VIRTUS A3 • Performance Line

Integrated hybrid amplifier

 

 

Virtus A3 is an all-in-one dual-mono hybrid amplifier in Class A/AB with a full range of digital and analogue inputs – including power amplifier, phono preamplifier, headphone amplifier and DAC.

Highlights

 

  • Four devices in one housing: a hybrid power amplifier in Class A/AB, a phono preamplifier, a headphone amplifier and a DAC.
  • The analogue and digital signal paths are designed in a dual-mono configuration with fully independent, multi-stage regulated power supplies per channel.
  • A fully discrete phono preamplifier supports both MM and MC cartridges.
  • A discrete, fully balanced, balanced headphone amplifier stage enables both unbalanced and balanced headphone outputs.
  • The Virtus A3 offers Class A preamplifier outputs – both unbalanced and balanced – for connecting external power amplifiers or active speaker/subwoofer systems.
  • A specially developed, highly efficient cooling system with heatpipe heat sinks.
  • The control knob is securely housed in a precise double row bearing with a touch display in the centre.
  • Recommended retail price: 5.999,00 €
