Soundsmith Strain Gauge SG-200 Phono Cartridge System

Unlike traditional magnetic cartridges that rely on electromagnetic induction, the Soundsmith Strain Gauge system measures the physical displacement of the stylus directly. This design allows for a significantly wider frequency response, reaching up to 70kHz, and eliminates the need for standard phono equalization stages.

Yes, the dedicated preamplifier and power supply are essential components of the SG-200 system. Because strain gauge technology operates differently than conventional cartridges, it requires this specific interface to power the cartridge and convert its signal for your audio system.

The system is designed with interchangeable styli, allowing you to choose between six different options to suit your listening preferences. You can easily swap them yourself, and the unit comes standard with the SGS-5 nude line contact, with the upgraded SGS-6 contour-optimized stylus also available.

The recommended vertical tracking force for this cartridge is between 1.7 and 1.9 grams. Its compliance is rated as low-to-medium, ranging from 10–16µm/mN depending on the tracking force applied.

The ruby cantilever is chosen for its exceptional rigidity and low mass, which helps minimize unwanted resonances. By reducing the effective tip mass to as low as 0.30mg, it ensures more accurate tracking and improved high-frequency detail retrieval.

The dedicated preamplifier and power supply unit measures 6 inches wide, 3 inches high, and 8 inches deep. It is a compact component, but you should ensure there is adequate ventilation around it despite its modest footprint.
