How Long do LP's last

I have LP's that are more than 30 years old that I listen to, and they still sound great. The secret (IMO) is keeping the LP's clean and using a cartridge that requires moderate tracking force (I try to avoid going above 1.5 grams). But whatever cartridge you use, be sure to set the tracking force so the stylus does not mistrack -- that will ruin an LP in short order.

I have also treated most of my LP's with LAST, and have been very pleased with the long-term results. I don't know that there is a magic number for how many times an LP can be played before audible signs of deterioration occur, but based on my experience, I think several hundred times is a reasonable guess (again, assuming the points in the first paragraph are heeded).

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!

Interesting thought...how long will digital formats last?

G_m_c, digital...two weeks, until the next NEW format appears :-)
