At USD 75, this is a strong deal: it sits below the USD 100 25th-percentile mark and well under the USD 193 median from 242 recent comparable listings. Assuming the test result is accurate, the asking price leaves plenty of room for a worthwhile purchase.
The A800 is a purpose-built mono subwoofer amplifier, making it a sensible choice for driving a passive home-theater or music subwoofer with more authority than a typical receiver channel. Its dedicated design and Sonance’s solid reputation are the main appeal, while the tested status reduces the biggest buying uncertainty. Before paying, confirm that the gain, inputs, speaker output, and power switch all work properly under load, but at USD 75 this is plainly a bargain rather than a marginal value.
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.
