Arcam Radia A50 Signature Integrated Amplifier
The Arcam Radia A50 Signature is a statement integrated amplifier created to celebrate 50 years of Arcam amplification. Designed and engineered in Cambridge, it sits at the top of the Radia range and introduces Arcam’s first dual-mono Class G integrated amplifier architecture.
Combining substantial power with exceptionally low distortion, a newly developed MM/MC phono stage, high-resolution digital inputs and advanced Bluetooth connectivity, the A50 Signature is designed for listeners who want genuine high-end performance from a single, beautifully engineered amplifier.
Arcam’s First Dual-Mono Class G Integrated Amplifier
At the heart of the A50 Signature is Arcam’s most advanced Class G implementation to date. Each channel operates as a largely self-contained amplifier module, with its own transformer winding, power regulation, reservoir capacitors, Class G lifter stage and output-stage heatsink. This dual-mono approach helps improve channel separation, reduce noise and provide the dynamic headroom required to control demanding loudspeakers with confidence.
The result is an amplifier designed to deliver the natural, fluid character associated with Arcam Class G, but with greater scale, authority and refinement.
150 Watts Per Channel
The A50 Signature delivers 150 watts per channel into 8 ohms, rising to 220 watts per channel into 4 ohms. This substantial output gives it the ability to drive a wide range of high-performance bookshelf and floorstanding speakers, while retaining excellent control at both low and high listening levels.
With harmonic distortion specified at just 0.002% at 80% power into 8 ohms, the A50 Signature combines muscle with exceptional precision.
Class A MM and MC Phono Stage
Vinyl playback is given particular attention with a completely new Class A moving magnet and moving coil phono stage. This allows the A50 Signature to work directly with a broad range of turntables and cartridges without requiring a separate phono preamplifier, making it equally suitable for established analogue systems and modern mixed-source hi-fi setups.
ESS ES9039Q2M DAC
Digital playback is handled by a high-performance ESS ES9039Q2M DAC, selected to complement the amplifier’s low-noise dual-mono architecture.
USB-C supports high-resolution digital audio up to 32-bit/384kHz, while the other digital inputs support sample rates up to 192kHz. This makes the A50 Signature an excellent partner for network streamers, computers, CD transports and other digital sources.
HDMI eARC for TV Sound
The inclusion of HDMI eARC allows the A50 Signature to become the audio centre of a premium two-channel television system.
Connect a compatible TV and enjoy significantly improved sound through your hi-fi speakers, with straightforward system integration and convenient everyday operation. For customers who want serious music performance without installing a separate AV amplifier, this makes the A50 Signature particularly versatile.
Advanced Bluetooth with Snapdragon Sound
The A50 Signature features Bluetooth 5.4 with support for: aptX, aptX HD, aptX Lossless, AAC, SBC, Snapdragon Sound, LE Audio and Auracast
It can operate as both a Bluetooth receiver and transmitter, allowing music to be streamed into the amplifier or sent wirelessly to compatible headphones.
Wired and Wireless Headphone Listening
A dedicated headphone output supports loads from 16 ohms to 2k ohms, providing plenty of flexibility for a wide range of headphones. Wireless headphone listening is also available via Bluetooth, giving users the choice between traditional wired listening and the convenience of compatible wireless headphones.
Premium Radia Design
Visually, the A50 Signature continues Arcam’s contemporary Radia styling, with a clean, purposeful appearance designed to sit comfortably within both modern and traditional hi-fi systems.
Internally, however, the Signature model moves well beyond the standard Radia integrated amplifiers, with its dual-mono power architecture, upgraded analogue stages and newly designed DAC, phono and volume-control sections.
Designed for Serious Two-Channel Systems
The A50 Signature is intended for listeners who want the authority and control of a powerful high-end amplifier without losing the refinement, timing and musical engagement for which Arcam has long been known.
Its combination of Class G amplification, advanced digital conversion, vinyl support and modern connectivity makes it equally suitable for traditional hi-fi systems and contemporary installations built around streaming, television and digital sources.
A New Reference for ARCAM
Created for Arcam’s 50th anniversary, the A50 Signature represents the most ambitious expression of the company’s integrated amplifier philosophy to date.
Its dual-mono Class G architecture, 150W output, advanced DAC and flexible analogue connectivity make it a compelling choice for anyone building a high-end two-channel system around demanding speakers, premium digital sources and vinyl playback.
