Quick answer

The Denon AVR-S670H is a 5.2-channel networked AV receiver rated by Denon at 75 W per channel (8 Ω, 20 Hz–20 kHz, 0.08% THD, two channels driven). It powers a conventional 5.1 system with up to two subwoofers. Denon lists it without Dolby Atmos or DTS:X, so it suits TV rooms that want streaming and room correction without height speakers.
