Krell 300i Integrated Amplifiers
Krell Integrated Amplifier K-300i incorporates a newly developed amplifier circuit design with Krell iBias™ technology, delivering 150 Watts/Channel into 8Ω and 300 Watts/Channel into 4Ω. iBias provides the sonic benefits of Class A operation without the excessive heat and power consumption of traditional Class A design.
With the digital option installed the K-300i becomes a world-class DAC with the connectivity and features to support the latest digital music formats. An ESS Sabre Pro DAC configured for high current output performs the digital to analog signal conversion for uncompromised reproduction of digital music.
