New, the Connect:Amp sold for about USD 499, though it is now discontinued and superseded by the more powerful Sonos Amp. At USD 155, this used example sits comfortably above the USD 111 median but below the USD 200 75th percentile from 251 comparable listings: fair market money, not a bargain, but certainly not excessive.
Its appeal is straightforward: a compact 2×55-watt Class-D amplifier that turns ordinary passive speakers into a convenient Sonos zone, with useful analogue inputs, Ethernet, and dependable multi-room operation. The main qualification is its legacy status, so confirm that it works with the intended Sonos setup before buying. At this price, clean operation, the original power cord, and a straightforward return option would make it a sensible purchase; without those assurances, negotiating modestly lower would be reasonable.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
