I have the JA Michell gyro se with a Moerch DP 6 arm.
Recently switched cartridges from a Benz Ruby Z to a Hana Umami Red.
My Ruby Z was 4 yrs old with 1500+ hrs but still sounded good.
The Hana is a huge upgrade, though maybe not a fair comparison.
Plenty of reviews on line, the Hana is an "overachiever "
