Choosing among AV receivers & amplifiers is less about finding one universal winner than matching the receiver to your system: immersive audio formats, video connectivity, network audio, included controls, or simply a lower listed price. The four choices span a $289.00 listed-price spread, so the feature priorities matter as much as the price. The 7.2 and 5.2 channel figures are layout descriptions; they do not, by themselves, establish which receiver is better.
Quick take
Start with your must-have: immersive formats, 8K and eARC labels, multi-room audio, or the lowest listed price. The Yamaha TSR-7850 and Sony STR-DN1080 focus on home theater formats, the Yamaha RX-V4A emphasizes video and network features, and the Yamaha RX-V663 keeps the choice centered on HDMI and traditional surround formats. Use the matrix and notes below to narrow the fit without treating channel count as a quality ranking.

Product notes
Yamaha TSR-7850 7.2-Channel AV Receiver Dolby Atmos DTS:X WiFi Bluetooth
The Yamaha TSR-7850 is the direct match for a system that specifically calls for both Dolby Atmos and DTS:X. It also lists 7.2-channel surround, Wi-Fi, Bluetooth, MusicCast Multi-Room Audio, USB/AUX, multiple HDMI inputs/outputs, and YPAO Auto Calibration, giving the home theater several clearly named features to work with. The practical limitation is its Very Good - Refurbished condition. Its 7.2 figure describes channel layout only; it is not enough to declare this receiver superior to a 5.2 receiver.
Sony STR-DN1080 Dolby Atmos Home Theater Multi Channel AV Receiver Bluetooth
Sony's STR-DN1080 suits a home theater centered on Dolby Atmos, Bluetooth, and HDMI audio input/output. The model is also identified as a multi-channel AV receiver, keeping its role focused on surround use rather than a narrow stereo setup. The concrete drawback is the package: no remote is included, and the used condition may include scratches, scuffs, or marks. Choose it when those tradeoffs fit your setup and the named Atmos and HDMI combination matters more than having remote control included.
Yamaha RX-V4A 5.2-Channel AV Receiver
The Yamaha RX-V4A is the clearest match for the title's 8K HDMI, MusicCast, Wi-Fi, and eARC focus. Its 5.2-channel layout is accompanied by a wide connection list: Ethernet, HDMI, optical and coaxial digital, RCA, USB, speaker outputs, headphone jack, and subwoofer pre-out/LFE. Open-box condition and the included remote, power cord, and AM/FM antennas define the purchase. The limitation is its position at the highest listed price, so its appeal depends on needing those named connection and feature priorities.
Yamaha RX-V663 AV Surround Receiver w719
Yamaha's RX-V663 is the straightforward pick when the lowest listed price and a supplied remote and power cable matter most. It identifies HDMI input/output and Dolby Surround and DTS formats, making the intended use a conventional AV receiver setup. The tradeoff is the used condition, and its title centers on the RX-V663 model rather than calling out Dolby Atmos, DTS:X, 8K HDMI, Wi-Fi, or eARC. That makes the choice about the named feature set, not an assumption beyond its listed formats and connections.
Final recommendation by use case
- For Dolby Atmos and DTS:X together: choose the Yamaha TSR-7850, whose title and description name both formats along with Wi-Fi, Bluetooth, and MusicCast Multi-Room Audio.
- For Dolby Atmos with Bluetooth and HDMI input/output: choose the Sony STR-DN1080, provided the missing remote is acceptable.
- For 8K HDMI, eARC, and the broadest listed connection range: choose the Yamaha RX-V4A.
- For the lowest listed price with a remote, power cable, HDMI, Dolby Surround, and DTS: choose the Yamaha RX-V663.
