Birdfan, 16 gms seems a little heavy for that arm but I would certainly stay away from cartridges with a compliance over 20 u/mN. If it is indeed 16 gm then you had better stick with the Clearaudio cartridges which are down around 15 u/mN. Most MM cartridges are over 20 u/m. Soundsmith has low compliance cartridges but they are all low output. I assume since you were using a high output moving coil cartridge that you do not have a high gain phono section.
