ATOLL IN300 Evolution Integrated Amplifier

The ATOLL IN300 Evolution is a high-end integrated amplifier engineered for demanding audiophiles, delivering 150 W per channel into 8 ohms with exceptional clarity and control. It features a fully dual-mono design with twin 440 VA toroidal transformers, a premium AKM AK4490 DAC for high-resolution digital playback, and a robust Class A/B output stage. With extensive analog and digital connectivity—including XLR, USB, Bluetooth, and optional phono/DAC boards—the IN300 EVO is both powerful and versatile, ideal for anchoring a high-performance audio system.
