  • The D1100 digital preamplifier is a reference level stereo preamplifier and digital-to-analog converter (DAC) that supports all the latest high resolution file formats.
  • It features the most advanced DAC we’ve ever used and delivers an unprecedented level of performance so that all your digital music is reproduced with exceptional accuracy and authenticity.
  • Nine inputs are included to keep even the largest digital system connected. Three sets of balanced and unbalanced stereo outputs (one set fixed volume, two sets variable volume) connect the D1100 to your system.
  • The D1100 is a full featured, fully functional self-contained unit that can be used independently of any other preamplifier. But thanks to McIntosh’s engineering prowess, it can also be connected to and used in tandem with its analog equivalent, the C1100 Vacuum Tube Preamplifier.
  • Audio channels and power supplies are electrically isolated from each other to produce true dual mono operation.
  • Built from same polished stainless steel and hairline brushed black Titanium stainless steel as the C1100.
