The Legacy heads use an interconnection system made with gold on gold connectors in concert with multilayer circuit boards instead of wires with crimped on, tin connectors. Gold connectors will never corrode, and the multilayer circuit board provides complete shielding from outside interference.

Legacy heads are cooled using two fans that are temperature controlled. At low temperatures the fans are off, as the amplifier temperature rises the fans come on slowly and run faster the warmer the amplifier gets. Under normal operation the fans may not come on.

Legacy heads use the latest available digital power amps with switch-mode supplies. These deliver a punchy driving sound at a fraction of the weight and power consumption of analogue power systems. They are safe down to two Ohms and operate from 100V to 240V mains.

An all-aluminum anodized package reduces weight and provides a durable finish that will never corrode or discolor. Extruded aluminum parts give the amplifier sleek look from all sides. The graphics are etched into the anodized finish and will never wear off or fade with time. Convenient handles provide knob protection and make moving a breeze.

GK produces all its circuit board assemblies in house using state of the art surface mount technology. Using this technology gives us access to far more material options for our designs and makes for a more reliable product.
