The latest Sonos Amp Multi arrives as the company steps back onto the hardware stage, aiming squarely at the niche of high-end installations. After a period of deliberate quiet, Sonos turned its focus inward, smoothing out a mobile app that had become a source of frustration and mending a brand image bruised by a widely panned software revamp. Observers note that the new amplifier, with its robust digital heart, signals a renewed confidence in the company's core audio expertise. By pairing fresh gear with a steadier software experience, Sonos appears intent on restoring the trust that once made its living-room sound systems a household name.
