The ZP100 is a respected early Sonos amp: simple, sturdy, and still appealing if you want dependable multi-room streaming with proper speaker outputs. At £53, this sits a touch above the £42 median and just under the £55 75th percentile, so it reads as fair rather than a bargain or an ambitious ask.
What makes it worthwhile is the combination of Sonos ease and amp functionality in one box, especially if you already like the Sonos ecosystem and want a compact used entry point. At this price, the main check is practical rather than worrying: make sure it powers up cleanly, joins the system properly, and includes the essentials, because a good, complete unit here is still a sensible buy.

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.
