Electrocompaniet TW600 Nemo Mono Blocks

The Electrocompaniet AW600 NEMO is a monaural Class A reference power amplifier designed to deliver exceptionally high levels of power, current capability and low distortion. Built around Electrocompaniet’s proprietary amplifier architecture, the NEMO is designed as a dedicated monoblock for demanding high-end stereo systems where substantial power delivery and precise control are required.

The AW600 delivers 600W into 8Ω and 1,200W into 4Ω, with a maximum peak current capability of more than 150A. Its DC-coupled signal path, extremely low output impedance and damping factor greater than 850 are designed to provide a high degree of control over the loudspeaker load.

The NEMO uses balanced operation exclusively and features a substantial chassis measuring 465mm wide, 450mm deep and 288mm high. Weighing 41kg, each amplifier is built as a dedicated monaural power source for high-performance loudspeaker systems.

Power & Operation

Power Consumption: 230W with no load or signal

Mains Compatibility: 120V / 240V, 50Hz / 60Hz measurements

Warm-Up: Electrocompaniet recommends allowing two hours of warm-up after the amplifier has been switched off for optimal sonic performance.

Ventilation: Due to its Class A operation, the AW600 normally becomes warm during operation. The manual specifies that the ventilation area must not be covered and recommends at least 3–5cm of clearance to the sides and 5–8cm above the amplifier.

Construction & Design

The AW600 is designed as a dedicated monaural amplifier, allowing each channel of a stereo system to have its own independent power amplifier. Its substantial chassis houses the Class A amplification circuitry and power supply required to deliver its high continuous power and current capability.

Electrocompaniet specifies a very low output impedance of less than 0.009Ω and a damping factor exceeding 850 across 20Hz–20kHz. The amplifier is also DC coupled from input to output, maintaining a direct signal path without an AC coupling capacitor in the signal path.

Conclusion

The Electrocompaniet AW600 NEMO is a formidable high-end monaural power amplifier, combining Class A operation with 600W into 8Ω, 1,200W into 4Ω and more than 150A of peak current capability. Its exceptionally low output impedance, high damping factor and extremely low measured distortion demonstrate the engineering emphasis placed on power delivery and loudspeaker control.

With balanced-only operation, a DC-coupled signal path and a substantial 41kg construction, the NEMO is designed for serious reference-level systems where amplifier authority and refinement are equally important. Its considerable power reserves make it particularly suited to demanding loudspeaker loads and high-performance stereo installations.

For listeners seeking one of Electrocompaniet’s most powerful and ambitious monaural amplifiers, the AW600 NEMO combines Norwegian engineering, Class A operation and exceptional power capability in a statement-level amplification platform.
