Sonos Beam Gen 2 White
Score: 67/100
Marshall Acton III Midnight Blue
Score: 77/100Rankings

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.

The Sonos Beam (Gen 2) is a compact soundbar offering Dolby Atmos and integrated voice assistants, delivering immersive audio for small to medium rooms while fitting seamlessly into the Sonos ecosystem. Its lack of DTS support, thin bass, and reliance on HDMI eARC for Atmos are its main drawbacks.
