Choosing AV receivers & amplifiers gets tricky when three full receivers sit beside a cable that solves a completely different problem. The key question is whether your setup needs a 7.2-channel Dolby Atmos/DTS:X receiver, a 5.2-channel model with 8K HDMI and eARC, a multi-channel Bluetooth receiver, or simply a way to connect older RCA-equipped gear.
Start with connection type and channel count, then use features such as MusicCast, Wi-Fi, Bluetooth, and YPAO to narrow the match. That prevents choosing an AV receiver when a 1m composite cable is the actual fix-or expecting a cable to replace an amplifier.
Quick take
- Yamaha TSR-7850: The direct match for 7.2-channel surround sound with Dolby Atmos, DTS:X, MusicCast, Wi-Fi, and Bluetooth.
- Sony STR-DN1080: A Dolby Atmos multi-channel receiver with Bluetooth and HDMI input/output; the used condition and absent remote matter.
- Yamaha RX-V4A: A 5.2-channel choice centered on 8K HDMI, MusicCast, Wi-Fi, eARC, and a broad mix of listed connections.
- 3 RCA Male to Male Composite AV Cable: A 1m cable for standard composite video and stereo audio between compatible older equipment.
Listed-price comparison
The absolute listed-price spread is USD 344.80, and it reflects a cable-to-receiver comparison rather than four equivalent amplifiers.

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 7.2-channel surround system: Dolby Atmos and DTS:X are named alongside MusicCast multi-room audio, built-in Wi-Fi, Bluetooth, USB/AUX input, Cinema DSP 3D, and YPAO auto calibration. That mix gives shoppers several ways to build around the receiver, especially when wireless audio and room calibration matter. The concrete limitation is its Very Good - Refurbished condition, which sets it apart from the open-box and used choices here. Its listed audio input is HDMI, so shoppers whose sources depend on other connection types should weigh that stated input detail when planning the setup.
Sony STR-DN1080 Dolby Atmos Home Theater Multi Channel AV Receiver Bluetooth
The Sony STR-DN1080 suits a Dolby Atmos home theater that needs a multi-channel AV receiver with Bluetooth and HDMI input/output. It is marked Used and fully functional, with HDMI functionality, network connectivity, speaker outputs, and Bluetooth connectivity identified. The important limitation is practical rather than sonic: the remote control is not included. That makes the Sony a fit for shoppers who already have a way to control the receiver or are comfortable with the stated used condition. Its black finish and AM/FM band are additional listed details, but the missing remote and required connections should drive the decision more than appearance.
Yamaha RX-V4A 5.2-Channel AV Receiver
The Yamaha RX-V4A is the receiver to shortlist when the setup centers on a 5.2-channel format and features 8K HDMI, MusicCast, Wi-Fi, and eARC. Its connections include HDMI, Ethernet, coaxial and optical digital inputs, stereo RCA, USB, and subwoofer pre-out, while outputs include HDMI, headphone, and banana or raw-cable speaker connections. The clear limitation is the 5.2-channel count for anyone specifically planning 7.2 channels. It is also Open box, so condition belongs in the decision alongside the connection list. The included remote, power cord, and AM/FM antennas round out the named contents.
3 RCA Male to Male Composite AV Cable 1m for TV DVD Home Theater Audio Video
The 3 RCA Male to Male Composite AV Cable 1m is for a different job from the receivers. Its three RCA male connectors on each end carry standard composite video and stereo audio between compatible equipment such as TVs, DVD players, VCRs, game consoles, home theater systems, and AV receivers. Choose it when the needed link is a matching composite connection and the 1m length suits the setup. The limitation is equally clear: it requires matching RCA connections and handles a cable connection rather than amplification, Dolby Atmos processing, Wi-Fi, or speaker-channel management. It is the smallest purchase here, but it is not a receiver substitute.
Final recommendation by use case
- For 7.2-channel Dolby Atmos and DTS:X: Choose the Yamaha TSR-7850, particularly if MusicCast, Wi-Fi, Bluetooth, and YPAO are useful to your setup.
- For Dolby Atmos with Bluetooth and HDMI input/output: Choose the Sony STR-DN1080 if the Used condition and no-remote arrangement are acceptable.
- For a 5.2-channel system with 8K HDMI, eARC, Wi-Fi, and MusicCast: Choose the Yamaha RX-V4A, while keeping its Open box condition in view.
- For an older TV, DVD player, VCR, or compatible AV device with RCA connections: Choose the 3 RCA cable and its standard composite audio/video format.
If the decision is between a receiver and the cable, settle that first: the receiver models are intended for a surround setup, while the RCA cable is intended to carry standard composite audio and video.
