Atoll IN50 Signature Integrated Amplifier Silver

The integrated amp-preamp IN50 Signature is manufactured with the utmost care. We choose the best possible components to achieve the highest level of sound performance. This rigorous search for perfection involves designing proprietary ATOLL circuits to preserve the integrity of the most subtle musical signals.

Our 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.
