Stereophile - 2017 500 Recommended Components

The Model 312S precision pick-up arm is an extension of the popular Series 300 range designed with maximizing performance and ease of use in mind. It has a detachable magnesium headshell to provide the convenience of rapid cartridge interchange while maintaining a degree of rigidity normally only associated with arms of one piece design. The 12-inch magnesium construction takes advantage of the reduction in maximum tracking error/distortion afforded by the greater arm length when compared with 9-inch models.

Features

  • The 12in pressure die-cast magnesium construction takes advantage of the reduction in maximum tracking error/distortion afforded by the greater arm length when compared with 9in models.
  • Unique pressure die-cast magnesium shell detachable and interchangeable without disturbing cartridge or wiring.
  • Design of headshell clamping ensures a rigid junction with the 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. Axes at record mean level to minimise warp-wow.
  • Unique assembly gives high rigidity and allows bearings to be critically adjusted before the 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 calibrated to correspond 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 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).
  • Alignment protractor designed to provide HTA setting with greater accuracy.
  • Cartridge leads and internal wiring in Silver litz.
  • Balanced Silver-hybrid audio lead with gold plated phono plugs
