A circuit concept that has bewitching midrange in both push-pull and single-ended amplifiers due to the low distortion. But unfortunately it is paired with low power, dynamics and excessive heating of the amplifier. Features that do not match the product profile of our popular integrated amplifiers 100%. It was therefore important to develop a concept that would bring the undisputed tonal advantages of this principle to life."}
