The concept of the IN400se 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.

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.
