Denon’s AVR X2800H and AVR S670H home theater receivers are currently available at reduced prices, giving buyers two different options depending on how many channels and surround sound features they need.
The AVR X2800H is the more capable model, offering a 7.2 channel configuration along with Dolby Atmos and DTS:X support. It is currently priced at $1,149.99.
The more affordable AVR S670H uses a 5.2 channel layout and is available for $519. Both receivers support 8K video passthrough, HDMI 2.1 gaming features, HDR formats, WiFi, Bluetooth and AirPlay 2.

AVR X2800H is the better fit for full surround sound setups
The AVR X2800H provides seven amplified channels, making it suitable for larger home theater systems.
It supports Dolby Atmos, DTS:X, Dolby Surround and DTS Neural:X. Dolby Atmos Height Virtualization and DTS Virtual:X are also included, giving you more options for creating a surround effect even when a full speaker layout is not possible.
Power output is rated at 95W per channel into 8 ohms with two channels driven. That increases to 125W per channel at 6 ohms under a different test condition.
The receiver has seven speaker terminals and two subwoofer outputs, allowing more flexible speaker arrangements than the smaller model.
It also supports two source, two zone audio, which can be useful if you want to send different audio to separate areas of the home.
S670H keeps many of the important video features
The AVR S670H costs significantly less but still supports many modern video standards.
It includes six HDMI inputs, with three capable of handling 8K signals. There is also support for 8K passthrough and 4K to 8K upscaling.
Gaming related features include variable refresh rate and Auto Low Latency Mode. Both receivers also support HDR10+, Dolby Vision, HLG and Dynamic HDR.
The biggest differences are on the audio side.
The S670H is limited to five amplified channels and does not support Dolby Atmos or DTS:X. It delivers 75W per channel into 8 ohms with two channels driven.
For a traditional 5.1 or 5.2 speaker setup, that may be enough, especially if immersive height channels are not a priority.
Both models include wireless streaming and room correction
Both receivers include HEOS, WiFi, Bluetooth and AirPlay 2.
They also work with voice assistant platforms including Amazon Alexa and Google Assistant.
Automatic speaker calibration is included on both models, though the X2800H uses the more advanced Audyssey MultEQ XT system. The S670H uses standard Audyssey MultEQ.
Each receiver also includes phono input support, making it possible to connect a compatible turntable without requiring a separate phono preamp.
High resolution audio playback through USB is supported at up to 24 bit and 192 kHz.
The X2800H provides four analog audio inputs, while the S670H has two. Both have optical and coaxial digital inputs.
The current pricing makes the choice fairly straightforward. The AVR X2800H is aimed at buyers who want Atmos, seven channel amplification and more room for future expansion. The S670H offers many of the same HDMI, HDR and streaming features at a much lower price for simpler 5.2 channel systems.
The offers are listed for the US market, and pricing may change depending on availability.
