US$579 is fair to slightly firm against your comp set: it sits just above the 75th percentile at US$579, with the median at US$499 and the 25th percentile at US$399. That makes it more “top of market” than bargain territory, but not out of line if the unit is genuinely clean and complete.
For a Sonance DSP 8-130 MKII, the appeal is the Sonance install-grade build and onboard DSP, which can make integration and tuning much easier than a plain amp if you’re pairing it with custom or distributed audio. The upside here is mainly convenience and system flexibility, so I’d want confidence on condition, channel functionality, and included accessories at this price; if it’s fully checked out and well kept, it’s a reasonable buy, but not a steal.
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.
