Having had an opportunity to test Denon AVR-X2500H 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 - 7.2 versus 2.0, respectively, for devices. In terms of power, there are differences, the AVR-X2500H has such a ratio W/Ohm - 95/8, 125/6, 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-X2500H it is 0.08%, but for the R-N602BL it is 0.01%.
The manufacturer installed different DACs, the AVR-X2500H received the model AK4490 384 KHz/32-bit, but the R-N602BL is equipped with Burr-Brown 192 KHz/24-bit. The Bi-amping function is implemented only in the Denon AVR-X2500H. Both Denon AVR-X2500H and Yamaha R-N602BL can transmit an audio signal directly to the amplifier and bypasses any DSP processing.
Wireless Internet access via WIFI is possible on both units. Each of the receivers has a Bluetooth connector. The contenders have differences in the supported services from Apple - AirPlay, AirPlay 2 versus AirPlay respectively. Access to the Spotify service is on each of the competitors. The number of available streaming services varies for receivers, the Denon AVR-X2500H works with Deezer, TIDAL, Pandora, Napster, SiriusXM, TuneIn Radio, iHeart Radio, Sound Cloud, but the Yamaha R-N602BL works with Deezer, TIDAL, Pandora, Napster, SiriusXM, Qobuz. HDMI signal transmission in standby mode can provide only the AVR-X2500H. None of the devices can increase the resolution of the incoming video signal. Operation with the Dolby Vision is only possible with the AVR-X2500H. HDMI Audio Return Channel is only available on Denon AVR-X2500H. HDMI eARC is not supported by the AVR-X2500H and the R-N602BL. When comparing receivers, it becomes clear that only the Denon AVR-X2500H has HDMI CEC. Like most receivers, our models have a built-in phono stage for connecting a vinyl player. There is an ECO mode in either AV receiver. The Denon AVR-X2500H can be properly configured using the setup assistant.
A Dolby Atmos multichannel audio format is available only in the AVR-X2500H. Only in the AVR-X2500H realized a DTS:X surround technology.
