From the research and information I have been able to uncover over the years here is what I have found....with a properly set up, good quality analog system, and with clean vinyl (very important), you can expect approx. 1,000 plays prior to loosing the high end of the music. Accidents, poor tracking, and dirty records can shorten the effective life dramatically. I own, and still play on a regular basis, vinyl that exceeds 45 years in age!
