Unknown condition makes the price slightly harder to judge, but US$192 is a fair ask and very close to the US$187 median from 250 comparable listings. It is well below the US$300 75th-percentile mark, though not the bargain territory below US$100; value will depend mainly on confirmed operation and cosmetic condition.
The 275 SE is a capable, high-current two-channel amplifier: roughly 75 watts per channel into 8 ohms, with substantial low-impedance drive and the option to bridge for about 250 watts. Its factory BBE module can add presence and detail at modest listening levels, particularly with in-wall, in-ceiling, or background-music systems, though many purist setups will prefer it bypassed. At this price, verify both channels, the BBE controls, trigger, binding posts, and any hum or relay issues before buying.
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.
