A large influence on the "British" sound was the BBC. Live music broadcasts were more widespread over there and the BBC made great efforts to have high quality sound. Many of their engineers made contributions to audio; Spencer Hughes[Spendor] and Dudley Harwood [Harbeth] both spent most of their careers at the BBC, developing Bextrane, the first widespread plastic material for cones. The speakers they developed were intended first and foremost for the reproduction of the human voice and they are still among the best at it. Not as "Analytical" as many American top end speakers but unfailingly musical.
