To clarify a few things about the LP12, years ago I used to work for an authorized Linn dealer and setup quite a few LP12's at and around the time the Cirkus upgrade came out. First, their were I believe a couple of changes to the original bearing. The last one was pretty substantial in that it had a bearing liner made of PEEK. A difficult (at the time) material to machine that created a tighter bearing tolerance. A much lower expansion/contraction coefficient. It was black and the oil was black. Linn also made the bearing and bearing shaft out of the same materials to keep expansion /contraction coefficients the same to keep tolerances from changing because of differing materials. Then the Cirkus bearing came out as a response to some owners dislike of the linn's mid bass performance or something like that. By the way their was a great article a few years earlier in Hifi News & Record Review about this very issue written by Martin Colloms where he figured out the (problem?) issue with a fix for it including measurements to backup his subjective impressions.
As far as the Cirkus upgrade went, while it took care of this mid bass bloat it also took away a lot of the character of the LP12 that made the LP12, I don't know, shine. I and quite a few others didn't care for the upgrade that daveyf gushed on about which leaves me to suspect that maybe his table had a more serious issue. I'm guessing. Not just customers but dealers who were quite familiar with the table personally didn't bother with the update.
Also the Majik and Kore (and Keel for that matter) are different sub-chassis' models made for the LP12. By the way if you own an earlier Linn like a Valhalla model you will need to update the sub-chassis to install the new main bearing.
Lately you don't hear much about LInn like in the golden era of audio. When I look at the LP12 I see a product with a lot of firsts in design and engineering. Mine is thirty odd years young and admittingly most of it has been changed. But after everything else in my setup that has been replaced, it has stood the test of time.
