What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 89/100
The Sonos Amp is widely praised for an open, spacious and engaging presentation with substantial bass, clear vocals and controlled treble. Its strengths lie in its punch, tonal warmth and unusually convincing stereo imaging, although What Hi-Fi? finds it less subtle and insightful than dedicated hi-fi separates at similar prices.
Transparency Resolution
87/100
Hi-Fi Choice hears an open sound, with multi-tracked harmonies remaining clear and distinct, while What Hi-Fi? notes decent detail behind leading edges. However, What Hi-Fi? also finds that it lacks the low-level dynamic delicacy, expressiveness and insight of stronger hi-fi-focused alternatives.
Tonal Balance Musicality
90/100
Hi-Fi Choice describes a well-balanced, attractive sound that works across musical styles, with rich and warm harmonies that retain separation. What Hi-Fi? similarly hears textured mids, substantial bass and glistening treble that avoids hardness, with an extra degree of vocal roundness available when Loudness is switched off.
Dynamics
87/100
Hi-Fi Choice finds the Amp taut, dramatic and precise, handling percussion and changes in pace with confidence. What Hi-Fi? also praises its punchy, upfront energy, but says fine dynamic shading and rhythmic flow fall short of the best similarly priced hi-fi components.
Soundstage Imaging
92/100
Both main listening reviews highlight spaciousness and precise placement. Hi-Fi Choice hears a relaxed, spacious stage with a clearly centred vocal and smoothly moving harmonies, while What Hi-Fi? praises the broad, deep presentation, focused effects placement and effective phantom-centre dialogue for TV use.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
88/100
What Hi-Fi? reports a densely packed internal layout and a fanless cooling system that draws air from underneath and exhausts it through the top. Gramophone calls the amplifier solid, noting its die-cast aluminium frame and sturdy banana terminals, while Alpha Audio appreciates the clean touch-control layout.
Features Connectivity
92/100
The Amp combines Sonos streaming and multiroom capability with Wi-Fi, dual Ethernet ports, AirPlay 2, analogue line input, subwoofer output and HDMI ARC/eARC for TV integration. App-based EQ, Trueplay support, HDMI control and a user-adjustable subwoofer crossover make it especially flexible for custom installs and two-channel TV systems, though it lacks hi-res playback support.
Value for Money
91/100
At roughly $699-$799, the Amp commands a meaningful premium over Sonos soundbars, but What Hi-Fi? considers the better TV performance and more hi-fi-like system potential persuasive. Gramophone is particularly enthusiastic, describing it as a knockout product with a strong feature set and sound quality that competes well with more expensive equipment.
