== Citation for virgin vs. recycled vinyl claims? ++ 

 The article states "Since most vinyl records contain up to 30% recycled vinyl, impurities can accumulate in the record and cause even a brand-new record to have audio artifacts such as clicks and pops". But I don't see a citation. It certainly sounds plausible, and I've had many people tell me that 'virgin vinyl' is better, but I have yet to find a substantiated claim as to why. It seems all opinion based at this time. Is there a reason recycled would have more impurities than virgin (as far as I know, recycled plastics are cleaned of impurities just as virgin plastics are)?
