The Reference 750 SEL monoblock amplifier continues the story begun 25 years ago with the introduction of the Reference 600; that is, to create the ultimate, vacuum-tube amplifier with enough power to drive any speaker, and to provide a musical experience unlike any before it. The Reference 750 SEL 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 SEL 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.
