Choosing av receivers & amplifiers is less about chasing a single power number and more about matching the unit to the system you are building. The real split here is between Dolby Atmos and networked features, a receiver with a wide mix of connections, and a new 5.1-channel amplifier. The listed spread is $140.04 from the lowest to highest price, so the right pick depends on the features and format you will actually use.
Quick take
- Yamaha TSR-7850: choose for a feature-led receiver brief.
- Sony STR-DN1080: choose when an Atmos-focused used receiver fits.
- Sony STR-DH750: choose when connection flexibility comes first.
- Darupsun SR8800: choose when a new amplifier format is the goal.

Product notes
Sony STR-DN1080 Dolby Atmos Home Theater Multi Channel AV Receiver Bluetooth

At $169.99, the Sony STR-DN1080 gives Dolby Atmos and multi-channel home theater language a clear place in the comparison without reaching Yamaha's listed price. Bluetooth is also named, and its HDMI, network connectivity, and speaker-output functions are identified as tested. That makes it a sensible match for a buyer prioritizing an Atmos receiver with wireless and HDMI-oriented features. The limitation is the Used condition: cosmetic scratches, scuffs, marks, or other signs of previous use may be present, and the remote control is not included. It suits someone comfortable with a previously used unit and a separate control solution.
Yamaha TSR-7850 7.2-Channel AV Receiver Dolby Atmos DTS:X WiFi Bluetooth

Yamaha's TSR-7850 is the feature-led receiver for a shopper who wants several named ways to build out a home theater: 7.2-channel surround sound, Dolby Atmos, DTS:X, Wi-Fi, Bluetooth, MusicCast multi-room audio, USB/AUX input, Cinema DSP 3D, and YPAO Auto Calibration. That collection gives it a specific role in a connected home theater or multi-room setup. Its listed price is the highest in the group, so the feature list comes with the widest monetary commitment. It is marked Very Good - Refurbished rather than New. Choose it when multi-room and processing features matter more than minimizing the listed price.
Sony STR-DH750 7.2 Channel Home Theater Bluetooth AV Stereo Receiver TESTED

Connection flexibility is the Sony STR-DH750's clearest reason to choose it. The listed inputs include AM, AUX, composite, digital coaxial RCA, HDMI, stereo L/R RCA, and two-channel RCA; the outputs include banana speaker jacks, digital optical TOSLINK, HDMI, raw-cable speaker jacks, RCA, and stereo L/R RCA. That mix gives a shopper a concrete way to accommodate varied equipment. The limitation is its Used condition, even though *TESTED* is part of the title. At $149.95, it is the lowest-priced receiver in this comparison, making the broad connection list its strongest practical draw.
3600W Peak Stereo HiFi Power Bluetooth Amplifier High-Power 5.1 Subwoofer Home

Darupsun's SR8800 is the distinct format here: a New, 5.1-channel stereo HiFi power amplifier with Bluetooth, a 3600W peak phrase in the title, and a listed 1V auxiliary level output. Choose it when you specifically want an amplifier rather than a receiver and the 5.1 layout fits your plan. The limitation is fit: it is presented as a power amplifier, while the other three titles present AV receivers. At $269.36, it is also close to the top of the listed price range. Keep the choice focused on its stated format, not on comparing the raw peak-watt number.
Final recommendation by use case
For a receiver-led home theater decision, start with the Yamaha TSR-7850 if its listed feature breadth fits the plan and its highest listed price is acceptable. If a Used unit and a remote that is not included are workable, Sony STR-DN1080 is the focused alternative. Choose Sony STR-DH750 when connection flexibility drives the decision. Choose Darupsun SR8800 when a New power-amplifier format is the requirement. Match the system format and condition first, then select the feature mix that serves your setup.
