Denon AVR-S540BT vs Sony STR-DN1050 – that is a question.
The number of channels for receivers is different - 5.2 versus 7.2, respectively, for devices. In terms of power, there are differences, the AVR-S540BT has such a ratio W/Ohm - 70/8, 90/6, while the STR-DN1050 has a power of 120/6. The value of total harmonic distortion is also different, and for the AVR-S540BT it is 0.08%, but for the STR-DN1050 it is 0.09%.
The manufacturer installed different DACs, the AVR-S540BT received the model 192 KHz/32-bit, but the STR-DN1050 is equipped with 96 KHz/24-bit. The Bi-amping function is implemented only in the Sony STR-DN1050. The model STR-DN1050 can transmit an audio signal directly to the amplifier and bypasses any DSP processing.
