To help with Cartridge Break In and loosen up to assist with optimizing a Suspension, I have in the past been given an advisory on a method to save the stylus usage during the process.
This requires that the the stylus when mounted on the Tonearm is placed onto a non rotating LP.
I have a Device that produces a vibration and I set it in a Position such that a very mild vibration sensation is transferred and able to be detected through the LP. I then observe the Stylus to see if the part seems unaffected by the vibration being encountered. As long as the stylus is not showing any obvious movement to the eye, I continue with the level of vibration selected.
This will save the Diamonds User Life whilst gently transferring energy through the suspension, and assisting it to become pliant when in use.
I have done this on Two occasions, of which one was for approx' 4 Days on a New Cartridge and the other being a Half Day on a used but Long Term Stored Cartridge. I am not aware of any unwanted effect on a Cartridge by using this method.
