Sharing some thread relevant cartridge experiences-
Had an original ART9, loved it to death. huge value.
Ortofon Cadenza Blue was a significant upgrade in most, but not all areas. Bigger sound and dynamics but the ART9 was more colorful and refined.
Recently tried the ART9XA (ultra low output). Loved the sound but it really needs a SUT to shine dynamically.
Also tried a Zephyr MIMC star ES. Dynamics were very good but a letdown considering the low mass of the fixed coil deign. Not very refined or a big soundstage. The value comes with the rebuild cost but the sound is not competitive at its price as it had the least appealing sound of the bunch.
Bought a Lyra Delos and was underwhelmed at first but after ~ 120 hrs. holy toledo what a big dynamic sound! Smooth and refined with instant speed and dynamics, huge sound stage, detailed with no edge.
By far the best cartridge in my stable. I have tried to swap others back in but they do not last long.
Recommendation would be the Delos, then the Ortofon Cadenza Blue followed closely by the high value AudioTechnica ART9XI. .
