Electrocompaniet AW 800M NEMO 2 Reference Monoblock Power Amplifier

The Electrocompaniet AW 800M NEMO 2 is the brand’s most powerful and advanced power amplifier, designed as the successor to the legendary AW 600 NEMO. This flagship monoblock amplifier delivers extraordinary power, precision, and sonic purity, making it a reference-grade solution for the most demanding high-end audio systems. Built in Norway with Electrocompaniet’s signature design philosophy, the AW 800M preserves the company’s globally recognized sound signature while pushing performance to new levels.

At its core is Electrocompaniet’s direct-coupled high open-loop bandwidth topology, enhanced with ultra-high bandwidth amplifier stages and an extremely fast slew rate. A newly engineered output stage isolates the input and driver stages from the load, allowing the amplifier to deliver immense power while maintaining exceptional control and ultra-low distortion. The result is a remarkably clean, dynamic, and detailed soundstage with effortless musical realism.

The AW 800M features a significantly upgraded power supply with massive filtering capacity and twin toroidal transformers designed to eliminate noise and deliver stable, high-current output. With versatile operating modes including mono, stereo, and bi-amping, this amplifier offers unmatched flexibility for system configuration. Finished with Electrocompaniet’s elegant matte chassis and precision-machined aluminum accents, the AW 800M stands as a true statement piece in both performance and design.
