Just installed a new Nagaoka mp110 cartridge the other day (the one in my picture), and I was wondering about this. I heard of some people using a little counter each time they play a side of vinyl, but I dunno how to manage singles, as 1 count per single is kinda inaccurate. is there a better way of doing this? I was thinking of creating an excel spreadsheet or something, but I feel like that might be too much work. Also on a somewhat related note, my cartridge manual said the stylus needs to be replaced every 250-300 hours. Seems a little much and I figure that must just be marketing? At that rate i'd need 2 styli per year, and that seems crazy. Excited to see how the naga sounds after break-in.
