A photo of the Replicant 100 was next to this updated claimWe have recently observed a number of discussions about stylus life time on HiFi forums. We have therefore decided to bring clearance in this matter and come with Ortofon official response:With proper care we find that up to 1000 hours is possible without degradation of performance. The stylus does begin to exhibit changes after 1.000 hours, but the stylus life as a whole is expected to top 2.000 hours.Proper care comprises the following:1. Cleaning of record by means of carbon fibre brush before and after every use. Cleaning of record by using record cleaning machine once in a while. 2. Cleaning of stylus by means of a fine antistatic brush. Please remember to remove dust from the diamond tip before and after playback of each record.3. Proper adjustment of antiskating, azimuth and tracking force
