This is a strong deal: US$100 sits exactly at the recent comparable listings’ 25th-percentile mark, well below the US$189 median and far under the US$305 75th percentile. For a tested-working Sonance Virtuoso A-800, that is bargain territory if the listing accurately reflects its condition.
The A-800 is a purpose-built subwoofer amplifier, making it a useful way to drive an in-wall or architectural subwoofer without spending on unnecessary full-range amplification. Sonance’s installation-oriented gear is valued for discreet system integration and dependable, dedicated bass power. At this price, the main practical check is whether the amplifier’s inputs, level controls, and protection behavior all function normally, and whether the included power cord or mounting hardware is present—but “tested working” makes this an attractive low-risk buy.
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.
