Sugden Masterclass LA-4 Class A Line Preamplifier
type: Product
description: Sugden Masterclass LA-4 – Class A Line Preamplifier The Sugden Masterclass LA-4 is a high-quality active line preamplifier designed for refined, fully analogue stereo systems. Combining a sophisticated Class A output stage with relay-controlled input and output switching, it provides precise system control while preserving the tonal character, dynamic expression and natural flow of the source material. Overview The LA-4 has been developed as the natural control centre for Sugden Masterclass and Sapphire power amplifiers, including the SPA-4 and MPA-4. Its high-gain architecture provides confident control over a connected power amplifier, while carefully selected transistors and capacitors support clean signal preservation throughout the circuit. Each gain stage is powered by a current-shunt differential power supply. This approach is designed to support rapid transient response and maintain composure during demanding musical passages. Gold-plated circuit boards and relay switching further reflect Sugden’s focus on signal integrity and long-term reliability. Key Benefits Natural system control: the active Class A output stage is designed to preserve tonal balance and low-level detail. Flexible analogue connectivity: line-level, tape, balanced and bypass inputs accommodate a wide range of source and system configurations. Balanced integration: balanced input and output connections suit premium pre/power systems. Convenient operation: motorised remote volume control allows precise adjustment from the listening position. Handcrafted construction: Masterclass components are assembled in Sugden’s Yorkshire factory.
