Denon AVR-S570BT vs Onkyo TX-RZ70 review
Having had an opportunity to test Denon AVR-S570BT vs Onkyo TX-RZ70, I’d like to share my impression here to facilitate your choice of a new AV receiver.
Amplifier
The number of channels for receivers is different - 5.2 versus 11.2, respectively, for devices. In terms of power, there are differences, the AVR-S570BT has such a ratio W/Ohm - 70/8, 90/6, while the TX-RZ70 has a power of 140/8. A common feature for devices is the same total harmonic distortion - 0.08%.
Audio features
The manufacturer installed different DACs, the AVR-S570BT received the model 192 KHz/32-bit, but the TX-RZ70 is equipped with 384 KHz/32-bit. The Bi-amping function is implemented only in the Onkyo TX-RZ70. Both Denon AVR-S570BT and Onkyo TX-RZ70 can transmit an audio signal directly to the amplifier and bypasses any DSP processing. Each of the receivers has a Bluetooth connector. The TX-RZ70 has access to the Spotify service.
Video features
The HDR10+ function is present in each of the rivals. The quality of 4K/120Hz signal remains unchanged when transmitting from a source to a TV or projector via HDMI for both receivers. Signaling over HDMI in standby mode can provide the AVR-S570BT and the TX-RZ70. Each of the devices can increase the resolution of the incoming video signal. Each of the participants of the comparison has a Dolby Vision.

HDMI Audio Return Channel is implemented in both devices. HDMI eARC is supported by the AVR-S570BT and the TX-RZ70. When comparing receivers, it becomes clear that each of the rivals can work with HDMI CEC. AVR-S570BT and TX-RZ70 support the standard HDCP 2.3. Unlike most receivers, our models do not have a built-in phono stage for connecting a vinyl player. There is an ECO mode in either AV receiver. The Denon AVR-S570BT and the Onkyo TX-RZ70 can be properly configured using the setup assistant.
