Key Takeaways
- • Naim has launched the Mu-so Utopia, an all-in-one speaker positioned as the true sequel to its legacy Mu-so line, priced at £4499 / €5000 / $5500, up from £2999 for the Focal-developed Mu-so Hekla.
- • The Mu-so Utopia raises total system power to 720W from the Hekla's 660W, and extends room coverage to 50m² from 40m², according to Trusted Reviews.
- • Naim claims distortion is reduced by about five times compared with the Hekla, driven by over-specified midrange amplifiers and a combination of Class D and Class A/B amplification.
- • Every drive unit is new versus the Hekla, including Focal-derived PRISM tweeters and a pair of M-shaped midrange drivers, with the focus on two-channel music rather than immersive AV.
- • Core specifications, including the 15-driver layout, built-in subwoofer and cabinet size, are largely unchanged, with streaming support spanning Google Cast, Spotify Connect, Qobuz Connect, AirPlay 2, Tidal Connect and Bluetooth.
Summary
Naim has unveiled the Mu-so Utopia, a new all-in-one wireless speaker that Trusted Reviews describes as the successor to the legacy Mu-so line and the first Naim Mu-so product to carry the Utopia name, previously used for Focal's large active loudspeakers. The product was developed alongside Focal's five-star Mu-so Hekla, and while the two share a similar form factor, the Utopia is positioned by Naim as a two-channel and music-focused product rather than an immersive AV system.
The Utopia's principal hardware changes center on drivers and amplification. All drive units are new relative to the Hekla, including Focal-derived PRISM tweeters and a pair of midrange M-shaped drivers. The speaker retains upward-firing drivers for Dolby Atmos support, but Naim has said that for two-channel music it can bypass Dolby's processing to shorten the signal path and further reduce distortion and colouration. The amplification combines Class D and Class A/B stages, with Class A/B offering greater control over the highs. Total output rises from 660W on the Hekla to 720W, supported by a new power supply. During a tour of Naim's Salisbury headquarters, Trusted Reviews was told that the midrange amplifiers are "incredibly over specc'd", allowing them to be underdriven at very low distortion, which Naim says cuts distortion by about five times relative to the Hekla.
Despite these upgrades, the physical design is largely unchanged. The cabinet remains the same size, includes a built-in subwoofer, and adds a red trim accent. Connectivity includes Google Cast, Spotify Connect, Qobuz Connect, AirPlay 2, Bluetooth, Tidal Connect and Presto Music, along with an HDMI eARC port for TV connection. Audio support extends to 32-bit/384kHz WAV, DSD64 and DSD128, while Bluetooth remains limited to SBC and AAC codecs.
The price increase is significant. The Utopia lists at £4499, €5000 or $5500, compared with £2999 for the Hekla, reflecting the new driver set and amplification. Trusted Reviews notes the speaker's room coverage rises to 50m² from 40m². The publication's reporting is based on a pre-release briefing and presentation, and the Utopia's performance has not yet been independently assessed in the source material.
