In that thread there are many folks who decide which turntable to play the LP on based on the condition of the LP. Poorer quality LPs are played on more affordable turntables and cartridges.All styli eventually wear out.
It's not so much that I'm worried that a worn record is going to wear out the stylus faster.
I'd rather use the less expensive cartridge if the record isn't going to sound the best and use the better cartridge on better quality vinyl. Yes, I'd like to make the better cartridge last longer.
Does that "compute"?
