The Sonamp 260×3 has a solid reputation as a capable multi-zone power amplifier, and A$120 is a genuine bargain: it sits below the A$143 25th-percentile mark from 252 comparable listings, versus a A$268 median and A$431 75th percentile. Even allowing for its age, that is very attractive money for a working example.
Its appeal is practical rather than boutique: 60 watts per channel, three-channel operation, auto-on and looping connections, and unusually comfortable handling of low-impedance speaker loads make it well suited to distributed audio or several pairs of speakers. At this price, the unknown condition is the only real variable—confirm all channels, outputs, controls and RCA connections work, and check for excessive hum or heat. If it passes a basic test, this is an easy buy for a secondary-zone system.
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.
