Marantz SR8012 vs Onkyo TX-RZ3100

Marantz SR8012 review

Marantz SR8012 is based on discrete current-feedback HDAM amplifiers. As a result, it produces 205 W/channel at 6 Оhm. The flagship can decode object-oriented formats of Dolby Atmos, DTS: X and Auro-3D. For auto-calibration, the Audyssey MultEQ XT32 system is used, which is complemented by a set of Audyssey technologies. There is Wi-Fi (two bands), Bluetooth and AirPlay. The device can also be integrated into the HEOS multi-room system and controlled using a mobile application. The main difference between the devices in the Marantz SR8012 vs Onkyo TX-RZ3100 comparison is the ability to switch between speaker sets in the SR8012.
