Against the recent used market, this asking price is ambitious: US$717 sits well above the 75th percentile of US$326 and far above the US$180 median, so it’s not a casual grab unless this exact piece is unusually well documented or upgraded. For a buyer, that means the listing needs to justify itself on condition, provenance, and completeness rather than price alone.
The appeal here is straightforward: Sonance DSP power amps are built for serious multi-room or custom-install duty, with clean digital signal processing and plenty of channel control for a tidy system integration. If it’s truly clean, fully functional, and comes with the right accessories or install history, there is real utility value—but at this level, I’d want strong proof of serviceability and a clear reason it commands a premium over typical used examples.
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.
