Product Summary
The ARCAM A50 Signature is a high-performance integrated amplifier created to celebrate 50 years of ARCAM amplification. Designed in Cambridge and developed in collaboration with ARCAM co-founder John Dawson, it honours the brand’s long heritage while looking firmly towards modern music listening.
At the heart of the A50 Signature is ARCAM’s first dual-mono Class G integrated amplifier design. Each channel is built as a fully independent amplifier module, with its own transformer windings, power regulation, reservoir capacitors, Class G lifter stage and output-stage heatsink. This helps deliver excellent channel separation, low noise and powerful, controlled dynamics.
With 150 watts per channel into 8 ohms and 220 watts per channel into 4 ohms, the A50 Signature has the drive and authority needed for serious loudspeakers. Its Class G design combines the refinement associated with lower-power operation with the extra reserves required for demanding musical peaks, giving the amplifier a sound that is clean, confident and expressive.
The A50 Signature is also designed for the way people listen today. It includes a built-in ESS ES9039Q2M DAC, HDMI eARC for TV sound, USB-C for high-resolution digital audio, analogue inputs, and a built-in Class A moving magnet and moving coil phono stage for vinyl. Bluetooth 5.4 with Snapdragon Sound, aptX Lossless, LE Audio and Auracast support also allows high-quality wireless listening with compatible devices.
As the flagship integrated amplifier in ARCAM’s Radia range, the A50 Signature is ideal for customers who want a powerful, flexible and beautifully engineered amplifier that can sit at the centre of a serious music and entertainment system.
