cartridges i have used on my GR in order
Lyra Delos. Amazing in all areas.
Ortofon Cadenza Blue. good dynamics but lacks the soundstage, detail and refinement of the delos
Audiotechnica ART9XA. Would have been a winner if i had a SUT. The ART9XI is safe bet.
Soundsmith Zephyr MIMC Star. Overpriced and does not compete with the ART9. Big dissapointment.
