The Lifespan of an LP?

I have many LP's I bought from 1964 onwards, 57 years, still sound great.
If you pay attention to cleaning and if your tonearm and cartridge is set up good they should not wear.
I am not guessing about this, it is my experience. In fact as I upgrade they are sounding better than when I first bought.

i've heard examples of records that sounded trashed even played with a line contact, but on an ELP, with the tracking laser point carefully dialed in, it was often possible to find a spot with less wear than the rest of the groove, and the record's audible grade improved to VG or better. for those here rich enough to get an ELP, as finicky and impractical as they are, i have not heard any better reproduction of trashed records than on that miracle machine. just make sure the record is lab-grade clean before you put it on, or you and your tweeters will be sorry. 

What is ELP?

I have many albums from the mid fifties onwards still sound great and no warped edges. Some have been played weekly to monthly or very seldom. No difference.. Take care of them and they will outlast you. Mine surely will ! 😃

Shure answered all of this debate, definitively, hands down, with its record wear/stylus wear study in 1954.

Go read it. It has never been disproven. It’s only been proven true and it’s findings reinforced over the last 67 years.

Duh!!!
