I was wondering how long Shure recommends the lifespan of the M44G stylus.. other cartridge companies have estimations in hours and I was wondering if I could get an approximation.
I have been using my M44Gs for 7 months and they still work very well but I was told that replacing the stylus is a good idea to do before loss in sound quality is heard, as to not cause further record wear.
Typical diamond stylus life is 500 to 1,000 hours of playing time. The wear depends upon many factors including the tracking force, the anti-skate setting, the cleanliness of the record groove, etc. Using a specially designed microscope is the only scientific way to determine stylus wear.
In your case, seven months is about 210 days. If you played records for 3 hours every day, the playing time would be 630 hours. In this case, a new stylus would be a good idea just to be safe.
