Denon AVR-X2400H vs Onkyo TX-NR545 review

vs
Onkyo TX-NR545

Having had an opportunity to test Denon AVR-X2400H vs Onkyo TX-NR545, I’d like to share my impression here to facilitate your choice of a new AV receiver.

Amplifier

AV receivers under review have the same number of channels. In terms of power, there are differences, the AVR-X2400H has such a ratio W/Ohm - 95/8, 125/6, while the TX-NR545 has a power of 100/6. A common feature for devices is the same total harmonic distortion - 0.08%.

Audio features

The manufacturer installed different DACs, the AVR-X2400H received the model 192 KHz/24-bit, but the TX-NR545 is equipped with Hi-Grade 384 KHz/32-bit. The Bi-amping function is implemented only in the Onkyo TX-NR545. Both Denon AVR-X2400H and Onkyo TX-NR545 can transmit an audio signal directly to the amplifier and bypasses any DSP processing. 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-X2400H works with Deezer, TIDAL, iHeart Radio, Sirius XM, Sound Cloud, Napster, but the Onkyo TX-NR545 works with Tunein Radio.

Video features

Support for the HDR function can only boast of each of the AV receivers. The quality of 4K/60Hz signal remains unchanged when transmitting from a source to a TV or projector via HDMI for both receivers. Signaling over HDMI in standby mode can provide the AVR-X2400H and the TX-NR545. None of the devices can increase the resolution of the incoming video signal. Operation with the Dolby Vision is only possible with the AVR-X2400H.

Extensive connections

The number of HDMI inputs/outputs varies depending on the receiver, the AVR-X2400H has 8/2, and the TX-NR545 has 6/1.Denon AVR-X2400H connectionsOnkyo TX-NR545 connections HDMI Audio Return Channel is implemented in both devices. HDMI eARC is not supported by the AVR-X2400H and the TX-NR545. When comparing receivers, it becomes clear that each of the rivals can work with HDMI CEC. AVR-X2400H and TX-NR545 support the standard HDCP 2.2. Unlike most receivers, our models do not have a built-in phono stage for connecting a vinyl player.

Additional features

Ability to create 2 Multi zones inherent in both AV receivers. There is an ECO mode in AVR-X2400H. The Denon AVR-X2400H and the Onkyo TX-NR545 can be properly configured using the setup assistant.

Multichannel surround

A Dolby Atmos multichannel audio format is available both models. Only in the AVR-X2400H realized a DTS:X surround technology.
