Onkyo TX-RZ730 review
The Onkyo TX-RZ730 is compatible with all multichannel, Dolby and DTS audio formats and as such supports the vertical formats Dolby Atmos, Dolby Digital Plus Atmos and DTS: X. This device delivers 175 W/channel versus the competitor can deliver 165 W/channel, but both have same impedance – 6 Ohm. The TX-RZ730 is equipped with an HDMI 2.0 controller, compatible with all video streams up to 2160p (Ultra HD-4K) and 60 frames per second, with BT.2020 and extended dynamic range (HDR Dolby Vision, HLG and HDR10). Also, it has wide network abilities as the TX-NR686.
Onkyo TX-NR686 review
Onkyo TX-NR686 can stream HD video through 4K HDR with Dolby Vision and HDDR10 standards. The device can complement the picture with DTS: X and Dolby Atmos soundtracks. Also, Dolby Surround and DTS Neural: X decoders can be involved in creating the surround sound. In our Onkyo TX-RZ730 vs Onkyo TX-NR686 review, the lack of multi-channel preamp out TX-N686 should be noted. However, users can stream music through the built-in wireless Chromecast, DTS Play-Fi or FlareConnect. AirPlay and Bluetooth technology are also on board. It is possible to use the built-in streaming services with dynamic and emotional sound.
