Denon, 301130-01-00-101
AVR-S980H
Built for a TV and projector that share the same source, this seven-channel receiver has documented 1440p high-refresh input support. Powering speakers in a second room takes the amplifier channels that would otherwise go to rear or height speakers.
Best for5.1.2 rooms where a TV and projector share the system and a 1440p gaming route is confirmed
Why it suits you
- Main-room layouts of 5.1.2 or 7.1 are supported by seven built-in amplifier channels.
- Two HDMI monitor outputs carrying the same source, and six HDMI inputs of which three support 4K120.
- The US manual names 1440p100/120 as input formats outright. Higher bit depths require the documented 8K Enhanced setting.
What you give up
- The two HDMI outputs show the same source, so they cannot send different programs to two rooms.
- Once a second room is powered, five amplifier channels remain for the main room. Powered Zone 2 and 5.1.2 Atmos should not be planned together.

Yamaha, RX300ABL
RX300A
Five amplifiers cover either an ordinary surround setup or three front speakers plus two heights. The Atmos option helps when rear speakers are impractical to place, but this receiver cannot run five surround speakers and add heights at the same time.
Best forAn Atmos layout focused on the front, without having to buy a seven-channel receiver
Why it suits you
- Layout options of 5.1 and 3.1.2 come with five built-in amplifier channels.
- Four HDMI inputs and one eARC output, with 4K120/8K support documented under signal-format conditions.
- You can switch between two paired devices with Bluetooth Multipoint.
What you give up
- Five amplifiers handle 5.1 or 3.1.2 but not 5.1.2. To add two height speakers you give up the surround pair.
- Zone B, when powered, draws on the same amplifier pair as the surround or height speakers, leaving three main-room channels.

Yamaha, RX500A B
RX500A
In the same body size as the RX300A, this model keeps a five-speaker surround system and adds two heights. Network music is built in. Powered Zone B, however, still shares the main source and the height-speaker amplifiers.
Best forA five-speaker surround system with two heights, plus built-in Google Cast and supported network music
Why it suits you
- Main-room layouts of 5.1.2 or 7.1 run on seven amplifier channels.
- One eARC output and four HDMI inputs, with 4K120/8K formats documented.
- Wi-Fi and Ethernet are built in, along with Google Cast, AirPlay 2 and supported Spotify, TIDAL and Qobuz Connect services.
What you give up
- Two consoles, a player and a streaming box would already fill the four HDMI inputs, which could be limiting.
- Zone B plays the main-room source. Having its own volume does not mean a listener there can pick something different.

Marantz, US black standalone receiver
CINEMA 40
This nine-amplifier receiver suits a room with four heights, multiple subs and both a TV and a projector. It also converts supported older video sources to HDMI. Seven ear-level speakers plus four heights, though, still call for a separate amplifier.
Best forA media room that mixes old and new gear, with several subs and a stereo power amp that is already owned or planned
Why it suits you
- Eleven main processing channels and nine amplifiers.
- Seven rear high-refresh HDMI inputs and four independent sub outputs.
- Zone 2 HDMI plus two main HDMI outputs.
What you give up
- Two external amplifier channels are required for 7.1.4. Powering extra rooms also eats into the built-in amplifier budget.
- Audyssey XT32 is included, whereas Dirac is an optional upgrade you pay for.

Marantz, US black standalone receiver
CINEMA 30
A 7.1.4 room can run on the eleven built-in amplifiers alone, with no second power amp. Thirteen-channel processing offers a way to expand further, as long as you add external amplification and have suitable speaker positions.
Best forWired 7.1.4 theaters with several subs where thirteen main speakers are a realistic plan
Why it suits you
- Thirteen main processing channels and eleven amplifiers.
- Four sub outputs, each independent.
- One Zone 2 output, two main outputs and seven rear high-refresh HDMI inputs.
What you give up
- An external two-channel amplifier is still required for thirteen main speakers.
- Dirac licenses cost extra. Powering Zone 2 also cuts main-room amplification down to nine channels.

Onkyo, US black standalone receiver
TX-RZ70
One-box 7.1.4 and included full-bandwidth Dirac come together on this eleven-amplifier receiver. The front HDMI input is convenient but slower than the rear sockets, and extra-room playback comes with source and speaker-sharing limits.
Best for7.1.4 with one or two subs, for anyone who values included Dirac and easy-to-reach connections for visiting sources
Why it suits you
- Two sub outputs you can adjust separately, and eleven amplifiers.
- A limited 9 Gbps front input and six rear 40 Gbps HDMI inputs.
- HDMI outputs are separate for main, sub-monitor and Zone 2.
What you give up
- Eleven channels is the limit for main-room processing, so a power amp will not give you a 7.1.6 system.
- The front HDMI input has stricter format limits. And in a 7.1.4 setup, powering Zone 2 switches off the surround-back pair.

Yamaha, US black standalone receiver
RX-A2A
Seven source inputs and a separate Zone 2 audio path come with this seven-channel MusicCast receiver. A single display is the right match, but check the gaming hardware revision and what source feeds the second room before you buy.
Best forA MusicCast home with one display, 5.1.2 and a second room fed by non-HDMI sources
Why it suits you
- Seven HDMI inputs, three of them 24 Gbps high-refresh, and seven amps.
- MusicCast, MM phono and front left/right pre-outs.
- A separate amplifier can be driven from the external Zone 2 output, with source restrictions applying.
What you give up
- You get one HDMI output and seven main processing channels. Pre-outs that cover only the front do not make four-height Atmos possible.
- For high-refresh gaming, verify the HDMI board revision and firmware. Zone 2 cannot carry HDMI source audio, and powered speakers there use the amplifiers meant for the height pair.

Yamaha, US black standalone receiver
RX-A6A
A system that grows in stages is a good fit for nine built-in amplifiers and eleven-channel processing. Seven high-refresh inputs and analog-video conversion can tidy up a crowded media cabinet. A separate amplifier is needed for 7.1.4.
Best forMusicCast homes that reuse a stereo amp or pair current gaming gear with older video sources
Why it suits you
- Full pre-outs, eleven main processing channels and nine amplifiers.
- Three outputs and seven 40 Gbps HDMI inputs.
- Two subs that can be configured separately, plus YPAO multipoint calibration and MusicCast.
What you give up
- External power is needed for the front or rear-presence pair in a 7.1.4 layout.
- Eleven main channels is the processing limit, so extra power amps cannot add six heights to seven ear-level speakers.

Yamaha, US black standalone receiver
RX-A8A
A 7.1.4 MusicCast room is possible with the eleven built-in amplifiers and no separate power amp. The additional amplification neither raises the eleven-channel processing ceiling nor adds inputs beyond what the A6A has.
Best forSeven high-refresh sources feeding a MusicCast 7.1.4 system in one box
Why it suits you
- Eleven main processing channels and eleven amplifiers.
- Three outputs and seven 40 Gbps HDMI inputs.
- Analog-video to HDMI conversion, MM phono, MusicCast and YPAO multipoint.
What you give up
- Processing stays capped at eleven main channels, and adding an amplifier will not make it a thirteen-speaker processor.
- A large receiver still needs ventilation and clearance for plugs. The extra amplifier channels only help if the speaker layout uses them.

Sony, US black standalone receiver
STR-AZ1000ES
Optional Sony wireless rears and two display outputs come with this seven-channel receiver. They can shorten the speaker-wire run across a shared room, but there are not enough channels for four physical height speakers.
Best forA 5.1.2 room that has a TV and projector, or where running cable to the rear speakers is hard
Why it suits you
- Seven amplified main channels handle 5.1.2 or 7.1.
- Two outputs along with six HDMI inputs and two high-refresh inputs.
- Current firmware is required for compatible Sony SA-RS3S or SA-RS5 rear speakers.
What you give up
- Just two HDMI inputs support 4K120, so six inputs do not add up to six high-refresh connections.
- There are no full main-channel pre-outs and no four-height layout. Compatible wireless rears must be bought separately.

Sony, US black standalone receiver
STR-AZ3000ES
With nine amplifiers, a five-speaker ear-level system can be joined by four physical height speakers. It has more high-refresh source connections than the AZ1000ES. Its subwoofer pre-outs, however, do not offer an upgrade path to an external amplifier.
Best forA finished 5.1.4 room with as many as four high-refresh sources and optional Sony wireless surrounds
Why it suits you
- Nine main channels, amplified.
- Two outputs along with six HDMI inputs and four high-refresh inputs.
- SA-RS3S or SA-RS5, both optional, can be assigned as Surround or Surround Back.
What you give up
- Full main-channel pre-outs are absent, and an external stereo amplifier will not turn this model into a 7.1.4 system.
- Compatible wireless rears are an optional add-on and are no substitute for four wired height speakers.

Sony, US black standalone receiver
STR-AZ5000ES
This eleven-amplifier Sony covers a complete 7.1.4 layout and adds full main pre-outs and an easy-to-reach front HDMI socket. Sony wireless-rear options carry over, and the count of four high-refresh inputs is the same as on the AZ3000ES.
Best for7.1.4 rooms that need Sony wireless-rear compatibility or complete external-amp connections
Why it suits you
- Full main-channel pre-outs and eleven amplified main channels.
- Four of the seven HDMI inputs, front input included, are 4K120-capable.
- DCAC IX and two HDMI outputs.
What you give up
- It has four high-refresh inputs rather than seven, and the front input is not a 4K120 connection.
- 7.1.6 is beyond what eleven main channels can run. Compatible wireless rears and subs are sold separately.

Sony, US black standalone receiver
STR-AZ7000ES
No separate power amplifier is needed to run a 7.1.6 or 9.1.4 layout, thanks to the thirteen built-in amplifiers. This pays off when the room has suitable extra speaker positions. It is not an automatic upgrade for a 7.1.4 system that stays as it is.
Best forThirteen-speaker theaters in the planning stage that want to avoid an extra power amplifier
Why it suits you
- Full main pre-outs and thirteen amplified main channels.
- Layouts of 7.1.6 and 9.1.4 are documented.
- Two outputs, and seven HDMI inputs counting the front one, with four high-refresh inputs.
What you give up
- Appropriate speaker placement is needed to use the extra channels, and they do not by themselves mean better sound from an unchanged room.
- It keeps four high-refresh HDMI inputs and two HDMI outputs, since more amplifiers add no source or display connections.

Integra, US black standalone receiver
DRX-5.4
Included Dirac and eleven-channel pre-outs for a later external-amp upgrade come with this nine-amplifier receiver. Connections suited to installers do not lift the speaker-sharing and input restrictions that apply to multiroom playback.
Best forWired 5.1.4 installations that want included Dirac and plan to add a stereo amp for 7.1.4
Why it suits you
- Built-in amps number nine, with 11.2 pre-outs.
- Two display outputs and seven HDMI inputs, among them a limited front HDMI.
- Dirac Live Room Correction comes included.
What you give up
- A separate stereo amplifier is needed for 7.1.4, and powering Zone 2 can still take away a height pair.
- With the documented 5.1.4 and 7.1.4 layouts, Zone 3 pre-outs cannot be used. Bass Control is an optional upgrade you pay for.
Buying advice
What to look for in a AV receiver
These factors change which model suits you.
How many speakers need amplifier power
A receiver may process more channels than it amplifies. So rely on the documented external-amplifier layout. The number printed beside the subwoofer outputs can mislead. For reference, 5.1.4 means nine main speakers and 7.1.4 means eleven.
Which HDMI inputs count
A receiver with six HDMI inputs may not offer six 4K120 inputs. The front socket meant for temporary devices can top out at a lower video ceiling, and when both screens are on, two display outputs may be held to shared resolution limits.
Plan for ventilation around the receiver
Measuring the chassis height is just the start. You also need room for antennas, speaker plugs, bent HDMI cables and the clearance the manufacturer specifies for ventilation.
What calibration is included and what costs extra
Which version of Audyssey, YPAO or AccuEQ you get depends on the receiver. A Dirac-ready label does not mean a license or a measurement microphone is included. Likewise, independent subwoofer outputs are not the same as two jacks carrying one signal.
