Main trade-off
Integra DRX-5.4
7.1.4 requires external stereo power. Powered Zone 2 can remove a height pair even after that amp is added.
Head-to-head
Integra DRX-5.4 vs Onkyo TX-RZ70: RZ70 adds two amps and independent sub settings
The short answer
Choose RZ70 when you want one-box 7.1.4 or separate settings for two powered subs. RZ70 powers 7.1.4 without the extra stereo amplifier that DRX-5.4 needs. Integra remains a candidate for a nine-speaker room or a system with a suitable amp already installed. Neither powered Zone 2 arrangement automatically keeps all eleven main speakers active, and both need their exact simultaneous-use rules checked.
Before you choose
The reasoning and the trade-offs
Existing amplification decides whether the upgrade removes a real purchase
DRX-5.4 can process eleven main speakers but has nine internal amps. RZ70 has eleven. For a new 7.1.4 build, RZ70 removes the need to buy and install a stereo power amp. If a suitable amp is already installed, Integra can reuse it and the internal-channel difference may have little daily effect. Include cable routes, power and ventilation in that decision, not merely the number of boxes shown in a product photograph.
What this is based on
Eleven requested speakers minus nine internal amps equals two external channels. Existing installed equipment changes the purchase consequence.
Main trade-off
Onkyo TX-RZ70
Powered Zone 2 removes surround backs from 7.1.4. More internal amps do not eliminate simultaneous-zone limits.

About this comparison
Integra DRX-5.4 vs Onkyo RZ70 for included Dirac, 7.1.4 and second-room speakers. Compare hidden amplifier costs and which main speakers a zone can disable.
Both fit a Dirac-based eleven-channel theater. The practical upgrade is whether the extra main amplification and independent sub control are already covered by other equipment.

What matters in practice
The differences that matter
Existing amplification decides whether the upgrade removes a real purchase
DRX-5.4 can process eleven main speakers but has nine internal amps. RZ70 has eleven. For a new 7.1.4 build, RZ70 removes the need to buy and install a stereo power amp. If a suitable amp is already installed, Integra can reuse it and the internal-channel difference may have little daily effect. Include cable routes, power and ventilation in that decision, not merely the number of boxes shown in a product photograph.
How we reached this conclusion
Eleven requested speakers minus nine internal amps equals two external channels. Existing installed equipment changes the purchase consequence.
Second-room music takes a different part of the soundtrack
Integra documented 7.1.4 plus powered Zone 2 layout still turns off Height1 even with the required external stereo amp connected. RZ70 powered Zone 2 turns off surround backs in its 7.1.4 assignment. That means the extra amp alone is not proof that every theater speaker stays active while someone listens elsewhere. If this overlap happens often, plan a supported externally amplified zone route and verify the input source rules before ordering. The manuals, rather than terminal count, determine which channels remain.
How we reached this conclusion
Exact simultaneous assignment diagrams crossed with overlapping film and second-room listening. No claim that one missing pair is universally less important.
Two subs can need separate controls even though both receivers have two sockets
When two powered subs sit at different distances or need different levels, RZ70 supplies independent receiver adjustments. Integra paired outputs share the sub signal and setup. Existing external processing can change the practical difference, and current optional Bass Control support should not be confused with independently adjustable physical outputs. The gain is a control path that matches the installation. It is not a verified claim that RZ70 produces better bass in every room.
How we reached this conclusion
Shared versus independent output settings crossed with separate sub placement. Licensing, output routing and measured acoustics are kept distinct.

Integra DRX-5.4
Needs another check
The number of 4K/120Hz inputs has not been verified.
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.

Meaningful differences
What changes the fit
| What changes | Integra DRX-5.4 | Onkyo TX-RZ70 | Why it matters |
|---|---|---|---|
| Built-in main amps | Nine | Eleven | RZ70 avoids external main-room stereo power for 7.1.4. |
| Sub settings | Two shared outputs | Two independent outputs | RZ70 can adjust two subs separately inside the receiver. |
| Powered Zone 2 with 7.1.4 wiring | Height1 stops in the documented external-amp layout | Surround backs stop | Both have a compromise, but it affects different speakers. |
| Main processing ceiling | Eleven channels | Eleven channels | Neither becomes a thirteen-main-speaker processor with another amp. |
What you give up
Every choice has a cost
If you choose Integra DRX-5.4
- Bass Control Single is an optional paid upgrade and does not establish separately adjustable physical sub outputs.
If you choose Onkyo TX-RZ70
- Bass Control is optional. Eleven main processing channels remain the maximum.
Recommendation switch
The decision flips if...
The build needs two more internal amps or independent sub settings
Choose Onkyo TX-RZ70. RZ70 adds those capabilities.
What matters in practice
Before you choose
You want to reuse useful equipment without discovering that another room still takes speakers away from the theater.
What this comparison cannot tell you
- No unverified reason is invented to make Integra a performance winner. Price value depends on current offers and equipment already owned.
