7 channel Amplifier: Onkyo TX-RZ810 features 7 channel power amplifier. It is rated at 130 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.	5 channel Amplifier: Sony STR-DH590 features 5 channel power amplifier. It is rated at 90 W (6 Ω, 20 Hz - 20 kHz, 2 channel driven).

• Dynamic Audio Amplification: Onkyo TX-RZ810 features Dynamic Audio Amplification which is Onkyo’s amplification philosophy that focuses on capturing the energy and dynamism contained in the audio signal and reproducing it without loss. Audio signals are not static like a test tone, but rather a countless collection of constantly moving waves. While static measurements such as S/N ratio and Total Harmonic Distortion are important, Onkyo believes that excellent dynamic and transient response is the key to emotionally involving sound. Dynamism - the “life” in music - is achieved when the amp can respond to changes in the signal instantaneously, so notes start and stop naturally and the nuances in attack, decay, sustain, and release are voiced with conviction. Onkyo home theater receivers represent the culmination of almost 70 years’ experience in amplifier design. The unique elements of their amplification system comprise high-current, low-impedance architecture to accurately control large speaker cones while enabling instantaneous response to dynamic changes, and discrete wide-range amplifier circuit topology to eliminate phase shift for clear and accurate audio imaging.

THX™ Select™2 Plus certification

Onkyo TX-RZ810 is THX™ Select™2 Plus certified. This means that it is ideally suited for a room where the screen-to-seat viewing distance is approximately 3 to 4 meters, and the room size is approximately 56 cubic meters.

Bi-amp Capability

Onkyo TX-RZ810's and Sony STR-DH590's amplifiers can be assigned for different speaker configurations.

• Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
Onkyo TX-RZ810: 5.2.2 with internal amplifier.
Sony STR-DH590: Not supported.
• DTS:X Configurations: The following speaker configurations are supported for DTS:X:
Onkyo TX-RZ810: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.
Sony STR-DH590: Not supported.
• Configurations without height channels: There are also other speaker configurations available which do not include height channels:
Onkyo TX-RZ810: 5.2, 7.2 with internal amplifier.
Sony STR-DH590: 5.2 with internal amplifier.
• Bi-Amp: Onkyo TX-RZ810 is able to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.

Dolby Atmos

Onkyo TX-RZ810 supports Dolby Atmos.

• Dolby Surround Upmixer: Onkyo TX-RZ810 supports Dolby Surround Upmixer. If the content is not mixed in Dolby Atmos then the Dolby surround upmixer will expand the audio to all channels including ceiling speakers. The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.

DTS:X

Onkyo TX-RZ810 supports DTS:X.

• DTS Neural:X: Onkyo TX-RZ810 supports DTS Neural:X which is an advanced upmixer that can take non DTS:X content and upmix it to the DTS:X speaker layout. It has replaced the DTS Neo family with improved flexibility.
• DTS Dialog Control: Onkyo TX-RZ810 supports DTS Dialog Control. This function adjusts the dialog levels during playback of the DTS:X stream. It allows you to separately increase the dialog levels in contrast with the background sound and hear dialog easily even under noisy circumstances.

Sony STR-DH590 comes with 4 HDMI inputs. It has 1 output.

• 4K/60Hz Passthrough: On both receivers all inputs pass up to 4K/60p (YCbCr4:4:4) video signal.
• 4K Upscaling on Onkyo TX-RZ810: It can upscale 1080p to 4K from HDMI and analog sources.
• Analog To HDMI Upconversion: Onkyo TX-RZ810 supports analog to HDMI Upconversion, so you can input your analog video sources and output them digitally via HDMI. This means that you will need only one HDMI cable to connect to your TV.
• BT.2020 Color Space: BT.2020 or Rec. 2020 is a color standard which delivers a wider color gamut compared to Rec. 709. It covers approximately 75% of the total visual spectrum while the Rec. 709 covers only 35% (available on both models).
• HDCP 2.2 Copy Protection: Both receivers are HDCP 2.2 compliant which is a requirement for 4K/HDR copy-protected content transmission.
• 3D Ready: Both receivers are able to pass 3D video through HDMI.

HDR (High Dynamic Range)

Onkyo TX-RZ810 supports HDR10 and Dolby Vision.

Sony STR-DH590 supports HDR10, Dolby Vision and Hybrid Log-Gamma. High dynamic range video has greater dynamic range than standard dynamic range (SDR) video with brighter whites and deeper blacks. The result is greater contrast and more details in dark and bright areas, better color and depth.
