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.

  • Revolutionary AAVA volume control
  • Power MOS-FETs in triple parallel push-pull configuration driven in pure class A
  • Current feedback principle and MCS+ topology in power amplifier section
  • Logic-control relays for straight and short signal paths
  • Tone control circuits
  • Strong power supply with large transformer
  • Option board slots provide capability for digital signal input and analog record playback
