ARCAM Radia A50 Signature Dual Mono Integrated Amplifier with MM Phono and DAC
The ARCAM A50 Signature is a high-performance integrated amplifier created to celebrate 50 years of ARCAM amplification expertise. Designed, in conjunction with John Dawson, one of ARCAM's founding engineers and it carries his signature. It combines modern connectivity with advanced analogue and digital engineering.
Built around ARCAM’s most advanced Class G implementation to date, the A50 Signature is the brand’s first dual-mono Class G integrated amplifier. Each channel is a fully self-contained module, featuring independent transformer windings, dedicated power regulation, reservoir capacitors, Class G lifter stage, and output-stage heatsink. This architecture delivers exceptional channel separation, low noise, and high dynamic capability.
The amplifier supports a wide range of music sources, including digital streaming components, smartphones, TVs via HDMI eARC, CD players, and turntables. The DAC, phono stage, and volume control circuits are all new designs to complement the dual-mono amplifier and maintain signal integrity throughout.
The result is the best-sounding integrated amplifier ARCAM has ever produced, delivering consistent performance across digital and analogue sources alike.
