Sony STR-DH790 vs Denon AVR-S540BT – that is a question.
The number of channels for receivers is different - 7.2 versus 5.2, respectively, for devices. In terms of power, there are differences, the STR-DH790 has such a ratio W/Ohm - 90/6, while the AVR-S540BT has a power of 70/8, 90/6. The value of total harmonic distortion is also different, and for the STR-DH790 it is 0.09%, but for the AVR-S540BT it is 0.08%.
The manufacturer installed different DACs, the STR-DH790 received the model 192 KHz/24-bit, but the AVR-S540BT is equipped with 192 KHz/32-bit. The Bi-amping function is implemented only in the Sony STR-DH790. The model STR-DH790 can transmit an audio signal directly to the amplifier and bypasses any DSP processing.
