The concept of a large monoblock amplifier is to provide control to a speaker.  The difficult part of the job is maintaining finesse and musicality while doing it.  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.
 
The Reference 250 SE features new enhancements outside as well as major performance advances inside.  First, you will notice a more modern, monochromatic appearance, including a new front panel with a small aluminum power button.  An analog meter with adjustable illumination is set in the front panel is capable of displaying power output and tube bias settings.  A new low turbulence fan provide effective yet silent cooling.  Internally, the Reference 250 SE is outfitted with the KT150 output tubes and a bulk power supply 50 percent larger than its predecessor.  Connections include accommodation for 4, 8 or 16 ohm speakers, an XLR input as well as 12 volt trigger connections.
