New, the 4B SST sold around US$3,000–US$4,195 depending on version and period. At US$3,400, this used example is clearly above your comparable market’s US$3,100 75th percentile and is therefore ambitious rather than a bargain; the US$3,000 median is the more convincing target.
That said, the 4B SST remains a serious, highly capable amplifier: its dual-mono design delivers roughly 300 watts per channel into 8 ohms and 500 into 4 ohms, with the current and control to handle difficult speakers. Bryston’s reputation for rugged construction, low noise, reliability, and long warranty support is deserved. At this price, insist on excellent cosmetic and electrical condition, documented service or original-owner history, and complete balanced/single-ended input options; otherwise, negotiate toward US$3,000 or below.

Bryston emerged from Canada's medical electronics sector, where it began producing high-tech blood analyzers in 1962. The pivot to high-performance audio came in 1976, sparked by James Tanner's quest to drive demanding electrostatic speakers. Drawing on medical-grade components, the debut of the 4B amplifier at the Chicago Consumer Electronics Show marked the brand's entry into hi-fi, quickly earning acclaim from critics like Peter Aczel and establishing its Canadian manufacturing legacy.
Renowned for robust amplifiers and preamplifiers, Bryston has expanded into digital components such as DACs and streamers, as well as powered speakers. This evolution reflects a commitment to both analog purity and modern digital demands, serving consumer, professional, and commercial markets—from home listening to stadium sound reinforcement—while maintaining a focus on uncompromised musical accuracy.
Positioned firmly in the high-end audio arena, Bryston commands respect for its no-nonsense engineering, timeless designs, and unparalleled reliability, backed by industry-leading warranties. Music and movie enthusiasts trust it for scientifically verifiable sound quality that endures for decades, cementing its status as a benchmark for discerning buyers seeking longevity without compromise.
