This is a buyer’s market for robust, service-friendly Bryston power amps, and the US$4,000 asking price for a used Bryston 6B‑SST² stereo amplifier is ambitious compared to typical used listings. The closest verified comparable is a clean, used 3‑channel 6B SST2 at US$1,895 on Reverb, and stereo Bryston SST2 models (3B/4B/7B) typically trade in the US$3,850–US$9,200 per pair range for the SST2 line, implying a single stereo unit would usually land well under US$4,000 unless it’s pristine or includes extras. Unless this listing is original-owner, fully documented, and includes heavy accessories, the price sits above the median and feels seller-leaning.
The 6B‑SST² is well-regarded for its rock-solid Bryston build, 300W/8Ω per channel (500W/4Ω), and legendary 10‑year warranty coverage that still matters if transferable, making it a reliable, high-current stereo amp for demanding speakers. Its upside is rarity in stereo form, long-term durability, and Bryston’s service network; if the unit is clean, tested, and includes the original warranty card or power cords, it becomes a solid buy despite the high ask. Only flag concerns if condition is unknown or warranty is non-transferable, since at US$4,000 you’re paying for confidence as much as performance.
