17 Apr
Summary
- Denon Home 400 rivals Sonos Era 300 with Dolby Atmos.
- It supports native 24-bit/192kHz hi-res audio playback.
- Pricing varies significantly by region, impacting value.

Denon has introduced its second-generation home speaker lineup, including the Home 400, positioned as a direct rival to the Sonos Era 300. The Home 400 boasts a similar form factor and features up-firing Dolby Atmos speakers, all managed through Denon's HEOS multi-room audio platform. This platform supports numerous streaming services natively and integrates well with other HEOS-compatible devices.
The speaker is designed for versatile use, allowing for stereo pairing or integration as surround sound speakers with the Denon Home Sound Bar 550. For physical connectivity, it includes Wi-Fi, USB-C, and a 3.5mm aux input. Internally, the Home 400 features six drivers and dedicated Class D amplifiers for precise audio control. This acoustic setup represents a significant upgrade, enabling true Dolby Atmos music playback.
Audiophiles will appreciate the Home 400's native support for 24-bit/192kHz hi-res audio, a capability that exceeds the Sonos Era 300's input handling. While basic frequency controls are available, the app navigation can be less intuitive. The Denon Home 400 offers immersive sound and advanced features, positioning it as a strong contender in the sub-$500 market, though its competitive edge against Sonos varies by geographic region due to price differences.
