Just put the VPI tool on and check the stylus against the grid. If it lines up you are good to go. For azimuth I just eyeball it and adjust accordingly.
I have the dual pivot so that helps.
Rechecking Cartridge Alignment
Had my Ortofon Cadenza Bronze installed 3 years ago and it has approximately 800 hours of playing time. Run it on a VPI Prime.
Question: When does it make sense, if at all, to have the alignment rechecked professionally? I am not hearing anything problematic, but don't know what I don't know.
