The concept is based on technical and aesthetic choices dedicated to optimal musicality. Mechanically, the chassis is made of 2 mm steel, and the front face is 10 mm aluminium, brushed, micro-blasted, and anodized, with high-precision engraving. The side heatsinks are machined from solid aluminium blocks to absorb mechanical vibrations and ensure perfect heat dissipation.\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eOur balanced MOS-FET amplifier circuits offer excellent harmonic gradients and have no memory effect, every moment, the current is immediately delivered to your speakers. This is one of the secrets of the musicality that ATOLL amplifiers enjoy.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv class=\"title title_small\"\u003e\n\u003cdiv
