Mescabo, did you bother to read the referenced thread? If you did, you would have all of the answers that you need. 76doublebass, if "WHAT HE SAYS IS THE GOSPEL TRUTH", then why did you ask "What is the coorect (SIC) answer?" Is it that you need validation? If so, you won't be getting it here. Incidentally, no where do I read that John Chapis - who I have spoken to, having owned three of the Signature line, though not discussing sylus life with him - said that a cartridge would last 5000 hours. If you are quoting him directly, after dismissively offering you two minutes of his time, he threw out a question, "How does 5000 hours sound to you?" A question is not an answer. He does answer though with, "...a very long time." Sorry, two minutes does not constitute a serious discussion on the subject nor does your description of the conversation indicate that 5000 hours is the expected life of the cartridge.
