Ortofon Anna or Transfuration Proteus?

I am now using SPU Gold cartridge with Ortofron 309 tonearm and Garrard 301 turntable, together with a Bob's Device SUT to Shindo Monbrison preamp.

I am considering upgrading the cartridge to either Ortofon Anna or Transfuration Proteus, looking for higher resolution and separation, more dynamic and air, and better tonal colour. (...am I asking to much?)

Much appreciated for your input.
