Arcam AVR21 — Ex-Demonstration This Arcam AVR21 is our own Norwich showroom demonstration unit, now available at a reduced price. It is sold complete with all original packaging and accessories, in full working order exactly as supplied new by Arcam. The Arcam AVR21 is a 16-channel AV receiver built around the same Class AB amplification topology found in Arcam's dedicated stereo amplifiers — seven channels of high-power amplification driven by an overengineered toroidal transformer that delivers real-world power with a noise floor that sets a new standard for AV receivers at any price. The AVR21 is not a receiver that has been engineered down to a price; it is a receiver that has been engineered up to a performance level, and the difference is audible from the first moment. Native decoding of Dolby Atmos, DTS:X and Auro-3D across all 16 channels means the AVR21 resolves immersive audio formats with a completeness that lesser receivers cannot approach. Dual ESS 9026PRO audiophile DACs — each regulated by ESS reference voltage regulators — handle digital conversion at a level of precision that preserves low-level detail and dynamic integrity throughout the signal path. Dirac Live room correction is included as standard, transforming the AVR21's performance in real-world listening rooms and unlocking levels of imaging precision and bass control that acoustic treatment alone cannot achieve. Streaming is handled natively via Apple AirPlay 2, Google Chromecast, Bluetooth with aptX HD, Spotify Connect, Tidal Connect and UPnP through the MusicLife app. The AVR21 is also Roon Ready. Seven HDMI inputs and three HDMI outputs — including Zone 2 and eARC — are all HDMI 2.1 with HDCP 2.3, supporting 8K@60fps and 4K@120fps. HDR support covers Dolby Vision, HDR10+, HDR10 and HLG.
