The IN50 Signature integrated amp-preamp is manufactured with the greatest care: we choose the best possible components to achieve the highest level of sound performance. This rigorous search for perfection goes through the design of proprietary ATOLL circuits in order to preserve the integrity of the most subtle musical signals.
OVERVIEW
Atoll’s 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.
