Denon AVR-X540BT vs Onkyo TX-SR383 – that is a question.
The number of channels for receivers is different - 5.2 versus 7.2, respectively, for devices. In terms of power, there are differences, the AVR-X540BT has such a ratio W/Ohm - 70/8, 90/6, while the TX-SR383 has a power of 100/8, 135/6. The value of total harmonic distortion is also different, and for the AVR-X540BT it is 0.08%, but for the TX-SR383 it is 0.09%.
Competitive models use the same DAC. None of the compared opponents supports Bi-amping. The model AVR-X540BT can transmit an audio signal directly to the amplifier and bypasses any DSP processing.
Wireless connection to the Internet via WIFI can not be performed on these receivers. Each of the receivers has a Bluetooth connector. Support for Apple Music Services not implemented. The AVR-X540BT has access to the Spotify service.
Support for the HDR function can only boast of each of the AV receivers. The quality of 4K/60Hz signal remains unchanged when transmitting from a source to a TV or projector via HDMI for both receivers. Signaling over HDMI in standby mode can provide the AVR-X540BT and the TX-SR383. None of the devices can increase the resolution of the incoming video signal. Operation with the Dolby Vision is only possible with the AVR-X540BT.
The number of HDMI inputs/outputs varies depending on the receiver, the AVR-X540BT has 5/1, and the TX-SR383 has 4/1. HDMI Audio Return Channel is implemented in both devices. HDMI eARC is not supported by the AVR-X540BT and the TX-SR383. When comparing receivers, it becomes clear that each of the rivals can work with HDMI CEC. AVR-X540BT and TX-SR383 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 AVR-X540BT. The Denon AVR-X540BT can be properly configured using the setup assistant.
Generally no support for a Dolby Atmos multichannel audio format. A DTS:X surround technology is not supported by devices from our comparison.
