A new Question: Moving Magnet Cartridge To Compliment My Rock Collection


I am looking for a MM cartridge to work well with my VPI Prime Turntable with the 3D arm and to compliment my large Rock collection.  Presently I have a ZU/Denon DL103 MC cartridge with a bent canteliver.  I will be sending it to Soundsmith for repair and keep it as a spare.  My Rogue tube preamp accepts MC and MM cartridges.  I want to keep this in the 500-600 range new and cheaper if used.  Recommendations and why?
128x128stereo5
I am wondering about the new MoFi ultra tracker mm cartridge.  I believe it is 500.00 new.  There isn't too much information out there on these new cartridges.  I wonder if they are  all the same cartridge, just different stylus tips?
Goldring 1042. Why? Because I myself use it with Nottingham Spacedeck/Spacearm. It does jazzrock like hell. If it works with your arm. Get it from the UK - analogueseduction.net or the US - lpgear.com. Nagaoka 500 should be great too, probably a bit more refined and smooth.
London Gold. Very dynamic, lots of bass, somewhat "forward" sounding (I prefer to think of it as immediacy and presence), high output (5mV !), great for Rock ’n’ Roll.
The only MM I have and it sounds great with rock, blues, sole and jazz on my 3D arm is an old school Grace F9 Ruby.
