Recommend an MC cartridge
I have a Pure Fidelity Harmony TT with an Audio Origami PU7 tonearm and Stratos cart (modified Gold Note Donatello Gold) and have ordered a Whest Titan Pro phono stage. I'm looking for a suitable cartridge to replace the Stratos. I prefer something from My Sonic Lab, Ortofon or Hana.
Any suggestions?
