Advanced Class AB Amplification

At the heart of the AVA25 lies ARCAM's advanced Class AB amplification technology—a topology refined through decades of British audio engineering. Class AB amplification combines the linearity of Class A operation with the efficiency of Class B, delivering sound that feels alive—rich, detailed, and effortlessly immersive. This is how ARCAM achieves performance that resonates emotionally whilst maintaining the technical precision audiophiles demand.

With nine channels delivering 100W into 8Ω (all channels driven) or 120W into 4Ω, the AVA25 provides substantial reserves for dynamic cinema soundtracks and delicate musical passages alike. When driving two channels, output increases to 125W into 8Ω or 200W into 4Ω, ensuring headroom for even demanding loudspeaker systems. Harmonic distortion measures just 0.005% at 80% power into 8Ω at 1kHz—testament to ARCAM's obsession with audio purity.

Immersive Audio Processing Excellence

The AVA25 effortlessly drives immersive setups like 7.1.2 or 5.1.4, and offers flexibility for expansion with additional subwoofers, height, or surround speakers. Dolby Atmos, DTS:X, IMAX Enhanced, and Auro-3D transport you with a cinematic experience that places you at the centre of the action. Virtual height processing through Dolby Atmos Height Virtualisation and DTS Virtual:X creates enhanced immersion even without dedicated ceiling speakers, whilst Dolby Surround and DTS Neural:X upmixing breathe new dimensionality into legacy content.

Dirac Live room correction ensures flawless detail tailored to your space, analysing your room's acoustic characteristics and optimising the AVA25's output to compensate for reflections, standing waves, and frequency irregularities. The result is performance that sounds as the artist intended, regardless of your room's dimensions or construction.

The frequency response extends from 20Hz to 20kHz with exceptional accuracy of ±0.05dB, whilst the signal-to-noise ratio of 100dB (A-weighted) guarantees a silent background from which even the subtlest details emerge. Maximum channel processing reaches 16 channels with full reassignability (subwoofers routable to channels 4 and 11-16), providing configuration flexibility for complex installations.

Cutting-Edge HDMI and Video Integration

The AVA25 is comprehensively equipped for today's 8K displays and tomorrow's requirements. Seven HDMI 2.1a inputs and dual outputs (plus an additional output for Zone 2) support resolution up to 8K/60Hz or 4K/120Hz. Advanced gaming features include Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) for responsive performance, whilst support for HDR, HDR10, HDR10+ Gaming, Dolby Vision, and HLG ensures stunning picture quality from any compatible source.

Enhanced Audio Return Channel (eARC) on Zone 1 Output 1 provides seamless integration with smart televisions, allowing high-resolution audio formats including Dolby TrueHD and DTS HD Master Audio to pass from your television's streaming apps directly to the AVA25. On-screen display facilitates straightforward setup and source selection, whilst CEC control integration creates a unified entertainment system.

Comprehensive Digital and Analogue Connectivity

Beyond HDMI, the AVA25 offers extensive connectivity for all sources. Two coaxial digital inputs support sample rates up to 192kHz at 24-bit resolution, whilst dual optical inputs handle signals up to 96kHz. Three pairs of analogue RCA inputs provide connectivity for turntables (via external phono stage), tape decks, or other line-level sources. All inputs maintain ARCAM's exacting standards: frequency response of 20Hz–20kHz ±0.2dB and signal-to-noise ratio of 100dB.

Sixteen RCA preamplifier outputs (2V RMS peak per channel) allow connection to external power amplifiers for expanded system configurations, with THD+N measuring –100dB across the 20Hz–20kHz bandwidth. This flexibility ensures the AVA25 can anchor both compact nine-channel systems and expansive multi-amplifier installations for dedicated cinema rooms.

Seamless Streaming and Network Playback

Modern connectivity meets traditional hi-fi excellence. The AVA25 works seamlessly with the new ARCAM Radia app for setup, control, internet radio, and podcasts. Streaming services integrate directly through Spotify Connect, Tidal Connect, and Qobuz Connect, whilst Apple AirPlay and Google Cast provide additional wireless streaming options. Roon Ready certification ensures bit-perfect playback from Roon-managed music libraries with complete metadata integration.

The amplifier supports comprehensive high-resolution file formats including FLAC, WAV, MQA, ALAC, AIFF, and DSD up to DSD128, with sample rates reaching 192kHz and 24-bit depth. Gapless playback ensures seamless transitions between tracks in albums and live recordings, whilst the streaming pathway maintains a frequency response of 20Hz–20kHz ±0.05dB—matching the performance of direct digital inputs.

Bluetooth 5.4 with Snapdragon Sound and Auracast ensures high-quality wireless audio transmission, supporting AAC, LE Audio, and multiple connection profiles for flexible wireless connectivity from smartphones, tablets, and computers.

Intuitive Control and Visual Feedback

Setup and streaming are effortless. The vibrant 6.5-inch high-resolution colour display presents status information and metadata with exceptional clarity, clearly visible from the comfort of your main listening position. Album artwork, track information, and system status appear with vivid detail, creating an engaging visual complement to the sonic experience.

The Bluetooth remote control allows continuous operation even when the amplifier is out of sight, whilst the ARCAM Radia app provides comprehensive setup and control from your mobile device. Intuitive on-screen menus guide you through system configuration, making professional-level room correction and speaker setup accessible to any enthusiast. The interface balances sophistication with usability, ensuring that accessing the AVA25's extensive capabilities never becomes a barrier to enjoyment.

Cambridge Engineering Heritage

At ARCAM, sound quality isn't just a promise—it's an obsession. The AVA25 represents the result of rigorous testing and critical listening sessions, more than earning the ARCAM name. Manufactured by Harman International in Cambridge, UK, the AVA25 benefits from the same engineering standards and attention to detail that have made ARCAM a benchmark in high-fidelity audio reproduction for nearly five decades.
