Sony STR DH550

An affordable AV receiver is always a good option to consider, so Sony STR-DH590 vs Sony STR DH550 comparison definitely makes sense.

Audio features

Characteristics of digital to analog converter (DAC) are different, 192 KHz/32-bit for STR-DH590 and 192 KHz/24-bit for the STR DH550. None of the models support Bi-amping. The Sony STR-DH590 can transmit an audio signal directly to the amplifier and bypasses any DSP processing.

Unfortunately, HDMI eARC is not available on monitored devices. The Consumer Electronics Control (CEC) feature is present in most modern AV receivers and the models in our comparison are no exception. Both models support the standard HDCP 2.2. Receivers do not have a built-in phono stage for connecting a vinyl player. A voice control is not available. An ECO mode is not present in each of the AV receivers. Unfortunately, the setup assistant is not available in each of the models.
