The Series 300 tonearms broadens the application of SME technology. A unique one-piece magnesium tonearm is used for the Model 309. The detachable magnesium headshell has a new style coupling, providing the convenience of rapid cartridge interchange without loss of rigidity. The Model 309 offers 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.

This beauty has graced my system for nine years, since SME started making it in magnesium. The removable headshell makes cartridge mounting and setup a delight, to include azimuth adjustment. About 15 different cartridges have been mounted, and they have all worked optimally and without a sign of dreaded sibilance. Cartridges from low to high output, and low to high compliance have all worked beautifully. This is a wonderful cartridge platform I would not be without, regardless of its upscale brothers. It is delightful and versatile.
