Onkyo TX-RZ740 review

The Onkyo TX-RZ740 AV receiver received an 11.2-channel preamp output and 11-channel internal signal processing. The power is 9 x 185W (6 Ohms). Onkyo TX-RZ740 is equipped with decoders for all common surround sound formats, including Dolby Atmos and DTS: X. Based on this model, it is possible to build 3D systems in a configuration up to 5.2.4 without using external amplifiers. You can also create a virtual surround sound system and using Dolby Atmos Height Virtualizer technologies, the correct processing of IMAX content is also provided. Onkyo TX-RZ740

Onkyo TX-RZ840 review

This model has almost the same features as his opponent, but I’ll underline the differences. It is also a 9.2 channel receiver that delivers 180W (6 Ohms). Supports THX Certified Select certification, which indicates reference sound quality. The power supply unit is equipped with a powerful high-current transformer H.C.P.S. and large capacitors. The design utilizes Dynamic Amplification Technology (DAA), which provides high current and efficient noise reduction. AccuEQ Advance deals with the speaker calibration, eliminating standing waves in the listening area. Onkyo TX-RZ840

Onkyo TX-RZ740 pros & cons

Pros

  • I enjoyed FlareConnect for multi-zone audio distribution to compatible components
  • It is very massive and equipped with high capacitance capacitors

Cons

  • In comparison with the previous model, the number of optical inputs has decreased, and the developers have sacrificed component and composite video inputs as the least relevant

Onkyo TX-RZ840 pros & cons

Pros

  • The Onkyo TX-RZ840 is supremely feature rich
  • Vocal Enhancer technology solves the problem of hard-to-hear dialogue in television programs and films
  • Its massive chassis is filled with custom components that have been tested

Cons

  • The remote control is cheap and basic, it does the basic tasks but should offer more so you don't have to connect a TV
