Looking for a cartridge upgrade

I am currently using a Linn Krystal Cartridge on my LP 12.  I am looking for something with more punch and dynamics.  I listen to rock, blues, jazz and country.  The rest of my system is Audio Research and Wilson.  Also, anybody out there try the (not so) new bearing upgrade on the LP 12?  I may spring for that when I upgrade the cartridge.

Thanks for the advice!!
