Stylus lifetime: with proper care we find that up to 1000 hours is possible without degradation of performance.
2M Series styli interchangeability:
The 2M Series’ engines, coils and magnets configurations are not identical: Red and Blue are identical, so are the Bronze and Black and so are the true mono variants 2M Mono and 2M 78. Likewise, 2M series styli are interchangeable within the below combinations:
- 2M Red, 2M Blue and 2M Silver
- 2M Bronze and 2M Black
- 2M Mono and 2M 78
