Delivering a massive 75 watts of pure, undistorted sound from its stereo/ambiophonic amplifier, Beomaster 4400 stood at the top of the range of desirability in the late 1970s. The technology was changing, and when compared to the Beomaster 1900, which was a runaway success, this receiver represented the old, sedate school with its more up-to-date cousin serving modernity and the way to the future.

Beomaster4400 replaced Beomaster 4000, with both models representing the style that Jacob Jensen did best. Perhaps that was the problem, expense apart, the whole of the B&O product range was beginning to look somewhat tired by this stage of its history and something new, more exciting, was needed.
