Audio Research Reference 750SEL

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

Ease and musical momentum roll from this amplifier like the ocean.

Listening to Reference 750SEL 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. Herein lays the breath of the performer, the pick against the string, the brilliance of a full orchestra.

With sixteen KT150 power tubes on tap in each channel, The Reference 750SEL delivers over 750 watts of power into speaker loads of 4 to 16 ohms through its massive, custom-built power and output transformer.

In the largest of listening salons, and on the largest loudspeaker designs, REF750SEL thrills with gravitas and musical intent. Pull out all the stops.
