If you system sounds great, why bother.
What you could do however is to listen to a record which you use a lot. Check the higher frequencies for anomalities and the bottom end. If both seem ok, the sound does not seem frayed you are still all right. Also, if you use an LP which is exceptionallly quiet regarding background noise and it does get more noisy, a faulty stylus is plowing up the grooves. If however the Lp is still quiet, you are fine and can stop fretting.. for now.
