The STASIS technology was one of the great audio engineering “wonders” (engineered and patented by Nelson Pass) from the Nineties. And the Threshold amps that carried this technology is still one of the most coveted amps in hifidom. This S/300 MK.II is a later design that featured Optical Bias (which increases its desirability) which was a sonic improvement over the earlier models that didn’t have it. Bottom end now is tighter and the highs less dry. Technology was state of the art back then but the amp easily still rivals anything out there in the sub-$5,000 category. Power output is a robust 150W per channel and the built and finish is second to none. Threshold gears are very rugged and almost designed to last forever…. Anyway, we had this setup together with the FET-10HL preamp (which belonged to the same one owner from NEW) in one of our listening rooms and the level of clarity, power reserve, punch and dynamics was more akin to a much higher end and more expensive system. We have the FET-10HL for sale in another listing.
Cosmetically, the amp looks really good. Minor scuff marks/nicks here and there that are common with use but nothing major. Unit will be securely packed for safe shipping.
