Tomorrow, a replacement stylus for my Ortofon Blue arrives. I guesstimate I have 600+ hours on the original. It still sounds very good. They'll supposedly go 800-1000 hours. When the new one arrives, do you think a good idea might be to play a track and listen closely, then immediately change to the new one and play the same track again. If I cannot detect any difference, put the original back in for another 100 or so hours? And then do that again until I get closer to 1000 hours? Or would that be too much wear and tear on the records? Is it only wear and tear if you can audibly hear that? I am kind of frugal that way I guess. I get the last drop from a tube of toothpaste, even though you can buy a tube for a couple bucks. Not sure if that's frugality. A guy on the radio (Joe Soucheray, if you are familiar) calls that "a last-dropper", which apparently is what I am.
