Atoll Electronique AM300 Amplifier

The double mono design means the left and right channels are completely independent, each with its own power supply. This prevents crosstalk between channels, resulting in a wider, more precise soundstage and better separation of instruments.

Yes, with 150W per channel into 8 ohms and 280W into 4 ohms, it has plenty of headroom for most speakers. If you have particularly power-hungry floorstanders, you can even bridge the amplifier to mono mode for a massive 500W output.

MOS-FET transistors are known for their smooth, tube-like warmth and musicality. By using six per channel, the AM300 balances that natural character with the speed and control required for high-fidelity audio.

At 103mm tall, the AM300 has a relatively low profile, but it is quite deep at 360mm. You should ensure your rack has at least 400mm of depth to allow for proper cable clearance and ventilation.

While it runs warmer than a Class D amplifier, the AM300 is designed for efficient heat dissipation. Just ensure you provide a few inches of clearance above and around the unit to allow for natural airflow.

The AM300 has an input sensitivity of 1.7V and a high input impedance of 220 kΩ, making it compatible with a wide range of preamplifiers. It will perform best when matched with a high-quality preamp that can maintain a clean signal path.
