Choosing among AV receivers & amplifiers comes down to a few competing priorities: do you need 5.2 or 7.2 channels, a named format such as Dolby Atmos, multi-zone audio, or connection terms such as 8K HDMI and eARC? The four choices here split those needs across two Yamaha 7.2-channel models, a Yamaha 5.2-channel model, and a Sony 7.2-channel home theater receiver. Use the quick take to narrow the brief, then read the product notes for condition and package trade-offs.
Quick take
- For 8K HDMI, MusicCast, Wi-Fi, and eARC: Yamaha RX-V4A.
- For Dolby Atmos and DTS:X with Wi-Fi and Bluetooth: Yamaha TSR-7850.
- For multi-zone audio and an original remote: Yamaha RX-V675.
- For the lowest listed price and an AM, AUX, composite, and RCA input mix: Sony STR-DH750.
The prices span a $199.04 spread from lowest to highest. That difference matters, but each receiver has a different title-led use case; dollar order should not be treated as a performance ranking.
Listed-price comparison
| Receiver | Listed price | Price bar |
|---|---|---|
| Yamaha RX-V4A 5.2-Channel AV Receiver | 8K HDMI - MusicCast - Wi-Fi - eARC | $348.99 | |
| Yamaha RX-V675 7.2 Channel AV Receiver Multi-Zone w/Remote Bundle Tested Working | $198.00 | |
| Yamaha TSR-7850 7.2-Channel AV Receiver Dolby Atmos DTS:X WiFi Bluetooth | $289.99 | |
| Sony STR-DH750 7.2 Channel Home Theater Bluetooth AV Stereo Receiver TESTED | $149.95 |
Decision matrix
- Channel count: RX-V4A is named as 5.2; RX-V675, TSR-7850, and STR-DH750 are named as 7.2. This is a format difference, not a claim that one sounds better.
- Named cinema formats: TSR-7850 is the only title that names Dolby Atmos and DTS:X.
- Multi-zone: RX-V675 explicitly names multi-zone; the TSR-7850 description names MusicCast multi-room audio, which is a different phrase.
- Connection emphasis: RX-V4A names 8K HDMI and eARC; Sony's attributes name AM, AUX, composite, and stereo L/R RCA inputs.
Product notes
Yamaha RX-V4A 5.2-Channel AV Receiver
The RX-V4A suits a setup where the package matters as much as the receiver: the description includes a remote, power cord, AM and FM antennas, and a YPAO microphone. Its input list covers HDMI, Ethernet, USB, coaxial digital, optical digital, stereo L/R RCA, and subwoofer pre-out/LFE; outputs include banana speaker jacks, HDMI, a headphone jack, and raw-cable speaker jacks. The limitation is clear: it is open box and carries the $348.99 listed price, the highest in this comparison. Choose it for the included accessories and connection list; choose another if that condition or price does not fit.
Yamaha RX-V675 7.2 Channel AV Receiver Multi-Zone
The RX-V675 gives a shopper a straightforward multi-zone brief and includes the original remote control and power cord. The description also says the unit was tested and working, while the title identifies a 7.2-channel receiver. Its limitation is cosmetic and practical: scratches and scuffs are mentioned, the Zone 2 button has red marker, and HDMI, RCA, speaker, and other audio/video cables are not included unless shown. At $198.00, it is $48.05 above the Sony. This is the sensible match when multi-zone and the remote bundle matter more than Dolby Atmos or DTS:X wording; the used condition remains part of the decision.
Yamaha TSR-7850 7.2-Channel AV Receiver Dolby Atmos DTS:X
The TSR-7850 is the focused choice for a shopper who wants the title's Dolby Atmos and DTS:X labels alongside Wi-Fi, Bluetooth, and MusicCast multi-room audio. The description also names Cinema DSP 3D, YPAO auto calibration, and multiple HDMI inputs and outputs. Its limitation is the $289.99 price and Very Good - Refurbished condition; it sits above the RX-V675 and below the RX-V4A in listed price, but that order does not establish sound quality. Choose it when those named formats and wireless features define the brief. If a 5.2-channel receiver is the intended format, the RX-V4A is the differently configured Yamaha.
Sony STR-DH750 7.2 Channel Home Theater Bluetooth AV Stereo Receiver
The STR-DH750 makes the clearest price-led case: its $149.95 listed price is the lowest here, while the title pairs 7.2 channels with Bluetooth and a tested designation. The connection mix names AM, AUX, composite, digital coaxial, HDMI, stereo L/R RCA, and two-channel RCA inputs, plus banana speaker jacks, optical, HDMI, raw-cable, RCA, and stereo L/R RCA outputs. Its limitation is the used condition, described as overall good used condition. Choose Sony when the lower listed price and analog connections are the priority; choose a Yamaha when a title-specific feature such as multi-zone or Dolby Atmos leads the brief.
Final recommendation by use case
- 8K HDMI, eARC, and MusicCast: Yamaha RX-V4A.
- Dolby Atmos, DTS:X, and wireless audio terms: Yamaha TSR-7850.
- Multi-zone audio with an included remote: Yamaha RX-V675.
- Lowest listed price with the named AM, AUX, composite, and RCA input mix: Sony STR-DH750.
There is no single fit across all four: the RX-V4A is 5.2-channel, while the other three are named 7.2-channel models. Match the receiver to the format and connection language your room actually calls for, then weigh the stated condition and included accessories.
