I had pretty much the same rig as you (since upgraded to TNT HR5), and found the Benz Ruby a very nice upgrade. Like the Grado, warm and inviting, but with loads of detail. You can get it for $2,000 with ANY trade-in (e.g., any old, cheap cartridge you have lying around -- no need to give them your Grado).
MC Cartridge upgrade from Grado reference?
I need some advice on a cartridge upgrade. I currently have a Grado Staement Refence (.5mv) and would like to try a good MC. I was thinking the Shelter 901 would be the one to go for. I then started reading here on Agone and I am finding out it may not be the best match for my tonearm/TT. Any suggestions for 2k or under? The Helicon, for instance, seems to be held in a little less esteem than it once was (especially compared to the Shelter). How about Koetsu, ZYX........... (or stick with Grado (Statement????))
Current rig is: VPI Aries, JMW 10, ARC Ref. phono
