Product Description
The Reference 250 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 is outfitted with the KT120 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.
From the moment the music begins, the foundation of an exceptional musical experience is evident. Sound emerges from an inky black background, revealing microdetails and performance cues typically reserved for the live performance. Substantial, fundamental bass underscores the event with resolution and textural accuracy. Space around performers and groups of instruments stretch before you onto a lifelike stage with scale and body. Dynamics swing from silent passages to grand fortissimos without effort or strain. This is high definition listening.
