What is better - Denon AVR-X1400H vs Denon AVR-S720W?
AV receivers under review have the same number of channels. In terms of power, there are differences, the AVR-X1400H has such a ratio W/Ohm - 80/8, 120/6, while the AVR-S720W has a power of 75/8, 110/6. A common feature for devices is the same total harmonic distortion - 0.08%.
The manufacturer installed different DACs, the AVR-X1400H received the model 192 KHz/24-bit, but the AVR-S720W is equipped with 192 KHz/32-bit. The Bi-amping function is implemented only in the Denon AVR-X1400H. Both Denon AVR-X1400H and Denon AVR-S720W 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-X1400H works with Deezer, TIDAL, Pandora, Napster, SiriusXM, TuneIn Radio, iHeart Radio, Sound Cloud, but the Denon AVR-S720W works with Pandora, SiriusXM.
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-X1400H and the AVR-S720W. None of the devices can increase the resolution of the incoming video signal. Operation with the Dolby Vision is only possible with the AVR-X1400H.
The number of HDMI inputs/outputs is the same - 6/1. HDMI Audio Return Channel is implemented in both devices. HDMI eARC is not supported by the AVR-X1400H and the AVR-S720W. When comparing receivers, it becomes clear that each of the rivals can work with HDMI CEC. AVR-X1400H and AVR-S720W support the standard HDCP 2.2. Unlike most receivers, our models do not have a built-in phono stage for connecting a vinyl player.
Unlike the AVR-X1400H where 3 Multi zones is provided, the AVR-S720W works with 2 Multi zones. There is an ECO mode in either AV receiver. The Denon AVR-X1400H and the Denon AVR-S720W can be properly configured using the setup assistant.
A Dolby Atmos multichannel audio format is available both models. A DTS:X surround technology is supported by devices from our comparison.
