In 1989, Cambridge Audio, then run by Stan Curtiswho is still active in hi-fi introduced their DAC 1. At about the same time, within a few weeks of each other, Arcam introduced their Delta Black Box and Musical Fidelity their Digilog. I forget who was first among the three. Arcam, I think. But the DAC race was on, led by the British. (There was even a DAC called the Dacula.) US companies got into the DAC race, tooat higher prices, of course.
