The AVR-S770H is an 8K AV receiver with built-in HEOS multiroom streaming from Denon, sitting above the AVR-S670H with genuine Dolby Atmos and DTS -X support and a seven-channel configuration. The AVR-S770H brings Denon's considered engineering to a more comprehensive home-theatre format.
Key specs that matter
Seven main channels plus two dedicated subwoofer channels are provided - more than the AVR-S670H's five channels. Dolby Atmos and DTS -X decoding are both supported, with a built-in MM phono input. Output power is 140W into 8 ohms - somewhat more than the AVR-S670H's 135W. At 434 x 339 x 151mm and 8.6kg, the AVR-S770H shares chassis dimensions with the AVR-S670H at somewhat lighter mass.
Sound and use context
Expect capable, accessible surround-sound reproduction reflecting the seven-channel configuration with full Dolby Atmos and DTS -X object-based decoding, consistent with Denon's broader accomplished home-theatre engineering standards.
Pairing
The seven-channel plus two-subwoofer configuration suits a capable domestic home-theatre setup, and the built-in phono input covers a turntable directly.
Alternatives
Denon's own AVR-S670H offers a more compact, five-channel alternative within the same broader receiver catalogue.
