This is a buyer’s market for vintage Sonance sub amps, and the US$210 asking price is fair, sitting just above the US$180 median from 103 recent comparable listings while well below the US$350 75th percentile [ground truth]. It’s not a bargain, but it’s a solid, honest price for a tested-working unit in this category.
The Sonance Virtuoso A-800 is a respected 1-channel, 90-watt RMS Class D subwoofer amplifier loved for its clean, tight low-end and compact rack-friendly design, often used to drive in-wall or in-ceiling subs in high-end home theaters. At US$210, you’re getting a reliable, original Sonance “Sonamp” that still delivers serious performance, especially if it includes the original IEC power cord and manual. No red flags here—this is a straightforward buying opportunity for a fellow enthusiast who values Sonance’s legacy in discreet, high-fidelity audio.

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.
