The concept of the IN400 rests on our aesthetic and technical approach dedicated to optimal musicality. In mechanical terms, chassis is made from 2 mm steel and the front of 10 mm aluminum. Lateral curved heatsinks are manufactured in massive aluminum blocks by a completely unique process. The original design of the cabinet has been studied to best absorb mechanical vibrations and ensure perfect heat dissipation.

Electronic scheme is the result of long hours of updates that helped to optimize its operations and to refine the choice of components. Electric stages are rigorously double mono with a specific attenuator by channel and two ground star differentiated. Each component has been selected by listening and comparison test. The original scheme is optimized to refine the polarization bias currents and feedback.

Here is the Atoll CD 400, the IN400’s complement. It is equipped with many features amongst which a suspension mounted CD PRO mechanism. This unit has 8 regulated transformers (for a total 22000uf) complemented with a toroidal transformer of 170 VA. The conversion is handled by two Burr Brown PCM1794 DACs followed by a line output with differential stages equipped discreet components. Thanks to its coaxial, digital and optical inputs, it can be used as a DAC.

The ultimate goal is to provide maximum power with as much energy in all registers. It then gets a listen binding wide stereo image and fluidity, natural and harmonic wealth.
