felicitous cartridge for the Masseto preamp ?

I'll be replacing my AudioQuest 7000 soon and would like to optimize the Shindo phono stage with a compatible MC cartridge. Any suggestions ?
Dynavector, Ortofon Royal N SPU standard type mount both work well direct in to the MC inputs on Shindo preamps. EMT's or Denon 103's both should be used w/ an A23 SUT.
thanks for your very specific recommendations. Now I can do some research and price comparisons.
