Compared with buying a conventional two-channel power amp at US$650, this is a specialized multi-room proposition rather than an obvious bargain. The asking price is ambitious: recent comparable listings have a median of US$199, with the 75th percentile at US$319, putting US$650 well beyond the normal used-market range. Unless this is a particularly clean, complete, and current-version example, substantial negotiation is warranted.
Its appeal is genuine for an installation: eight channels deliver 130 watts per channel into 8 ohms, with DSP presets, per-channel EQ, IP control, four stereo zones, and bridged operation for up to 300 watts. That flexibility can replace several boxes and is especially useful with architectural speakers. Before paying premium money, confirm the exact MKII/MKIII version, working Ethernet and DSP control, included input modules, rack hardware, and stable operation under load; at this price, completeness and a convincing test matter.
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.
