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: 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 the Nude Elliptical diamond which retrieves information from the groove with a higher accuracy.
