Atoll Electronique AM400 silver
This product is no longer available for sale!
Overview
The power stages have 8 transistors per channel, providing considerable energy that is perfectly controlled thanks to carefully designed audio stages. The connecting cables between the motherboard and the speaker outputs are made of pure, deoxygenated, silver-plated copper with Teflon insulation. These cables are custom-made by one of the best French audio cable manufacturers.
Similarly, the low series resistance filtering capacitors are made in France to specifications by a leading specialist. The polypropylene film structure coupling capacitors have been selected by listening tests from the high-end series of the greatest manufacturers. The speaker output connectors are made of solid copper with gold plating, chosen for their ability to transmit all the energy and micro-details of the musical message without alteration.
In bridged mono mode, the energy gain is colossal: this configuration is suitable for all systems where high power is required. The differential structure design allows for this transformation without altering the nuances of musicality; on the contrary, the gain in “sound matter” makes the listening experience even more realistic.
