Having had an opportunity to test Onkyo TX-SR343 vs Yamaha R-N602BL, I’d like to share my impression here to facilitate your choice of a new AV receiver.
The number of channels for receivers is different - 5.1 versus 2.0, respectively, for devices. In terms of power, there are differences, the TX-SR343 has such a ratio W/Ohm - 100/6, while the R-N602BL has a power of 115/8, 105/4. The value of total harmonic distortion is also different, and for the TX-SR343 it is 0.08%, but for the R-N602BL it is 0.01%.
The manufacturer installed different DACs, the TX-SR343 received the model TI Burr-Brown 192 KHz/24-bit, but the R-N602BL is equipped with Burr-Brown 192 KHz/24-bit. None of the compared opponents supports Bi-amping. The model R-N602BL can transmit an audio signal directly to the amplifier and bypasses any DSP processing. None of the AV receivers have an auto speaker calibration support.
Wireless Internet connection via WIFI is only possible with R-N602BL. Each of the receivers has a Bluetooth connector. The R-N602BL has access to the Spotify service.

None of the devices can increase the resolution of the incoming video signal. Review participants do not have the Dolby Vision feature. HDMI Audio Return Channel is only available on Onkyo TX-SR343. HDMI eARC is not supported by the TX-SR343 and the R-N602BL. When comparing receivers, it becomes clear that only the Onkyo TX-SR343 has HDMI CEC. In the presence of a built-in phono stage for connecting a vinyl player only at Yamaha R-N602BL. Voice control of the basic functions of the receiver is not realized in both models. There is an ECO mode in R-N602BL. None of these units can be properly configured using the setup assistant.
