The Series 300 broadens the application of SME technology.

An adjustable and removable magnesium headshell provides a combination of high performance and convenience in the Model 309 tonearm. Get the workmanship and performance of SME- ABEC-1 bearings, LC/OFC internal wire and tonearm cable, and static tracking force - at a more affordable price.

The detachable magnesium headshell has a new style coupling, providing the convenience of rapid cartridge interchange without loss of rigidity.
Our designers can be justly proud of these models which offer a performance and manufacturing excellence unmatched by many more expensive models.

  • Unique pressure die-cast magnesium shell detachable and interchangeable without disturbing cartridge or wiring.
  • New design clamping arrangement ensures rigid junction with tone-arm.
  • Internal constrained layer damps minute residual vibrations making tone-arm acoustically inert.
  • Stainless steel cross shaft, ground and thread ground. Carried in massive yoke on 10mm precision ball races. Axis at record mean level to minimise warp-wow.
  • Unique assembly gives high rigidity and allows bearings to be critically adjusted before tone-arm is fitted.
  • Stainless steel vertical shaft, ground and thread ground, with integral 16mm diameter flange to couple shaft and yoke.
  • 23mm diameter steel pillar, heat treated, ground and honed, carries two 17mm precision ball races, widely spaced to resist tilt.
  • Anti-skate control operates through tension spring and filament. Dial corresponds with VTF and has positive OFF position.
  • Lowering/raising control gives smooth positive action. Height of lift can be adjusted.
  • Dual-lock base provides movement control with high rigidity.
  • Tungsten-alloy balance weight carried on damped two-point suspension. Extra-low inertia design assists warp riding.
  • Underslung weight housing corrects centre of gravity and provides non reflective tone-arm termination.
  • Swivelling, damped output socket minimises vibration transmission in sub-chassis use.
  • Reference lines on tone-arm facilitate VTA setting.
  • Fine adjustment of horizontal tracking angle (HTA).
  • New design alignment protractor sets HTA with great accuracy.
  • Cartridge leads and internal wiring LCOFC litz.
  • Balanced LCOFC audio lead with gold plated phono plugs.
