vs

Having had an opportunity to test Denon AVR-X4000 vs Denon AVR-X3700H, I’d like to share my impression here to facilitate your choice of a new AV receiver.

Amplifier

The number of channels for receivers is different - 7.2 versus 9.2, respectively, for devices. In terms of power, there are differences, the AVR-X4000 has such a ratio W/Ohm - 125/8, 165/6, while the AVR-X3700H has a power of 105/8, 135/6. The value of total harmonic distortion is also different, and for the AVR-X4000 it is 0.05%, but for the AVR-X3700H it is 0.08%. Each of the compared opponents supports Bi-amping. Both Denon AVR-X4000 and Denon AVR-X3700H 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 versus AirPlay, AirPlay 2 respectively. Access to the Spotify service is on each of the competitors. The number of available streaming services varies for receivers, the Denon AVR-X4000 works with Pandora, Sirius XM, but the Denon AVR-X3700H works with Deezer, TIDAL, Pandora, SiriusXM, Qobuz, TuneIn Radio. Signaling over HDMI in standby mode can provide the AVR-X4000 and the AVR-X3700H. Each of the devices can increase the resolution of the incoming video signal. Operation with the Dolby Vision is only possible with the AVR-X3700H.

Extensive connections

The number of HDMI inputs/outputs is the same - 7/3. HDMI Audio Return Channel is implemented in both devices. HDMI eARC is only supported by the AVR-X3700H. When comparing receivers, it becomes clear that each of the rivals can work with HDMI CEC. The AVR-X4000 has support for the standard HDCP 2.2, compared to the AVR-X3700H, which supports the standard HDCP 2.3. Like most receivers, our models have a built-in phono stage for connecting a vinyl player.

Additional features

Unlike the AVR-X4000 where 3 Multi zones is provided, the AVR-X3700H works with 2 Multi zones. There is an ECO mode in AVR-X3700H. The Denon AVR-X4000 and the Denon AVR-X3700H can be properly configured using the setup assistant.

Multichannel surround

A Dolby Atmos multichannel audio format is available only in the AVR-X3700H. Only in the AVR-X3700H realized a DTS:X surround technology.
