Choosing AV receivers & amplifiers starts with a fork: do you need a two-channel music receiver, multi-zone audio, or an HDMI-centered home theater model? A higher channel count does not automatically answer the connectivity question, while a simpler stereo unit may be the cleaner match for music. The useful shortcut is to match the receiver's named format and connections to your room before comparing prices.
Quick take
The four choices cover distinct use cases. Yamaha R-S202 is a 2-channel Bluetooth stereo receiver; Yamaha RX-V675 carries a 7.2-channel multi-zone title; ADCOM GTP 500 is a 5-channel multi-zone digital processor; and Yamaha RX-V4A combines a 5.2-channel format with 8K HDMI, MusicCast, Wi-Fi, and eARC. Condition also varies between used, open-box, and certified-refurbished units, so the lowest price is not the only decision point.

Product notes
Yamaha RX-V675 7.2 Channel AV Receiver Multi-Zone w/Remote Bundle Tested Working
The Yamaha RX-V675 is a direct fit when the 7.2-channel, multi-zone format is the starting requirement. The title uses Tested Working, and the package includes an original remote and power cord. Its connection details include HDMI, Ethernet, USB, digital coaxial RCA, and digital optical TOSLINK, giving it a clear reason to choose for a setup that needs several named input types. The limitation is condition: it is used, with scratches and scuffs noted, plus red marker on the Zone 2 button. HDMI, RCA, speaker, and other A/V cables are not included unless shown.
Yamaha RX-V4A 5.2-Channel AV Receiver | 8K HDMI - MusicCast - Wi-Fi - eARC
This Yamaha is aimed at shoppers whose shortlist specifically includes the title's 8K HDMI, MusicCast, Wi-Fi, and eARC terms. It is a 5.2-channel model, and its connection details name HDMI, Ethernet, USB, stereo RCA, optical digital, coaxial digital, HDMI output, banana speaker jacks, and raw-cable speaker jacks. That concentration of named AV and network features is the main reason to choose it. The trade-offs are concrete: $348.99 is the highest listed price, and the condition is open box. The package includes a remote, power cord, AM antenna, and FM antenna.
ADCOM GTP 500 AV Receiver 5-Ch. Multi Zone Digital Processor W/ Remote
ADCOM GTP 500 suits a shopper focused on a 5-channel, multi-zone digital processor and remote. Its multi-zone function is described as playing music in different areas simultaneously, while the connection details name a multi-channel RCA input, five inputs, and five outputs. Those details give it a specific reason to choose when the system is organized around RCA connections. The limitation is connection specificity: multi-channel RCA is the named audio-input type, so it is a narrower fit than the Yamaha choices that explicitly name HDMI, Ethernet, USB, or optical inputs. Its listed price is $110.95 above the R-S202.
Yamaha R-S202 2ch. Natural Sound 200W Bluetooth Stereo Receiver
The Yamaha R-S202 is the uncomplicated route for two-channel listening, especially when Bluetooth and a simple receiver layout are priorities. It includes 40-station FM/AM preset tuning and a speaker selector for two systems, making those concrete reasons to choose it for a music-focused setup. Outputs named for the unit include a headphone jack, DIN, and raw-cable speaker jacks. The limitation is format: the title identifies a 2ch Bluetooth stereo receiver rather than the 5.2- or 7.2-channel AV formats named elsewhere. Its condition is certified-refurbished, another relevant part of the decision.
Final recommendation by use case
- For a simple music system: Choose Yamaha R-S202. Its $159.00 listed price and certified-refurbished condition make the trade-off easy to understand.
- For a 7.2-channel multi-zone setup: Choose Yamaha RX-V675. The $198.00 price and included original remote are concrete reasons to favor this route.
- For the feature combination named on the RX-V4A: Choose Yamaha RX-V4A when 8K HDMI, MusicCast, Wi-Fi, and eARC are the deciding requirements and open-box condition fits your plan.
- For a multi-zone digital processor: Choose ADCOM GTP 500 when its multi-channel RCA input matches your system; its $269.95 price sits $110.95 above the R-S202.
Start with channel format and connections, then use the $189.99 overall price spread to decide how much of the range fits the system you are actually building.
