I have been listening to records with this exact stylus the past 10 years. I’m worried it breaks my records without me noticing.
There’s no way in judging your stylus with a picture like that. You should be able to hear if it still sounds good. If not, change it.
Ok two ideas. 1. Listen to a record you know very very well with headphones. Take the same record/headphones to a local record shop that has a turn table setup or a friend’s house and listen 2. Buy a new needle because eventually you are going to new a new one right? Try it out and if the old one isn’t that bad then you have a backup. Remember needles seem expensive 100-300 but how many records is that? Maybe less than 10 and it is the one thing that really determines how your collection sounds.
