ACCUSTIC ARTS® AMP III – For those looking for a little more

The electronic of the AMP III – MK2 has been completely redesigned and retuned. The result is also here, a much higher performance with an even better sound quality.

The AMP III – MK2 is based on the amplifier technology of our legendary AMP II amplifier and is designed for customers seeking maximum power who also want audiophile amplifier performance. The AMP III therefore has the 4 separate final stage circuit boards from the AMP II and combines these in such a way that respectively 2 boards are available for each channel. Both these boards are also divided with an inverting and non-inverting signal component. The AMP III – MK2 with its symmetrical technology is therefore a completely unique power amplifier. An amazing 48 hand selected MOS FET transistors together with 2 enormous transformers deliver huge power.

One more result of the modernization and optimization of the AMP III – MK2 is, that it can now safely operate loudspeaker systems that have a minimum impedance of 2 ohms or less.

AMP III – MK2 highlights

  • Extremely powerful dual-mono high-power amplifier with completely isolated power supply for each amplifier channel
  • 40 selected MOS-FET output transistors of highest quality
  • 2 magnetically shielded and encapsulated toroidal core transformers of premium quality for highest output reserves
  • Optimum smoothing thanks to more than 220,000 µF power supply capacity; premium quality capacitors (“Made in Germany”)
  • Very high damping factor
  • ACCUSTIC ARTS® Damping factor linearization (switchable)
  • Professional protection circuit against clipping, HF oscillations and too high DC offset
  • Integrated switch-on current limitation for highest operational safety
  • Balanced input (XLR) and unbalanced input (RCA) – the inputs are switchable
  • All used components and parts are selected and of highest quality
  • Very high quality, gold-plated bi-wiring/bi-amping speaker terminal
  • Extremely stable, massive and resonance optimized housing, fully made of aluminium; inlay made of massive brass, polished and chromed
  • ACCUSTIC ARTS® AMP III – MK2 is “Handmade in Germany”
