The typical used asking price is US$196, with the middle half running from US$100 to US$320. At US$325, this sits just above the 75th-percentile ceiling, so it’s ambitious rather than a bargain; it needs excellent condition, a complete package, or unusually strong proof of operation to make sense.
The appeal is real: this is a flexible 12-channel installation amplifier, delivering 50 watts per channel with all channels driven, offering bus and loop connections, independent level controls, triggers, and bridgeable pairs for 100 watts. Its efficient Class D design is well suited to whole-home audio and multiroom systems. Confirm that every channel works quietly, that both bridged modes and controls behave properly, and that the unit matches the buyer’s mains voltage. At this price, a warranty or thorough test report would materially improve the proposition.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Sonance is an American architectural audio brand founded in the early 1980s by Scott Struthers and Geoff Spencer in Southern California. The company emerged from a simple but powerful idea: that high‑fidelity sound should not compromise interior design. In 1982, Sonance introduced the world’s first in‑wall loudspeaker, effectively creating the architectural speaker category and establishing a legacy built on innovation and discretion.
Today, Sonance is best known for in‑wall and in‑ceiling loudspeakers, outdoor audio systems, and multi‑room audio solutions, rather than amplifiers, turntables, DACs, or headphones. Its product range includes residential and commercial speakers, volume controls, and related electronics designed to blend seamlessly into walls, ceilings, and outdoor environments. The brand’s “degrees of invisibility” philosophy emphasizes clean aesthetics, flexible installation, and consistent performance across diverse spaces, from luxury homes to commercial venues.
Sonance occupies a strong position in the mid‑to‑high‑end custom‑installation market, widely recognized and frequently awarded in architectural and outdoor audio. It is a go‑to choice for integrators, architects, and design‑conscious clients who prioritize both performance and visual subtlety, rather than visible hi‑fi hardware.
