A$165 is ambitious: it sits well above the A$105 75th-percentile asking price and nearly doubles the A$88 median from 28 comparable listings. With the condition marked unknown, this is not a bargain; it needs to be exceptionally clean, tested, and complete to justify the premium.
The ZP100 remains appealing for its straightforward 50W-per-channel amplification, Sonos multi-room integration, analogue inputs, subwoofer output, and ability to drive conventional passive speakers. It is a capable, compact streamer-amp for an S1-based system, but its age and S1-only operation limit the audience. At this money, insist on proof that both channels, network connection, line input, speaker terminals, and app control work properly; otherwise, a price nearer the A$66–A$105 range would be much more convincing.

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.
