SG 1.1

About the SG 1.1

The Spiral Groove SG 1.1 is a precision-engineered turntable designed to deliver unparalleled vinyl playback with extremely low noise and vibration. It features a heavy, dense body constructed from an aluminum and Delrin sandwich that isolates and dissipates vibrations. The platter is belt-driven at the bearing contact plane with a 14-inch aluminum or stainless steel drive ring to ensure exceptional speed stability. The platter incorporates layers of phenolic, vinyl, and graphite to reduce stylus-induced vibrations ('stylus talk'). A magnetic weight reduction system reduces effective platter weight on the sapphire thrust bearing, enhancing stability and longevity. The motor is a low-voltage, high-torque AC synchronous type powered by an outboard pure sine wave generator with phase correction and frequency adjustment, supporting 33 and 45 rpm speeds. The turntable includes height-adjustable feet made of graphite, aluminum, and elastomer. It is often paired with Spiral Groove's Centroid unipivot tonearm, which uses a balanced force design for near-perfect tracking and minimal inertia. The SG 1.1 is noted for its quiet background, precise speed control, and ability to reveal rich musical detail with depth and specificity. It comes with a 10-year mechanical and 3-year electrical guarantee.
