The catch
Sony STR-AZ5000ES
A busy gaming and display setup can run into the limit of four high-refresh inputs and two HDMI outputs.
Side by side
If compatible wireless rear speakers solve a real cable-route problem in your 7.1.4 room, Sony is the choice. Included full-bandwidth Dirac or a larger gaming-source collection points to RZ70. 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 buy
The room may have space for seven ear-level speakers plus four heights, yet a doorway or a busy path behind the seats can make the final speaker-wire run awkward. Sony supports certain wireless rear pairs assigned to Surround or Surround Back, which removes that run and keeps the planned layout intact. Those speakers still need a place to sit and power or charging. Onkyo supplies the eleven main amps, but its documented wired plan doesn’t get around the physical obstacle on its own.
Where this comes from
An eleven-channel layout, matched against Sony’s rear assignment and a path people use. Nothing here claims any wireless speaker brand will work or that operation is free of interference.
The catch
A busy gaming and display setup can run into the limit of four high-refresh inputs and two HDMI outputs.
The catch
In a 7.1.4 room, powered Zone 2 takes over the surround-back amplifiers. The front HDMI isn’t an extra high-refresh port.

Sony AZ5000ES vs Onkyo RZ70 for one-box 7.1.4, weighing rear cable routes, a crowded gaming setup and the hidden speaker cost of powered Zone 2.
Each of these eleven-amplifier receivers runs 7.1.4 with no separate main-room amp. What sets them apart is the cable route through the room and the gear your household plugs in.
Which one fits
Sony has compatible wireless rears as an option.
Six rear inputs on RZ70 are suitable.
Eleven main amplifiers are built into each.
Surround backs are switched off on Onkyo, unless the supported external zone route does the amplifying.

Two consoles, a gaming PC and another compatible source are enough to use up four fast inputs. RZ70 has two more high-refresh rear inputs. The extra front HDMI on Sony and the front AUX on Onkyo don’t stand in for high-refresh inputs. With only two gaming devices, this difference is worth nothing in practice. Before paying for capacity you won’t use, count the formats each source uses.
Six capable rear inputs against four, matched against the number of permanent sources. Input bandwidth is kept apart from total input count and temporary access.
RZ70 has terminals for a second room, but seven ear-level speakers and four heights already use up its eleven amps. In the documented powered Zone 2 assignment, the surround-back pair is turned off, which leaves 5.1.4 in the theater. If films and kitchen music regularly overlap, add a suitable external zone amp and read the zone source rules before you order. NET and Bluetooth can’t carry different internal programs across Onkyo zones, so an external amp by itself doesn’t give you a second independent network streamer.
11 main channels plus 2 zone speakers add up to 13 amplifier channels. The Onkyo manual specifies which pair gets borrowed, and it states the limit on a shared NET/Bluetooth source. No Sony advantage for simultaneous zones is claimed without verification.
Check a documented speaker layout against HDMI sources and external-amplifier plans.
Handles your setup
Runs 5.1.2 on its own built-in amplifiers. Takes 3 HDMI devices, 1 of them at 4K/120Hz. Use the four designated rear high-refresh inputs. The front input does not support 4K/120Hz.

A powered subwoofer does not count toward the speaker channels. This checks one main room. Check Zone 2, bi-amping and unusual speaker assignments yourself. Leave room for ventilation, and confirm HDMI settings, cables and speaker impedance before you install.

Sony, US black standalone receiver
A difficult speaker-wire run can be removed by compatible Sony rears, provided power or charging is available.

Onkyo, US black standalone receiver
Each of your five or six high-refresh sources needs its own rear input.
Spec by spec
| Spec | Sony STR-AZ5000ES | Onkyo TX-RZ70 | In practice |
|---|---|---|---|
| One-box main room | 7.1.4 | 7.1.4 | Neither needs a separate main-room amplifier for this layout. |
| High-refresh source inputs | Four | Six rear inputs | For compatible fast sources, Onkyo gives you two more direct routes. |
| Rear cable option | Specific compatible wireless rears | Wired rear layout documented | A cable path that extra sockets can’t fix is something Sony can deal with. |
| HDMI outputs | Two | Two monitor outputs plus Zone 2 | Onkyo includes a distinct physical zone output, which has its own format and source limits. |
Trade-offs
Change of plan
Go with Sony STR-AZ5000ES. Compatible wireless rears from Sony take care of the physical route.
Go with Onkyo TX-RZ70. Onkyo has six high-refresh inputs at the rear.
Decision guide
A complete theater in one receiver is the goal, but shared living-room access and several gaming sources pull the setup in different directions.
