I have thought the very same thing, especially after reading the life expectancy on the JICO. Have you ever heard of a stylus that is expected to last only 150 hours? It's a new one on me. I have a few things to send to VAS and they have my VPI bearing currently.
Was starting to think this might be the wrong forum to ask about an old Shure MM. We're all MC snobs here, aren't we? I do have both, a few of each.
