Cartridge Upgrade for Rega P-25 Table

I am currently using a Benz-Micro Mc 20 E 2 cartridge.

The rest of my system is
Harbeth Compact 7 ES2 or Proac Response 2
Quad 99/909 or Aronov 960i
Fosgate Phono Preamp

No price range, but I do not want to upgrade the TT right now.

I listen mostly to folk music and jazz with some occasional classic rock thrown in the mix.

I would appreciate input and suggestions on this. Thanks.
