This is a serious multi-channel install amp, and the asking price looks fair rather than flashy. At US$235, it sits above the US$195 median but still well below the US$325 75th percentile, so it lands in the sensible part of the used market.
What makes it worthwhile is the practical value: lots of clean Class D channels in one chassis, bridgeable outputs, and a format that suits whole-home, patio, or distributed-audio setups better than cobbling together several smaller amps. If the unit is complete and powers up cleanly, this is the kind of purchase that can save space, wiring hassle, and money versus buying separate amplification.
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.
