Pure Class A power amplifier using power MOS-FET devices. Fully balanced signal paths as found in high-quality instrumentation amplifiers. Further refined MCS+ topology and current feedback design result in even better S/N ratio, distortion, and other performance parameters. Robust power supply and power MOS-FET devices in triple parallel push-pull configuration sustain an amazing 150 watts per channel into ultra-low 1-ohm impedance loads (with music signals).

Pure Class A operation delivers quality power: 30 watts × 2 into 8 ohms
Power MOS-FET output stage features triple parallel push-pull configuration
