At the International CES Expo in Las Vegas, Krell introduced the most revolutionary design change in its 33-year history: iBias™, a patent-pending new technology that uses the Class A circuitry preferred by audiophiles yet consumes far less energy than a traditional Class A amplifier does. Because iBias technology eliminates crossover distortion, it allows the low-level details, subtleties and spatiality of music to come through exactly as they do in a traditional Class A amplifier. Yet iBias also allows these new amplifiers to produce the nearly limitless dynamics that is the hallmark of Krell’s sound. Class A amplifiers have always been the preferred choice of audiophiles, and they’ve been a hallmark of Krell engineering for decades,” Bill McKiegan, president of Krell Industries, said. “But concerns about energy consumption have reduced some of the enthusiasm for Class A.
