ARCAM A5+, A15+ AND A25+ JOIN RADIA SERIES WITH ENHANCED FEATURES
Three new ARCAM Radia+ integrated Amplifiers have joined the ARCAM Radia Series: the A5+, A15+, and A25+.
The new models build on the original ARCAM Radia amplifiers, adding refined circuitry, next-generation Bluetooth, and updated design details.
ARCAM RADIA+ INTEGRATED AMPLIFIERS
Each of the new ARCAM A5+, A15+, and A25+ models features upgraded internal components and power management to reduce interference and improve overall performance. Enhancements include transformer upgrades, refined power supplies, and reduced PCB noise.





NEXT-GENERATION BLUETOOTH
The ARCAM A5+, A15+, and A25+ all include Bluetooth 5.4 with Snapdragon Sound (AptX Lossless), Auracast for one-to-many playback, and LE Audio. These additions expand wireless streaming options and support higher-quality transmission.
FOCUS ON NOISE REDUCTION
ARCAM engineers have prioritised noise control across the A5+, A15+, and A25+. Selective power-down of unused modules, such as Bluetooth, HDMI, and trigger inputs,helps reduce the noise floor for cleaner playback.
ARCAM A15+ AND A25+ ADD HDMI EARC
The ARCAM A15+ and A25+ now feature HDMI eARC, enabling easy TV system integration. The flagship A25+ also gains an OLED display behind a glass front panel designed to match the ST25 streamer.
ARCAM A25+ RECEIVES MOST SIGNIFICANT UPDATES
Of the three, the ARCAM A25+ sees the most substantial engineering revisions. These include a new transformer with dedicated windings for DAC and digital stages, additional regulation in analogue power supplies, and improved mains filtering. It also adds an ESS9018 DAC for SPDIF inputs and a USB-C input.
ARCAM A25+ SPECIFICATIONS
As the flagship, the ARCAM A25+ delivers 2x100W of Class G power. It features HDMI eARC, SPDIF DAC, USB-C, and a glass-panel OLED display.
ARCAM A5+ SPECIFICATIONS
The ARCAM A5+ is a 2x50W Class AB amplifier. It includes digital and analogue inputs, a tuned MM phono stage, and the latest Bluetooth platform.
ARCAM A15+ SPECIFICATIONS
The ARCAM A15+ offers 2x80W Class AB power, HDMI eARC connectivity, and the same Bluetooth upgrades as the A5+.
