Vizio M213ad-K8
Score: 86/100
Marshall Acton III Midnight Blue
Score: 77/100Rankings

The VIZIO M-Series M213ad-K8 delivers powerful 2.1 sound with dual subwoofers, strong bass, and a suite of immersive audio formats in a compact package. It shines with easy HDMI ARC setup and dialogue enhancement, but lacks HDMI eARC and true Dolby Atmos, making it less future-proof for high-end home-theater setups.

The midnight-blue Acton III offers the same 60 W RMS performance as its black counterpart, wrapped in a stylish, eco-friendly cabinet with tactile analog controls. It excels in Bluetooth convenience and sound quality for modest spaces, but lacks advanced codecs, Wi-Fi, and any form of portability.
