Upgrade from Rega Elys 2

The 2M Bronze is one I've looked at. I'm sure that there'll be upgrades to the system along the way. The hard part is staying in budget. I appreciate the advice. 

My tastes lean more toward the warmer, but it depends on the instrument that's the most prominent and that I'd like to hear the most clearly. The black is within the upper stretches of the budget at this point. I'll look at the Nagaoka as well. 

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. 

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. 

WillieWonka - those are some tempting upgrades. After talking with my dealer (I live across the country from the folks I've been using but they've been stellar), I'm going to get the TT up and on the wall with a wall bracket / shelf, obtain an after-market cork or other mat (the felt is a freaking dust and static charge magnet), do some more isolation of the other equipment, think about power cable upgrades (TT and amp) and then look at either a new cartridge and/or tonearm set-up. I'm just getting into the mid-fi game and have kids to put through college, so although there's a lot of room to improve, the steps will have to be small / incremental. 

As the P3 is brand new, I can't justify a complete replacement at the moment. The suggestions, however, are duly noted inna and schubert. 

The Nottinghams are slick-looking and may be on the list of upgrades in the future. The problem is I'm in the central US, they're a UK company, and auditioning such a beauty would be near-impossible. 

Got it - thanks ericsch. Inna - I'll keep that in mind going forward. I have a feeling that, as much as I like to listen, this will have a snowball effect, but rolling uphill (as cost goes).
