Great cartridge! jw944ts. My first Porsche was a 1986 944 Turbo in Guards Red:)
The A95 has a compliance of 13 um/mN
Resonance frequency = 159 divided by the square root of ( total effective mass X Compliance)
You add together the effective mass of the arm with the weight of the cartridge and screws to give you the total effective mass.
You want the resonance frequency between 8 and 12 Hz. I suspect your arm may be a little on the light side but you can always add mass. You can figure out how much with this equation. The best way of determining what you actually have is by hooking an oscilloscope up to your phono stage and by using a test record with resonance band you can easily see the peak. Most of us just keep a careful eye on the cartridge watching for the tell tale shake and listening for the tone to warble.
Soundsmith makes a neat set of cartridge screw or various masses so you can adjust the effective mass of your arm.
