I am plenty happy with my LP12- next yer will be my 25th year owning it. Anyone who says the LP12 easily drifts out of adjustment has not had experience with an LP12 in at least 30 years. Frankly, one of the more remarkable improvements over the years to the LP12 was relatively recently- the Karousel bearing. And as it costs less than what many spend on a cartridge, yeah, it’s a great addition to the LP12.
No one is saying keeping an LP12 in current form is cheap. It’s not. But a great deal of high end audio gear isn’t cheap either.
What I don’t understand is why so many get butt hurt by the fact that a number of us really like our LP12’s. Shall we argue about ice cream flavors next?
