The 2M series styli are interchangeable within the following combinations: 1) 2M Red, 2M Blue, and 2M Silver, 2) 2M Bronze, 2M Black, and 2M Black LVB 250, 3) 2M Mono and 2M 78.

Special for 2M Red, 2M Blue, and 2M Silver phono cartridges: The 2M Silver will be an upgrade compared to 2M Red due to a special suspension and silver-plated copper wire material. The 2M Blue is an upgrade compared to both 2M Red and 2M Silver thanks to Nude Elliptical diamond which retrieves information from the groove with a higher accuracy.
