The S Class models of the Wood Body SL (low), SM (medium) and SH (high), all incorporate the Benz MicroRidge stylus coupled to improved generators using new coil windings and refined pole pieces/damper designs. Albert Lukaschek began researching increased performance and uniformity of his crosscoil designs while developing the Benz Ebony H, L and TR models. Experimenting with the length of the solid Boron cantilever revealed how the elasticity of this very stiff material contributed to compliance and trackability. Development of a grooved rear pole piece for countersinking the o-ring damper, first introduced on the Benz Ruby square plate cartridges, was then adapted to the cross coil designs, given their lower contact area and damping.
- The SL is .4mV at 3.54cm/sec with a coil impedance of 12 ohms, perfectly suited for MC phono stages with 60dB or higher gain.
- The SM is .8mV and 24 ohms, designed for less efficient systems and tube phono stages with gain between 45 – 58dB.
- The SH (2.5mV at 3.54cm/sec) is among the best high output moving coils ever made, ideal for MM type phono stages, low gain tube phono stages and AV systems.
