The full model number had me missing the issue, that this is a nice arm/arm tube with changeable but for sure very hard to find and pricey L and M versions of the arm tube for lower compliance cartridges. Since some of your cartridges do want to see an 8 gram effective mass, that arm will work with them for the lower compliance cartridges you would need the higher mass arm tubes, the M for medium compliance and the L for low compliance. The specs on the Japanese audio-database list the expected compliance for the different arms, at 100 Hz the Japanese standard.
