This US$133 asking price is a strong deal, sitting well below the 25th percentile of US$119 for recent comparable Sonance SONAMP 1230 listings, and far under the median of US$156. While the unit has been replaced by newer matrix amps, the SONAMP 1230 remains a respected 12-channel, 30WPC pro power amp that delivers reliable performance for multi-room or commercial installations, especially when driving 8-ohm speakers in bridge mode.
The real upside here is the price-to-performance ratio: at US$133, you’re getting a robust, well-regarded pro amplifier for less than most buyers pay for a single channel of a modern consumer amp. Unless the listing flags missing rails, failed capacitors, or a broken trigger bypass (a known quirk), this is a clean buying opportunity for an enthusiast who values raw channel count and durability over brand prestige.
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.
