Description

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.

The Reference 750 SEL delivers over 750 watts of power into speaker loads of 4 to 16 ohms. This is achieved by the use of massive, custom-built power and output transformer delivering current from sixteen KT150 vacuum tubes in each channel. Thanks to 48 hours of burn-in, followed by thorough testing and careful matching of tubes, the amplifier requires little maintenance. 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 KT150 output tubes.

The SEL is the last version of the 750-series, produced in a limited edition of ten pairs. Using the latest and best parts available, the SEL version includes 23 new wires and 26 new capacitors as part of a stunning sonic transformation. The best vacuum-tube amplifier in the world just got better.

Audio Research was founded by William Z. Johnson, whose efforts almost single-handedly revived vacuum-tube designs. Many industry observers consider Johnson one of the true originators of the concept of "high-end" audio as it exists today.  Audio Research products have demonstrated lasting residual value with many attaining "collector" status.  As Audio Research’s premier audio specialist retailer in America, Overture invites you to experience the incredible audio performance of Audio Research.
