ARCAM Radia Amplifiers Updated
22.09.2025 05:50 | ~2 minutes read
ARCAM has introduced the development of its Radia electronics line – three new integrated amplifiers ARCAM Radia A5+, A15+ and A25+ have been added. The devices use modern circuit solutions, an improved power management system to reduce interference and support the latest version of the Bluetooth wireless interface. Power supplies and printed circuit boards have also been upgraded.
All three amplifiers – ARCAM A5+, A15+ and A25+ – are equipped with Bluetooth version 5.4 with support for aptX Lossless and LE Audio, as well as Auracast technology for multi-user playback. ARCAM engineers paid special attention to noise control. To reduce the noise level, selective disabling of inactive modules (Bluetooth, HDMI, trigger inputs) is used, which ensures cleaner playback. The older models ARCAM A15+ and A25+ are equipped with an HDMI eARC port for convenient integration with modern TVs.
The ARCAM A25+ integrated amplifier has a new power transformer with separate windings for the DAC and digital stages, additional power stabilization for analog circuits, improved power supply filtering, a DAC on the ESS9018 chip from ESS Technology, and a USB-C input. The ARCAM A25+ delivers 2×100 W (class G).
The ARCAM A5+ integrated amplifier delivers 2×50 W (class AB) and is equipped with digital and analog inputs, an MM phono stage, and a Bluetooth adapter. The ARCAM A15+ model delivers 2×80 W. The A5+, A15+, and A25+ will go on sale in September 2025. The ARCAM A5+ retails for $1,199.95, the ARCAM A15+ is $1,499.95, and the larger ARCAM A25+ is available for $1,999.95.
