The concept of a large mono-block amplifier is to provide control to a speaker. Â The difficult part of the job is maintaining finesse and musicality while doing it. Â Audio Research has produced some of the most critically acclaimed products during its 42-year history and the new Reference 250 SE aims to break new ground. From the moment the music begins, the foundation of an exceptional musical experience is evident. Â Sound emerges from an inky black background, revealing micro-details and performance cues typically reserved for the live performance. Â Substantial, fundamental bass underscores the event with resolution and textural accuracy. Â Space around performers and groups of instruments stretch before you onto a lifelike stage with scale and body. Â Dynamics swing from silent passages to grand fortissimo without effort or strain. Â This is high definition listening. Â Â The Reference 250 SE features new enhancements outside as well as major performance advances inside. Â First, you will notice a more modern, monochromatic appearance, including a new front panel with a small aluminum power button. Â An analog meter with adjustable illumination is set in the front panel is capable of displaying power output and tube bias settings. Â A new low turbulence fan provide effective yet silent cooling. Â Internally, the Reference 250 SE is outfitted with the KT150 output tubes and a bulk power supply 50 percent larger than its predecessor. Â Connections include accommodation for 4, 8 or 16 ohm speakers, an XLR input as well as 12 volt trigger connections.
