Denon AVR-X3700H vs Harman Kardon HK 3700 – that is a question.

Amplifier

The number of channels for receivers is different - 9.2 versus 2.0, respectively, for devices. In terms of power, there are differences, the AVR-X3700H has such a ratio W/Ohm - 105/8, 135/6, while the HK 3700 has a power of 85/8. The value of total harmonic distortion is also different, and for the AVR-X3700H it is 0.08%, but for the HK 3700 it is 0.07%. The Bi-amping function is implemented only in the Denon AVR-X3700H. The model 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 AVR-X3700H has access to the Spotify service. The number of available streaming services varies for receivers, the Denon AVR-X3700H works with Deezer, TIDAL, Pandora, SiriusXM, Qobuz, TuneIn Radio, but the Harman Kardon HK 3700 works with vTuner. HDMI signal transmission in standby mode can provide only the AVR-X3700H. Video scaling is only possible with the AVR-X3700H. Operation with the Dolby Vision is only possible with the AVR-X3700H. HDMI Audio Return Channel is only available on Denon AVR-X3700H. HDMI eARC is only supported by the AVR-X3700H. When comparing receivers, it becomes clear that only the Denon AVR-X3700H has HDMI CEC.
