The number of channels for receivers is different - 5.1 versus 7.2, respectively, for devices. In terms of power, there are differences, the RX-V385 has such a ratio W/Ohm - 70/6, while the AVR-X2500H has a power of 95/8, 125/6. The value of total harmonic distortion is also different, and for the RX-V385 it is 0.09%, but for the AVR-X2500H it is 0.08%.
The manufacturer installed different DACs, the RX-V385 received the model Burr-Brown 384 KHz/32-bit, but the AVR-X2500H is equipped with AK4490 384 KHz/32-bit. The Bi-amping function is implemented only in the Denon AVR-X2500H. Both Yamaha RX-V385 and Denon AVR-X2500H can transmit an audio signal directly to the amplifier and bypasses any DSP processing.
