A:Answer made a similar move and I’d call it a trade-off rather than a straight upgrade or downgrade. The Sonos Five surrounds deliver huge, powerful rear-channel sound and excellent music performance with a lot of punch and volume. The Era 300s, however, completely change the surround experience with Dolby Atmos and much more immersive spatial effects.
For movies and Atmos content with an Arc, I personally think the Era 300s are the better home theater setup. The sound bubble feels larger and more three-dimensional. For pure loudness and music-heavy listening, the Fives still hit harder. If you watch a lot of movies and stream Atmos content, I think the Era 300s are worth it.
