Help ! Best MC cartridge for Linn LP12?

Just back to first principles: I would match any cartridge, no matter what type, to its tonearm, without much regard for which table the two are mated with.  The only limitation with a spring-suspended chassis like the Linn's would be the weight of the tonearm and whether that constrains the choice of tonearm to go with the cartridge you may have in mind. I am no fan of Linn LP12, but I am not going to tell you to scrap it, if you like it. (EMT 927s are not readily available items, and only a few shops in the world seem to know how to restore/rebuild them properly; by all accounts, they are as finicky to get right as is a Linn LP12.)

In other words, I guess I find myself agreeing with Clearthink and Nandric.

As usual, we have LP12 naysayers who have never heard a fully decked out version. The Ekos SE ( while perhaps NOT the most resolving of arms) is a classic arm for the TT and is best suited for it weight wise. The arm can easily support the likes of the Etna and others...even heavy carts like a Benz LPSMR. The main criteria is how much noise you are going to get through your Janus Eclipse....and that has to do with the carts output, plain and simple. I would go with the Etna and call it a day.

Thanks Davey. I felt like mating to the arm was my first step- weight etc. I know dynavector XV 1-T/S supposely work well, as do The Delos, Skala,Etna etc. I was hoping someone could expand that list a little. Koetsu ? AirTight? Clear audio? As I said in OP, if I have the best pairing with the arm, then I can use that list as a good starting for compatibility w/ my phono stage. Then from those, I can listen to them individually (hopefully).   If the Better answer is upgrading my phono pre section, & sticking with my existing cartridge, I'd consider it. I'm trying to get the best source component and then  work outward.

I went from an AT33/ML OCC, which was a great cartridge, to a SS rebuilt Denon 103D, which is a superb cartrdige !  I use a Cinemag 3440 SUT.

Yes you can spend a lot more, but with something like the Denon, you would be at the point of diminishing returns.

Dynavector, Lyra, Transfig all work well on the Ekos ...It's a matter of what signature sound you are looking for. I am a firm believer in spending the $$ on a great phono stage and a great interconnect rather than on a cartridge which wears out. 
As you are a Skale user, I recommend you look into Tiger Paw's Tranquility- very significant upgrade for relatively small investment. As with all things LP12, a good technician is paramount to set up the deck properly. Seek one out if you are not very familiar with how the LP12 is assembled- this will make the biggest difference,imo.
The Tranquility is not a subtle change....
A really good interconnect from your phono pre to your preamp will also make a huge difference at the level of your deck- I use Chord Music and have been very happy with how little they do :)
