I have LPs with hundreds of plays that sound brand new. Ohers begin to display clicks and pops much sooner, no matter how well they are cared for. The answer: it depends.
How long should vinyl last?
Say I found a prestine copy of Sgt. Pepper's Lonely Heart Club Band. It was brand new and never opened. If I play it on a state of the art turntable, how many years of play can I get out of it if I play it once a week and take excellent care of it? How long before the initial crispness disappears?
