The number of channels for receivers is different - 5.2 versus 5.1, respectively, for devices. In terms of power, there are differences, the AVR-S510BT has such a ratio W/Ohm - 75/8, 110/6, while the VSX-531 has a power of 80/8, 140/6. A common feature for devices is the same total harmonic distortion - 0.08%.
The manufacturer installed different DACs, the AVR-S510BT received the model 192 KHz/32-bit, but the VSX-531 is equipped with 192 KHz/24-bit. None of the compared opponents supports Bi-amping. The model VSX-531 can transmit an audio signal directly to the amplifier and bypasses any DSP processing.
