boxer12, I listen both sourcves but a little more on analog. I own 100+ MM/MC cartridges and normally I don't stick with one of them but more rotating . I still own cartridges that I never tested yet.
