Stereo Integrated Amp/DAC

Compact in size (2/3 width) yet offering high power output and exceptional resolution, this integrated amplifier with on-board DAC is ideally suited to driving ATC’s small & mid-size passive loudspeakers.  Understated styling makes it easy to integrate with partnering equipment while its small footprint occupies very little space in the home.

Key Features:

  • 2 x line level analogue inputs
  • 3 x digital inputs: USB, Coaxial, TOSLINK
  • Premium AKM 32-bit DAC
  • USB digital input supports up to 384kHz PCM and native DSD256*
  • ATC Discrete MOSFET Output Stage with 100W/Ch. Max Cont. Power
  • Headphone amp with discrete output stage
  • Handmade in England
  • 6 year warranty

*DSD256 support via PC only (up to DSD128 via Mac)
