Having had an opportunity to test Yamaha RX-V675 vs Onkyo TX-NR616, I’d like to share my impression here to facilitate your choice of a new AV receiver.
AV receivers under review have the same number of channels. In terms of power, there are differences, the RX-V675 has such a ratio W/Ohm - 90/8, 150/4, while the TX-NR616 has a power of 160/6. The value of total harmonic distortion is also different, and for the RX-V675 it is 0.09%, but for the TX-NR616 it is 0.08%.
Competitive models use the same DAC. Each of the compared opponents supports Bi-amping. Both Yamaha RX-V675 and Onkyo TX-NR616 can transmit an audio signal directly to the amplifier and bypasses any DSP processing.
