Technics S-shape magnesium tonearm (SL-1200G)

Tonearm

What it is

STUB ENTRY: factory-fitted on SL-1200G. Magnesium variant of the S-shape geometry — same effective mass and length as the aluminium version but improved damping.

Competition record

Assessed against 14 rivals across the sixty systems: it takes the slot in none of its 50 head-to-heads.

Where it gives ground

The dimension the engine names as the weakest link, counted across every head-to-head it lost.

  • mechanical hush ×33
  • speed stability ×14

Who it comes up against

Vertere Groove Runner X

17 lost · Anchored, Artisan, BBC Sound, Cavity-Native, Characterful, Intimate, PRaT, Reference, Romantic, Silent Path
