Our Review

The Denon AVC-S670H is a seriously capable home theatre amplifier that brings top-tier sound and visuals into your living room without breaking a sweat. With support for 8K video on three HDMI inputs and all the big-name HDR formats, your movies and games will look stunning. It backs that up with powerful, high-definition surround sound thanks to Dolby TrueHD and DTS-HD Master Audio, and even gives older content a new lease on life with clever upmixing tech. The 5-channel discrete amp pushes out up to 100W per channel, more than enough juice for a small to mid-sized setup. It’s also got HEOS® Built-in, so you can stream tunes via Spotify, Tidal, Apple Music and more, then beam them to Denon wireless speakers in other rooms - all controlled from your phone. Add in Wi-Fi, Bluetooth, AirPlay 2, and Denon’s user-friendly setup with Audyssey room calibration, and you’ve got a slick all-rounder at the heart of your home entertainment.
