ARCAM A25 Plus
The ARCAM A25+ is a Radia integrated amplifier combining Class G amplification with analogue and digital source connections. Its rated output of 100 watts per channel into 8 ohms provides a clear step within the range, while the revised power supply is part of the Plus generation’s engineering updates.
Bluetooth 5.4 with Snapdragon Sound and Auracast expands wireless playback and headphone options. A moving-magnet phono input connects a compatible turntable directly, and a wired headphone output provides another listening route. The amplifier can also work with a matching Radia streamer as a separate-component system.
Fifth-generation Class G amplification, a new DAC, HDMI eARC/ARC and USB-C distinguish the A25+ from the smaller models. These connections accommodate vinyl, television and computer-based sources in the same system.
