What is better - Sony STR-DH770 vs Denon HEOS AVR?
The number of channels for receivers is different - 7.2 versus 5.1, respectively, for devices. In terms of power, there are differences, the STR-DH770 has such a ratio W/Ohm - 105/6, while the HEOS AVR has a power of 50/8, 65/6. The value of total harmonic distortion is also different, and for the STR-DH770 it is 0.09%, but for the HEOS AVR it is 0.05%. The Bi-amping function is implemented only in the Sony STR-DH770. Both Sony STR-DH770 and Denon HEOS AVR can transmit an audio signal directly to the amplifier and bypasses any DSP processing.
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.
Support for the HDR function can only boast of the STR-DH770. 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 STR-DH770 and the HEOS AVR. None of the devices can increase the resolution of the incoming video signal. Review participants do not have the Dolby Vision feature.
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 STR-DH770 and the HEOS AVR. When comparing receivers, it becomes clear that only the Denon HEOS AVR has HDMI CEC. STR-DH770 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.
Generally no support for a Dolby Atmos multichannel audio format. A DTS:X surround technology is not supported by devices from our comparison.
