In the early days British amplifier manufacturers were renowned for building low-powered amplifiers. Exceptionally high-quality low-powered amplifiers, but low-powered all the same. It was their penchant for this that provided American amplifier manufacturers with their first foothold in the audio industry, because they became equally renowned for building high-quality high-powered amplifiers. So if you wanted a low-powered amp you bought British and if you wanted a high-powered amp you bought American.
One person who never bought into this paradigm was Antony Michaelson, who founded Musical Fidelity in the UK in 1982 and is still its sole owner and managing director.
