The Arcam AVR850 is a premium seven-channel A/V receiver designed to deliver outstanding audio fidelity. Priced at $6,000, it stands out due to its Class G amplification topology, which allows it to provide 120 watts per channel when driving two channels into 8-ohm loads, and 100 watts per channel for all seven channels driven. This design results in increased efficiency by utilizing lower voltage rails for normal operation while having high voltage sources available for transient demands. The AVR850 supports Dolby Atmos and DTS:X decoding, enabling immersive sound experiences for movies and music alike. One of its key features is the Dirac Live room correction system, which employs advanced algorithms for speaker setup and acoustic equalization, offering superior performance compared to other auto-calibration systems. The receiver is equipped with seven HDMI inputs and three outputs, supporting 4K HDR video formats, while also allowing for flexibility in speaker configuration, such as 7.1.4 or 5.1.2 setups. The build quality, including gold-plated binding posts and an elegant design, aligns with high-end audio aesthetics. Despite its premium pricing, the AVR850 is appreciated for its sonic performance, featuring an audiophile-grade Cirrus CS42528 DAC that handles 24-bit/192kHz audio. Overall, the AVR850 combines high-quality sound with simpler user ergonomics, complemented by a user-friendly remote control and a comprehensive manual.
