The Goldring D12GX is the factory replacement stylus for the Goldring 1012 and 1012GX moving magnet cartridges. It sits within the upper tier of Goldring's 10xx series replacement styli, positioned above the D10 (for the 1006) and the D22GX (for the 1022GX), using the same Gyger II profile that distinguishes the 1012GX from entry-level models in the range.
Gyger II Diamond Stylus
The D12GX is fitted with a Gyger II nude diamond stylus — a fine-line elliptical type with a 6 µm small radius. The advanced diamond tip polishing delivers smooth, extended high frequencies with low distortion, while the fine contact radius improves tracking ability and reduces record wear compared to standard elliptical profiles. The equivalent tip mass is just 0.45 mg, keeping the moving mass low for accurate transient response.
Compatibility & Installation
The D12GX is a direct user-replaceable stylus assembly designed to clip into the Goldring 1012 and 1012GX cartridge bodies without tools. When the original stylus wears or sustains damage, replacing it with a new D12GX restores the cartridge to its factory performance specification — a cost-effective alternative to purchasing a complete new cartridge. The cartridge body itself uses Pocan, a glass-reinforced polyester chosen for its combination of low mass and high rigidity.
Performance Specification
With the D12GX stylus fitted, the 1012GX cartridge delivers a frequency response of 20 Hz – 20 kHz ±3 dB, channel separation better than 25 dB at 1 kHz, and an output of 6.5 mV ±1.5 dB at 1 kHz (5 cm/sec). Recommended tracking force is 1.5 – 2.0 g, with a nominal setting of 1.7 g. The cartridge presents a 47 kΩ load resistance with 150 – 200 pF recommended load capacitance.
