Sony STR-AZ5000ES vs Onkyo TX-RZ70: Sony eases rear wiring, Onkyo fits more fast sources

The short answer

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

The reasoning and the trade-offs

A complete theater can still have one impossible cable run

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

Sony STR-AZ5000ES

Four high-refresh inputs and two HDMI outputs can limit a busy gaming and display setup.

Main trade-off

Onkyo TX-RZ70

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

About this comparison

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.

What matters in practice

The differences that matter

A complete theater can still have one impossible cable run

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.

How we reached this conclusion

Eleven-channel layout crossed with Sony rear assignment and a used circulation path. No claim about unrestricted wireless speaker brands or interference-free operation.

The front socket does not rescue a fifth fast source

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.

How we reached this conclusion

Six versus four capable rear inputs crossed with permanent source count. Input bandwidth is separated from total input count and temporary access.

Kitchen music can turn 7.1.4 into 5.1.4

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.

How we reached this conclusion

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.

Your 5.1.2 layout needs 7 speaker channels. Your devices need 3 HDMI inputs, including 1 for 4K at 120Hz.

Sony STR-AZ5000ES

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.

Onkyo TX-RZ70

Supports your setup

Supports 5.1.2 using the receiver's own amplifiers. Connects 3 HDMI devices, including 1 at 4K/120Hz. Use the six rear inputs for 4K/120Hz. The front input has lower limits.

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.

What you give up

Every choice has a cost

If you choose Sony STR-AZ5000ES

  • Compatible wireless rear speakers are sold separately. The option does not remove all room cabling.

If you choose Onkyo TX-RZ70

  • Preserving all eleven main speakers during second-room playback requires a suitable external zone amp and supported input route.

Recommendation switch

The decision flips if...

The rear speaker cable path is the unresolved problem

Choose Sony STR-AZ5000ES. Sony compatible wireless rears address the physical route.

Five or six fast sources need receiver inputs

Choose Onkyo TX-RZ70. Onkyo provides six rear high-refresh inputs.

What matters in practice

Before you choose

You want a complete theater in one receiver, but shared living-room access and several gaming sources pull the setup in different directions.

Check these before buying

  • Confirm rear speaker assignment and power access.
  • List simultaneous main-room and zone sources, not just rooms.
  • Check US model, calibration accessories and seller terms.

What this comparison cannot tell you

  • No measured sound, calibration or wireless reliability ranking. Zone 2 has separate limits from main monitor playback.
