What is better - Onkyo TX-SR393 vs Denon HEOS AVR?

Amplifier

The number of channels for receivers is different - 5.2 versus 5.1, respectively, for devices. In terms of power, there are differences, the TX-SR393 has such a ratio W/Ohm - 80/8, 155/6, while the HEOS AVR has a power of 50/8, 65/6. The value of total harmonic distortion is also different, and for the TX-SR393 it is 0.08%, but for the HEOS AVR it is 0.05%. None of the compared opponents supports Bi-amping. The model HEOS AVR can transmit an audio signal directly to the amplifier and bypasses any DSP processing.

Connectivity

Wireless Internet connection via WIFI is only possible with HEOS AVR. Each of the receivers has a Bluetooth connector. Support for Apple Music Services not implemented. The HEOS AVR has access to the Spotify service. 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 TX-SR393 and the HEOS AVR. Video scaling is only possible with the TX-SR393. Operation with the Dolby Vision is only possible with the TX-SR393.

Extensive connections

The number of HDMI inputs/outputs is the same - 4/1. HDMI Audio Return Channel is implemented in both devices. HDMI eARC is not supported by the TX-SR393 and the HEOS AVR. When comparing receivers, it becomes clear that each of the rivals can work with HDMI CEC. TX-SR393 and HEOS AVR support the standard HDCP 2.2. Unlike most receivers, our models do not have a built-in phono stage for connecting a vinyl player. There is an ECO mode in neither AV receiver. None of these units can be properly configured using the setup assistant.

Multichannel surround

A Dolby Atmos multichannel audio format is available only in the TX-SR393. Only in the TX-SR393 realized a DTS:X surround technology.
