  • The 12in construction with thin walled stainless steel tone-arm takes advantage of the reduction in maximum tracking error/distortion afforded by the greater arm length when compared with 9in models.
  • S2-R Aluminum shell detachable and interchangeable without disturbing cartridge or wiring.
  • Double draw-in pin bayonet fitting design ensures a rigid junction with the tone-arm.
  • Unique headshell to tone-arm coupling readily allows cartridge azimuth adjustment.
  • Internal constrained layer damps minute residual vibrations making tone-arm acoustically inert.
  • Stainless steel cross shaft, ground and thread ground. Carried in a substantial yoke on 10mm precision ball races.
  • 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 Anti-Skate weight and filament, adjustable up to 5g VTF.
  • Lowering/raising control gives smooth positive action. Height of lift can be adjusted.
  • Thumbwheel (Vertical tracking angle VTA) height adjustment.
  • Bedplate affords +/- 12.0mm movement to facilitate (Horizontal tracking angle HTA) adjustment.
  • Base slides on bedplate for horizontal tracking adjustment with double null-point protractor.
  • Tungsten-alloy balance weight inserts allow maximum centre of gravity shift to balance a greater range of cartridges up to 38g in S2-R headshell and direct plug-in heads up to 46g.
  • Precise vertical tracking force up to 5g applied in 0,5g increments via rider weight and graduated wayrod.
  • Alignment protractor designed to provide HTA settings with the greatest accuracy.
  • Internal wiring in silver litz.
  • Balanced Hybrid Cable 1.2M audio lead with gold plated phono plugs.
