MM Cartridge


I have a new VPI Prime Scout table with the JMW 9 tonearm
I'm using. Sumiko Pearl cartridge and sounds amazing.
I want to upgrade to the  best MM. My preamp has a 3.1 mv, so I would like your opinion.
Audio Technica VM760SLC or Ortofon 2M Black, or other high output cartridge. I do not want a MC, want user replaceable stylus?

For new cartridges (in addition to what you have already mentioned), the upper end clearaudio MM's are also very good. If you're not afraid of purchasing used...
Grado Signature series
Empire 4000 DIII
Empire 2000 Z

If you have a month or so... Check out the HUGE MM thread Raul started here. There are a lot of old MM/MI carts that are really good.  
If you can still find one, the JICO stylus will make a shocking difference to your Pearl, and may be enough to keep you happy
Post the mass of your tonearm first, because recommendations here are blind, some cartridges are not compatible with your tonearm (if a compliance is too high or too low).
