Denon HEOS AVR vs Onkyo TX-SR494 review

vs

Denon HEOS AVR vs Onkyo TX-SR494 – that is a question.

Amplifier

The number of channels for receivers is different - 5.1 versus 7.2, respectively, for devices. In terms of power, there are differences, the HEOS AVR has such a ratio W/Ohm - 50/8, 65/6, while the TX-SR494 has a power of 135/6. The value of total harmonic distortion is also different, and for the HEOS AVR it is 0.05%, but for the TX-SR494 it is 0.08%. The Bi-amping function is implemented only in the Onkyo TX-SR494. Both Denon HEOS AVR and Onkyo TX-SR494 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 HEOS AVR and the TX-SR494. None of the devices can increase the resolution of the incoming video signal. Review participants do not have the Dolby Vision feature.

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 HEOS AVR and the TX-SR494. When comparing receivers, it becomes clear that each of the rivals can work with HDMI CEC. HEOS AVR and TX-SR494 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. The Onkyo TX-SR494 can be properly configured using the setup assistant.

Multichannel surround

A Dolby Atmos multichannel audio format is available only in the TX-SR494. Only in the TX-SR494 realized a DTS:X surround technology.
