the only way to tell is to look at the stylus under a microscope - wear that may be damaging your LPs could easily be inaudible.
Stylus wear question...
On more than one occasion, I've fallen asleep late at night listening to an LP and woke to the sound of the stylus tracking the inner lead out groove of the LP...perhaps for several hours. Does the time the stylus spends here cause greater wear than time spent on the music tracks? Thanks in advance. I did search posts under "stylus wear" - didn't find anything pertinent. (by the way, things still sound great...no audible evidence of any damage).
