TX-RZ830 is a 7.2.4-channel object-oriented audio device that implements proprietary Dynamic Audio Amplification technology and pass-through 4K video. The designers managed to implement a top-end digital architecture with large output currents with a power of 180 W/channel and in comparison with Onkyo TX-RZ900 where the power is equal only 140 W/channel, this power is enough for almost any home theater. TX-RZ830 is compatible with popular wireless audio platforms and can work in multi-room audio systems. It is also possible to broadcast content using the built-in Chromecast, DTS Play-Fi, or FlareConnect technologies.
TX-RZ900 is equipped with AK4458 DAC (32 bit/384 kHz), supports Dolby Atmos up to 5.1.2-channel configuration, as well as DTS: X format, which allows the use of additional ceiling speakers. The device uses a manually wound toroidal transformer and high-current discrete amplifiers, which allow reaching the lower limit of the frequency response of 5 Hz. An important aspect of the Onkyo TX-RZ830 vs Onkyo TX-RZ900 review is the ASR function, which compensates for the deterioration in the quality of compressed files, and the TX-RZ900 has such a function. The device supports Wi-Fi, Bluetooth, and AirPlay.
