Atoll

The philosophy of Atoll Electronique is much more than efficient diagrams: 
It is a coherent approach and a rational design, implementing the highest quality components while providing an exceptional quality/price ratio.
Using metal chassis, aluminium front panels, and discrete component circuits polarized in class A for the preamplifiers and class A/B for the amplifiers gave us a solid product construction perspective. The power transistors we use are MOSFETs because they offer the advantage of the highest efficiency with outstanding audio performance.
