Main trade-off
Sony STR-AZ5000ES
Four high-refresh inputs and two HDMI outputs can limit a busy gaming and display setup.
Head-to-head
Choose Sony when compatible wireless rear speakers solve a real cable-route problem in your 7.1.4 room. Choose RZ70 for included full-bandwidth Dirac or a larger gaming-source collection. RZ70 can keep six high-refresh sources on rear inputs, compared with four on Sony. Both power 7.1.4, but Onkyo powered Zone 2 removes the surround-back pair while that zone is active.
Before you choose
Seven ear-level speakers plus four heights may fit the room, but a doorway or well-used path behind the seats can make the last speaker-wire route awkward. Sony supports specific wireless rear pairs assigned to Surround or Surround Back, so that route can be removed without abandoning the planned layout. Those speakers still need placement and power or charging. Onkyo provides the eleven main amps, but its documented wired plan does not solve that physical obstacle by itself.
What this is based on
Eleven-channel layout crossed with Sony rear assignment and a used circulation path. No claim about unrestricted wireless speaker brands or interference-free operation.

Main trade-off
Powered Zone 2 borrows the surround-back amplifiers from a 7.1.4 room. Front HDMI is not another high-refresh port.


Sony AZ5000ES vs Onkyo RZ70 for one-box 7.1.4. Compare rear cable routes, a crowded gaming setup and the hidden speaker cost of powered Zone 2.
These eleven-amplifier receivers both run 7.1.4 without a separate main-room amp. Their useful differences concern the room cable route and what the household connects.
Winner by situation
Sony offers compatible optional wireless rears.
RZ70 has six suitable rear inputs.
Both contain eleven main amplifiers.
Onkyo turns off surround backs unless the supported external zone route handles amplification.

A household can fill four fast inputs with two consoles, a gaming PC and another compatible source. RZ70 has two more high-refresh rear inputs available. Sony extra front HDMI and Onkyo front AUX are not high-refresh substitutes. If there are only two gaming devices, this difference has no practical value. Count the formats each source actually uses before paying for unused capacity.
Six versus four capable rear inputs crossed with permanent source count. Input bandwidth is separated from total input count and temporary access.
RZ70 has terminals for a second room, but its eleven amps are already occupied by seven ear-level speakers and four heights. The documented powered Zone 2 assignment turns off the surround-back pair, leaving 5.1.4 in the theater. If a film and kitchen music routinely overlap, use a suitable external zone amp and check the zone source rules before ordering. NET and Bluetooth cannot provide different internal programs across Onkyo zones, so an external amp alone does not create a second independent network streamer.
11 main channels plus 2 zone speakers need 13 amplifier channels. Onkyo manual specifies which pair is borrowed and its shared NET/Bluetooth source limitation. No unverified Sony simultaneous-zone advantage is asserted.
Check a documented speaker layout against HDMI sources and external-amplifier plans.
Supports your setup
Supports 5.1.2 using the receiver's own amplifiers. Connects 3 HDMI devices, including 1 at 4K/120Hz. Use the four designated rear high-refresh inputs. The front input does not support 4K/120Hz.

A powered subwoofer is separate from the speaker-channel count. This checks one main room. Zone 2, bi-amping and unusual speaker assignments need another manual check. Allow ventilation space and confirm HDMI settings, cables and speaker impedance before installing.

Sony, US black standalone receiver
Compatible Sony rears can remove a difficult speaker-wire run, with power or charging available.

Onkyo, US black standalone receiver
Five or six high-refresh sources need their own rear inputs.
Meaningful differences
| What changes | Sony STR-AZ5000ES | Onkyo TX-RZ70 | Why it matters |
|---|---|---|---|
| One-box main room | 7.1.4 | 7.1.4 | Both avoid a separate main-room amplifier for this layout. |
| High-refresh source inputs | Four | Six rear inputs | Onkyo offers two more direct routes for compatible fast sources. |
| Rear cable option | Specific compatible wireless rears | Wired rear layout documented | Sony can address a cable path that more sockets cannot fix. |
| HDMI outputs | Two | Two monitor outputs plus Zone 2 | Onkyo adds a separate physical zone output, with its own format and source limits. |
What you give up
Recommendation switch
Choose Sony STR-AZ5000ES. Sony compatible wireless rears address the physical route.
Choose Onkyo TX-RZ70. Onkyo provides six rear high-refresh inputs.
What matters in practice
You want a complete theater in one receiver, but shared living-room access and several gaming sources pull the setup in different directions.
