Cartridge Compliance/Arm Mass chart

The following is a quick reference for Soundsmith cartridges and tone arm mass matching;

The simple rule is that the LIGHTER the arm, the HIGHER the compliance must be.  How can you get around this? By using a heavier cartridge, and/or our EZ mount screws, you can effectively make the arm heavier.

* Cartridge Mass -  PLEASE NOTE - The ES suffix is the current design - earlier models (non ES) weighed less
