Having had an opportunity to test Denon AVR-X4500H vs Pioneer SC-LX501, I’d like to share my impression here to facilitate your choice of a new AV receiver.
The number of channels for receivers is different - 9.2 versus 7.2, respectively, for devices. In terms of power, there are differences, the AVR-X4500H has such a ratio W/Ohm - 125/8 20Hz-20KHz, 165/6 1KHz, while the SC-LX501 has a power of 120/8 20Hz-20KHz, 180/6 1KHz. The value of total harmonic distortion is also different, and for the AVR-X4500H it is 0.05%, but for the SC-LX501 it is 0.08%.
Competitive models use the same DAC. Each of the compared opponents supports Bi-amping. Both Denon AVR-X4500H and Pioneer SC-LX501 can transmit an audio signal directly to the amplifier and bypasses any DSP processing. Each of the receivers has a Bluetooth connector. The contenders have differences in the supported services from Apple - AirPlay, AirPlay 2 versus AirPlay respectively. Access to the Spotify service is on each of the competitors.
