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

Amplifier

The number of channels for receivers is different - 5.1 versus 2.0, respectively, for devices. In terms of power, there are differences, the HEOS AVR has such a ratio W/Ohm - 50/8, 65/6, while the HK 3700 has a power of 85/8. The value of total harmonic distortion is also different, and for the HEOS AVR it is 0.05%, but for the HK 3700 it is 0.07%. None of the compared opponents supports Bi-amping. The model HEOS AVR can transmit an audio signal directly to the amplifier and bypasses any DSP processing. None of the AV receivers have an auto speaker calibration support.

None of the devices can increase the resolution of the incoming video signal. Review participants do not have the Dolby Vision feature. HDMI Audio Return Channel is only available on Denon HEOS AVR.
