Having had an opportunity to test Denon AVR-S540BT 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 - 5.2 versus 2.0, respectively, for devices. In terms of power, there are differences, the AVR-S540BT has such a ratio W/Ohm - 70/8, 90/6, while the R-N602BL has a power of 115/8, 105/4. The value of total harmonic distortion is also different, and for the AVR-S540BT it is 0.08%, but for the R-N602BL it is 0.01%.
The manufacturer installed different DACs, the AVR-S540BT received the model 192 KHz/32-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.
Wireless Internet connection via WIFI is only possible with R-N602BL. Each of the receivers has a Bluetooth connector. Access to the Spotify service is on each of the competitors. The number of available streaming services varies for receivers, the Denon AVR-S540BT works with TIDAL, Pandora, but the Yamaha R-N602BL works with Deezer, TIDAL, Pandora, Napster, SiriusXM, Qobuz.
Support for the HDR function can only boast of the AVR-S540BT. HDMI signal transmission in standby mode can provide only the AVR-S540BT. None of the devices can increase the resolution of the incoming video signal. Operation with the Dolby Vision is only possible with the AVR-S540BT. HDMI Audio Return Channel is only available on Denon AVR-S540BT. HDMI eARC is not supported by the AVR-S540BT and the R-N602BL. When comparing receivers, it becomes clear that only the Denon AVR-S540BT 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 either AV receiver. The Denon AVR-S540BT can be properly configured using the setup assistant.
