The 20/12 is a larger and more massive version of the famous SME Model 20/2.
It will accept nine, ten and twelve-inch arms but is especially directed at the exciting Model 312S. This offers a performance some 27% better than a nine-inch arm in respect of angular error distortion. The wand and headshell are pressure die-cast in magnesium and are 27g lighter than they would be in aluminium.
In the Model 20/12, superb instrument quality machining is allied with fundamental physics. The higher the mass and stiffness of a body the less it will flex and vibrate.
The SME Model 20/12A comes with the SME series 312s tonearm.
