The ultimate integrated pure class A amplifier – Power MOS-FETs arranged in triple parallel push-pull configuration. Innovative AAVA volume control. Strong power supply with large toroidal transformer and high filtering capacity supports linear output progression of 120 watts/ch into 2 ohms, 60 watts/ch into 4 ohms, or 30 watts/ch into 8 ohms. Power amp section uses current feedback for optimum high-frequency phase characteristics and MCS+ topology.
