Description
Atoll IN300 : Integrated Amplifier
The IN300 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.
