SME engineers worked for almost four years to design and build a tonearm that would make no detectable sound contribution of it's own, and came up with a product that has become widely accepted by technical experts and users as one of the worlds truly great audio products.
The details of how the engineers achieved such finesse can be widely read elsewhere around the web, however we simply couldn't mention the Series V without touching on it's performance capabilities.
In short, to achieve the optimum transfer from vinyl to your ears, the tonearm needs to be as stiff as the laws of physics will allow; and SME realised that satisfactory results could not be achieved with conventional fabricated constriction.
Instead of being made from multiple parts, the Series-V Tonearm is a one-piece die-casting in magnesium alloy comprising the shell, tube and balance weight cantilever. This construction is 36% lighter and only 25% less stiff than commonly used aluminium, yet a magnesium arm of the same mass could be as much as 25% stiffer. Magnesium also has a high self damping factor to damp the tube's high frequency resonance.
The internals were subject to the same level of scrutiny, resulting in internal wiring of specially developed silver litz, with each conductor having five insulated strands; whilst termination is done through high quality linear crystal oxygen-free copper audio lead selected for it's electrical and mechanical characteristics.
Finished in satin black enamel, with accents of black chrome and details in bright chrome and polished stainless steel.
Structurally, aesthetically and materially speaking, tonearms don't come much more advanced than the Series V-GPD
- Unique one-piece pressure die-cast tonearm utilising the advantages of magnesium.
- Internal constrained layer damps minute residual vibration leaving the tone-arm acoustically inert.
- Fine machined cartridge platform, enamel free to avoid interface resonance.
- A Stainless steel cross shaft, ground and thread ground.
- Dynamic balance graduated VTF control applies 0-3g x 0.125g ( resonance controlled spring).
- Unique assembly offers high rigidity and allows bearings to be critically adjusted before fitting.
- Stainless steel vertical shaft, ground and thread ground, integral 16mm diameter flange.
- 23mm diameter steel pillar, heat treated, ground and honed, carries two 17mm ABEC 7 ball races.
- Anti-skate control (tension spring and filament). Dial corresponds with VTF / positive OFF position.
- Lowering/raising control gives smooth positive action. Height of lift can be adjusted.
- Subsonic lateral mode fluid damper can be instantly adjusted or cancelled.
- Dual-lock base provides movement control with high rigidity.
- Tungsten-alloy balance weight. 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.
- Fine adjustment of arm height (VTA).
- Reference lines on tone-arm facilitate VTA setting.
- Fine adjustment of horizontal tracking angle (HTA).
- New design alignment protractor sets HTA with greater accuracy.
- Advanced jig/template system guarantees correct positioning.
