Arcam Radia AVA25

Audio Video Amplifier

Step into a world where every note and every scene is delivered with uncompromising precision and emotional depth. The Arcam Radia AVA25 isn’t just an amplifier—it’s the culmination of nearly 50 years of ARCAM’s mastery in sound design, created for those who demand nothing less than excellence.

Expertly engineered in Cambridge, UK, the AVA25 builds on our heritage with advanced Class AB amplification, developed in-house to deliver a richer, more musical performance. This is how we achieve sound that feels alive—rich, detailed, and effortlessly immersive.

With nine channels of powerful amplification, the AVA25 effortlessly drives immersive setups like 7.1.2 or 5.1.4, and offers expansion to 16 total channels with additional subwoofers, height, or surround speakers. Dolby Atmos, DTS:X, IMAX Enhanced and AURO-3D transport you with a cinematic experience, while Dirac Live room correction ensures flawless detail tailored to your space.

At ARCAM, sound quality isn’t just a promise—it’s our obsession. The AVA25 is the result of rigorous testing and listening sessions to award it the ARCAM name.
