Going from MM to MC

I have a linn table with an akito2 arm I just replaced the preamp with a rogue rp7 and bought a pro ject phono box DS3B phono preamp.  I am also going to get new phono cable from linn with the xlr ends on it. Right now I have an adikt on my table. I want to go to MC  to get better detail and seperation. I have been researching Cartridges and have narrowed it down to 3  the linn Krystal the lyra delso or the ortofon quintet S black. My Lin repair person is trying to get me to go  with the linn but I have herd the other 2 have better sound  any advice.where to go or even a different one all together  and why thank you Michael.
