What is it the wears out on a cartridge?


The answer may be obvious, but it is actually the stylus or the suspension that wears out?

The next logical question is...What can be done to extend the life of a cartridge? Cleaning the stylus? How does temperature, humidity, and light affect the life of a cartridge? Anything else?

This is what I know. Your diamond lasts due to use. Your cantilever lasts due to time. Keep your records pristine clean. Clean your stylus every listening session. Also Last stylus treatment could be used, however some manufacturers advise against it on the grounds some of the treatment could damage the glue or some other adhesion in the cantilever. Tracking weight is crucial. Too much and the diamond will wear sooner or too little and the stylus will bump up and down potentially causing even more wear. At least on your records. The suspension does have a expiration date but it is not stamped on your box. The sound will change over time. One thing I would like to know. Do some suspensions on some brands last more than others???

Jan Allaerts uses 120 old rubber for the suspension on his cartridges to avoid aging of the suspension.
I've heard that local climate impacts the rubber O-ring at the base of the cantilever - hot and dry causing it to become brittle more quickly.
The diamond tip will probably last for decades and enormous hours but cantilever and suspension will loose flexibility hence substantially degrading performance
I have read that whatever surrounds cantilivers will dry out and deteriorate with time and the cantiliver can actually fall out.
