What are you after? Before I purchased a 2nd hand LP12, I had a number of turntables which just did not sound good but incrementally got better. Obviously I had heard turntables at dealers/shows that made me realise better vinyl sound was possible. But my 1st LP12 purchase was the turntable that made me realise I had achieved what I needed at home. That was back in the early 90s when an LP12/Naim fanatic helped me in this purchase. Pre Cirkus, Ittok arm, K9 cartridge, Valhalla. Since then, other than cartridge, the only changes I have made was to remove the baseboard (cleans the bass), and add a 33/45 speed change option in the shape of a Manticore 5i electronic speed changer (and that was years ago), just because the Valhalla didn't do 45. I have never ever felt the need to make any other 'improvements' or 'upgrades', unlike digital sound, where I have constantly tried different transport/DAC combinations (but eventually always come back to a 1990s combination - but that's a different story ) . If you want an LP12, there is probably no right/wrong combination. Base it on what you want to spend but more importantly what you want to hear. Try and stay with Linn 'upgrades' if you want a typical Linn sound. That may sound obvious but I personally think some 3rd party upgrades alter that.
