Compared with a new Sonos Amp, this is the legacy-value play: at US$65, it lands just above the US$61 median and well inside the normal used band, so it reads as fair rather than cheap or ambitious. It’s not a steal, but it’s close enough to market that a clean unit can make sense if you want this older Sonos ecosystem piece.
The appeal is straightforward: the ZP100 is a well-built, self-contained streamer/amp that still suits a simple whole-house or garage setup, and it was the original Sonos way to add powered zones without extra boxes. The real upside is convenience and compatibility with legacy Sonos use cases; just make sure it includes the power lead and that it boots, joins the network, and outputs cleanly, since age-related faults are the only meaningful concern here.

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.
