Onkyo TX-RZ740 review

It has 9.2 channels and power output of 100W at 8 ohms. The AV receiver has seven HDMI inputs and two outputs that support 4K video transmission with Dolby Vision and HDR10 technologies. A signal with 1080p parameters supplied to these inputs can be converted up to 4K resolution. Onkyo TX-RZ740 has a high-end audio circuit using proprietary technology of dynamic amplification (Dynamic Amplification), which operates in an extended frequency range. Fans of Sonos will be glad to know that the novelty via Wi-Fi can easily integrate with the devices of their favorite brand. Onkyo TX-RZ740

Onkyo TX-NR797 review

Just like its opponent the Onkyo TX-NR797 receiver has 9.2 channels and power output of 100W at 8 ohms. Dolby Atmos and DTS:X map sounds in the movie to their corresponding positions in your room, so audio is localized or free move among your speakers and around the audience in sync with the action on screen. This 9.2-ch receiver expands object-based sound-field coverage with a 5.2.4 or 7.2.2-ch layout. Enjoy classic titles through your height-enabled system with Dolby Surround and DTS Neural:X upmixers for legacy soundtracks. Onkyo TX-NR797

Onkyo TX-RZ740 pros & cons

Pros

  • This unit has more features than I'll ever use in this lifetime
  • The set-up screen is "easy" as these things go, but watch the impedance settings

Cons

  • The only audio short-coming of this unit I ran into is that it's audio return channel is the older ARC, not the newer eARC necessary to return Dolby TrueHD (Atmos)

Onkyo TX-NR797 pros & cons

Pros

  • The graphic overlay that I wanted is definitely nice to have
  • Chromecasting works great, and I can add the receiver to my speaker group for whole-home playback

Cons

  • This machine has the most disappointing Bluetooth connectivity issues I have encountered and especially when it is such an expensive item
