Arcam Radia AVA25 AV Amplifier
The Arcam Radia AVA25 is a nine-channel AV amplifier engineered in Cambridge, UK — a product that carries nearly 50 years of Arcam's experience in sound design into a single chassis built for serious home cinema and music listening alike. It uses Class AB amplification developed in-house, and it is the amplifier in the Radia AV range for those who want the warmth and detail of Arcam's analogue heritage applied to multichannel film and music playback.
Wireless Connectivity
Bluetooth 5.4 is fitted, supporting A2DP, AVRCP, Snapdragon Sound, AAC, LE Audio, Auracast, and a full set of GATT profiles including VCP, MCP, BAP and CAP. Wi-Fi covers IEEE 802.11 a/b/g/n/ac across both 2.4GHz and 5GHz bands.

Who Is It For?
The AVA25 suits the home cinema listener who wants Arcam's build quality and amplification heritage in a nine-channel package, and who values the consistency of Class AB across all channels. It is not a budget compromise — at this level, the engineering behind the output stage is as considered as anything in the Radia range — but it is the natural starting point in the Radia AV amplifier line before stepping up to the Class G topology of the Arcam Radia AVA35.
Those considering an AV receiver rather than a pure amplifier should look at the Arcam AVR31 or the Arcam AVR11. For two-channel listening alongside, the Arcam SA35 Streaming Integrated Amplifier is worth pairing with it.
