I have tested these two receivers to help you find the solution that meets your demands. These models have many common features which make the choosing process challenging.
The VSX-LX303 works with Sonos and it uses the Phase Control feature (to exclude the phase lag) – compare it with the TX-NR676 that uses the Vector Linear Shaping Circuitry technology to output the clear sound. Both models have 32-bit DACs installed. These models output the clear 4K video with saturated colors. The Pioneer VSX-LX303 vs Onkyo TX-NR676 power comparison also shows that the VSX-LX303 is more powerful with its 900 W, while the TX-NR676 outputs 700 W.

Some customers have issues with the TX-NR676 ports –some units have non-reliable HDMI boards installed.
The VSX-LX303 uses the MCACC technology and the TX-NR676 uses the AccuEQ feature for the automatic audio calibration. The calibration process does not last long. Both manufacturers provide you with microphones. Some customers prefer to fine-tune the settings – you can do it using a special menu.
