Recent comparable listings put this model at a £46 median, with the lower quartile at £35 and upper quartile at £55. At £50, it is therefore a fair market price—above typical but still comfortably within the normal range, rather than an obvious bargain or an ambitious ask.
The ZP100 remains a likeable, compact 50-watt-per-channel amplifier with Sonos networking built in, useful analogue inputs and outputs, and enough drive for ordinary bookshelf or medium-sized standmount speakers. Its real appeal is the straightforward multi-room convenience alongside respectable, clean sound; it was a genuinely well-executed product in its day. At this price, insist on a demonstration of both channels, networking and analogue connections, and confirm that the seller includes the power lead.

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.
