What is better - Pioneer VSX-531 vs Denon AVR-S720W?
The number of channels for receivers is different - 5.1 versus 7.2, respectively, for devices. In terms of power, there are differences, the VSX-531 has such a ratio W/Ohm - 80/8, 140/6, while the AVR-S720W has a power of 75/8, 110/6. A common feature for devices is the same total harmonic distortion - 0.08%.
The manufacturer installed different DACs, the VSX-531 received the model 192 KHz/24-bit, but the AVR-S720W is equipped with 192 KHz/32-bit. None of the compared opponents supports Bi-amping. Both Pioneer VSX-531 and Denon AVR-S720W can transmit an audio signal directly to the amplifier and bypasses any DSP processing.
Wireless Internet connection via WIFI is only possible with AVR-S720W. Each of the receivers has a Bluetooth connector. The AVR-S720W has access to the Spotify service.

Review participants do not have the Dolby Vision feature.
The number of HDMI inputs/outputs varies depending on the receiver, the VSX-531 has 4/1, and the AVR-S720W has 6/1. HDMI Audio Return Channel is implemented in both devices. HDMI eARC is not supported by the VSX-531 and the AVR-S720W. When comparing receivers, it becomes clear that each of the rivals can work with HDMI CEC. VSX-531 and AVR-S720W support the standard HDCP 2.2. Unlike most receivers, our models do not have a built-in phono stage for connecting a vinyl player. Voice control of the basic functions of the receiver is not realized in both models. There is an ECO mode in either AV receiver.
