For music lovers, it supports popular streaming services and smart home assistants, offering easy wireless connectivity through Bluetooth and Apple HomeKit compatibility.

The unit is quite heavy at nearly 58 pounds, which might make installation a bit challenging. While the power is ample for most, those with extremely large or challenging rooms may want even higher output. The Onkyo TX-RZ70 is a solid choice for users wanting a high-performance, feature-rich receiver that excels in sound quality, connectivity, and room adaptation, especially if you’re building a premium home theater setup with multiple zones and subwoofers.

The ability to work with Sonos is a nice touch, allowing integration with an existing Sonos system. However, the unit is quite heavy and large, which might be a drawback if space is limited.
