New, this model sat far above the typical used market, but at US$575 it also lands well above the recent used median of US$199 and the 75th percentile of US$385, so this is an ambitious ask rather than a bargain. It needs to justify itself on condition, provenance, and convenience, because the price is in premium-used territory.
That said, the Amp is a genuinely capable little workhorse: clean Class D power, easy streaming integration, and enough output to run a serious stereo or compact 2.1 setup without fuss. The included power cord and free shipping are small positives, but at this level the buyer should want a spotless unit, solid cosmetics, and confidence it’s been used gently and tested well.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Sonos emerged from Santa Barbara, California, in 2002 as Rincon Audio, Inc., founded by John MacFarlane, Craig Shelburne, Tom Cullen, and Trung Mai. MacFarlane's success with Software.com provided crucial seed funding for their audacious goal: a wireless multi-room music system free from the wires and complexity plaguing home audio at the time. Renamed Sonos in 2004, the company debuted its pioneering ZonePlayer and controller in 2005, cementing its roots in innovative, user-centric sound technology.
The brand specializes in wireless speakers, soundbars, and home theater systems designed for seamless multi-room playback and integration with streaming services. Sonos offers everything from portable Bluetooth options like the Roam to high-fidelity architectural speakers and subwoofers, alongside recent forays into headphones and whole-home audio solutions. Amplifiers, turntables, DACs, and cables fall outside their core focus, which prioritizes app-controlled ecosystems over traditional hi-fi components.
Sonos holds a commanding mid-to-premium position in the consumer audio market, renowned for inventing wireless HiFi and setting the standard for effortless, high-quality sound. Trusted by audiophiles and casual listeners alike, it blends accessibility with sonic excellence, dominating the smart speaker segment while appealing to discerning buyers seeking scalable, future-proof systems.
