Some real black gold here: 45rpm live double album. Sounds stellar. Found at a record store that was (unfortunately) going out of business.

How can I determine when it’s time to replace my cartridge? I assume any degradation will be very gradual so what’s a good way to tell?

Edit: I should’ve said “stylus”. What in particular are the signs for stylus wear. Some comments said “inner groove distortion” - how does it sound. Are there any reference recordings or recommended recordings/tracks which reveal this?
