About the Sigma AMP2

The Classé Sigma AMP2 is a two-channel stereo amplifier delivering 200 watts RMS per channel into 8 ohms and 400 watts into 4 ohms. It employs a Classé-designed switch mode power supply with Power Factor Correction, providing over 1,000 watts of clean and stable power efficiently. The amplifier uses a new Class D amplifier topology that offers a wide dynamic range, smooth and extended frequency response, and rich harmonic detail for stunning sonic performance. Its compact size and low heat dissipation make it suitable for high-performance audio systems. The AMP2 features balanced and single-ended inputs, a voltage gain of 29 dB, and a very low harmonic distortion of less than 0.018% at 1 kHz. It has a frequency response of 10 Hz to 20 kHz (-1 dB into 4 ohms) and a signal-to-noise ratio of -100 dB at peak output into 8 ohms. The amplifier supports mains voltages from 100V to 240V at 50/60 Hz and weighs approximately 22 pounds (10 kg). Dimensions are 17.00" (W) x 14.57" (D, excluding connectors) x 3.75" (H). It is designed for audiophiles seeking high-quality sound with efficient power delivery in a compact chassis.
