A strong deal at £34, sitting below the £32–£54 middle-market band only marginally but still well under the £41 median for comparable used units. It is comfortably toward the bargain end, assuming it is working and complete.
The ZP100 remains a useful little network amplifier: its 50 watts per channel, analogue input/output, subwoofer output and Ethernet switching make it unusually versatile for a compact second-system or workshop setup. It is best suited to someone already using Sonos S1, since this older generation is tied to that ecosystem rather than current Sonos platforms. At £34, that limitation is easy to accept; check that it powers up, joins the S1 app and includes a mains lead before buying.

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.
