The Threshold SA/1 monaural Power amps. Together with Mark Levinson Ltd, the Threshold company built high power solid state amplifiers even before Krell Industries – the name we often associate with highpower Class A amps – even existed. The principal designer of Threshold, Nelson Pass, grounded his firm in 1974 together with Rene Besné who took care of the PR, sales and beautiful multi-layered frontplates and stylish logo. In 1975 their first product was the Threshold 800A a so called sliding bias Class A amp. To his dismay this topology was shamefully copied by lots of other manufacturers that thought you could produce amplifiers with mediocre powersupplies a handfull of active components and a badge reading something like ‘New Class A’ or ‘Class AA’ but they never sounded as good as the original.
