Denon has added two richly-featured budget models to the fourth generation of its X Series line of AV receivers.

Available online now, the AVR-X1300W ($599) and AVR-X2300W ($799) are 7.2-channel models with Dolby Atmos surround sound (for 5.1.2 setups) that can also be upgraded to DTS:X surround sound via a free firmware update that will be available later this year. Rated power at 0.08 percent THD is 7 x 80 watts and 7 x 95 watt, respectively, and both models offer the Audyssey MultEQ XT automatic room acoustic measurement and correction system and Audyssey Dynamic EQ.

Common video features include support for HDMI 2.0a and HDCP 2.2, 4K/Ultra HD video up to 60Hz, 4:4:4 chroma sampling, high dynamic range (HDR), and BT.2020 pass-through on all inputs. Both models offer two HDMI outputs with six (X1300W) or eight (X2300W) HDMI inputs, one of which is on the front panel.

Common audio features include built-in Wi-Fi and streaming via Bluetooth and AirPlay, support for high-resolution audio files, and access to Internet Radio, Pandora, Spotify Connect, and SiriusXM.

The AVR-X2300W offers “advanced video processing with 4K scaling for 4K sources” and is certified by the Imaging Science Foundation for video quality. The receiver is also equipped with the full suite of ISFccc video-calibration controls and has Zone 2 pre-outs as well as an RS232 port for integration with home automation system.
