Audiomirror...If you're question is regarding the "S" on the new Benz's, I understand that it pertains to the frame of the cartridge. The S class has a brass frame which reduces the resonances of the cartridge due to its more stable platform. The S series is therefore heavier than the original. I never A,B'd them, but I understand that the S series is slightly cleaner. I have an Ebony LP original that I'm very happy with. When the stylus becomes worn, I will take advantage of the Benz exchange program for an "S".
