Score: 78/100
Polk Audio Signa S4
Score: 73/100Rankings

The Sony STR-DH590 is a solid 5.2-channel AV receiver delivering strong power, 4K HDR support, and Bluetooth streaming in a compact package. It lacks immersive object-based audio formats and advanced smart-home features, making it best suited for straightforward 5.1 setups.

The Signa S4 is a low-profile 3.1.2-channel soundbar with a wireless subwoofer that brings Dolby Atmos immersion and clear dialogue to midsize rooms, while keeping setup simple and cost-effective.
