Both Onkyo devices at the first sight might seem identical. After practical checking, I paid attention to a difference between operational power consumptions. TX-RZ730 has 760W, and TX-NR686 – 570W. Moreover, the Onkyo TX-RZ730 vs Onkyo TX-NR686 comparison and testing allowed me to get a clearer picture of these receivers.
Both creations have Wi-Fi and Bluetooth, but while connecting with the smartphone there some problems appeared. Onkyo TX-NR686 refused to see the phone and the problem was solved after resetting of the receiver. With Onkyo TX-RZ730 also were some issues, actually, I’m talking about the app, which wasn’t user-friendly.
The setting on-screen guide was equal at both devices. When I decided to compare Onkyo TX-NR686 vs TX-RZ730, I found out that both of them have 3 aux inputs on the front panel. There was one unpleasant feature: in TX-NR686, the HDMI input was a little bit shattered. Perhaps, this was a problem of an assembly, but in practice, it was uncomfortable to use it and worry about frequent cord falling outside.
The aesthetic compare of Onkyo TX-RZ730 vs TX-NR686 was easy because both have a presentable appearance, but the display of the first unit seemed to be more bright and precise. Showed information was visible even from the other side of the room and the second device demonstrated less color saturation. The figures on TX-NR686 were a little bit smaller than on TX-RZ730.
