The Corona Line - High end audio in its most beautiful form

MBL is well known for its innovativeness. And so when developed the Corona Line we did not simply translate the familiar from our large lines into a computer design. Instead, we conbined proven designs with innovations to create an entirely new line of high-end audio electronics.

We have taken a great step forward in amplifier design with our new 'Linear Analog Switching Amplifier' (LASA), which teatures an extremely low distortion level at all pitches and volumes.

Our USB converter technology has dethroned the conventional referance players of a number of product testing magazines. Our Corona CD player unites the world of CDs with computerfiles with unbelievable feeling. The Corona Line the is not a small noble line. It is far more and a step decisively ahead of its class.
















The system's heart or motor, the amplifier, has a special role to play as it carefully "amplifiers" the delicate musical signal and controls the loudspeaker, enabling all pieces of musical information to be bundled into a meaningful whole. The C51 provides the strong-hearted foundation of a simpler system by carefully combining the functions of the preamp and amplifier in one elegant chassis. No compromises here, discrete components fill the input section, our trail-blazing LASA technology provides a powerful and efficient amplifier... MBL to its core. For optimum channel separation and a distinct, true-to-life musical image, we have crafted the input stages from carefully selected discrete components. Full listening pleasure in half the space.
