This looks like a fair ask, slightly on the sensible side for the market: US$150 sits above the US$109 25th percentile but below the US$180 median, so it’s not a bargain-bin score, yet it is still priced under the typical middle of recent comps. For a Sonance DSP amp, that makes it reasonable if the unit is genuinely working and the seller can show clean test results.
What gives it appeal is the Sonance name and the fact that these DSP multi-channel amps can be very useful in custom installs, with enough power and processing to anchor a neat whole-house or theater setup. The only real caution here is the “tested for parts” wording, which is a material risk on a power amp; at this price, a buyer should want clarity on what actually works, whether all channels pass audio, and whether any accessories or rack ears are included.
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.
