vs

Having had an opportunity to test Sony STR-DH770 vs Yamaha RX-S602, I’d like to share my impression here to facilitate your choice of a new AV receiver.

Amplifier

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 RX-S602 has a power of 80/8, 125/6. The value of total harmonic distortion is also different, and for the STR-DH770 it is 0.09%, but for the RX-S602 it is 0.08%.

Audio features

The manufacturer installed different DACs, the STR-DH770 received the model 192 KHz/24-bit, but the RX-S602 is equipped with Burr-Brown 384 KHz/32-bit. Each of the compared opponents supports Bi-amping. Both Sony STR-DH770 and Yamaha RX-S602 can transmit an audio signal directly to the amplifier and bypasses any DSP processing. Each of the receivers has a Bluetooth connector. The RX-S602 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 STR-DH770 and the RX-S602. 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 STR-DH770 and the RX-S602. When comparing receivers, it becomes clear that only the Yamaha RX-S602 has HDMI CEC. The STR-DH770 has support for the standard HDCP 2.2, compared to the RX-S602, which supports the standard HDCP 2.3. Unlike most receivers, our models do not have a built-in phono stage for connecting a vinyl player.
