Yamaha expands its RX-V 81 line of AV receivers with four models that support the latest video standards. Three of the new AVRs—the RX-V581 ($550), RX-V681 ($650), and RX-781 ($850)—are 7.2-channel designs that feature Dolby Atmos and DTS:X.

The RX-V481 ($450) is a 5.1-channel unit that handles Dolby True HD and DTS HD Master Audio formats. The new AVRs come on the heels of the recently announced entry-level RX-V381 ($300). All 2016 RX-V models include HDMI 2.0a, which means they can handle 2160p video at 60 fps with 4:4:4 color as well as high dynamic range (HDR) content.These new AVRs feature Bluetooth for wireless music playback from smartphones and tablets. You can also stream Bluetooth from the receiver to Bluetooth devices in the same area.

Support for Yamaha's MusicCast multi-room music streaming ecosystem comes standard on the newly-announced AVRs, only the (already shipping) RX-V381 lacks it. They also all include Yamaha's YPAO automatic room calibration system and a measurement microphone.
As far as nitty-gritty specs go, the RX-V481 is a 5.1-channel AVR that promises to deliver 80 watts of power into 8 ohm speakers with 0.09% THD (2 channels driven). The RX-V581 has the same 2-channel spec, but is a 7.2-channel AVR. The 7.2-channel RX-V681 offers a bit more power and lower distortion, with 90 watts of 8-ohm power and 0.06% THD (2 channels driven). Finally, the 7.2-channel RX-V781 offers a marginal improvement in output versus its underling with 95 watts of 8-ohm power and 0.06% THD (2 channels driven).
