The H4SE is an improved version of the H4A MK2. The H4A MK2 was in many ways the very corner stone of the Hegel amplifier range, but the development of the H20 amplifiers disclosed a significant potential for upgrade. The H4SE has received many of the technologies developed for the H20, including the Hegel Next-Gen technology in the input stages. This gives it a smoother, yet at the same time more rhythmic sound compared to its predecessors. Each channel of the H4SE is divided into completely separate voltage gain and current gain stages. The benefit with this design is a higher dynamic range, better pin-pointing of instruments and a wider sound field. The reduction of dynamic distortion all over the audible frequency range together with complete elimination of "transistor sound" makes the H4SE sound smooth and transparent without losing any details. Behind it's confident front panel, the H4SE has extreme power reserves and is capable of powering all known speaker systems. The H4SE can deliver a current output signal of more than 200A.
