When developing the AM400 Signature amplifier  , attention to detail pushed us to take into account all parameters, compare and listen to each component. The power stages have 8 MOS-FET transistors per channel which provides considerable energy, perfectly controlled thanks to carefully designed audio stages.  The connection cables between the motherboard and the speaker outputs are made of pure, deoxygenated copper, silver plated with Teflon insulation. These cables are manufactured on demand by one of the best French audio cable manufacturers. Likewise, the filter capacitors, with low series resistance, are made to specifications by a major specialist.

The gold-plated speaker output plugs have been selected for their ability to transmit without alteration all the energy and micro-details of the electrical signal. The connecting capacitors with a polypropylene film structure have been selected by listening in the high-end series of the largest manufacturers. In mono bridged mode the energy gain is colossal: this operation will be suitable in all systems where high power is required. The differential structure diagram makes it possible to carry out this transformation without altering the nuances of the musicality, the gain in “sound material” makes listening even more realistic.
