Circuitry Highlights Patent pending Krell iBias Class A technology allows our latest amplifiers to run in full Class A mode to full power while minimizing heat generation. All signal gain is realized in the current domain using discrete, proprietary, multiple-output current mirrors with extraordinary open loop linearity. There are no generic integrated circuits or op amps used anywhere. Current...[more]

New technology which does not hurt sonic imaging combines the so-called "wire to wire connections" with PCB techniques to deliver outstanding sound quality. A relay attenuator contains two independent blocks for each particular channel which has improved channel separation. This kind of volume control is being used in competing amplifiers only in a much higher price range. Gain control by 1dB, ...[more]
