Arcam A50 Signature Integrated Amplifier

Dual-Mono, Class G Integrated Amplifier

Created to celebrate 50 years of amplifier design, the Arcam A50 Signature is the company's finest integrated amplifier to date. Developed in Cambridge in collaboration with ARCAM co-founder John Dawson, it combines decades of engineering expertise with the latest analogue and digital technologies to deliver exceptional performance from every source.

At the heart of the A50 Signature is ARCAM's most advanced Class G amplifier design yet. It's also the first integrated amplifier from the company to feature a fully dual mono Class G architecture, with each channel having its own dedicated amplifier circuitry, power regulation and transformer windings. This highly sophisticated design improves channel separation, reduces noise and distortion, and creates a spacious, detailed and effortlessly controlled sound.

Delivering a powerful 150 Watts per channel into 8 Ohms, the A50 Signature has the authority to drive a wide range of loudspeakers with ease, while retaining the refinement and musicality for which ARCAM amplifiers are renowned.

Whether your music comes from a turntable, television, CD player or streaming source, the A50 Signature is designed to sit at the heart of a modern hi-fi system. A premium ESS ES9039Q2M DAC handles digital sources with exceptional precision, while HDMI eARC allows your TV to become part of your hi-fi system. USB-C, optical and coaxial digital inputs provide flexible connectivity for streamers, computers and disc players.

Vinyl enthusiasts are equally well catered for thanks to the built-in Class A moving magnet and moving coil phono stage, allowing a wide variety of turntables and cartridges to be connected directly without the need for an external phono pre-amplifier.

Wireless connectivity is equally impressive, with two-way Bluetooth featuring Snapdragon Sound and Auracast support for high-quality wireless music streaming and compatible wireless headphones or speakers. Traditional wired headphone listening is also supported for private listening sessions.

From its carefully engineered dual mono layout to its comprehensive connectivity, every aspect of the A50 Signature has been designed with one goal in mind: to deliver the most accomplished integrated amplifier ARCAM has ever produced.
