Nice shape and sounds amazing! Some cosmetic shortcomings as seen in the photos. The big gash on the bottom was literally when I had it on the bench taking these pics. 🤦🏻♂️
Should you consider $799 USD a bargain for this used Bryston 4B? Yes, because typical used pricing for the Bryston 4B-ST sits around $1100 USD, making $799 USD a clear bargain well below the 25th percentile. This price is significantly lower than the median, so it represents an excellent buying opportunity for a fellow enthusiast who values proven performance over brand-new gear.
The Bryston 4B is well-regarded for its robust Class A/B design, delivering 250W into 8 ohms and 400W into 4 ohms, with the ability to bridge for 800W mono. Its low distortion (≤0.005%) and 20-year warranty pedigree make it a timeless power source for demanding speakers. At $799 USD, especially if it includes original mounting plates or a clean condition, this is a smart, high-value acquisition with no meaningful caveats to raise.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
