Upgrade from Rega Elys 2

The MoFi allows for either MM or MC. I don't mind playing around with the shims if it would make a tremendous difference. Getting to play around with things to get the best out of them is half the fun of having an analog system. 
Thanks again for the advice. 

Hello,
I’ve had a 2M Black on my Rega for a awhile and loved it. It has tons of detail, great dynamics, and generates a robust signal that lowers the perceived noise floor. All in all, a fantastic cart.

So here's the question:

Moving coil or moving magnet? Answering that question will (maybe) narrow down the choices. Also - shims to me aren't an issue (well - they might be - I've never dealt with them before - but I wouldn't mind fiddling with them). I just want compatibility with the tonearm / head I also told my wife that I'd be looking at a new cartridge and she didn't balk, so the search can move forward full speed ahead.

And I don't think that the Elys is bad - but I think the system is capable of quite a bit more and the source needle / cartridge is the easiest thing to change. 

Oranfoster,
On a Rega table, do all Ortofon 2M series cartridges require the same 2mm shim size?
