ATOLL AM300 Evolution Amplifier

The Atoll AM300 Evolution is a high-performance stereo power amplifier designed for audiophiles seeking exceptional sound quality and versatility. Delivering 150 watts per channel into 8 ohms and up to 280 watts into 4 ohms, it can also operate in bridged mono mode to provide 500 watts into 8 ohms, making it suitable for a wide range of speaker systems.

Featuring a dual mono architecture with two 440 VA toroidal transformers and high-quality components like low-ESR capacitors and MOS-FET transistors, the AM300 ensures precise and dynamic audio reproduction. Its balanced XLR and unbalanced RCA inputs offer flexible connectivity options, while the 12V trigger input allows seamless integration with compatible preamplifiers.

The amplifier's robust construction, including an 8 mm brushed aluminum front panel, not only provides durability but also adds a sleek aesthetic to any audio setup. Handcrafted in France, the Atoll AM300 Evolution combines power, precision, and elegant design, making it a compelling choice for discerning listeners.
