£183 is a fair ask, sitting above the £132 median but still well below the £257 upper quartile for recent comparable GBP listings. It’s not a bargain-bin price, but it’s comfortably in sensible used-market territory for a serious rack-mount DSP power amp.
What makes it worthwhile is the format: these Sonance install amps are built for dependable, clean power and flexible DSP control, which suits multi-room, cinema, or custom-install duties very well. If it’s complete, undamaged, and powers up cleanly, this is the kind of piece that can be a very practical buy rather than a flashy one; just make sure any setup software, wiring adapters, or rack ears you need 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.
