It’s strongly recommended to compare different receivers if you want to choose the best one: Denon AVR-X540BT vs Marantz NR1506.
AV receivers under review have the same number of channels. In terms of power, there are differences, the AVR-X540BT has such a ratio W/Ohm - 70/8, 90/6, while the NR1506 has a power of 50/8, 60/6. The value of total harmonic distortion is also different, and for the AVR-X540BT it is 0.08%, but for the NR1506 it is 0.05%.
Competitive models use the same DAC. None of the compared opponents supports Bi-amping. Both Denon AVR-X540BT and Marantz NR1506 can transmit an audio signal directly to the amplifier and bypasses any DSP processing.
