The D1100 digital preamplifier is a reference level stereo
preamplifier and digital-to-analog converter (DAC). Its 8-channel,
32-bit DAC is used in Quad Balanced mode with half of it dedicated to
the left audio channel and the other half to the right channel. It’s 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.

Enough inputs – 9 to be exact – are included to keep even the largest
digital system connected as 3 optical, 3 coaxial (2 RCA and 1 BNC),
plus 1 each of MCT, AES/EBU and USB inputs are onboard. The USB input
accepts up to 32-bit/384kHz signals and supports DSD64, DSD128, DSD256,
DXD 352.8kHz and DXD 384kHz playback1. All the other inputs
accept up to 24-bit/192kHz. The MCT input is a McIntosh exclusive and
allows for enjoying to the high resolution audio found on SACDs via the MCT450 SACD/CD Transport.
Three sets of balanced and unbalanced stereo outputs connect the D1100
to your system. One set of outputs has fixed volume while the other 2
have variable volume; the variable outputs can also be switched on and
off for additional user configurability.

The D1100 is designed for ease of use: all inputs can be renamed; its
4 data ports and 4 power control triggers are fully programmable; and
it has both IR and RS232 external control. For personal listening,
Headphone Crossfeed Director (HXD®) will bring a new depth and spatiality to your music.

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.2
Combining the two together with the included umbilical cable creates
the definitive analog and digital stereo preamplifier. When connected,
the C1100 takes over all control of the D1100 resulting in a single and
easy to use interface. Like the C1100, the D1100’s left and right audio
channels and power supplies are electrically isolated from each other to
produce true dual mono operation when used either by itself or with the
C1100. This isolation delivers absolute stereo separation and sonic

It’s housed in a beautifully polished stainless steel and hairline
brushed black Titanium stainless steel chassis – the same as the C1100
so the two will seamlessly blend with each other if used together. A
black glass front panel, blue meters, knobs, an illuminated logo and
brushed aluminum end caps complete the ageless McIntosh look. It can be
paired with a variety of amplifiers, room correction devices, speakers, CD players, streaming audio players​ and other source components to make a complete home audio system.
