This limited production Diamond special edition of Vincent Audio's SA-T7 preamplifier has a special story. Its existence is the result of an unexpected find: a few crates of prized German Telefunken tubes from decades ago, unused and in original condition. These NOS (New Old Stock) Telefunken PCF803 tubes are so valuable that Vincent's prestigious German designer Frank Blöhbaum decided to build a product around them. Frank chose the highly acclaimed SA-T7 MK Tube Preamplifier. But he knew that simply dropping these tubes into the existing SA-T7 circuitry wouldn't work. So, he ended up redesigning the audio circuit around the PCF803, ultimately achieving what he refers to as this preamp's "special sound." The result is the special edition SA-T7 Diamond, a preamp that has to be heard to be believed. But hurry if you want to hear it! Production is limited, and no more Diamonds will be built once the PCF803 tubes have all been used.
