Denon AVR-X2500H vs Harman Kardon HK 3700 – that is a question.

Amplifier

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 HK 3700 has a power of 85/8. The value of total harmonic distortion is also different, and for the AVR-X2500H it is 0.08%, but for the HK 3700 it is 0.07%.

Audio features

The manufacturer installed different DACs, the AVR-X2500H received the model AK4490 384 KHz/32-bit, but the HK 3700 is equipped with 192 KHz/24-bit. The Bi-amping function is implemented only in the Denon AVR-X2500H. The model AVR-X2500H can transmit an audio signal directly to the amplifier and bypasses any DSP processing.

Connectivity

Wireless Internet connection via WIFI is only possible with AVR-X2500H. Each of the receivers has a Bluetooth connector. The AVR-X2500H has access to the Spotify service. 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 Harman Kardon HK 3700 works with vTuner. 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 HK 3700. 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 AVR-X2500H. The Denon AVR-X2500H can be properly configured using the setup assistant.
