REFERENCE 750 SE

AMPLIFIER

The Reference 750 SE monoblock amplifier continues the story begun 20 years ago with the introduction of the Reference 600; that is, to create the ultimate, tube-driven amplifier with enough power to drive any speaker load and to provide a musical experience unlike any before it. The Reference 750 SE redefines all expectations of what is possible from an amplifier in a music playback system. It is the culmination of everything Audio Research knows about amplifier design and manufacture – High Definition in its purest, most dynamic form.

Listening to Reference 750 SE monoblocks in a high performance system is a transformative experience; under total control, speakers disappear from the listening room and the listener is transported into a three-dimensional realm where music takes on a palpable, tangible form. Details from source material are resolved against a black background, painting images in space with vivid reality. Bass becomes the foundation on which this living performance develops, produced with startling temporal and timbral accuracy. Here is the breath of the performer, the pick against the string, the brilliance of a full orchestra.

The Reference 750 SE is prepared to deliver 750 watts of power into speaker loads of 4, 8 and 16 ohms. This is achieved by the use of a massive, custom- built power transformer delivering current from sixteen KT150 vacuum tubes. Thanks to extensive testing and strict selection of tubes, the amplifier requires little maintenance and obviates the need for costly and sonically deleterious automatic bias systems. Power supply regulation is also achieved by 6550WE and 6H30 vacuum tubes. Tube bias is controlled by two KT150 tubes, each driving a bank of eight tubes.
