Back in 1984 three young man in early twenties had no idea about anything other than the need to make things sound better, there was a salesman and two engineers, and they worked from two rooms above a shoe shop outside London, United Kingdom. They made amplifiers by hand and every single one was listened to and built by the people that designed them and owned the company. Passion was not adequate enough to describe their drive.
