Help ! Best MC cartridge for Linn LP12?

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 :)
ATB,

I have set up many Linns with the Ekos tonearm - here are my suggestions

1. Invest in a wall shelf - this will lower the noise floor of your Linn over any floor mounted rack.
   
2. I would question your use of the Audioquest Leopard tonearm cable. To me it looks too stiff for the Linn suspension to operate optimally.
   
3. As far as cartridges go, the Ekos is quite versatile - I have set up many Koetsus ( including the stone bodied ), Decca, Van den Hul, Dynavector and Linn successfully to name a few. The only range I would avoid would be the Clearaudio’s. Given that you like rock the Koetsu’s may be a bit loose in the bottom end. Look at the reviews, your phono gain and system characteristics to find optimal match. If you don’t have enough gain you can easily loose dynamics.
   

I have to agree with the first poster veeyat. I’ve heard a fully decked out lp12, garrard 301, thorns All in custom plinths side by side in a friends system. All with very good arms and carts. All playing through a nagra pre driving 6 quad mono amps driving 6 quad (3 stack) else 57s. And to be frank the Lin just can’t compete with the garrard and thorns. Also on hand was a tricked out VIP with an air bearing arm that’s was lovely as well. I think your best bet is to sell the linn and move on. Hate to stir the pot here but. There is much Better out there for your money specially used. I build a garrard 301 as well after hearing his set up ditching a tricked out oracle Delphi mk 4 and couldn’t be happier

glennewdick, the system that you heard the 'fully decked' out LP12 is an interesting one....please do tell us what the 'fully decked' out LP12 consisted of? Hate to stir the pot here also, but I think one could safely say that a Quad 57 system driven by 6 Quad mono amps would be in of itself a little.... colored. I like the sound of the 57's--a lot, but the Quad mono amps were not the most 'resolving' IMHO, LOL.
