I've been reading up a bit on cartridge compliance and came across Vinyl Engines cartridge resonance calculator. It seems like a useful tool but I've confused myself a bit with it.
When it asks for the effective mass of your tonearm I am assuming that does not include the weight of the cartridge. I am also assuming that the weight of the headshell is included in the effective mass of the tonearm. When reading the table you look at the weight of your cartridge(plus screws)against the cartridge compliance to get the result. Is this correct?
