The number of channels for receivers is different - 7.1 versus 2.0, respectively, for devices. In terms of power, there are differences, the RX-V671 has such a ratio W/Ohm - 90/8, 150/4, while the HK 3700 has a power of 85/8. The value of total harmonic distortion is also different, and for the RX-V671 it is 0.09%, but for the HK 3700 it is 0.07%.

The manufacturer installed different DACs, the RX-V671 received the model Burr-Brown 192 KHz/24-bit, but the HK 3700 is equipped with 192 KHz/24-bit. The Bi-amping function is implemented only in the Yamaha RX-V671. The model RX-V671 can transmit an audio signal directly to the amplifier and bypasses any DSP processing.
