Music Hall Stealth Owners - What Cartridge Are You Using?

A few weeks back I purchased a Music Hall Stealth turntable and have been enjoying it as it and the Ortfon 2M Blue break-in. That said, I will have interest in trying a better cartridge at some point and have an interest in learning  from Stealth owners what cartridges they moved on to and their firsthand comparative take vs the 2M Blue.  Thanks in advance for any response.
