This is a fair ask, leaning a touch above the typical used market but not out of line. At US$300, it sits above the US$190 median and below the US$326 75th percentile from recent comparable listings, so it reads as a reasonable price rather than a bargain or an overreach.
What makes it appealing is the DSP power amp angle: these are valued for solid installed-audio performance, useful onboard processing, and enough output to do real work without fuss. The included cable is a small but real bonus, and if it’s clean, fully functional, and hasn’t been heavily abused in a rack, this is the kind of practical amp that can be a very good buy for a system that needs flexible power and tuning.
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.
